I am wondering if the news and enhancements of importance to CinGG/FFmpeg 6.1 users may be outlined, including what is ready now and expected upcoming next?
Something listed last month by Andrew in "ffmpeg 6.1 is out!" and by Phyllis in "GIT... CinGG changes >.FFmpeg 6.1 upgrade from 5.1. ." as the News November 10th, 2023, FFmpeg 6.1 "Heaviside" http://ffmpeg.org/index.html#news
-------
For example while the AV1 codec was mentioned available for CinGG already in February News 2019 https://www.cinelerra-gg.org/news-updates/february-news-for-release-av1-and-...
AV1 looks to be an even more important improvement with FFmpeg 6.0 and 6.1, according to some selected articles below:
FFmpeg 6.0 Will Be Big With AV1 Hardware Decoding, Many Other Features https://www.phoronix.com/news/FFmpeg-6.0-FOSDEM-2023

for this part you need hardware de/encoding support in GPU - so recent AMD or Intel. recent libva. For AMD also new mesa, most likely. Quite a lot of moving pieces .. someone tested at least ffmpeg's vaapi support on Intel, but because (from my reading of code) we do not do hw decoding in 10bit ... results might be less rosy than by using ffmpeg directly.
I don't know the AV1 hw limits, but it will be of interest to try this codec with FFmpeg (next year) https://trac.ffmpeg.org/wiki/Encode/AV1 So far I just verified that the current prebuild FFmpeg 6.0.1 (packman repo) on Tumbleweed-Slowroll has AV1 Encoder support: ffmpeg -codecs -hide_banner | grep av1 DEV.L. av1 Alliance for Open Media AV1 (decoders: libdav1d libaom-av1 av1 av1_cuvid av1_qsv ) (encoders: libaom-av1 librav1e libsvtav1 av1_nvenc av1_amf ) DEAIL. wmav1 Windows Media Audio 1
