[Live-devel] H265 elementary stream plays at half speed

[Paul Westlund]

Hi Ross,

Thanks for the fix.

I was trying it out today, and it seems to fix the issue for H265. However, it now seems to have broken my test video for H264. I have attached a similar video that is encoded in H264. It should run at 60 FPS, but the testOnDemandRTSPServer runs it at 120 FPS. VLC seems to play it correctly.

I wonder if the default value of DeltaTfiDivisor needs to be 1.0 for H265, but 2.0 for H264?

Thanks,

Paul

Paul,

Thanks for the note.  I’ve just installed a new version (2021.06.25) of the “LIVE555 Streaming Media” code that changes the default value of “DeltaTfiDivisor” to 1.0, as this seems to work best for most raw H.265 video streams (like yours).
