Great! We're nearly there. Now I'm running something like
>cat mux2.share.ts | dvbstream/dvbstream/dvbstream -stdin -ps
-o:out.mpeg 2061 2071
but the "-ps" option isn't working - I'm still getting a transport
stream out. Here's
the output from running ffmpeg on the output:
Input #0, mpegts, from 'out.mpeg':
Duration: 00:01:19.53, start: 16667.481133, bitrate: 3898 kb/s
Program 82
Program 2000
Program 2005
Stream #0.0[0x7ef]: Data: 0x0006
Stream #0.1[0x80d]: Video: h264, yuv420p, 704x576 [PAR 16:11 DAR
16:9], 25 tbr, 90k tbn, 50 tbc
Stream #0.2[0x817](dan): Data: 0x0011

Stream #0.4[0x826](dan): Subtitle: dvbsub
Program 2010
Program 2025
Program 2030
so it's apparently picking up all the other datastreams associated with
the same program as the actual pids I asked for.
(Btw, sorry if we're drifting off topic for mplayer-users.)
cheers,
Colin
