Hello,

I'm trying to play an H.265 video stream, containing no I-frames but using GDR. No video is shown using VTDecompressionSessionDecodeFrame, other H.265 videos work fine.

In the device log I can see the following errors:

AppleAVD: VADecodeFrame(): isRandomAccessSkipPicture fail

followed by

An unknown error occurred (-17694)

Is it possible to play such a video stream? Do I need to configure CMVideoFormatDescription in some way to enable it?

Thanks for your help.
