Description
Summary of the bug:
It looks like the duration is incorrect if cache protocol is used. (cache 00:00:03.71 vs file 00:02:25.68 )
How to reproduce:
$ ffprobe "file:///Users/xxxx/Downloads/Videos/Hellboy.ts" [mpeg2video @ 0x7fc6e9015600] 0x0 is invalid Last message repeated 29 times [mpegts @ 0x7fc6e900d000] PES packet size mismatch Input #0, mpegts, from 'file:///Users/xxxx/Downloads/Videos/Hellboy.ts': Duration: 00:02:25.68, start: 41174.341300, bitrate: 10882 kb/s Program 1 Stream #0:0[0x10]: Video: mpeg2video (Main) ([2][0][0][0] / 0x0002), yuv420p, 1920x1080 [SAR 1:1 DAR 16:9], 29.42 fps, 59.94 tbr, 90k tbn, 59.94 tbc Stream #0:1[0x11](eng): Audio: ac3 ([129][0][0][0] / 0x0081), 48000 Hz, stereo, fltp, 384 kb/s $ cat ~/Downloads/Videos/Hellboy.ts | ffprobe "cache:pipe:0" [mpeg2video @ 0x7fd4f9815600] 0x0 is invalid Last message repeated 29 times Input #0, mpegts, from 'cache:pipe:0': Duration: 00:00:03.71, start: 41174.341300, bitrate: 11763 kb/s Program 1 Stream #0:0[0x10]: Video: mpeg2video (Main) ([2][0][0][0] / 0x0002), yuv420p, 1920x1080 [SAR 1:1 DAR 16:9], 29.42 fps, 59.94 tbr, 90k tbn, 59.94 tbc Stream #0:1[0x11](eng): Audio: ac3 ([129][0][0][0] / 0x0081), 48000 Hz, stereo, fltp, 384 kb/s

Yes, it's reproducible on both ffprobe and ffmpeg
comment:3 Changed 8 years ago by cehoyos
Then please provide the failing ffmpeg command line together with the complete, uncut console output (only report problems against ffprobe if they are not reproducible with ffmpeg).

Is this only reproducible with ffprobe of also with ffmpeg -i ?
