i'm trying to mux a mpg file use the following cmd
ffmpeg -y -i 1.m2v -i 1.mp2 -c copy -f svcd 1.mpg
it finished muxing without any errors & warnings.
of cause, the original mpg file is normal.
but the muxed mpg file is not normal, it can be played on PC with codecs
but not in most DVD players.
the following bugs i found:
1. audio always has a Delay relative to video such as "-67ms"
2. the mux rate is too big.. i think it should divided by 8.
3. i think the PCR is also buged, it's not begin with 0, the SCR base is
not begin with 0, either.
it's hard to read the mpegenc.c for me,
i think developers can fix it well.
sorry for my bad eng.
