NormSwarm 12 Posted March 26, 2020 Share Posted March 26, 2020 (edited) Hello, I'm trying to get the HW transcoding to work on my odroid HC2 (it's the same chipset as the XU4). I'm getting green line everytime I set the HW transcoding with V4L2 (OpenMax doesn't work and fallback to SW). I'm using Amrbian with kernel 5.4.19 and Emby 4.5.0.1 for armhf. Moreover, the HW transcoding is slower than using SW transcoding. ffmpeg-transcode-a4ab62d8-bc98-4420-adbc-664103ad888b_1.txt Edited March 26, 2020 by NormSwarm Link to comment Share on other sites More sharing options...

NormSwarm 12 Posted April 15, 2020 Author Share Posted April 15, 2020 @@LukeIf I downgrade the kernel back into a stable version (4.14.y), Emby Beta 4.5.0 doesn't run, it crashes with a segfault as soon as I access the dashboard. Same if I try to run Emby stable 4.4.2.0. The problem also is the kernel 5.6.y isn't stable at the moment, I had to go back to 4.14.y, but by doing so, Emby doesn't work anymore.

Luke 37019 Posted April 15, 2020 Share Posted April 15, 2020 What do you mean by the kernel not being stable? Do you know what the issue is? Link to comment Share on other sites More sharing options...
NormSwarm 12 Posted April 15, 2020 Author Share Posted April 15, 2020 (edited) The kernel 5.4.y for the Odroid XU4 is still considered unstable. (cf : https://forum.armbian.com/topic/13742-odroid-hc2-kernel-5430/ & https://dl.armbian.com/_test-reports/2020-04-14_23.51.46.html ) The memory module will crash randomnly when trying to allocate pages. About Emby, on 4.5.0.6 with kernel 4.14.y, emby crash either by doing some memory violation ( http://ix.io/2icL ) at boot or when reaching the dashboard. Or also crash at Boot on on LibraryChangedNotifier:pr 15 14:59:39 dolma.hole emby-server[18409]: Info App: Starting entry point Emby.Server.Implementations.EntryPoints.AutomaticRestartEntryPointApr 15 14:59:39 dolma.hole emby-server[18409]: Info App: Entry point completed: Emby.Server.Implementations.EntryPoints.AutomaticRestartEntryPoint.
