MP4 Video streaming with AAC audio

[gwaitsi]

Note sure if i will find the answer here but it is worth a try.

I have been struggling for near on a year to get this working properly. I am trying to stream MP4 to my PS3 over a wireless network of relatively short distance between devices.

- for streaming i have tried both TVersity and Nero Media with same results.

- for mp4 creation i have tried a number of things x264 (with/without) PS3 profile, Nero Recode, etc

for testing i have tried various combinations
- MP4 video (h264) only - OK
- MP4 video (DivX) only - OK
- AAC (2 / 5.1) audio only - OK
- AVI (DivX/MP3) - OK

The problem is when combining the h264 + AAC (2 or 5.1). When streaming, the video/audio jumps i.e. starts/stops every few seconds.

If i copy the file down to the local hdd and play there is no problem.

I tried muxing with Yamb and MP4Creator and MP4creator files don't stream at all - show corrupt data on PS3 although they play in other players.

the wireless is good. i setup QoS and it plays AVI or any of the examples above fine. So it is definately something specific with the streaming of h264+AAC.

Grateful for any ideas.

FYI - I found a way for to have streaming working perfectly over wireless.

Using Nero Media and transcoding the video to MPEG-2 and the audio to LPCM, streaming works like a charm over wireless.

Problem with this solution, you loose the 5.1 audio.

I tried to transcode just the audio with Nero but AAC 5.1 is still output if the video is MP4 AVC.

In conclusion, i am now certain there is not a network issue. The issue is definately to do with the AAC and the PS3 in specifically.

Other PCs running various players i.e. can stream the AAC 5.1 no problem. So certainly has to be something with the PS3.

Maybe this is not the right forum, given it is not an audio forum, but this only happens with the nero aac 5.1/2 is muxed with video.

My nero aac music albums with chapters and covers stream perfectly to the PS3 as well (although without the chapter and cover info)

Sorry for my English.:rolleyes:
You are reconverting video, aren't you?:eek: But there is another container, which perfectly streams!:cool:
Try this:
1. Demux a h264 stream from a *.mp4 container (YAMB or MP4 Multiplexer/Demultiplexer)
2. Get a surround sound from the source or reconvert AAC 5.1 surround to AC3 (for reconvert - FAAD and Wav to AC3 Encoder)
3. Mux resulted streams to *.m2ts container. (tsMuxeR will save the day :)) How to do? Look here

4. Stream it with TVersity!!!

hi Oleg

You are correct.

streaming m2ts with AC3 packaged this way does work.
However, defeats the point of moving the audio to AAC in the first place.

But thanks, it does prove that the network (even wireless) is fine and given that PC software players have no problems with the AVC+AAC then, the problem seems to be on the PS3 side, particularly given it does stream AAC audio no problems.

I am suprised no one has come up with a solution todate.
