Random audio PID order

Postby Antarius » 08 Oct 2010 22:32

Every time vlc is started for streaming, order of audio tracks is random. I need to make it static.

For example pids video 328, audio 428,429

Only way I found is "#duplicate{dst=http{mux=ts,dst=ADDRESS:PORT},select="es=338,es=428,es=429"}"

But it doesn't work, only video is streamed, no audio. Looks like second and third es are ignored. Is there any way to do this right?

I found several same questions about this, but with no answer. Is it really impossible to do such a simple thing?

Hi Antarius,

I have the exact same requirement.

Do you get a resolution to your problem?

I've this problem twice. I don't know if anyone has ever dealt with this afterwords, or if eventually found a fix for it.

I had to deal with /src/input/decoder.c and synchronize the audio threads (refer to function DecoderThread()).

A quick and dirty hack using static variables will do the trick. All audios enter DecoderThread sequencially, but they are decodec asynchronously due to the multithreading. Just make sure they are decoded synchronously and that's it.
