The log you posted is just the thumbnail creation ... they all work I tested all of them. Need to see the correct log.

I am pretty sure that the transcoder automagically transcodes h.265 files to play back to SageTV extenders. I am just using the built in transcoding that runs automatically in the recent versions of SageTV for unRAID.

My HD300s generate an error every time I try to play a h265 file, so something is not right about my configuration.

Ideas?

So strangest thing... I obviously copied the wrong bit of log, so I went back just now to find it - it was gone. So I tried to make it happen again and it suddenly worked just fine on the same recording with the same settings... I guess it's ok now

lol thanks!

Can you post the related log from SageTVTranscoder.log? I do not think I even tested this scenario. I would need to pull an HD300 out of storage to even test it.

EDIT: I went out to my garage and tested on a HD300 I have out there, and it worked flawlessly. It looks like it encodes to 720x480 in dvd format. Not sure if that can be increased or not. What OS are you running SageTV on? What version of this plugin are you using?

Will do. This will take a minute, because I exhaustively transcoded all my h265 files to h264 with Handbrake. But happy for the help and will respond as soon as I can!

Hi Josh,

Thanks for adding my Jan 2022 wish list item, Cuda (NVENC) support for Nvidia hardware, to the transcoder.

Now that I have 1.1.0 installed how do I go about testing with it?

Is there a command line we need to add to the transcoding profiles to enable it?

Generally speaking, SageTVTranscoder is a modified version of ffmpeg. So you can call it directly from the command line like you would ffmpeg. So I would start by testing out the new settings on the command line, then building a profile for SageTV from those command line switches. Here is a link that should be helpful: https://developer.nvidia.com/blog/nv...%20processing.

Sounds good, thanks.

Initial NVENC testing...

I am testing with this file which had not yet been converted to MKV yet. I am using an NVidia GeForce RTX 2070 Super (8GB) desktop GPU.

FBI International - S01E17 - Uprooting - 1368600-0.ts

Renamed it Original.ts to make the command line easier. Only using the first 10 minutes to test with.

From the link you provide I put together a working command line and have started tweaking wanting to try the different presets

https://trac.ffmpeg.org/wiki/Encode/H.264

When I use one of the failing presets it shows:

https://developer.nvidia.com/blog/in...dk-10-presets/ (Sorry, you might need an NVidia developer account to get to this page. Here's the important info from there)

Quote:

All NVIDIA GPUs starting with the Kepler generation support fully accelerated hardware video encoding, and all GPUs starting with the Fermi generation support fully accelerated hardware video decoding through the NVIDIA Video Codec SDK.

The NVIDIA NVENC presets design in Video Codec SDK 9.1 and earlier evolved based on various NVENC use cases, which have emerged over time. The presets exposed in the NVENCODE API currently are as follows:

Latency-sensitive encoding:
LOW_LATENCY_HP (Low latency high performance)
LOW_LATENCY_DEFAULT
LOW_LATENCY_HQ (Low latency high quality)

Latency-tolerant encoding:
HP
DEFAULT
HQ

Blu-ray-compatible encoding:
BD (Blu-ray-compatible)

Lossless:
LOSSLESS_HP
LOSSLESS_DEFAULT

These presets evolved over the years, with multiple hardware generations and encoder features getting introduced in each generation. Because NVENCODE API guarantees binary backward compatibility, it has been difficult to reorganize the presets. This has led to many problems:

A large number of presets—There are currently nine presets, but they often have an inadequate quality or performance tradeoff.

Non-uniform preset behavior for different resolutions—For example, a frames per second rate (FPS) improvement of 60% is achievable on Turing by just 2% BD-BR degradation from the Low Latency High Performance preset.

Quality compared to performance—The HQ preset doesn’t always provide the best quality with lower performance. Up to a 5% bitrate savings is achievable on some clips.
To address these issues and give you better control, new presets are being introduced in Video Codec SDK 10.

Preset design
The preset designs in Video Codec SDK 10 are built for better control and granularity over performance compared to the quality tradeoff for NVENC. This gives you more flexibility. The following major changes have been introduced for improved flexibility:

Tuning information—Specify the use scenario:
High quality
Low latency
Ultra-low latency
Lossless

Predefined presets— Choose from a set of seven predefined presets, from P1 (fastest, lowest quality) to P7 (slowest, highest quality). This determines the set of tools used for the encoding: for example, GOP structure, B frames, look-ahead encoding, and so on.

Simplified rate control modes—Choose VBR/CBR/constant-QP encoding and set the desired bitrate and mode (1-pass or 2-pass). If you are using the 2-pass rate control mode, you can choose whether to run the 1st pass in quarter resolution.

I also tried using the newer NVidia presets which should be in ffmpeg, P1 to P7, but they give similar errors.

https://gist.github.com/nico-lab/c2d...c1eafeb52a21c3

Found that page and it actually shows the integer values for the different presets. So I tried 12 for P1, but it gives an out of range error.

Quote:

Based on that error it looks like what we have in place is the older SDK 9.1

Notice the following in your log file for every encode. The Peek and LastError lines continue until the encode is done.

Here is a couple of other good links of info on NVidia encoding:

I had sent all of this to Josh and he mentioned he was going to see if he can include the newer version on the SDK in the build process.

I did some testing on my laptop, the only machine I have with a graphics card

, and confirmed your findings. Hopefully this weekend I will get some time to play with the build a bit and see if I can get a newer SDK working.

So I did some digging on the way I am compiling the cuda support. I am doing it the newer way that FFmpeg has it setup where I only need the headers, and not the nvidia sdk. I think I am good there.

Here is a command to get all of the presets sagetvtranscoder.exe -h encoder=h264_nvenc. You will see there is a pretty long list

CptKirk · #**174** 07-27-2022, 07:31 PM

Yes, but those are the SDK 9.1 presets I believe, 0 to 11.

Code:

h264_nvenc AVOptions:
  -preset            <int>        E..V...... Set the encoding preset (from 0 to 11) (default medium)
     default         0            E..V......

     medium          2            E..V...... hq 1 pass
     fast            3            E..V...... hp 1 pass
     hp              4            E..V......
     hq              5            E..V......

     lossless        10           E..V......
     losslesshp      11           E..V......

The new presets with SDK 10 are 0-18, with 12-18 being the new ones. SDK 10 also added the -tune setting.

Code:

hevc_nvenc AVOptions:
  -preset            <int>        E..V....... Set the encoding preset (from 0 to 18) (default p4)
     default         0            E..V....... 
     slow            1            E..V....... hq 2 passes

     p2              13           E..V....... faster (lower quality)
     p3              14           E..V....... fast (low quality)
     p4              15           E..V....... medium (default)
     p5              16           E..V....... slow (good quality)
     p6              17           E..V....... slower (better quality)
     p7              18           E..V....... slowest (best quality)
  -tune              <int>        E..V....... Set the encoding tuning info (from 1 to 4) (default hq)
     hq              1            E..V....... High quality
     ll              2            E..V....... Low latency
     ull             3            E..V....... Ultra low latency
     lossless        4            E..V....... Lossless

I believe I got those right.

I check both h264 and hevc, both show 0 to 11:

C:\SageTV64\SageTV\SageTVTranscoder.exe -h encoder=h264_nvenc

C:\SageTV64\SageTV\SageTVTranscoder.exe -h encoder=hevc_nvenc

I saw a note in another post online: FFmpeg published the new codec headers 10.0.26.0: https://github.com/FFmpeg/nv-codec-h...tag/n10.0.26.0

With the latest 10.x being 10.0.26.2: https://github.com/FFmpeg/nv-codec-h...tag/n10.0.26.2

I also found that the original presets I tested were for the x264 encoder (GPL) run on the CPU, so that was why a most of them didn't work. The three that did work was just because they had the same name for h264_nvenc as for the x264 encoder (GPL).

I will go back and retest for all of the h264_nvenc 0-11 presets that we have available.

I believe I got those right.

I check both h264 and hevc, both show 0 to 11:

C:\SageTV64\SageTV\SageTVTranscoder.exe -h encoder=h264_nvenc

C:\SageTV64\SageTV\SageTVTranscoder.exe -h encoder=hevc_nvenc

I saw a note in another post online: FFmpeg published the new codec headers 10.0.26.0: https://github.com/FFmpeg/nv-codec-h...tag/n10.0.26.0

With the latest 10.x being 10.0.26.2: https://github.com/FFmpeg/nv-codec-h...tag/n10.0.26.2

I also found that the original presets I tested were for the x264 encoder (GPL) run on the CPU, so that was why a most of them didn't work. The three that did work was just because they had the same name for h264_nvenc as for the x264 encoder (GPL).

I will go back and retest for all of the h264_nvenc 0-11 presets that we have available.

The preset differences are really interesting. I am not sure why they are different. I am actually using the latest version of the nv-codec-headers. I think it is actually up to version 11.

New beta has been posted to my Patreon subscribers. I have upgraded the base FFmpeg code in the project from 4.3.1 -> 4.4.3. This is a fairly big change, so I am going to let them review it for a while before I open up the beta to everyone. Just want to let you guys know that there is work going on.

Thanks,
Josh

Always appreciated what you’re doing. I’ve never used the transcoding software built into Sage - can it be used in a batch circumstance, aka transcoding 100 movies as you walk away for a month?

That is one use case but most importantly it can be potentially used in conjunction with Android client app to transcode on the fly using highly compressed and high quality mp4 format. MP4 decoding is supported on almost all streaming devices.

I made a fix to the SageTV core for how the transcode progress is calculated. SageTV was using the time from the status output of ffmpeg process output. It seems sometimes the ffmpeg time output does not increment. When this happens I changed the code so that it would use the current frame / fps. This seems to be working well. Where I was seeing this bug was when the transcoder was remuxing. It looks like this bug existed in the original SageTVTranscoder as well as my updated one.

I posted this to my Patreons first. If I do not hear any negative impact I will post the Sage.jar here and sumbit the fix to the main repository as a pull request.

Sweet!

Just took a quick look at your 1.2.2 (built from ffmpeg 4.4.2) you posted two weeks ago on your github.

SageTVTranscoder.exe -h encoder=h264_nvenc is showing all of the new presets and tunings:

I am going to start trying the new P1-P7 presets with my NVidia GeForce RTX 2070 Super.
