HEVCQSV : GPU load decreasing (due to a specific option) #932

Bigsausage64 · 2018-09-18T14:59:15Z

Hi,

First, a huge "thank you" for the work you do on the script !!

It works for me but not really as expected : I've noticed something really strange when using HEVCQSV (or H264QSV). Conversion starts normally, my first GPU (Intel HD630) is used at 100% and my second GPU (AMD RX Vega M GL) is loaded around 25%.

Then, depending on which option I set in the autoprocess.ini, the GPU load for both GPUs decreases consistently until reaching only few %. Obviously, this makes conversion really long, much longer than when GPUs are both used to the max.

When I use MyFFMPEG (a GUI for FFMPEG), both GPUs are used to the max (100% for Intel and 25% for AMD) until the end of the conversion.

So I decided to troubleshoot by comparing the command line used by MyFFMPEG and MP4 Automator.

Here is the commande line that is created by MyFFMPEG:

ffmpeg -probesize 50M -analyzeduration 100M -hwaccel dxva2 -i "input.mkv" -map 0:0 -map 0:1 -c:a aac -strict -2 -async 1 -c:v hevc_qsv -load_plugin hevc_hw -b:v 14307.84k -maxrate 28615.68k -bufsize 28615.68k -s 1920x1080 -aspect 16:9 -pix_fmt yuv420p10le -vsync 0 -preset fast -x265-params profile=main10:me=hex:qcomp=0.5:scenecut=40:bframes=4:rc-lookahead=40:min-keyint=24:keyint=240 -sws_flags fast_bilinear -qmin 3 -qmax 51 -vtag hvc1 -metadata creation_time=now -sn -y "output.mp4"

Here is my autoprocess.ini :

preopts = -loglevel,debug,-probesize,50000,-analyzeduration,100000m

Here is the command line generated by MP4 Automator:

ffmpeg -loglevel debug -probesize 50000 -analyzeduration 100000m -hwaccel dxva2 -i "input.mkv" -vcodec hevc_qsv -map 0:0 -vb 7470k -tag:v hvc1 -c:a:0 copy -map 0:1 -metadata:s:a:0 language=eng -disposition:a:0 default -f mp4 -threads 0 -load_plugin hevc_hw -maxrate 30000.00k -bufsize 30000.00k -pix_fmt yuv420p10le -vsync 0 -preset fast -x265-params profile=main10:me=hex:qcomp=0.5:scenecut=40:bframes=4:rc-lookahead=40:min-keyint=24:keyint=240 -sws_flags fast_bilinear -qmin 3 -qmax 51 -y "output.mp4"

I discovered that if I manually remove the "-disposition:a:0 default" and manually launch the command, everything works fine from the GPU perspective.

I've tried to change every audio settings in autoprocess.ini to see if that makes any change but the "-disposition:x:0 xxxxxxxx" settings is always generated in the command line and consequently I always encounter the decrease in GPU load.

Is it a bug ? Am I doing something wrong ? I'd really like to be able to use my GPUs to encode files (I'm ok for quality loss, and so happy with the silence and the speed compared to pure CPU encoding......)

I hope you'll be able to help me. I've searched google completely two times before asking this :-D

Last but not least, I know FFMPEG supports AMD AMF encoder, would it be a lot of work to have it implemented in your script ? Thanks again

I tried to assign manully the GPU, I tried with many different input files, I tried the following hwaccel dxva2, d3dv11, qsv.......always the same : GPU load decreasing or worse, encoding not even starting.

I did not mention previously, my machine is a nuc8i7hnk running Windows 10 64bit with the latest os and drivers updates, version 4.0.2 static of ffmpeg from zeranoe.

I also did not mention that, natively, the script doesn't work if I only set HEVCQSV as video codec. I had to add the "load_plugin hevc" for it to work.

Then I encountered the GPU load issue, that's how I came to compare MyFFMPEG and MP4 automator command lines.......I can provide video files, logs.

Thanks

Bigsausage64 · 2018-09-25T07:24:42Z

Maybe you can just tell me where I need to comment your code, so Il get rid of the settings ?

mdhiggins · 2018-10-12T11:52:28Z

Not sure why disposition would cause an issue, but if you need to disable that feature you can knock it out by commenting out lines 111 and 112 in converter/avcodecs.py

        if 'disposition' in safe:
            optlist.extend(['-disposition:a:' + stream, str(safe['disposition'])])

mdhiggins · 2018-10-12T11:52:51Z

I suspect that's probably an FFMPEG bug and would advise trying some different builds of FFMPEG and see if that persists

Bigsausage64 · 2018-10-12T11:55:46Z

Hey !

I'll try with another FFMPEG version and worst case, I'll comment out the lines.

THANK YOU very much for your feedback !!

mdhiggins · 2018-10-12T11:56:33Z

No problem, let me know what the final result is

Bigsausage64 · 2018-10-12T22:01:30Z

Hi,

Just been testing.

I started by commenting line 111 & 112 in converter/avcodecs.py : this did not remove the "disposition" option in the FFMPEG commandline and obviously the problem is still there.

Then I tried with FFMPEG static 3.4.2. Same result ?! no luck

Bigsausage64 · 2018-10-12T22:16:37Z

I've just tried the 32 bit version of both 3.4.2 and 4.02 of FFMPEG and the result is the same. Not working.

Any other suggestions ?

mdhiggins · 2018-10-12T23:07:39Z

Hm I mean that's definitely where that FFMPEG entry comes from. I see you're on windows. Sometimes you have to delete the .pyc files that are created for those changes to take affect

Also for copied audio codecs the disposition may be applied as well, you may need to also comment out lines 480 and 481 which should look essentially identical to the ones you commented out earlier

Bigsausage64 · 2018-10-13T08:34:02Z

Okay........it's getting even weirder !

Commenting out line 480 and 481 made the "disposition" option disappear in the command line but during the test using manual.py, the "GPU load" issue I described above is still occuring.................

Then I stopped the script, checked the logs, found the command line that was generated and launched it manually (outside any script), the issue did not occur.

I defintely think there is something wrong with the script (no offense).

Any other suggestions to get a workaround or even a fix ?

In any case, thank you for your help !!!!

mdhiggins · 2018-10-13T13:03:29Z

Can you post the full command that's generated? I wonder if its maybe an issue with the threads option?

2018-10-13 15:17:21 - MANUAL - INFO - Starting conversion.

Here I interrupted conversion because the issue occured.

FYI, it always starts after 2% of the conversion and really start to decrease after 3 or 4 %

mdhiggins · 2018-10-13T13:29:44Z

Out of curiosity, when using MyFFMPEG vs the script, are you using the exact same read and write destination drives? The fact that it throttles after a certain point sounds like there's a bottleneck somewhere and often that occurs when memory is saturated and it becomes limited by HDD write speeds. If you were by chance using a different drive for MyFFMPEG that may cause it.

mdhiggins · 2018-10-13T13:32:30Z

And the next step I would try is taking the command generated by the script and running that manually with isolated changes until you find what seems to trigger the fix. I wonder if trying to remove the 'threads' parameter might make any difference. Its set to 0 which should be auto but maybe just removing the flag all together?

Bigsausage64 · 2018-10-13T13:33:43Z

My final objective is that my current machine will convert files stored in a NAS folder (source and target will be in the same folder, but remote).

But so far, all my tests are made locally : source and target are stored in a local drive (Samsung 960 Evo 1 Tb - NVME PCIE4x SSD).

I have also 16 Gb of RAM. Running Windows 10 64 bit (stable not insider or whatever...)

mdhiggins · 2018-10-13T13:36:07Z

Also, if you run the command generated by the script manually in command prompt does that perform the same way?

Another idea would be to run things and keep an eye on any obvious performance bottlenecks using resource monitor in windows that might explain why things are throttling

Bigsausage64 · 2018-10-13T13:45:25Z

Taking command line from the logs and removing "threads" option :

C:\Script\ffmpeg\ffmpegRadarr.exe -loglevel debug -probesize 50000 -analyzeduration 100000 -hwaccel dxva2 -i "C:\Script\Test\African Cats (2011) (1080p BluRay x265 Silence).mkv" -vcodec hevc_qsv -map 0:0 -vb 7470k -tag:v hvc1 -c:a:0 copy -map 0:1 -metadata:s:a:0 language=eng -f mp4 -load_plugin hevc_hw -maxrate 30000.00k -pix_fmt yuv420p10le -preset fast -sws_flags fast_bilinear -qmin 3 -qmax 51 -y "C:\Script\Test\African Cats (2011) (1080p BluRay x265 Silence).mp4"

FFMPEG stops converting after few frames...........

mdhiggins · 2018-10-13T13:49:36Z

Hm, so here's a breakdown of the differences between the two commands from your original post

-probesize 50M : -probesize 50000
--- : -loglevel debug
-analyzeduration 100M: -analyzeduration 100000m
-b:v 14307.84k : -vb 7470k
-strict -2 : ---
-async 1 : ---
-c:a aac : -c:a:0 copy
--- : -f mp4
--- : -threads 0
-maxrate 28615.68k : -maxrate 30000.00k
-bufsize 28615.68k : -bufsize 30000.00k
--- : -disposition:a:0 default 
--- : -metadata:s:a:0 language=eng
-s 1920x1080 : ---
-sn : ---
-s 1920x1080 -aspect 16:9 -metadata creation_time=now: ---

Things with --- are absent, things to the left of the : are from myFFMPEG, right is SMA

If we filter out stupid things like metadata inconsistencies here is the list of possible performance problems

-probesize 50M : -probesize 50000
--- : -loglevel debug
-analyzeduration 100M: -analyzeduration 100000m
-b:v 14307.84k : -vb 7470k
-strict -2 : ---
-async 1 : ---
--- : -f mp4
--- : -threads 0

There's a big difference in the setting for analyzeduration and probesize, I wonder if maybe that's the culprit? I doubt debug level logging would be the issue but sometimes if logging is very aggressive it can cause performance hits. The bitrate variations probably aren't the issue. Not sure about strict and async

Bigsausage64 · 2018-10-13T13:52:38Z

I tested then with the same command line as the one generated by the script but I launched it manually in a DOS command :

C:\Script\ffmpeg\ffmpegRadarr.exe -loglevel debug -probesize 50000 -analyzeduration 100000 -hwaccel dxva2 -i "C:\Script\Test\African Cats (2011) (1080p BluRay x265 Silence).mkv" -vcodec hevc_qsv -map 0:0 -vb 7470k -tag:v hvc1 -c:a:0 copy -map 0:1 -metadata:s:a:0 language=eng -f mp4 -threads 0 -load_plugin hevc_hw -maxrate 30000.00k -pix_fmt yuv420p10le -preset fast -sws_flags fast_bilinear -qmin 3 -qmax 51 -y "C:\Script\Test\African Cats (2011) (1080p BluRay x265 Silence).mp4"

And it works fine !!!!!

mdhiggins · 2018-10-13T14:01:11Z

Hm that's very strange, so the command itself is fine when running from command prompt?

Bigsausage64 · 2018-10-13T14:06:26Z

Correct......threads option is not faulty 🤔

To be honest, I don't even know the meaning of the multiple options, my only goal was for the script to generate the same command line as MyFFMPEG, which I know, works perfectly.....

We can get rid of every options as long as it converts 😉

mdhiggins · 2018-10-13T14:22:51Z

Hm, very strange and I'm not sure why Popen / Python would create the bottleneck

Try going to converter/ffmpeg.py to line 379-380 and changing shell=False to shell=True

Bigsausage64 · 2018-10-13T14:47:47Z

File start converting but GPU load decrease....

It doesn't work even with shell=True in converter/ffmpeg.py on line 379 :'(

PS : I removed the converter/ffmpeg.pyc file but how can I be sure the change was taken into account ?

mdhiggins · 2018-10-13T15:15:57Z

Out of curiosity, could you try running on 64 bit python3 instead of python27 (not sure if you're on 64 bit or not but I would try 64)

Bigsausage64 · 2018-10-13T16:02:48Z

YESSSSSSSSSSSSSSSSSSSSSSSSS Thank you so much !!! It works fine with Python 3 64 bit

mdhiggins · 2018-10-13T16:04:38Z

Good news
Guess we can close this issue haha, glad its working

Bigsausage64 · 2018-10-13T16:05:22Z

Fantastic !! Thank you so much

Bigsausage64 · 2018-10-13T17:50:41Z

You're the man !!!!!!!!!!

Plex transcoding a 4k files for sync + 1 conversion with your script both stored on NAS and look at that :

You made my day
