Guest mjorud Posted March 27, 2018 Share Posted March 27, 2018 I have both decode and encode enabled in the transcode menu so that is taken care of. Have tested several HEVC files and speed varies from "speed=1.8x" to "speed=4.5x" and both Android Phone and Chrome to play movies. Not very scientific. During testing this popped up in the ffmpeg log (and no video): [hevc_cuvid @ 00000214fedb01e0] ctx->cvdl->cuvidCreateDecoder(&ctx->cudecoder, &cuinfo) failed -> CUDA_ERROR_OUT_OF_MEMORY: out of memory [hevc_cuvid @ 00000214fedb01e0] ctx->cvdl->cuvidDecodePicture(ctx->cudecoder, picparams) failed -> CUDA_ERROR_INVALID_HANDLE: invalid resource handle [hevc_cuvid @ 00000214fedb01e0] cuvid decode callback error Error while decoding stream #0:0: Generic error in an external library I noticed I had three instances of ffmpeg running even though I had no movies transcoding. Two of the instances disappeared after a while but the last instance kept on running. Had to kill it. For some reason Emby does not always kill ffmpeg when stop playing... Regarding the compilation guide, it is very helpfull but does not cover implimentations of --enable-nvenc, --enable-cuda nor --enable-cuvid.

Luke 37272 Posted March 30, 2018 Share Posted March 30, 2018 The next release of Emby Server for Linux x64 will include NVENC support out of the box so all you need to do is enable it. Nvidia Cuda and OpenCL drivers will need to be installed first. These cannot be freely distributed by us so you will need to refer to your respective distro to learn how to install them. Thanks !

I can transcode with my 1050Ti or G4600 in realtime as long as I don't enable bitmap subs (PGS). I would try to play around with the transcoding settings a little bit. Otherwise the P400 is probably just to weak... Which is kind of strange because the P400 and the 1050Ti are in the same price range and the P400 doesn't have any benefits in this department, both cards can only encode two streams at the same time.

Which is kind of strange because the P400 and the 1050Ti are in the same price range and the P400 doesn't have any benefits in this department, both cards can only encode two streams at the same time. All the nvenc engines are the same in Pascal, so it comes down to memory bandwidth, which the GP400 seriously lacks. It has a quarter of the memory bandwidth of a 1050Ti and half the bus width, so it has been seriously hobbled by Nvidia. The Nvidia cards with faster memory can encode faster, but that's about it. https://developer.nvidia.com/video-encode-decode-gpu-support-matrix For those thinking of going to workstation cards, here is the updated matrix from nvidia. It will let you know what cards you want to buy to get the max unlimited streams and what bit depth they support as well. Link to comment Share on other sites More sharing options...

Gerrit507 24 Posted May 16, 2018 Share Posted May 16, 2018 (edited) still no solution for this issue? After a quick google search it looks like a ffmpeg isssue. What you can try is to update to the latest beta version of emby. It comes with ffmpeg 4.0. Maybe it works with that version, because the version in emby stable is very old afaik. Another option would be to switch to linux... Edited May 16, 2018 by Gerrit507 Link to comment Share on other sites More sharing options...
Luke 37272 Posted May 17, 2018 Share Posted May 17, 2018 The version with emby stable is 3.4.2, which isn't all that old. In fact they jumped from 3.4.2 to 4.0 rather suddenly. Link to comment Share on other sites More sharing options...
