stable download URL and version?

[hayguen]

just noticed, that i commented / asked on the closed issue #199; now deleted the comment there.

i'm not sure, if i have the same issue as @237dmitry .. but it sounds similar enough!

as i describe in yt-dlp#31, i would like to determine automatically, if there's need to download a new version of ffmpeg, e.g. https://github.com/BtbN/FFmpeg-Builds/releases/download/latest/ffmpeg-n5.1-latest-linux64-gpl-5.1.tar.xz listed in https://api.github.com/repos/BtbN/FFmpeg-Builds/releases/latest from the 5.1 release.

one way might be, if ffmpeg -version would output one same comparable id, e.g. the git commit/sha-id, which can also get identified/found in the name or browser_download_url field of the assets list in https://api.github.com/repos/BtbN/FFmpeg-Builds/releases/latest

Like I said in that issue already: There's new commits to master almost every day. So you can safely assume that there's been some changes.

The daily releases have exactly what you are asking for in the file name. What else are you looking for?

[BtbN]

Maybe you missed that there's two releases every day? One with specific version numbers, and one which is just "latest" so there's stable URLs that never change.
The "latest" release is recreated every day.

Also: Even if the ffmpeg version did not change, the dependencies very well might have been upgraded.
For example, on Monday there will be the critical openssl update. The version number of the release-builds won't change, yet you very much will want to use the latest version of them.

@BtbN : you mean, that https://github.com/BtbN/FFmpeg-Builds/releases/download/latest/ffmpeg-n5.1-latest-linux64-gpl-5.1.tar.xz really changes every day (2 times)?

dependency updates: hmm, didn't think on those

[BtbN]

That link will be re-built every day, yes. If something changed depends on if something was pushed to the 5.1 release branch that day, or if dependencies were updated (which won't be reflected in the version number whatsoever)

@BtbN ooookay. Thank You for clarification.
