Laurent <[email protected]> added the comment: So, r21621 hides something else. I performed another dichotomy with r12684 reverted.
r20667 reveals the issue in this case: Start decoding from seq/gop too, not just I frames. Possibly fixes issue1124. When the decoder delivers a non-key frame (seq/gop), FFmpeg encodes it anyway, resulting in a grey frame. All that looks ok (if I get it right). What still seems an issue, is that -ss (av_seek_frame) is supposed to seek to a keyframe... so the first frame out of the decoder should be a keyframe anyway. Or I am misunderstanding something here? Thanks. ________________________________________________ FFmpeg issue tracker <[email protected]> <https://roundup.ffmpeg.org/issue2019> ________________________________________________
