@BucherTomas
Do you know any expert in AVPlayer or Fairplay? Thanks.

[BucherTomas]

@tongwu460 No, I don't.

However, in your case I'd say that this older Apple TV model simply does not support HEVC + FairPlay combination. The attached log contains the error "CoreMediaErrorDomain error -12885 - unsupported crypt format.". Some time ago I was trying to solve a similar issue in Safari which shares a lot of the media processing pipeline with native AVPlayer. And I did not receive any usable feedback whether there is an actual line of devices that might fail while others would work, see https://bugs.webkit.org/show_bug.cgi?id=195460. I still believe that is the case.

Also make sure that your stream follows Apple's HLS authoring specification and avoid using "hev1" codec setup to be safe. See
"1.10. You SHOULD use video formats in which the parameter sets are stored in the sample descriptions, rather than the samples. (That is, use 'avc1', 'hvc1', or 'dvh1' rather than 'avc3', 'hev1', or 'dvhe'.)" at https://developer.apple.com/documentation/http-live-streaming/hls-authoring-specification-for-apple-devices

@BucherTomas Thanks, I will test and feedback.

@BucherTomas I have change the codecs to hvc1, still the same story...

@tongwu460 As mentioned previously, that particular device does not support the HEVC + FairPlay combination at all in my opinion, it will likely require just H.264 when using FairPlay.

The suggestion to change the codec to hevc1 configuration is just in line with Apple specification to make sure you avoid running into other issues on other, more capable Apple devices. It was not expected to make a difference on A1625.

[tongwu460]

@BucherTomas OK,thanks.
