Video on Demand - Quicktime, transcoding, and mux (mux_name)

Postby thaimin » 11 Oct 2008 04:25

Hi,

I have been trying to setup VOD so that it will stream in a format that non-VLC players can understand. Currently it will work with Quicktime with no transcoding for some files that Quicktime can stream normally. Does anyone know the exact set of video codec / audio codec / mux to use to allow Quicktime (and hopefully also Media Player Classic) to be able to read both the video and audio streams? I would prefer MPEG-4 if possible. Also, is there any chance of getting it to work with Window Media Player?

Another problem I am running into is I can only mux to TS and PS and nothing else because the VOD parameter "mux" requires a "four character length identifier such as mp2t for MPEG TS or mp2p for MPEG PS". It should be able to mux to PS, TS, Ogg, ASF, MP4, MOV, etc, right? What are the four letter codes for these? I cannot find four letter codes listed anywhere, except the two example ones. The normal mux values (like asf, mov, etc) do not seem to work...

I do not seem to be able to send a mpeg4 stream at all through VOD, even to VLC ("Unsupported transport" error messages in message box when trying #transcode{vcodec=mp4v,...,acodec=mp4a,...} with or without a mux mp2t).

Maybe I am just going about this all wrong though. Is MPEG4 not a good choice for this? Can you only mux to PS and TS for VOD? Will I just not be able to stream some files in Quicktime and no files ever in Media Player Classic and Windows Media Player?

Thanks,
Jeff
