GTsitouridis 2 Posted February 13, 2021 Share Posted February 13, 2021 I am trying to enable HW transcoding on emby running natively on RPi 4. But I am always getting Software -> Software. I am trying to stream live TV coming from tvheadend, running on the same RPi. Any suggestion on what I need to check? Thank you Link to comment Share on other sites More sharing options...
Luke 36999 Posted February 13, 2021 Share Posted February 13, 2021 Hi there, did you follow our hardware acceleration setup guide? https://support.emby.media/support/solutions/articles/44001160148-hardware-acceleration-overview Link to comment Share on other sites More sharing options...

The document is not a guide rather a specification list and based on that I should be having HW Transcoding. Since I do not, I guess that I may have not done something. My understanding is that I should be going for VA API, but how can I enable it? Link to comment Share on other sites More sharing options...
Luke 36999 Posted February 21, 2021 Share Posted February 21, 2021 I would just select Yes for hardware transcoding in emby server transcoding settings. If you don't think you're getting hardware transcoding, then let's look at an example: Thanks. Link to comment Share on other sites More sharing options...
GTsitouridis 2 Posted February 21, 2021 Author Share Posted February 21, 2021 When I select simply "YES" then I get playback as Software - Software When I select "Advanced" transcoding, there is nothing checked, so I go about and check them all myself, with kind of partially HW transcoding.

Luke 36999 Posted February 21, 2021 Share Posted February 21, 2021 OK, let's look at an example then. Thanks. Link to comment Share on other sites More sharing options...
GTsitouridis 2 Posted February 21, 2021 Author Share Posted February 21, 2021 Well.... both cases not great. Image quality is ok, but not very sharp.... its a bit smooth. Biggest problem is that in both cases playback freezes for a couple of second every few seconds. That is SW That is semi HW Link to comment Share on other sites More sharing options...
Luke 36999 Posted February 21, 2021 Share Posted February 21, 2021 Can you please attach the log files requested in my link above? Thanks. Link to comment Share on other sites More sharing options...
GTsitouridis 2 Posted February 21, 2021 Author Share Posted February 21, 2021 Ok, so I am including all logs I found under "Logs" hardware_detection-63749544475.txtembyserver.txtffmpeg-transcode-03f0eb65-c251-46bc-9090-f26d304e85d9_1.txtffmpeg-transcode-44e88d80-8cae-48bd-a052-c2d66a1d4f72_1.txtffmpeg-transcode-37200c27-686b-4035-b39d-3bdbc0f88bbd_1.txtffmpeg-transcode-a178c664-6b53-46e9-8acc-7dd052654c67_1.txt Link to comment Share on other sites More sharing options...
Luke 36999 Posted March 4, 2021 Share Posted March 4, 2021 The third ffmpeg log there is using hardware encoding. You're getting software in some other cases because deinterlacing is needed and that's not supported right now by the hardware encoder. Link to comment Share on other sites More sharing options...

I guess that means it is a limitation of the HW of RPi4 and thus it will not be improved right? Link to comment Share on other sites More sharing options...

For now yes, although we'll follow it to see if anything changes. @softworkz may have more insight. Link to comment Share on other sites More sharing options...
