Description

Summary of the suggestion: Could you make a tool to oscillate a sequence?
This is how I now oscillate:
ffmpeg.exe -r 30 -start_number 2 -i numbers.%%04d.tif -frames 33 -vcodec qtrle forward1.mov
ffmpeg.exe -r 30 -i numbers.%%04d.tif -vcodec qtrle -vf trim=end=1.1666666,reverse reverse1.mov
ffmpeg -i forward1.mov -i reverse1.mov -filter_complex concat=n=2:v=1 -vcodec mjpeg -q:v 7 -f mov oscilate.mov

In addition, it would be great if the reverse tool could have start and end frame numbers.

ffmpeg version N-78598-g98a0053
built on gcc 5.3.0  windows

Patches should be submitted to the ffmpeg-devel mailing list and not this bug tracker.

  • Component changed from undetermined to avfilter

Cant you use single ffmpeg command to do same?

doable with loop and reverse filter.
