A frame is what the decoder returns in avcodec_receive_frame().
If that is true, then I cannot see, how to work around that without

Hi,
Subject "new error" is a rather ambiguous title. You really should
make that more specific. How are people supposed to know what this is

Oh
, more than 1000 commits
behind current git master. The bug(s) that may be there could well be
fixed in the meantime. So, please try the latest release and, if the

Since you just mentioned it, how do yoou record the files in question,
