Description

Summary of the bug:
I'm trying to encode video encoded from dv in avi container to x264 in mp4 container but got error... (please see output below)

If I decreasing start time of input stream from 00:52:37.640 to 00:42:37.640 or lower it start converting.. I have tried to move "-ss" to the end(before output argument) it will shown no errors but it taked to much time for transcoding...

How to reproduce:

/usr/bin/ffmpeg -y -v 9 -loglevel 99 \
-ss 00:52:37.640 -t 367 \
-i "/tmp/converter/2012-05-29-W16/input_file.avi" \
-pass 1 \
-passlogfile "/tmp/converter/2012-05-29-W16/input_file/out_input_file.log" \
-vcodec libx264 \
-x264opts level=3.1:threads=auto \
-vf "yadif,format=yuv420p,scale=iw*sar:ih,fade=in:0:25,fade=out:9150:25,crop=736:560:16:8,setsar=1:1,setdar=736:560" \
-preset slow \
-b:v 1700k \
-an \
-f mp4 \
-threads 0 \
/dev/null

Output:

It is looks like similar to http://ffmpeg.org/trac/ffmpeg/ticket/1235

comment:2 follow-up: Changed 4 years ago by cehoyos

  • Component changed from undetermined to avcodec
  • Keywords start time ffio removed
  • Version changed from unspecified to git-master

Is the problem also reproducible with "ffmpeg -ss 00:52:37.640 -i /tmp/converter/2012-05-29-W16/input_file.avi -qscale 2 out.avi"?

Could you provide the output of "ffmpeg -i /tmp/converter/2012-05-29-W16/input_file.avi -f null -" (how long is the input sample)?

Replying to cehoyos:

Yep, it is reproducible:

hmm.... I guess problem in source file, am I right?

  • Component changed from avcodec to undetermined

FFmpeg says the source file is 49 minutes long which makes seeking to 52 minutes impossible.
Is the file actually longer?

Yes, it is. You can see output of ffmpeg and ffprobe. Both show correct duration:
Duration: 01:37:44.72

Guys, thank you every one for your help!
I'm really sorry!
Issue was with broken source video file.. My bad - I excluded file consistent check based on some info which I sured in. But it was wrong info...

..so ffmpeg/ffprobe got duration info from header/container info... Right?

I am closing the ticket, if I misunderstand, please reopen.

Cut the file radically with dd to find out.
