FairPlay Streaming: Calling copyPixelBufferForItemTime on AVPlayerItemVideoOutput returns NULL

Question

Has anybody had experience using HLS with Fairplay and succeeded in retrieving the pixel buffer?

I\'m using an AVURLAsset with its resourceLoader<

Answer 1

i met the same problem when using an AVURLAsset with its resourceLoader delegate set. Different from your situation, there are two kind of live streaming decrypted content, and one of them can retrieve the pixel buffer another can't. I am not sure if it is related to the content of the m3u8 file.

The content that can retrieve the pixel buffer, and get thumbnail.
