Currently i’m working on a new setup that includes UHD resolutions for my live stream. Ideally i want to use HEVC 3840 x 2160 p50, SDR as the Upstream via RTP or SRT protocol. As I’m switching the source from H.264 to HEVC I’m having issues when watching the stream. It seems like either the decoder or the transcoder is not keeping up, my VLC is not showing all frames that it is decoding. In the log file i often times get this message:
MPEGDashWriterHandler.createChunkM4S[live-test/definst/hevc_360p_720]: chunkid: 26 a/v timecode diff = 3.561
Is there special treatment / tuning required for HEVC ingest?
It gets even worse when i go from 25fps to 50. I’m running Wowza 4.7.7 (build 20181108145350) on an AWS M5.24xlarge machine.
Any help is very much appreciated
