I got an issue with ffmpegthumbnailer, used following command to generate thumbnails from new.mp4.
ffmpegthumbnailer -i new.mp4 -o tmpfile1.jpg -c jpg -q 10 -s 600
Got following error and failed to generate thumbnail.
Not a native file, thumbnailing will likely fail
Segmentation fault (core dumped)
I tried to create another version using same command except size attribute( -s 640 instead of -s 600).
ffmpegthumbnailer -i new.mp4 -o tmpfile1.jpg -c jpg -q 10 -s 640
thumbnail successfully generated.
I don't know why thumbnail of version-600 not getting generated.
