Hi everybody, since the following commit https://git.videolan.org/?p=ffmpeg.git;a=commit;h=8ed82d8174a666f80ab8834e3617cbe91ae740a9 mxfenc is only writing one value for progressive content. Unfortunately the commit comes without any explanation at all.
SMPTE S377-1-2009c (the version I have) defines in F.4.1 that the field
is always 8 + 8 bytes. That is, 4 bytes number of values, 4 bytes value
size. And then 2 32 bit integers with the actual values.
G.2.12 then clarifies that even more and says that for FULL_FRAME frame
layout it would always be {first line number, 0}. Example given there
720p would be {26, 0}.
Unless a later version of the standard somehow changes something there,
I would say that this commit should be reverted.
Best regards,
Sebastian
