Re: No Audio with VLC Encoder on PS3

I did some testing too.

I reproduced the AC3 issue you describe and went a little further in understanding why the mp2 is not played.

According to the VLC streaming features page:
https://www.videolan.org/streaming-features.html

the PS output doesn't support anything else then AC3. Which means mp2 and aac are NOT supported using PS.

Following this hint I changed the code to use mp2a and TS as output method.
My video played perfectly.

I don't know if this can break things on other platforms but it surely works for me.

Now that I started to dirt my hands on the code I'll test with other video formats too ;)

Oh, I noticed another issue

If you do not override the sample rate it may give 0 as sample rate provoking a very weird effect with AC3 audio

Read it again :-) (or see here).

You don't need to change the code to do that: PS3.conf -> TranscodeVideo -> MPEGTSAC3.

I don't know if this can break things on other platforms but it surely works for me.


Bear in mind, this is an issue with that video (and, possibly, some similarly-encoded source videos), not with the PS3 and all videos transcoded/remuxed to MPEG-PS/MP2. That combination is supported by all compliant DLNA renderers, including the PS3. Apart from an unrelated issue with MPEG-2-incompatible framerates, that combination works fine for me and presumably everyone else who uses the VLC engine.

My guess is that it's an issue with VLC's HE-AAC decoder, possibly in conjunction with VLC/ffmpeg's GPU acceleration (which is buggy), but it's hard to tell without a sample of the video.
