ShakaPackager v3 doesn't generate <BaseURL> in MPEG-DASH manifest so that ShakaPlayer cannot play video completely. #1378

Closed dev-platong closed 3 months ago

dev-platong commented 3 months ago

System info

Operating System: Mac OS 13.1（22C65）x64 and arm64. I had compared behaviour by x64 because packager for arm64 only version after 3.0.2. Shaka Packager Version: 3.0.0 later.

This problem doesn't occurred by 2.6.1.

Issue and steps to reproduce the problem

Packager Command:

any mp4 videos works. 

packager \
  in=big_buck_bunny_720p_surround.mp4,stream=audio,output=audio.mp4 \
  in=big_buck_bunny_720p_surround.mp4,stream=video,output=video.mp4 \
  --enable_widevine_encryption \
  --key_server_url https://license.uat.widevine.com/cenc/getcontentkey/widevine_test \
  --content_id 7465737420636f6e74656e74206964 \
  --signer widevine_test \
  --aes_signing_key 1ae8ccd0e7985cc0b6203a55855a1034afc252980e970ca90e5202689f947ab9 \
  --aes_signing_iv d58ce954203b7c9a9a9d467f59839249 \
  --mpd_output manifest.mpd \

What is the expected result?

Ideal result by 2.6.1.

What happens instead?

But packager 3 omit <BaseURL>. so player cannot identify video and audio files.
