Summary of the bug:
FFMPEG decodes DivX 5.0 interlaced video with awful block artifacts.
I assume DivX generates buggy bitstream (as XviD also decodes with
artifacts), but at least it is decoded correctly by DivX itself.
How to reproduce:
{{{
- Encode any video as interlaced using DivX codec (tested with DivX Pro
5.0.5 + VirtualDub2 44828) with b-frames enabled (this is default for DivX
Pro 5.0.5 encoder) and all other settings left as default.
- Try to decode the result with ffmpeg:
ffplay divx_interlaced_decoding_artifacts.avi
- The resulting video has lot of visible block artifacts, mostly
noticeable on b-frames.
}}}
