During the transition period, when a Libav user typed ffmpeg, there was a message telling the user that the ffmpeg command was deprecated and avconv has to be used instead. Libav then renamed their ffmpeg to avconv to distance themselves from the FFmpeg project. Finally, FFmpeg supported a far wider variety of codecs and containers than Libav.Īs of 2022, Libav is an abandoned software project, with Libav developers either returning to FFmpeg, moving to other multimedia projects like the AV1 video codec, or leaving the multimedia field entirely.Īt the beginning of this fork, Libav and FFmpeg separately developed their own versions of the ffmpeg command. Secondly, Mateusz "j00ru" Jurczyk, a security-oriented developer at Google, argued that all issues he found in FFmpeg were fixed in a timely manner, while Libav was still affected by various bugs. Firstly, FFmpeg had a better record of responding to vulnerabilities than Libav. On July 8, 2015, Debian announced it would return to FFmpeg for various, technical reasons. Hence, most software on these systems that depended on FFmpeg automatically switched to Libav. The maintainer of the FFmpeg packages for Debian and Ubuntu, being one of the group of developers who forked FFmpeg, switched the packages to this fork in 2011. The event was related to an issue in project management and different goals: FFmpeg supporters wanted to keep development velocity in favour of more features, while Libav supporters and developers wanted to improve the state of the code and take the time to design better APIs. It was announced on Maby a group of FFmpeg developers. The Libav project was a fork of the FFmpeg project.
So my final command is: ffmpeg.exe -y -i input.flac -codec:a libmp3lame -q:a 0 -map_metadata 0 -id3v2_version 3 -write_id3v1 1 output. If you want ID3v1 metatags too, you should add the -write_id3v1 1 parameter. The option -qscale:a is mapped to the -V option in the standalone lame command-line interface tool. 0-3 will normally produce transparent results, 4 (default) should be close to perceptual transparency, and 6 produces an "acceptable" quality. Values are encoder specific, so for libmp3lame the range is 0-9 where a lower value is a higher quality. If you want use this option in ffmpeg, you should use the -q:a 0 alias.Ĭontrol quality with -qscale:a (or the alias -q:a). Audible differences between these presets may exist, but are rare. These VBR settings will normally produce transparent results. Very high quality: HiFi, home, or quiet listening, with best file size If you want to save a little space, try the recommendation of hydrogenaud.io:
