Hello
I installed the cab with Blusoleil stack, set up a PAN network with my PC and tried to stream some videos to my Magician over bt, with Videolan (vlc). I knew that the Magician bt speed was not so good, so i set it the quality far below the theoritical bluetooth bandwidth (~600kbps).
With 300kbps video and 128 audio, the results were horrible... TCPMP player was buffering every 10 seconds.
I tried with every combination of video and audio encoder but i had no luck. With 230 kbps (190 video - 40 audio ) it was buffering about 2-2,5 minutes, but the video quality was not acceptable..
So? Is the module really sooooo slow with the only solution for proper streaming to be the Wi-Fi?

My QTEK S110 can recieve data with 300kbps...
No problem with TCPMP, try another bluetooth-dongle on your PC (at least, bluetooth version 1.2 , 100m).

To be honest the dongle is an old Gigabyte. I bought it before 2-2.5 years, so possibly it's not 1.2.
I'll borrow one from a friend and i'll try again
After searching around about the Imageon coprocessor on the TyTN, I decided to experiment a little. If the TyTN can do .mp4 and .m4a files in hardware, I converted some audio files over to .m4a and see if there was any performance improvement (in Windows Media Player). And there definitely was! General device usage was very quick while playing; I couldn't even notice a difference with or without playing. So, I converted all my music over to .m4a's.
However, the story doesn't end here. My testing was using just the onboard speaker. When I got on the train for my commute to work, I started up my A2DP headset to listen to some tunes. Funny thing, though. They started playing through the onboard speaker! I could hear device sounds through the bluetooth, and if I played an mp3 or a wma, I could hear it through the headset too. But no go on the .m4a/.mp4 over A2DP. No matter what I did, it wouldn't play through anything but the onboard speaker (or wired headset, of course).
Thinking about this, it actually makes sense. If the playback is hardware accelerated, it's probably not designed to go through an A2DP process, which is complete software. The Imageon chip probably passes decoded sound and video directly to the hardware speaker, without going through a software sublayer. I imagine this is by design, as it keeps performance pretty high. MP3's and WMA's are decoded in software without the imageon, so it processes like any other windows sound, and can go through A2DP.
So, there's a bit of a tradeoff here. Do I give up A2DP and all the AVRCP goodness I've come to love at the cost of performance, or do I live with the performance hit of WMAs? Admittedly, audio was ok before, but i've never been happy with the video performance of the TyTN with WMVs. With MP4s, though, it works great. Hmm...decisions, decisions.
Oh, and I've tried TCPMP too. It plays through A2DP, but with the same slowdown. I suspect this is because it doesn't know how to use the Imageon correctly, and is decoding in software too.

Very interesting post and findings. You may find the upcoming Coreplayer 1.0 from the devlopers of TCPMP and Betaplayer of interset to you, as they will be processing everything through software only and claim that they will be releasing the best multi- platform media player ever released: WM, Symbian, Palm etc, XP/Vista Desktop player and Mac Osx. I think you get my meaning. But I for one am looking forward to this as the Imageon 2282 Co-processor is limited in support for various fileformats anyway, and now with your findings, it appears the benefits of it hardware accelerated media cannot be enjoyed over A2DP...man this sucks!!
Anyway, check out this link & hopefully everything will look much brighter in the near future:

Interesting app...I'll definitely be looking forward to it. In the meantime, I found kind of a half-assed solution that works ok for me. I use the wired headset (spliced so I can use real headphones, of course) and I'm using my Itech clip. I pair it up with the Tytn, and AVRCP works within windows media player! So, I get the hardware benefit of the Imageon, and the AVRCP to pause, go forward and backward. Volume even works too! Certainly not the absolute optimum, but it was never the wires that bothered me so much. Works great for me!
Glad u found a workaround. Still, bloody ridiculous that we have to physically adapt things on what is supposed to be cutting edge technology!!

BTW, with an alternate player (if you only need audio), you can have full AVRCP support without cables. (TCPMP isn't compatible with WM5 it seems; some other players are).
I've written a complete article on this at http://forum.xda-developers.com/showthread.php?t=279459 ; it contains a LOT of never-before-published tips and tricks, AVRCP -wise.
Well, doesn't this thread just solve the "Why does WMP play some music out the speaker" question! Thanks, this was very aggravating to me. Most of my music is mp4a (AAC) encoded so I thought that it was a global bug (WMP won't stream music over A2DP). Imagine my surprise when I fired up an mp3 and the damn thing worked
Monday, this might all be moot, however, if CorePlayer actually can do AVRCP. I'm hoping this will be the case since Picard and I exchanged emails on AVRCP back in June. I pointed him to the mortplayer thread and hopefully he did some successful lurking there...
In a way though, CorePlayer will be a bit of a disappointment because their out-of-the-gate solution to the ATI Imageon dhilema will be "no Imageon support". ATI based acceleration is quite impressive when it actually works.
you think ati would bother with coding a player for support, they have the source code after all ,kinda like macromedia with their flash player for ppc, I don't get why they don't benefit from making a player and selling it, instead we're left with 3'rd party players from under developed companies.
Playing with the hardware acceleration has got me thinking, and I'm going to try some experimenting. As you know, mp4 is just a container format, and can house different video/audio codecs. I'm curious as to what exactly has been implemented. LE-AAC seems supported, but I'm going to try to convert some to HE-AAC and see if that has an effect on processor. With video, mpeg4 is probably supported, but what about h.264? I use my TyTN as kind of a PMP, so I'd like to get the best quality I can get out of it.
I'll start some experimenting tonight (watching CPU load on the TyTN) and post my results here!
tcpmp works fine on my universal so is compatable with wm05
Ok, Mpeg4 is definitely hardware accelerated, and h.264 is flat out not supported. A h.264 file encoded as an mp4 wouldn't play in windows media player. The .mp4 files take a while to load up (15-20sec or so), but once they do I could play at full speed, and jump around to any poing within the video with no slowdown. I encoded up to 768k video/128k audio. The higher bitrate I used, the longer it took to load up, but once they were loaded they played flawlessly.
AAC is a little different. If you've read up on types of AAC encoding, there's LE-AAC and HE-AAC. HE is the later standard, and gets better compression at similar bitrates. It's also backward compatible, so LE-AAC players can still play HE-AAC players, but it can't interpret the higher efficiency algorithm and quality is reduced. I can say with some confidence that the player only supports LE-AAC. Both types of files played, but the quality of HE-AAC files (both encoded at the same bitrate) was definitely reduced.
Now, with a proper version of Coreplayer that supports the Imageon, some interesting possibilities open up. The imageon chip does support h.264, and HE-AAC isn't much different either. Once we get version 1.1, or whatever, then we should be able to get the holy grail of Imageon acceleration in most codecs, plus the benefit of bluetooth A2DP streaming. I believe this will make the device much more usable during A2DP, as the only thing the CPU will have to do is A2DP; audio decoding will be left to the Imageon. I hope they can get this to work soon!
I hope I can get the video to forward/rewind/ fullscreen /back without going haywire soon
Hi, I have been looking for a discussions on HE-AAC in this forum for months and finally found yours! To bad though, it is on the Tytn, I am using the good old wizard and HE-AAC is playing well via TCPMP(with the AAC plugin), so well that I converted all my CDs to HE-AAC(in m4a containers).
Just some questions for you:
1) When playing in WMP, are the songs(in LE-AAC) playing in stereo? From what I know and experience, the songs only play in mono in the wizard... So, has the hardware acceleration in the Tytn enable playing in stereo? Cool!!
2) I encode my songs at 16kbps(HE-AAC) though and they are great but all the effort seems to be wasted as I cannot really use A2DP on the wizard as the codecs that I use(be it mp3 or HE-AAC) plays with distortion. The only solution I have now is to use MSI Blueplayer which gives superb quality via bluetooth BUT only MP3s, which I have "happily" dumped a few months ago... sigh...
BTW, is the bta2dp.dll on the Tytn the same files as the used for the Tornado hack?
I've got the tmobile MDA, it plays back AAC+ files great using TCPMP when not using bluetooth, but I recently got my first bluetooth stereo headset and I guess bluetooth must eat alot of cpu b/c AAC+ playback becomes choppy. Has anyone here been able to get smooth AAC+ playback using bluetooth on the HTC Wizard, and if so what did you do to make it happen? I tried another app called gsplayer but that made it even more choppy, and also tried fiddling with the buffer settings in TCPMP but made no difference.
Since I'm a bluetooth newb, I've got a couple more questions while I'm at it. Right now when I want to connect my bluetooth set to the phone I have to:
1) press comms manager button
2) click bluetooth settings
3) go to "devices" tab
4) rightclick my bluetooth headset and click "set as wireless stereo"
Now that's really a pain in ass in my opinion just to connect a headset. Is there an easier way?
BTW, is there a way to make Windows Media Player mobile to playback AAC+ files with the "+" settings? It plays them but sounds like 22 khz, I was wondering if someone has done a hack or something so it recognizes the full "spectrum" of aac+ files.
Sounds more like RFI interference to me.
Is there a wifi network nearby or is the wifi on the phone turned on at the time? Bluetooth uses the same frequency.
Pretty sure It's not an interference problem because it can pipe mp3 music over bluetooth just fine. I know aac is much more cpu intensive to decode compared with mp3. Are you able to listen to aac+ over bluetooth on this 200mhz smartphone?
FYI, there is a wifi network but I have wifi turned off on my phone.
My reason for saying that is that you said it plays back AAC just fine when not on Bluetooth. The other explanation I see being that transmitting data over bluetooth is also CPU intensive and that the two together are too much. But that's just a theory.
No, I've never tried AAC. The few AAC files I've ever gotten I immediately converted to MP3.
But you're right, mp3's play fine over bluetooth. Unless I get too close to my wireless router downstairs, then I get choppiness and skips like you mentioned. However, I do have my wifi signal strength amped up to increase the range.
I managed to solve the problem by overclocking the cpu as described in this thread:
http://forum.xda-developers.com/showthread.php?t=271012
I'm running at 252 mhz now and AAC+ playback is smooth over bluetooth and the system is stable, and feels overall snappier now. But still if anyone knows a solution w/o overclocking I'd like to hear it.

switching to a player requiring less CPU for AAC+ decoding may be of help. If you followed my articles in the General forum, you already knew the answer: most importantly, Pocket Tunes. Kinoma Play may also turn out to be OK, but it consumes more CPU (but still less than TCPMP)
See http://forum.xda-developers.com/showthread.php?t=350786 for more info and, again, do follow my articles.
Not looking to spend the asking price for Pocket Tunes or Kinoma Play, but thanks anyway for the suggestion. In your first post you described mplayer's cpu usage as "17%(!) for HE-AAC" which seems low to me, but you also describe the player as useless. That post was dated from 2005 however, so I was wondering if things have improved in 3 years. And I think I read somewhere that the Windows Media Player mobile for WM6 has AAC+ support- is that true? I'm reasonably satisfied with TCPMP except that I can't use use the media control buttons on my bluetooth phones to control it, so I'm keeping an eye out for something better (preferably free, but I'd be willing to shell out $10 to $20 on a good app)
So for the life of me I can't get any converted videos (converted to MP4) to have video and audio sync'd. I've tried half a dozen diff programs. But what I found out today is that when I play back the audio via the bluetooth adapter in my car, the audio and video is sync'd. What's up with that?
I've searched the forum and it looks like some folks have audio/video sync issues and some don't.
Does anyone know if there's a solution or workaround to get the audio/video synced for MP4 video?
Hey same problem here.
I just used Videora Converter and went to edit the profile in the Video>General tab 2 and set the Audio delay to -0.4 (My audio was faster than my video)
And it's playing in sync in my x10 now Although in my computer, it's now out of sync.
Spent almost 5 hours trying to figure out the problem, but just setting the audio delay was good enough for me.
Hopefully SE can fix this problem. I'm with the firmware R1FB001. Generic NCB
I use headphones or a Sound-freq speaker when watching movies and videos.When using BS player the video and sound do not sync up.If using the gallery player everything syncs up well on both headphones and speakers..Is there a way to sync up the bs player as well?It handles more formats and I like the extra volume and brightness controls on it. thanks

i don't know what BS player is, but this is a common issues across multiple applications. it has to do with BT hardware, the application, BT priority and sound quality.
I have watched several streaming video types using my Potato Tunelink BT adapter. Netflix is by far the worst offender. Off by an entire half-second. Hulu streams great, YouTube has a slight delay. Crackle is about a split off.
If you want quality audio, use the audio port.
BTW, this is true of ANY device. My DROID3/4 both exhibited the same qualities. I thought it was a limitation of the phone. Faster devices do decrease latency, but if the latency exists, it's built into the application.
Maybe I could have been more clear on what I was asking. sorry
I know the problem is there but the BSplayer can be adjusted for audio offset to compensate for the lag.I just can't seem to find out how to do so.The gallery player seems to do it automatically because it always works whether playing files on the device or streaming from my computer or elsewhere. I would like someone to tell me how to adjust this in the BSplayer app. thanks
