リリース

January 17th, 2022, FFmpeg 5.0 "Lorentz"
FFmpeg 5.0 "Lorentz", a new major release, is now available! For this long-overdue release, a major effort underwent to remove the old encode/decode APIs and replace them with an N:M-based API, the entire libavresample library was removed, libswscale has a new, easier to use AVframe-based API, the Vulkan code was much improved, many new filters were added, including libplacebo integration, and finally, DoVi support was added, including tonemapping and remuxing. The default AAC encoder settings were also changed to improve quality. Some of the changelog highlights:

AMR形式はけっこう使うけどparserとはどういう意味だろ
処理は元から速いからがそっちじゃないと思うけど

amr_parser.cというのが新しく加わっているみたい
今までは外部ライブラリ丸投げだったのが自前で解析することもできるようになった、とかかなぁ

ほーなるほど
重複は避けるべきだからむしろ外部ライブラリを使い続けてほしいけど納得した
ありがとう
