>2. The input file used mpeg2video and AC-3, but the following commands
While trying to cut down a 3h/12GB video to something more manageable
(say, 1GB), I tried again with the same result :-/
Container : MPEG-PS
Duration: 03:02:14.36, start: 0.226767, bitrate: 9463 kb/s
Stream #0:0[0x80]: Audio: ac3, 48000 Hz, 5.1(side), s16, 448 kb/s
Stream #0:1[0x1e0]: Video: mpeg2video (Main), yuv420p, 720x576 [SAR
64:45 DAR 16:9], 25 fps, 25 tbr, 90k tbn, 50 tbc
To extract a sample, I ran the following...
ffmpeg -i input.mpg -ss 0 -t 30 -c:v copy -c:a copy output.sample.mpg
... but it still can't play in VLC: There's video but no sound. I
don't know if it means anything but Tools > Code Information shows...
24 streams (1 video, 11 subtitles, 13 audio).
In case someone wants to take a look, it can be downloaded here:
