Description

I get an bus error while converting 474 images á 32kb with the following cmd-line:

ffmpeg -f image2 -i *.jpg ./a.mp4

Result:

Any ideas what's causing this error and how to get around it? Google wasn't much of a help. I'll attach a sample jpg file.

  • Component changed from FFmpeg to undetermined
  • Status changed from new to open
  • Version changed from unspecified to git-master

To produce a useful back-trace, please use ffmpeg_g instead of ffmpeg, as explained on http://ffmpeg.org/bugreports.html

  • Component changed from undetermined to FFmpeg
  • Priority changed from normal to minor
  • Reproduced by developer set
  • Summary changed from Bus error while converting images into a movie to ffmpeg.c crashes for more than 100 output streams

The correct syntax for your use-case is

ffmpeg -i img%03d.jpg a.mp4
