This issue is also related to the following defect: " https://ffmpeg.org/trac/ffmpeg/ticket/1026". However, I believe, some code still need to be implemented in ffmpeg to fix this issue.

This looks like a duplicate of #1026 to, which has been fixed.
If this is still reproducible with latest git please reopen.
