NVIDIA HW Acc. - NoMatch Codec does not support level 'Level 6.2'

[random0815 0]

Hi, i try to enable the decoder for converting movies, but unfortunately, he does not use the GPU.

>>>>>>  FindVideoDecoder - MediaType: hevc, UseHardwareCodecs: True, HWA-Mode: Advanced
Info    Checking: 'CUVID NVIDIA GeForce RTX 2080 Ti - H.265 (HEVC)'
NoMatch Codec does not support level 'Level 6.2'
Info    Decoder does not match
Info    Checking: 'NVDEC NVIDIA GeForce RTX 2080 Ti - H.265 (HEVC)'
NoMatch Codec does not support level 'Level 6.2'
Info    Decoder does not match
Info    Checking: 'Automatic software decoder'
Info    Check successful - selecting 'Automatic software decoder'

Can somebody help me with this problem?

 

Best regards,

 

phil

Hi, looks like your GPU does not support the hevc level of this file. Does that answer your question? It's still using hardware for the encoding, just not decoding.

Your media file is encoded incorrectly. It indicates HEVC level 6.1, which means that it would have a bitrate between 60Mbps and 120Mbps, but actually it has only 7Mbps.

The purpose of codec levels is to ensure that or determine whether certain content is playable on a device when decoding, or when encoding, it is to encode a video in a way that it will be playable on a certain device.

Emby uses codec levels exactly like this (the intended purpose) for choosing a suitable decoder. When a video provides incorrect data, then it needs to be expected that things aren't going as desired..
