Stream Hangs on Amazon Fire TV and Fire TV Stick #33

Closed rwatts9942 closed 8 years ago

rwatts9942 commented 8 years ago

I am streaming HLS and am running into an issue where:

1) On the Fire TV - It hangs at points, for several seconds, and the resumes. It doesn't appear to be a buffering issue as the buffering graphic doesn't appear. It just freezes for several seconds. 2) On the Fire TV Stick - It just hangs and just doesn't seem to recover.

I have a Fire TV but don't have a Fire TV Stick to test with and I suspect that the issue is the same issue. The stick is basically the same as the Fire TV but with less resources. I am getting feedback on the stick from other people and it is possible that they just aren't waiting long enough.

Here is what I am able to log on my Fire TV...

This always occurs right when the hang happens: I/AudioFlinger( 178): BUFFER TIMEOUT: remove(4098) from active list on thread 0xf553d008 D/AudioFlinger( 178): Disable DS for device=0x400profile=0x1 W/CustomAudioPolicyManager( 178): getDeviceForStrategy() unknown strategy: 6 W/CustomAudioPolicyManager( 178): getDeviceForStrategy() unknown strategy: 7 W/CustomAudioPolicyManager( 178): getDeviceForStrategy() unknown strategy: 8

This is consistently logged during the stream when playback is working: E/MFV_COMMON( 178): [Warning] profile: 77, level: 41, bDirect8x8InferenceFlag should be 1 (0) E/MFV_COMMON( 178): u4LevelIdc 41 E/MFV_COMMON( 178): handleSPSNALU() 1 u4LevelIdc 41 E/MFV_COMMON( 178): vdec_drv_h264_decode, u4LevelIdc 41 E/MFV_COMMON( 178): getDpbSize u4NumRefFrames (3), u4DpbSize (9)!! E/MFV_COMMON( 178): [Debug] getDpbSize final u4DpbSize (9)!! E/MFV_COMMON( 178): handleSPSNALU() 2 u4LevelIdc 41 W/MFV_COMMON( 178): [Warning] Multi NAL case 1, 30 W/MFV_COMMON( 178): [Warning] Multi NAL case 2 E/MFV_COMMON( 178): u4LevelIdc 41

Any ideas on how to resolve this?

I am streaming from Wowza servers and using Akamai as a CDN. The streams work fine the web and other CTV devices (e.g. Roku).

@rwatts9942 What did you find? I'm seeing freezes after two instances of "unknown strategy: 6" and then it unfreezes after two more.
