It would be great to have a tool that can take any arbitrary MPEG2 file and add those dummy NAV packets.
really, the best way to do this is to demux and remux. This is because you need to ensure that you get the data to the decoder before it needs to be presented. mplex has all that logic built in. I do NOT want to duplicate it in a separate program.
So it'd probably be useful to have a program that automatically scanned an mpeg2 program stream to determine how many different data streams it contains, and then automatically call mplex with the appropriate number of parameters (as fifos), and then forward the data on.
actually mpeg2desc is most of the way there, it just can't handle private streams (aka ac3, dts, pcm, and subtitles).
Therefore, the "right thing" to to would be to add private streams support to mpeg2desc (and mplex) ? How hard is this ? Should any private stream type entail knowledge of it's innards, or does exist some form of "wrapper format" for such private streams, alowing demuxing-remuxing them without interaction with the content ?
If so, how hard would be implementing this ?
