Cant't transcode with NVENC

Andre-Guy Otis · 2021-01-29T02:03:37+00:00

Hello, I tried to compile tvheadend from git but I can't get the NVENC transcoder working. I configure the build with --enable-nvenc I was able to compile...

Kiril St.

I did some experiments. Replace all code in function profile_sharer_destoy from stable 4.2.8. Now htsp with transcoding work without any problems, but http with transcoding cause tvheadend to crash...

Kiril St.

@ Flole Systems, I investigate a little more, and found that commit be37f9d (profile: reshuffle code in sharer destroy) is caused this problems! Im not familiar with github pull request features, so i provide working code in text file. Please check, and review. Tested wit http and htsp user on same channel, also 2 htsp users on same channel, work without problems!

Thank you so much for identifying this. This should make fixing it a lot easier.

Flole

And I just saw that you provided a fix aswell! Thanks, I will check it out!

First, Many many thanks for this work! Now it Working correctly!
i make a Notic in my Bug Ticket https://tvheadend.org/issues/5417 


Second, I make many Tests with Spawn + FFmpeg (from git) 
-> Result, with HW Decode and HW Filter and other Options is the Performance very nice...


now i Tihnk two Parts open for NVIDIA Transcode (with Decode and HW full offload) 
- HW NV Decode
- update Profile and Presets + HW Filter and Scale and RAM usage (but Filter and Scale is Differnt with new "vulkan" Version)
  -> and i think we need a Sub-Option for HW Decode Config ->> Use Filter, use Scaler, ...

Flole Systems,
have you Preview for NV_Decode?

Flole

I have nvdec working, but I need to test with the latest ffmpeg version to see if it actually works correctly now.

Also the fix on GitHub is not correct yet, it has at least one issue that needs addressing before it can be merged.

With or whithout HW filter (yadif_Cuda, hwupload)?

And can you please send me the Changes i will test this...

Flole

Without hw filter for now.

With the current ffmpeg version things don't work properly yet, so there's no point in sending you the changes. I'll test with the latest ffmpeg and then merge it if it's working.

What do you mean with this? It cause some problems? I dont see any problems so far...just curious...

Flole

It could cause issues, yes. The bottom part is not correct, it has potential issues when multiple threads are executing the code.

Memory is not freed even when using "webtv-h264 (WEBTV codec H264)" CPU encoding.

Each time you switch programs, RAM increases and the number of processes increases.

I have to restart the tvheadend process often.

Flole

Did you compile in the fix from GitHub? Otherwise it's no surprise and nothing new.

That's an ffmpeg issue. You need to report that to ffmpeg.

Before last commit it work

Look what the last commit does, then you will understand why it worked before.

I just did a build using the internal ffmpeg. It works great with nvidia, if you do not select hardware accelerated. I can see the GPU working, CPU level is low, picture quality is great. if HW accelerated is clicked it does the error with filters.

The only issue I see is that dvbsub is not passed when using copy on the streaming profile on VLC based players (tested on IOS and windows with VLC). Oddly enough it works in KODI.

I read somewhere, that this is bug in vlc player, try SMPlayer, works perfect!

Or show output of stream inffprobe

all working quite well. i am noticing these in the log (viewing experience is not affected). just putting this here as a FYI.
