- exhilaration 4y agoThis mostly looks like they're adding support for new codecs, there's only 4 new options in there, which seems rather paltry for a dot zero version release. Should we consider ffmpeg feature complete?
- gyan 4y agoDot zero releases basically signify major bumps of the core libs, and are not really synced with user-facing feature changes.
- cm2187 4y agoI am still using 4.2. Does it make any difference if all I care about is h264 and hevc?
- LtdJorge 4y agoMore modern x264/x265 I guess
- bsenftner 4y agoAt a prior job we pinned to 4.2.3 because after that version an internal change massively impacted high frame rates. With a 1080p mp4 file on disk, and that disc being an ssd, version 4.2.3 delivers 700-800 frames per second, while all the versions after that 4.2.3 release - no other app or library changes - that same file may reach 300 fps. I spent some time trying to find the cause of that 50% cut in efficiency, but never found enough time. Curious to try this version.
- esperent 4y ago> I spent some time trying to find the cause of that 50% cut in efficiency Presumably they have an issue tracker. Did you report this?
- bsenftner 4y agoWhen I looked, it had been reported already.
- cstejerean 4y agodo you have a link?
- mixmastamyk 4y agoYou are referring to (re)encoding a file?

- FranOntanaya 4y agoNostalgia moment with the CrystalHD decoder deprecation. That came along the Intel Atom netbooks, one of the few ways we had to bump a bit their austere performance.
