[Bug] PlayReady DRM dont works on android #1642

Open CastagnaIT opened 3 weeks ago

CastagnaIT commented 3 weeks ago

Describe the problem

With recent changes i was testing Smoothstreaming manifest with playready DRM and i noticed that was not working on my Nvidia shield

i tested ISA on Kodi 18/19/22 on all versions Playready is broken

now Nvidia shield is my only device that should support playready DRM then i cannot make a comparison with another device to say if it is a Shield problem or a ISA problem

here i add the two test streams that come from Microsoft servers (read strm txt for license urls) SMOOTHSTREAM - DRM superspeedway.strm.txt SMOOTHSTREAM - DRM tearsofsteel.strm.txt

these two streams works correctly on Shaka player under Edge browser, i tried to compare ISA saved license files ".init" and "response" and compared with the browser license request/response data, and i havent found particular differences that can explain the problem

on logcat is possible to see many lines of system errors

i have also prepared a DASH with playready test stream DASH_playready - Tearsofsteels.strm.txt

Tested on a Shield TV and a FireTV 4K and both have the same problem:

2024-08-20 11:22:47.945 T:8218     info <general>: AddOnLog: inputstream.adaptive: Manifest successfully parsed (Periods: 1, Streams in first period: 15, Type: VOD)

Here is the debug.log from the FireTV:

@Uukrull can you play SMOOTHSTREAM - DRM tearsofsteel.strm.txt attached above on the FireTv and provide the logcat? maybe the system can show something else useful (remember also to enable Kodi debug setting)

The spinning wheel is stuck and nothing is played with that strm.

there are two problems 1) if the WRMHEADER dont contains LA_URL inside DATA, then can fails, looks like a implementation bug of android playready https://github.com/google/ExoPlayer/blob/dd430f7053a1a3958deea3ead6a0565150c06bfc/library/core/src/main/java/com/google/android/exoplayer2/drm/FrameworkMediaDrm.java#L491-L496 this can be fixed bu reconstructing the WRMHEADER. But for now we can use sample streams that have LA_URL inside DATA to skip this problem 2) The unknown problem, FIretv logcat is much more detailed than shield, seems there are similar errors

both complains of invalid KID

found a old issue on exoplayer with same errors, maybe similar problem https://github.com/google/ExoPlayer/issues/5855#issuecomment-492179782

@Uukrull can you test on FireTv if at least one of these strm works STRM_PR_ISA.zip

by using test build: https://jenkins.kodi.tv/blue/organizations/jenkins/xbmc%2Finputstream.adaptive/detail/PR-1668/7/artifacts

Uukrull commented 1 week ago
