@Mosu,
all the MKV muxers remove the AUDs (00 00 01 09 xx) when muxing h264 streams to MKV. That's alright, of course. But that means if we mux a raw h264 stream to MKV and then demux it again, we lose bit perfectness. Which is quite ugly.
So here comes my feature wish: Could you please readd AUDs into the stream when demuxing h264 streams with mkvextract? I think/hope it shouldn't be difficult to do.
Thank you...
