- All content keys were redacted, they should be 128-bit hex strings.
- These methods involve the use of ffmpeg and -cenc_decryption_key which is not part of stable releases as of July 2022. Use nightlies from gyan.dev or some other autobuild in the meantime. Hopefully it gets added in the next stable release.
- On my end none of these were particularly reliable. This may change in the future as FFmpeg evolves. The direct method of playing with ffplay is currently the most reliable out of the listed methods.
