Apple TV lagging

Hi,

First of all thanks for this awesome effort!

We’re running into problems while using shaka-player-embedded on the Apple TV (A1625 - AppleTV5,3). Video playback seems a bit laggy.

The player is using constantly 60-70% of CPU with an occasional 100% CPU load peaks. Those peaks seem to be the reason for laggy playback.

We’re playing unencrypted HLS in fMP4 container, h264 + aac audio:

Input #0, mpegts, from '/tmp/chunk.mp4': Duration: 00:00:05.01, start: 11770.739911, bitrate: 5127 kb/s Program 1 Metadata: service_name : Golf Channel HD [DVL] service_provider: kuki Stream #0:0[0x100]: Video: h264 (Main) ([27][0][0][0] / 0x001B), yuv420p(progressive), 1920x1080 [SAR 1:1 DAR 16:9], 25 fps, 25 tbr, 90k tbn, 50 tbc Stream #0:10x101: Audio: aac (LC) ([15][0][0][0] / 0x000F), 48000 Hz, stereo, fltp, 131 kb/s Stream #0:20x102: Audio: aac (LC) ([15][0][0][0] / 0x000F), 48000 Hz, stereo, fltp, 132 kb/s

Do you guys have any suggestions? We’ve tried release build with full optimizations of course but it seems to make little to no difference.

Unfortunately, our test stream URL can not be posted publicly but I can provide it in private communication.
