Does iOS support H.265 GDR (gradual decoding refresh)?
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.
