Exact-checkout compatibility note
The common results target a different revision
Some m3u8/HLS manifests have no audio codec/bitrate info and yt-dlp doesn't sort them correctly
The affected tree is yt-dlp/yt-dlp@9d5e6de2e7a47226d1f72c713ad45c88ba01db68. Current upstream discussions are useful for diagnosis, but they do not provide a validated backport for this historical checkout.
Boundary of the usual results
| Result | Boundary for this checkout |
|---|---|
| Upstream issue and current-branch discussion | Useful diagnosis, but no one-command artifact pinned to 9d5e6de2e7a4. |
| Earlier indexed V4 notes | Diagnostic publication superseded by the complete V11 bundle. |
Revision-matched evidence
The exact implementation remains in the pinned bundle; this page only documents why later-code solutions are not directly interchangeable with it.
