As already posted in another thread, there is an issue with playback of specific TS streams. I repost/crosspost here, as the same issue is replicated with VLC for tvOS.
It is a decrypted TS stream recorded (and decrypted) from SKY - but same happens with LiveTV.
I now have a recorded stream at hand. It is about 10 Minutes in length, ~600 MB and I can share it.
This stream runs fine till 1:28 (88 seconds), then playback of audio and video stops, but progress indicator and time display continue as normal.
Debugging in my App using VLCKit shows my a deadlock with Decode Thread and some related threads. They stop at pthread_cond_wait() - not sure what they are waiting for.
If you prefer I could also enter a defect for this.
Please share the location, where I can upload the TS stream for further investigations on your side.
