[dfvips]

System Info

Operating System: Windows 10 x64
Shaka Packager Version: Latest release

Issue and Steps to Reproduce the Problem

Packager Command:
packager-win-x64 --quiet --enable_raw_key_decryption input="vvc1.mp4",stream=0,output="vvc1.dec.mp4" --keys key_id=b130cf2734fa9725fe8f0fb83bee2e4a:key=8e8680e327573152942a6517a9a5d5ee

Steps to Reproduce

1. Download the test video file from the provided link:vvc1.mp4
2. Run the above command with a VVC1-encoded video file encrypted with Widevine keys.
3. Observe the error in the logs.

Expected Result

Successful decryption and output of the decrypted vvc1.dec.mp4 file.

Actual Result

The decryption process fails, and the following errors are logged:

Test File

You can use the following test file to reproduce the issue:
vvc1.mp4

Additional Information

1. The error log indicates that the vvc1 format is not supported in the current version of Shaka Packager.
2. The test file and Widevine keys work successfully with FFmpeg and mp4decrypt, indicating that both tools currently support VVC1 decoding and decryption.
3. This issue occurs specifically with VVC1 encoded media and Widevine decryption keys.

Request

Please advise if there are plans to add support for the vvc1 format in Shaka Packager or provide a workaround for this issue.
