Hi! Maybe anyone faced the same or similar issue and can show me the direction to solve it. I faced the issue that Emby can't decode H265 (HEVC) on my hardware that suppose to do it. My hardware: Intel NUC 5I5RYH (Intel Core i5 5250U, Intel HD Graphics 6000). I use Proxmox. Emby installed via LXC. Hardware acceleration works fine as long as it is for H264. It works via Quick Sync as well as via VAAPI. But recently I tried to play HEVC movie and faced issue that direct play works fine but any video transcoding (bitrate limit) leads to full stop. As far as I know my hardware must be able to decode HEVC well. Emby shows me such an option in advanced settings. I attached a few logs: 1) Hardware detection log 2) Emby server log 3) Transcode H265 -> H264 log (with issues using Quick Sync) 4) Transcode H264 -> H264 log (no issues using Quick Sync). There is also no issues H264 -> H264 using VAAPI but didn't attach the log. ---- A few highlights: >>>>>> FindVideoEncoder - MediaType: h264, UseHardwareCodecs: True, HWA-Mode: Automatic Info Checking: 'VAAPI HD Graphics 6000 - H.264 (AVC)' Info Check successful - selecting 'VAAPI HD Graphics 6000 - H.264 (AVC)' >>>>>> FindVideoDecoder - MediaType: hevc, UseHardwareCodecs: True, HWA-Mode: Automatic Info Checking: 'QuickSync HD Graphics 6000 - H.265 (HEVC)' Info Check successful - selecting 'QuickSync HD Graphics 6000 - H.265 (HEVC)' >>>>>> Processing Plan Name CanDoInHW WillDoInHW Reason QuickSync HD Graphics 6000 - H.265 (H... >> True True Hardware Codec VideoInput >> False False Incompatible hardware context.
