Tvheadend

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 in ffprobe

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

Just like to say that it works for me too (after applying the fix to profile.c) in Kodi.

However, I can't get the codec preset to work correctly. I think nvenc now needs p1 ... p7 rather than Slow, Medium or Fast etc. The only option that does not throw a warning is Default.

Would it be possible to add these options when using nvenc?

Did the update to 4.3-1966~g04853f0da. it's running well. still getting the same messages as my previous post, but it's running.

I am facing same issues using NVENC transcoding. My tvh version is tvheadend_4.3-1975, but the same is with 1940.
I thought, it is an nvidia driver issue, so i tried few versions. But it is always the same. Then i found, that if Watching via kodi, it looks like session is not exited correctly and remains running in gpu memory (nvidia-smi), but When using vlc, memory is clearing itself fine (same profile). One session takes around 80MB, so after 50 chanell changes, only sound remains :-)

So you aren't facing this issue but you're facing the "session not cleaned" issue? There's a patch for that on GitHub (which is not perfectly correct but works for now), so you might want to try that.

@ Flole Systems can be maked more detailed check and informing message when some of them missing.

@ 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!

WORKS! T H I S is the best job that ever been done!!!

This beatifull fix unfortunately is still NOT includet in official TVH git repo -.- why?? its 7 month ago ?

It's not beautiful and definitely not the best job ever done as the code is not thread-safe. That's why it's not included yet. If a proper fix is provided it can be reviewed and then possibly be merged.

Аre there any specific guidelines, or is this a general impression,
what exactly needs to change?
Exact direction.

The purpose of the exercise is to improve the product,
not to refuse developers to offer code due to unclear explanations.

I do not believe that anyone will mind if a corrective code of proposals is proposed.

Тeam work.

This job is basically to revert specific change, a little tweaked to match current code. Thanks must go to Flole Systems for pointing right place, where we look!

sooo when i say the most beautyfull code i mean im wayting for more than a Year of a fix like that. It was painfull. And now im happy that someone find a fix that workes as it should

Agree with that. Great feature, but with this bug is useless!

Please Please Please can we get someone to look into this code so that it can be merged into the master branch? I need to use nvenc to transcode for my low powered Kodi client because spawn will not work with kodi htsp plugin.

Very grateful for all the hard work but there has not been any progress for a year now.

I am begging.

Should be fixed now.
