Decoding quality is very poor in some situation.

[tyan0]

For example, decoding original.mp4 by libopenh264 and encoding again by libx264 results in:

decoded-by-openh264.mp4

while decoding the same video by h264 decoder in ffmpeg and encoding again by libx264 results in:

decoded-by-ffmpeg-h264.mp4

Is any important feature of h264 missing from openh264?

Yes. The pull request #3707 fixes only the reordering of the decoded frames. I guess this issue is in the decoding algorithm.
