(see footnote 1). + - `unset` is now never a valid codec. Use `auto` instead. + - `unset` is now not a valid bitrate value. Use `auto` instead. - Removed the `--extras` and `-qscale:v` cli options. - The `ae-ffmpeg` pypi package is deprecated and will be removed in a future release. Future versions of auto-editor will not ship ffmpeg cli binaries. - - The `--my-ffmpeg` and `--ffmpeg-location` cli options are deprecated and can be removed in a future release. + - The `--my-ffmpeg` `--ffmpeg-location` `--show-ffmpeg-commands` and `--show-ffmpeg-debug` cli options are now deprecated and can be removed in a future `26.x` release. ## Features - - Remove all uses of ffmpeg-cli for video rendering; improves performance by ~20% - * Using `--my-ffmpeg` no longer means that libx264 (and friends) would necessarily be used. Instead, use a GPLv3 build of PyAV. + - Auto-Editor is consistency twice as fast as `25.x` if `-c:a pcm_s16le` is set. + - Auto-Editor is now 20% faster to 50% slower with default options. (see footnotes 2 and 3). + - Remove all uses of ffmpeg-cli in auto-editor, with the exception of a few holdouts (EBU norm, audio mixing, yt-dlp). + * using GPL vs LGPL builds of PyAV now determine if the `libx264` or `libopen264` encoder is used. ## Fixes - Never write a "null frame" if the timeline is known to be linear. Fixes #468 +## Footnotes + - [1] You can preview media files if they are in the Matroska format (`.mkv`). Although `.mp4` hybrid could theoretically work, ffmpeg does not appear to have sufficient support yet. YMMV with other formats. + - [2] Smaller files perform better. Larger files perform worse compared to `25.x` when using a solid state drive/fast storage. + - [3] It should be possible to eventually recover this lost performance. Either with multiprocessing, or multi-threading with GIL-free builds of Python. + +## Known Regressions + - Data Streams, Attachment Streams, and Embedded Image (video) streams are now always dropped due to some limitations with the current version of PyAV. This should be fixed in a future version of `26.x` + **Full Changelog**: https://github.com/WyattBlue/auto-editor/compare/25.3.1...26.0.0
