Hi Jan, all
I am trying to generate a video introduction with a fade-in / fade-out
effect. To do this with ffmpeg2theora only, I generated a list of PNG
images: img001.png, img002.png... img299.png
The ffmpeg2theora man page says:
Encode a series of images:
ffmpeg2theora frame%06d.png -o output.ogv
That's exactly what I tried with the latest 0.24 release of ffmpeg2theora:
ffmpeg2theora-0.24.linux32.bin img-%03d.png -o output.ogv
Input #0, image2, from 'img-%03d.png':
Duration: 00:00:12.00, start: 0.000000, bitrate: N/A
Stream #0.0: Video: png, yuv420p, 1280x720, 25 tbr, 25 tbn, 25 tbc
Resize: 1280x720
Segmentation fault
The same problem happens with the release in Ubuntu 9.04, and with the
0.22 release. I haven't tried earlier releases yet.
To reproduce this issue, you can get the images from the tarball on
http://free-electrons.com/issues/ffmpeg2theora-jul15-2009/
I would like to avoid using mencoder + ffmpeg2theora to do the job
(unless I manage to generate the theora video directly from mencoder).
I hope this helps to fix this issue... Don't hesitate to get back to me
if you have any question.
Cheers,
Michael.
