NVENC experimental

[cptbstd 0]

Hi, having some sucess and some failures currently running on running on Windows server 2012 r2 with Emby 3.0.6000.0. I have a nvidia quadro k2000 with driver 368.86. I enable NVENC experimental. Some videos work, some do not.

Thanks for the info. It's very new to us so we're still looking to find what works and what doesn't. Thanks.

HDHomeRun live tv does not work with this option enabled, i get an error saying there was a problem playing 

[Luke 38803]

Good info, thanks.

Hello guys little question. Despite the fact that I need to select NVENC in transco options, do I need a special version of FFMPEG? Seems that I still have the version of 5/08/2016 (I have the version 3.1.90.0 of the server). When I go into transco logs, I don't see any reference of NVENC... Thx.

Yes. You need to supply your own version for nvenc.

Ok thx but... Where am I supposed to find it?

You will need to build it on your own as the nvenc licensing does not allow it to be redistributed, which is why none of the sites that host ffmpeg include it within their build.

Is there a tutorial or at least the link where I can download sources?

This might have changed recently, as Nvidia has relicensed the header file that was in contention with ffmpeg's license. I would have to double check, but I believe recent Zeranoe ffmpeg builds include nvenc encoder support.

 

If needed, I might have a bookmark with the commit that removed the nonfree configure/compile switch requirement.

 

Edit: Found it here.  Light discussion is here.

Hello guys. I get the 64 bits static of FFMPEG Zeranoe version. I tried, it seems to start well. But yesterday I tried with too different movies, and I don't know why but after several minutes it just stop playing. I tried with IOS clients.

 

Here are two logs.

transcode-3b4f2ee5-d604-4485-9e46-616f21e95cc6.txt

transcode-00460464-8e58-47c8-8287-9b44fc222881.txt

[jscoys 147]

Notabene : When I switch the option from NVENC (Experimental) to "None" in the transco method, it just work fine, and I'm able to play the whole movies.

Is it working for you?

I'm not sure it's actually included yet in the zeranoe builds.

[Waldonnis 148]

All of my media is encoded to not require transcoding on any of my devices, so I don't use it for Emby transcoding.  I do use the Zeranoe builds for other purposes and have used the h264 and hevc nvenc encoders for testing purposes recently.  It's fussy, but works well enough for what the hardware encoders are designed to do.  Be aware that the hardware encoders aren't as featured as x264 is (or x265), so they may not work with some files/operations.

 

I'm not sure it's actually included yet in the zeranoe builds.

It is. I just downloaded the ffmpeg-20160812-e8b355a-win64-static build and they were listed in the encoders:

 V..... h264_nvenc           NVIDIA NVENC H.264 encoder (codec h264)
 V..... h264_qsv             H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10 (Intel Quick Sync Video acceleration) (codec h264)
 V..... nvenc                NVIDIA NVENC H.264 encoder (codec h264)
 V..... nvenc_h264           NVIDIA NVENC H.264 encoder (codec h264)
 V..... hap                  Vidvox Hap encoder
 V..... libx265              libx265 H.265 / HEVC (codec hevc)
 V..... nvenc_hevc           NVIDIA NVENC hevc encoder (codec hevc)
 V..... hevc_nvenc           NVIDIA NVENC hevc encoder (codec hevc)
 V..... hevc_qsv             HEVC (Intel Quick Sync Video acceleration) (codec hevc)

I can run a test encode if needed, but the encoders seem to at least be listed and showing their respective options.

I downloaded the new version of today, static too. I really don't know if it is using GPU or not... Luke if you need to test you can rely on me. The next step for Emby is to use different versions of ffmpeg and when selecting the option of transco, Emby would select the proper ffmpeg.

Ah great info, thanks.

[jscoys 147]

Further tests : for different movies tested, it works well (not like my previous post where I explained that it blocked after several playback minutes...

 

Seems to start really quicker than before (when CPU was used).

 

In the logs I can see the parameter -enable-nvenc so I suppose it is enabled (if not please explain me how to see in logs that nvenc is indeed used)

 

- cpu is use at 45-50% in peek time (compared to 90-95% before). In idle state it remain around 13%.

 

Will give you more info when I Will test it in real conditions.

So NVENC now works? That's great news.  Well not really as NVENC still limits us to 2 streams for those of us without Quadros haha.

 

Does anyone have a 10xx series card? They are supposed to be able to do 10bit x265, so it will be interesting to see what streams Emby decides to encode it as.  Most of my people use roku's or android boxes that can direct play everything, except for my 12bit anime haha.

[jscoys 147]

I have a 750 ti which is able to decode h265 hw but only 8 bits... Anyway i haven't the beautiful tv 4K with 10 bits/pixel so it's useless for me.

 

As you said, excepting ET, no Emby clients would support 10 bits right?

I can direct play 10bit hevc files to my S905 box through SPMC or Kodi, or any other external media player, as VLC support for amilogic is bad and probably won't get better haha.  I don't know if I am getting 10bit colour though as I don't know if my RCA 4k tv is 10bit or not, as the tv doesn't exactly exist on their website, and it might be a Canadian exclusive.  

[jscoys 147]

The "freeze" movie situation has returned unfortunately...

 

If I use NVENC with Zeranoe FFmpeg, version 64 bits or 32 bits (Doesn't matter), movies are transcoded well during 3 to 5 minutes and then stop playing suddently. If I go into dashboard and look to the movie currently playing, the little bars bellow (Green and Red) are aligned, and the red bar, corresponding to transco, doesn't wan't to go on anymore as expected...). And it makes me wondering if NVENC is really activated or not...

 

One more time : if I deselect NVENC and put "none" option it works... So I guess it's not a problem coming from Emby, but from zeranoe which doesn't like the option "--enable-nvenc"... do anyone else has the same problem?

I have the same problem but i only use emby for streaming live tv. It starts transcoding on the GPU and then stops at the 7 second mark. If you are running windows you can use GPUZ to see the stats of the video card. I can see when the transcoding starts and when it stops at the 7 second mark. It is interesting to note that this only happens with HD channels and if i playback a SD channel it has no issue playing for however long i need it to.
