As I don't see much of a discussion on this....
I got the A7 not only for its power ( which it does everything 3d wise crazy good ) but also for its video/hdmi...thing is I can not seem to get videos working nicely with this unit.
Ive tried 480p and 720p videos in both mp4, mkv and avi containers at varying encodings ( xvid, h246, ect ) and all of which either "chop" or just are waaay too slow to be considered playable.
I've tried Vplayer, arcMedia, Rockbaseplayer, imbedded player.... running out of things to try to get videos nicely working on this thing...
Sad...as it has a nice HDMI port...
Anyone tried to get videos working on this and if so have you gotten better results?
Thanks
yes MP4, AVI & MKV does work but the h264 codec that's used for the video must be in baseline or main profile level. It does not support High profile. I realized this when my own encodings did not work.
n some ways this is sort of silly as High profile would give you the best encoding option for 1080p/720p videos
What's siller is that the A7 does read NTFS (as far as I can tell) so having a full lenght 720p or 1080p is really sort of tough with a 4GB limit. To get good qaulity for a 2 hour 1080p movie you are definitely going to go over the 4GB limit

Any way you can do a quick sample of a video? of both 720p and 1080p?
I'm curious as I may return it if I don't get the quality I'm looking for over hdmi...
Thanks for the quick response and much is appreciated.
Cheers
I just got my A7 and I've been playing with the video a little.
I used Nero Recode to encode to the target of 720 Main Profile (3.1 CABAC 2 Ref Frames) AAC LC 192mbps. It actually worked! I'm not saying it was great, but I don't know of any mobile device that supports CABAC @ 720p (It crushes older PCs and that tablet that starts with an "i"). I may turn it off and try again.
I agree that 1080p is going to be hard if not impossible to wedge into 4GB. I would question why you would even try it. 720p looks really good unless you plan on projecting it.
Anyway, I plan on playing with MP4 and probably WMV. I was really suprised that I couldn't get either a .ts or .m2ts file to play. These are generally easier to decode because the container is less complex than .mkv or .mp4. I may try the PS3 trick and rename it to .mpg to see if it plays.

Just played a 720p (1280 x 528) WMV (VC1/WMA Pro) flawlessly. I'll cook up a 1080p one today. VC1 doesn't do as well at low bitrates as H264, but it's easier to decode.
A couple issues I noticed:
1. Connecting the HDMI Port sometimes kills the touch screen. Putting the unit into standby seems to recover
2. The volume affects the sound level on HDMI, so make sure it's cranked (weird)
3. I could only get 2 channel out from WMA Pro 5.1. I'll have to try something with AC3/AAC. I'm guess it will have the same issues.
4. I couldn't get audio on my old TV (It is kind of a POS). Audio worked via my receiver.

With main profile you should be able to go up higher than 3.1. As for encoding 1080p well, if I or my friends have a 1080P TV why not? (lol). 720p is fine but since it does do 1080p why not use it. I have to say 4 GB could be tight for a long movie even at 720p, imagine doing LOTR at 720p? Honestly it's probaly going to be great for TV shows or really short movies. As for why I would want 720p or 1080p on this thing? It's so I can watch it on my big screen or at my friends big screen. Would be pointless to view it on the built in screen as it's only 800x480

If recording HD video on the Droid X... copying the file or transferring the file over to your computer... does that actually keep the file real HD?
I heard of a few other "HD" phones or flip-like devices that did not keep the HD when moving the files outside of the actual device.
Let me know what you all know.
(Still waiting for my Droid X to ship to me)
Yes, Export is 1280x720 wit frame rate of 23fps.
Audio is 96kbps/44hKz mono
Thank you.
You think they will allow or stereo audio with the device having 3 mics?
What about when you hook it up to a HD Tv? I was thinking about putting movies on the memory card and then watching it directly on the Tv... Will it work/look like HD?
Yup - the files are output over HDMI in 720P HD resolution. (It supports several resolutions) From what I've tried so far, you'll get the best results with MP4 videos encoded with .H264, with a resolution of 1280x720. (or close to that) I'm not sure what the bitrate is, but the files I encoded with handbrake are about 1 GB per hour of video. They look great on the phone and on widescreen TVs.
Note:
I also tried the HDMI output on a older 4:3 computer monitor over DVI (using a HDMI to DVI adapter). It does work - however, to match the video to the 4:3 aspect ratio, it lowers the resolution and puts black bars on the top and bottom. On a 16:9 TV or monitor, this does not happen.
Thank you... exactly what I wanted to know.
How powerful is the Adam's video out. If I have an 8gb .mkv in 1080p, will the Adam be able to play it smoothly on a 50 inch TV? How about if that same file is playing from an external USB hard drive connected by USB.
Some of these factors don't count(File size, tv size).
If adam supports 1080p output any hd tv with the right connection (hdmi) will work. As for mkv it depends, mkv is just a container, depends on the codecs used for audio, video; anyway, the hardware is capable of outputting hd video, most other variables are in the software, and if the delivered software isn't enough, we will always hack it.
I love my Archos 70 IT, and I'm really impressed by the great multimedia players Archos included. I've been using the video function to browse my local network for SMB shares - I have a 1.5TB NAS storage appliance loaded with TV shows, music and movies. I open the NAS over SMB and can stream videos great. However, a lot of my library is in 720p quality. These files play fine for about 1 minute, then get very choppy.
I haven't yet attempted to copy a 720p video to the Archos locally to see if it will play smoothly. I suspect it will, since it plays just fine for a minute or more in most cases. I think the network buffer is running low. If I pause the video for 5 seconds then resume, it plays smoothly for a few more seconds before getting choppy again. But pausing it for longer doesn't seem to help any more.
I don't see any options in the app to change the buffer length or anything like that. Does anyone have a suggestion on how I can improve hi-res network video playback?
Note: I'm using an 802.11g wireless network with the Archos about 5 feet from the WAP. No signal strength issues.
Even with a regular PC or laptop, it's kind of iffy for me to stream 720P consistently. While in theory, a WiFi G connection is supposed to be 54 Mbps, in reality, it's often a lot lower due to interference from other WiFi radios. Where I live there are a dozen WiFi radios that show up when I do a scan. What's amazing is that one or two of them are stronger than my wireless router a few feet away. Who are these people?!
Bye.
Ha, thanks for the response. I can definitely stream 720p to my laptop successfully. The radio in the Archos might not be able to keep up though. Dunno. In any case, some sort of buffer options would help!

The fact that it plays ok at first, then gets choppy indicates that you're playing through the contents of the buffer faster than it can be replenished by the network stream. A bigger buffer would make it play longer, but it would still run out. Picture a bucket with a hole in it. If you don't fill it faster than it drains out the hole, it will eventually be empty, no matter how big the bucket. Pausing is like putting your finger in the hole. It lets it refill, but it can only get so full. Pull out you finger and it starts draining again. The only solution is a bigger hose or a smaller hole
I too get the choppiness when streaming via smb. But I have put a 6gb 720p movie on my A70S, and it too gets choppy. This was with 2.1.4. AND with the newer 2.1.8. so then I fully restored the device to increase the swap file, and it's not any better. Now im rooted using archangel, and used setcpu to keep the cpu maxed, but not any better than it was.
btw, i used the archos video splitter app to get such a big file on there.
Even 1.5gb 720p cartoons act up, i get the video falling behind when there is alot of motion. I'm hopeful it will get better!

Did you put the movie on your SD card? How fast is your SD card? Try moving it to internal memory and playing it from there.
Yes, i forgot to mention that. I tried it first on the SD card, still crap. Put it on the internal memory, still just as bad. I did think that doing so would fix it, but, no dice. unfortunately.
Of course you should be able to play a 720P video from inside your Archos cleanly. By any chance is the video encoded at a high bit rate, like maybe 10 Mbps? I have a bunch of videos I can play fine on mine, however, I encoded them at maybe 2 - 4 Mbps. The specs for your Archos says:
Video Playback1 • MPEG-42 HD (up to 720p, 30 [email protected])
• MPEG-42 ([email protected] AVI, up to DVD resolution, 30 [email protected])
• H.264 HD ([email protected] up to 720p, 30 [email protected])
• WMV9/VC1 (AP up to 720p 30 [email protected])
• M-JPEG (Motion JPEG Video) in VGA resolution
With optional plug-in (downloadable on www.archos.com):
• Cinema: MPEG-2 (up to DVD resolution MP/D1, 30 [email protected] Mbps)
With the above codecs, the device can play video files with the following extensions: AVI, MP4, MKV, MOV, WMV, MPG, PS, TS, VOB, FLV, RM, RMVB, ASF, 3GP
Are you well within these requirements? A PC or laptop can usually go way past this.
Bye.
One of the files is 720p avc1 dts at 6425 Mbps, and 4.38 gb. I'll have to check the other files when I get home. But that's not too high quality is it?
No, but if these are Animes the chance is high that they are encoded with "to many" b-frames.
The Archos allows [email protected] most new HD Animes are encoded as [email protected] which has way to many B-Frames for the small buffer on the DSP.
I think you are pushing it on the bit rate. I have tried encoding at various bit rates and quite frankly, encoding at 2 Mbps is good enough visually on an A101. I suggest Handbrake to re-encode down to 2 - 4 Mbps.
Bye.

Yes yes, I did. BUT...
And wasn't the new firmware supposed to make these higher profile files play better??
wish in one hand....
No.
The decoding of highbitrate files within the specs is better now.
"One of the files is 720p avc1 dts at 6425 Mbps, and 4.38 gb."
avc1 == H.264 and if you look into the specs, there it says -> H.264 HD ([email protected] up to 720p, 30 [email protected])
So you are allready above what the DSP ( the VideoCoProcessor in the Chip ) can handle.
And then normally these type of files have variable bitrate and can go up to 20MBit.
And if then these files have more then the allowed 5 B-Frames the dsp just pukes.
So did anything ever come of this?
I'm having the same issue with the latest firmware (2.3.20).
Being able to increase the buffer and waiting a few minutes before watching something would be a whole lot better than copying the entire thing or just sticking to SD.
Hi all,
Is anyone else experiencing stutter on their NP no matter where you play videos. Local memory or over network, for me is the same. I tried with 1080p and 720p and both stutter like crazy, upon to an unwatchable point for high bitrate mkvs.
I reflashed 511 via fastboot erasing userdata but no luck, same annoying stutter.
Any idea/suggestion is appreciated.
Thank you
I tried playing MKVs over network with Kodi, but they stutter incredibly bad. I don't think the support for MKV is there, but I could be wrong. Sticking with MP4 for now.
The OP doesn't provide any info about setup or apps tested.
But FWIW, all MKVs that I've tried - 720p, 1080p, inc. 10-bit encodes - have worked flawlessly on Kodi, whether locally or over network (smb or DLNA, WiFi AC/5Ghz).
So you need to isolate your problem to your setup. You could start by enabling the Codec Info OSD in Kodi ('c' key on a keyboard, can be remapped to e.g. remote back button) to see what's happening with your currently playing videos.
You could play with the hardware decoder settings in Kodi's System config to see if toggling any of the options might help. Also try different apps, of course. There are lots of possible variables really ... isolating the problem is the key.
I have not had issues with playing 720p or 1080p H264 / x264 MKV files with Kodi over 5 GHz wireless AC. I usually go through an SMB server to stream the files from another PC on my LAN or the USB drive plugged in to my router. Which video codecs are your files encoded in and how high are the average bitrates of those files?
It would be good to know if OP is using Kodi or a different player..
Hi All, sorry for the delay, I think I managed to track the cause of my stutter. First of all, to answer your question, it is happening with all players, including Kodi.
After some more testing, I came to the conclusion that it is related to the framerate output that is not in sync with my TV refresh rate. I have a Samsung that goes to 60Hz max, and video sources at 24fps stutter/judder like hell. I cannot watch any 24fps movies no matter their format. I tested with 60fps content and all was playing fine.
Really not sure why AndroidTV/Nexus Player does not allow automatic framerate switching, but watching anything at 24fps is basically impossible for me. TVHZ app allows me to go to 50 or 60 Hz, but I read this bug is fixed in M dev preview. Did not tried it yet.
Kodi is supposed to be able to auto switch framerate, at least in one of their build (for Shield if I recall correctly), but even if I have the option enabled in the menu, video playback is still stuck at 60Hz.
Does anyone know if auto framerate switching is going to be added in 6.0 ?
Thank you
Well, there's nothing unusual about playing 24fps sources on a 60Hz TV, and you shouldn't be seeing such severe juddering even with 3:2. This forum would be full of complaints otherwise, since 24fps sources are so common.
Are you able to test with another TV than your Samsung, perhaps? And enable the Codec Info OSD in Kodi to see if that reveals anything. I'd also try toggling the "Sync playback to display" option in System settings. For comparison: http://forum.kodi.tv/showthread.php?tid=219796

What about other players? Kodi made this possible via their internal player, not Android's as far as I know.
@Ladduro, I'm not sure what you mean by Android's "internal" video player or if there even is such a thing on the Nexus Player. If other popular apps like MX Player and VLC support auto frame rate switching in the future, then you'll have more playback options beyond Kodi.
I've been playing plenty of 24fps sources on my 60Hz TV without the pulldown causing an unwatchable judder as decribed by the OP. I still think he's misdiagnosing the problem, but I guess once an idea gets in your head it's hard to shift it.
Maybe you cannot see the judder. I can, and it is bothering me a lot.
Is there no way to activate the "Sync playback to display" option for the NP? A different Kernel maybe?

Mine has always stuttered. I have never found a solution. I watched a google play movie just last weekend and I noticed it. My wife and kids don't notice it but I sure do. I've tried wired and wireless connections and it doesn't make a difference. And I don't have barebone internet speeds. Debating RMAing it since it is from an early batch to see if the newer ones work better.
Hello guys. Yesterday I got my Nvidia Shield TV 16GB from Amazon and I tried to configure and play some online TVs and videos. The problem is that the picture is not as smooth as it was with my previous Android box - I think it is connected with the resolution and change of the refresh rate when playing the channels. My TV is Panasonic ST50. In the settings menu of the Shield I have set the resolution to 1080p at 60 Hz. I have tried to play some videos in Kodi too (I have activated the option Adjust display refresh rate). With these settings when starting a video or a channel the refresh rate switches to 50 Hz but the picture is not smooth, with judder, with obvious problems when watching sports.
Any ideas how to solve the problem?
Is the video your are testign with 50hz? DO you know your tv can handle a 50hz?
what happens when you play a 24hz or 60hz file? (BR)
My tv does 324, 30, 50, and 60. If I feed it a 50hz video it forxes the tv to 60. Its not jittery, but does look slightly odd.
Try playing it in Kodi, without the adjust framerate setting, and see how it plays.
ARe you feeding the hdmi via a audio receiver?

I am testing with 25Hz and 50 Hz video. My TV can handle 50 Hz. I have a proof that the TV is fine - I have Minix Android box too and everything is perfect when playing the same videos with the Minix on my TV.
I have tried both options - on and of, for the adjust framerate setting - no difference in the result.
I don't use audio receiver.
I fell I have tested everything and still the problem is there.

Thank you! I saw a thread in the Nvidia Shield Forum about users experiencing problems with deinterlacing, so maybe I am just one of those users. Obviously I will have to wait for another update or reaction from Nvidia
Hi,
I used to have this jitter problem with firmware 3.2. I had jitters on all video players except Kodi. And also on game stream.
I fixed the video jitters by downgrading the firmware to 3.1. But unfortunately the game stream jitters still there.
You can try to downgrade. But you need to unlock bootloader which will break your warranty.

Thank you, zizicici. Downgrading will be my final solution if not else helps. For now, I don't want to break the warranty of the device. But if there is no other solution (or no update from Nvidia soon) probably I will proceed.
