Packager fails to encrypt AVC3 format mp4 file

[SingingTree]

System info

Operating System: Windows 10
Shaka Packager Version: packager-win version v2.3.0-5bf8ad5ed5-release

Issue and steps to reproduce the problem

• Download and extract ConcatMediaSourceTestFiles.zip -- this is an mp4 that contains inband SPS data and uses the AVC3 format.
• Attempt to encrypt it using the command:

packager-win.exe in=ConcatMediaSourceTestFiles.mp4,stream=video,init_segment=ConcatMediaSourceTestFiles_video_init.mp4,segment_template=ConcatMediaSourceTestFiles_video_$Number$.m4s --protection_scheme cbcs --enable_raw_key_encryption  --keys label=:key_id=7e571d047e571d047e571d047e571d21:key=7e5744447e5744447e5744447e574421 --iv 11223344556677889900112233445566

What is the expected result?

The file would be encrypted. Ideally the file would not be remuxed using the AVC1 format as I'm attempting to create test media for the encrypted AVC3 case.

What happens instead?
