mp4 plays but no audio - MDA II, XDA II, 2060 General

Now I've read a lot here and I've tried Quicktime 6, mpegable ds decoder and 3ivx directshow filters.
They all work more or less (i like 3ivx best), but NONE of them plays the audio.
However the camera application on the ppc can playback video and audio.
What the hell is this? And I dont like Motion JPEG avi cause it's too big.
Converting also seems to be no option: I tried Riverpast Video Cleaner and a heavily upgraded virtual dub mod, but they can't even read the video. Quicktime Pro 6 can at least import the video, but no audio again.
Any ideas?

If someone wants to do more research, here are two good sites concerning mp4 players:
http://www.audiocoding.com/wiki/index.php?page=Software+Audio+Players+for+Windows
http://www.rarewares.org/
I've now tried WinMPG Video Convert and the Philips Platform4 Player - only video, as always.
I suppose the audio codec used is not the mp4 AAC LC (low complexity) codec because that's the most common one which can be played back by any mp4 player.
btw, mp4UI shows me a video and a audio stream (like most othre applications), but I can only export the video file and there is no information on the audio codec used, seems to be unknow to any program.
I tried several recorded mp4 files, always the same, and they DO playback video+audio on the ppc.

I'm sticking with MJPEG Avi
That's about 100 kB/s so I can hardly record more than 5 min. But hey who needs to? At least it can be converted by quicktime uncompressed avi export in no time, and then encoded to whatever you want.
More annoying is the fact that I need to remember getting the file off the pocket pc pretty soon because otherwise I will run out of space. I'd prefer taking a series of snapshots and carrying them around with me.
Well copying the file via USB will take almost as long as the video duration is, and a storage card can't be used because it decreases the recording frame rate significantly.
Motion MJPEG also seems to catch more redundant frames (the same picture in two frames) than mp4, but it's still okay.

cant you just record to your device and then copy the recording to your sd card manualy ?

Yes I thought of that, it would approximately take the same time as the video duration is. If you really need to do another recording while on the go, you can do that to free your memory.
btw, I chose divx5 250 kbit CBR + mp3 in virtual dub, only took a few seconds to encode a minute and now I've got a file that can be played back equally well on both machines. I'm using beta player for pocketpc, and it plays fine in fullscreen using the ati imageon chipset. File size is comparable to choosing the mp4 format in the first place.

It works now
mp4 video+audio works with quicktime!! hooray!!
Quicktime always told me it couldn't find the software needed on the server.
But when I opened the mp4 file today, the automatic download of the audio codec succeded.
Even with disabled firewall qt couldn't download the software before. Strange.
And I can export it to uncompressed avi if I need to edit the file with other programs.

mp4 video play back on PC

Hi Folks,
I just took for the first time a video clip with my Magician today, and had the Camera settings to
Capture Mode: Video
Capture Format: MPEG-4
Capture Size: Large
it produced a nice video clip file with in the .mp4 format (lets not talk about the quality)
I copied this file over to my SD card, and from there to my PC to play here.
It played by default using Apple Quick Time (7.0.3), no probs.
I tried to open it with WMP10 on my PC, and only got the sound, not video.
I was assuming, that a video clip taken with a Microsoft product (Magician WM2003) would play by default using the Microsoft pendant on the PC (WMP10), and MS does not rely on a 3rd party software (QT).
Any ideas what I'm doing wrong, or if I'm just missing the right codec on my PC to play back the file ?
Thanks

Correct me if i'm wrong but i do believe the camera program on modern HTC devices (like the Magician) is made by HTC itself and not by MS. So it's possible it uses different kind of codecs.
MS isn't allowed to ship a lot of codec with WMP. Only some basic and MS-made codecs. So you have to rely on third party apps/codecs to play the .mp4 files.
Hello Torklemm
You can use the VLC Player to Play almost any type of media including the mp4 , 3gp etc etc .
here is the link to download it - h**p://www.download.com/VLC-Media-Player/3000-2194_4-10267151.html
You can also install the Nero Digital MPEG 4 AVC h.264 dshow decoder , after i installed this , my wmp ver 10 was able to play the Mp4 video files.
Cheers.

very useful decoder!
but only motion decoding not audio track.
i see only motion without sound.
Hmmm , That is Strange Vigor_ , I thought the audio recorded in the video format of Magician was either mp3 , wma or wav . . . all 3 being suported by wmp. Will have to check this Thanx.
It's none of those. The audio is AMR Narrowband, whatever the blazes that is! I've been having the same problem converting it. AMR doesn't seem to be supported by much.
mp4 format
You should use a plugin or converter program. For plugin Ulead video suite v9.0 is the best solution.For convert purpose I offer IMTOO program.Another way is using avi format instead of mp4
Where do you get that Nero Digital dshow decoder? A Link would be nice.

How to do it for free, though it's a ton of work
Okay, I've successfully done it now. My biggest problem was that imTOO 3gpp costs money, and I just couldn't justify spending the money on it.
There's probably a few different ways to do this, but here's how I've done it:
1) Separate the Video stream from the audio stream
I used Microsoft Graphedit for this. It comes in a Microsoft SDK, but if you google it, you can find it.
When you open graphedit and select render the file, you'll get a message saying that part of the stream isn't recognised. That's the AMR audio. That's step 2, so ignore. Assuming you've got an xvid mpeg 4 codec on your machine already (and I suspect also a 3ivx codec), a graph will show up starting with your video file and ending with a video renderer. Click on the video renderer, delete it, and click on the xvid decoder and delete it. Then add a filter called file writer to the video stream coming out of the 3ivx media splitter.
Run that and you have an xvid mpeg-4 video stream with no audio.
2) Separate the amr audio stream
I used Miksoft 3gp decoder for this. For some reason I couldn't do video with this tool, so I just clicked the "convert audio only" option. It gave me a PCM .avi file.
3) Mix the two together
I have used two programs for this, both locatable through google and both freeware. Virtualdub and TMPGENC.
Virtualdub is handy if you have to rotate the video stream. I don't think you can use virtualdub to finalize the video because the .avi sound file kicks up an error for me. But the video I wanted to convert was filmed on my JAM with it held lengthwise (aka 320x240), so when the file is normally viewed, you see it 240x320 and have to tilt your head.
I prefer to use TMPGENC and end up with an MPEG-1 file. Here's why...
You input the xvid video file as the video source, the .avi pcm audio as the audio source, under advanced, select "Full screen (keep aspect ratio)" instead of the "full screen" that is presented there, and then let her run. You end up with a video in mpeg-1 that is formated to 352x240 (NTSC vcr resolution), but with black stripes above and below so that the image isn't stretched or distorted, like it would be if you just went with "full screen". You can then convert that into an avi file with whatever software you want.
It's a ton of work to do, but for me, it was a better solution than spending another $30US on something I'd use minimally. I also do a fair bit of video work, so I had all the other tools and codecs handy.
Good luck!
Hi
I use apples Quicktime - pro can also convert to AVI's.

The way I did it was to get the K-lite codec pack. Google it and don't download any versions from places that try to charge you for it, it's free. Also be aware of dodgy sites that may include spyware/malware with it. I've been stung a couple of times.
Then nearly any freeware converter will work. You can also play them in WMP.
Errrr...yes, that would seem to be a "faster" way of doing it...
screen capture
hmmm, need help...can't seem to capture images (using the screen capture button) when playing mp4 files on the vlc player...i've imported the image on adobe photoshop but it was distorted...help?
this is for info in relation to the original post
I too could not play my mp4 videos on my PC with sound and tried all the various players and plugins but this link from last year worked

Trinity video format

I've seen some information spreaded in the forums about video recording on Trinity, and had some troubles watching them on a desktop computers, so here is the results of my research, and the doubts i Still have:
Videos recorded on trinity with maximum quality CIF:
resolution:352x288
Framerate:15fps
container: MP4 (3GPP)
Video codec: MPEG4 (ASP)
Audio codec: AMR - NB (Narrowband)
To properly play videos on your desktop computer you need to install a directshow filter called MP4splitter.
-It is possible to convert video to AVI format (lossless) using mp4cam2avi, but it doesn't work with audio.
-The AMR format is not easy to edit or to transcode to other formats, and it's not possible to use as audio stream on a AVI container (not sure).
Questions
Is there a program to merge several mp4 together lossless (no re-encoding)?
Is it possible to set up another resolution to be used on the video (i.e. 640*480) as this is not a hardware limitation?
Is it possible to use another codec for the audio stream?
Is it possible to use another framerate?
- By editting registry I'm able to change framerate (HKLM\Software\HTC\Camera\Recparam)
Mediacoder
I use Mediacoder to convert many format of video (recorded on a dvd from TV...) on my htc : choose MP4 and use TCPMP to read it.
Video Conversion
Hi n0t,
Have a look at NCH Software - www.nch.com - and find a program called Prism Video Converter. It can be downloaded as a trial and expires after a while but long enough to try out. It works perfectly and is very simple to use. NCH has a wide selection of software, especially conversion from one format to another. Some programs are free but all are downloaded as trial versions.
Hope this helps
Adam

- MP4Box is a command line that does it, YAMB is a GUI that works fine with it (and it's free). It can split, join and extract streams from MP4 or 3GP container. This way it is possible to edit lossless the video streams.
-I want to be able to edit and apply some filters to the clips with virtualdub. To transcode the video stream to an avi container (lossless) I can use MP4Cam2Avi, Mediacoder, or Super. But I have to convert audio to PCM WAV to use it in virtualdub, as AMR can't be used in an AVI.
Stream Video
Is it possible to make a live video broadcast from trinity (not using videocall)?
This way with an internet connection, it would be possible to send a stream to a computer anywhere...

A tool to convert video to media player with hardware accelleration with mencoder

The main goal is to be able to use the hardware accelleration inside the X1. Or, only media player are able to!
Nor TCPMP or COREPLAYER use hardware.
But it was a pain in my ass to find a way to make a script able to convert a full directory fill with videos, with subtitles, and not to manage what is convert. And Free!
The way of thinking is:
I download a lot of free videos inside a unique directory, i have make this one the repository of my download.
I launch my script every night before sleeping
And I don't want to manage what is converted or not and i don't want to launch a application, i want something full auto...
So i make a full automation script.
I work under vista, so i'm not sure that's working under other windows.
it convert:
.avi
.mkv (with subtitles inside)
.flv
.mp4
.mpg
it takes subtitles:
.ass
.srt
.ssa
.mkv (it search inside itself)
to download:
http://dl.free.fr/qlBn0C2oj/ppc-conv.rar
clik on the "Télécharger ce fichier", sorry i'm french and don't know other file sender free
So how to do?
Extract the directory where you want
no need to setup anything
To convert:
1- you put your videos inside the dir VIDEOS
2- you start the "LANCE.BAT" inside main dir
3- you wait some hours
4- you transfer (with a copy! not a move) the .mp4 files inside the PMP dir on your X1
To clean when you have watch a video:
1- remove the files inside VIDEOS
2- on the next convert it will remove it from the PMP dir
Technical information:
Organization of the dir:
+---apps...........<- Main dir with the application
¦ +---.mplayer.....<- used by mencoder
¦ +---codecs.......<- used by mencoder
¦ +---mkvtoolnix...<- used for extract subtitles inside the mkv
¦ +---mplayer......<- used by mencoder
¦ ¦ +---conf.......<- used by mencoder
¦ ¦ +---font.......<- used by mencoder
¦ +---temp.........<- used for temporary step
+---pmp............<- where the final videos converted appears
+---temp...........<- used for temporary step
+---videos.........<- Where you put your videos and subtitles
Video are encoded into 640x360 1008kbit/s
Sound into aac 128kbit/s
works very fine in full screen
PS:
i share with you because i have try so much things and pass so much times to find a way, so i guess peharps someone else on earth wants this?
If you don't like it, don't download it
If you want more type of videos format send one to me and i will try
If you have problems says to me i will try to help but remember: it was a selfish script for me
Merci,
I will give it a try. I suppose that the settings wil give the greatest quality possible on an X1? ThanX once again

yes, i have try better resolution and better quality for no visual difference and much more lag.
With these parameters i'm on the border. sometimes some very high details scene are laggy
I bought core player. What are the best settings for it for the x1? Right now mine is on Outpu: qtv display
Video quality high
Smooth Zoom: only for 50%
Dither: off
Does it always use hardware acceleration or do I have to turn it on?
Thanks!

you cannot have hard accel with any other application than media player.
So you need to make a special mp4 file to be able to read it with it. It's the goal of my script
There is a huge gap in quality between them.
Really? I thought the whole point of core player was codecs and hardware aceeleration. I guess I'll give your script a go then.
Thanks.
even without hw acc, mine still playback a 800MB DivX/Xvid .AVI movies just fine with coreplayer.

sync audio w .avi in adv setting
vid xvid/divx around 600-650 x 300-350 res

audio mp3/aac 2chnl around 120kbps
it's not 100% smooth but enjoyable
I just tried Videora, a free iPod videoconverter.
Videora Website
Settings for Videora:
1. Power mode.
2. Choose File to convert.
3. Choose Destination Folder.
4. Choose a Title for the converted movie (Optional)
5. Choose Device = iPhone 3G
6. Choose Profile = MPEG4 480x320 768kbps Stereo/128kbit 2-Pass
7. Press Start Converting
Works really good, the video runs really smooth.

driver? does is it mean that you add something to your coreplayer?
no it's provided in coreplayer, in fact it's the default set in core if you're using qtv output in core.
try hard reset and install core again from fresh start; i've got some problems too a while ago and wasn't able to playback any video correctly at all; after hard reset those problems are gone.
Not to bug again about this, but doesn't CorePlayer not support Hardware acceleration on the XPeria? Doesn't Sony's player support it?
Many thanks nusul - I will give this a try! Appreciate your work on this
Tried to convert video but stript just flashes some opened windows but does nothing.
tried AVI/MP4 files in Video folder, no luck
Sorry, I have read this thread but I still have to ask for proper confirmation; you only get HW acceleration with Windows Media Player? So not when using the SE Media Experience panel?
I ask because I find the panel much faster when playing video than with Media Player (which takes at least the 1st five seconds of a movie to switch to landscape!!)

Lagfree playback of .MOV files

Sorry to start another one of these threads but after hours of searches on xda and google I want to know what my best route is for playback of .MOV files.
I have a Contour HD helmet cam that captures video 720P 60fps. It's only format choice is .MOV. On the a500 I have tried all the major video players and codec packs but what I get is super slow playback or no video playback. What I have been doing is transcoding the files using the Handbreak 720 baseline preset and that works pretty well 80% of the time. Sometimes the files are unplayable (not sure why).
My goal is to be able to take the card out of the cam and put it into the a500 and review my files without transcoding. If this isn't possible I will just continue to use my netbook for reviewing the files while I am away from home. Ideas? Thanks
According to this,
http://helmetcameracentral.com/2009/04/27/vholdr-contourhd-the-worlds-first-hd-wearable-camcorder/
the ContourHD does either 720p @29.97, or 480p @59.94. Video uses Main profile. The sample 720p clip uses a 5.6Mb/s bitrate, the 480p uses 3.3Mb/s. Both use 64Kbs mono AAC. All are within the stock player's capability.
No need to transcode, just a remux to MP4 container. Try the below,
"Use MPEG Streamclip (http://www.squared5.com/) - Open MOV file and Save as - change file type to MP4."
Thanks for the response. I will try the link you provided and a simple renaming of the file to .MP4 also. It's funny because the first time I tried to play a file on the a500 from the Contour I swear it played flawlessly but now they all play in super slow motion.
Update:
Ok, that worked and was pretty fast on my work desktop (older dual core). I am still hoping for a non converting/re-coding solution that I can use in the field. I was hoping to review videos while camping using the a500.

Help - Vid recording wont playback

Hi Guys,
Hoping someone can help me out here.
I made a Video recording from my gs2 (Stock firmware)Superfine, Max Resolution, Default camera app. 3.99gb File Size (I think this could be a factor, my other smaller recordings play fine - Maybe someone could try record to max and see if it playsback on PC (the recording automatically stops when it reaches 4gb i believe) )
Its recorded as a Mp4 file. (when i inspect it via my gs2 it says 3gpp format).
It plays fine from my gs2, however it just wont play on PC.
Tried VLC and also download various codecs, but still no luck. Also tried about 6 converters but none of them could even load the file.
Would really appreciate any help!
cheers.
You can play it back with a video player that supports mp4 H264 playback.
I use the x264 codec plus Media Player Home Cinema or Apple's Quicktime to play back.
