| How to hotpatch "KeyError: 'QV'" on YT | |
| 1. The patch just landed 50 minutes ago here: https://github.com/ytdl-org/youtube-dl/commit/ae8ba2c31977b68b75221f80c488c0b12385269c | |
| 2. Packaged release of youtube-dl is not updated yet, and it is not known when it will be. Meaning that you can't update it via package manager or official website | |
| 3. Official instruction to patch is quite complicated: https://github.com/ytdl-org/youtube-dl/issues/31530#issuecomment-1435975611 | |
| Therefore we will manually cherry-pick the patch... | |
| 4. Find this file: extractor/youtube.py (mine was in /opt due to homebrew installation) | |
| 5. Back it up | |
| 6. Open it in the editor | |
| 7. Locate the line "jsi = JSInterpreter(jscode)" and comment it out |
