Fix thumbnail extraction of mpegts videos in FFmpeg 7.1+

Issues

The mpegts demuxer cannot seek to keyframes, so we have to let the decoder discard non-keyframes, which may contain corrupted images. The problem is more noticeable in FFmpeg 7.1+, before that only a small number of samples were affected.
