OK... it seems to be dependent on the audio sample rate. It works with 48000
bps with either 23.976 or 29.97 frames per second, and doesn't work with
44100 bps and 29.97 fps. I haven't tested other combinations.
I made a couple of test files. They both worked OK. They were:
$ tcprobe -i test24.mpg
[tcprobe] MPEG program stream (PS)
[tcprobe] summary for test24.mpg, (*) = not default, 0 = not detected
import frame size: -g 720x480 [720x576] (*)
aspect ratio: 4:3 (*)
frame rate: -f 29.970 [25.000] frc=4 (*)
PTS=0.8477, frame_time=33 ms, bitrate=1800 kbps
audio track: -a 0 [0] -e 48000,16,2 [48000,16,2] -n 0x50 [0x2000] (*)
PTS=0.8477, bitrate=128 kbps
-D 0 --av_fine_ms 0 (frames & ms) [0] [0]
$ tcprobe -i test30.mpg
[tcprobe] MPEG program stream (PS)
[tcprobe] summary for test30.mpg, (*) = not default, 0 = not detected
import frame size: -g 720x480 [720x576] (*)
aspect ratio: 4:3 (*)
frame rate: -f 29.970 [25.000] frc=4 (*)
PTS=0.1780, frame_time=33 ms, bitrate=1800 kbps
audio track: -a 0 [0] -e 48000,16,2 [48000,16,2] -n 0x50 [0x2000] (*)
PTS=0.1780, bitrate=128 kbps
-D 0 --av_fine_ms 0 (frames & ms) [0] [0]
The one I reported above that stopped at 83.4% had a 44100 bps audio track:
import frame size: -g 352x240 [720x576] (*)
aspect ratio: 4:3 (*)
frame rate: -f 29.970 [25.000] frc=4 (*)
PTS=14292.9438, frame_time=33 ms, bitrate=1152 kbps
audio track: -a 0 [0] -e 44100,16,2 [48000,16,2] -n 0x50 [0x2000] (*)
bitrate=224 kbps
