Andrew, ok thank you. It does not look like ffmpeg 4.4 is going to make it in this month.

I am going to create new AppImages tomorrow because of the gang bug which is too serious and has no workaround.

also added two old (1996/8) h263 codecs - it theory they should be good for low-cpu decoding (on emulated computers for example), but apparently h263 without 'p' only good at few pre-defined resolutions?

Did not even know h263 existed. I will test today since it is something I can actually do!

sorry for not making progress on more important issues - I fiddled around with overlayframe.h - but I can't see my addons working? Either bug in code or I translated those blend modes wrongly..

No problem, everyone should just work on what is fun and interesting for them. This bug has workarounds

that are usable but tedious so we will have to tolerate that and it has existed for a long time.

there also two ffmpeg-4.4 patches recently added to git - they apply with patch -p1 yet not with git apply patch (misformatted patch).. Adds avc intra 300/480 if compiled against last x264 (15 june 2021)

For some reason, I did not make the connection that the new x264 required ffmpeg 4.4 and I tried to upgrade

to it yesterday. But IMPORTANT QUESTION, the "stable" version, which is what we have always used in the past

is dated around June 13th. Would it not be better to continue that policy instead of using June 15? See

attached and note the box in upper left hand corner saying "stable".
