How can I increase the performance of this video watermarking call which seems to be only using 6% of my system's CPU ? Currently using ffmpeg
24 août 2023, par CodemonkeyI have a php script to add a watermark to an uploaded video, using ffmpeg


shell_exec("ffmpeg -y -i input.mp4 -i watermark.png -filter_complex $filter output.mp4")


The video is 36 seconds long, 33MB and 1080x1920, 24fps. The output video comes in at 8MB, scaled down to 540x960 with a PNG overlaid as a watermark.


The script takes about 3 seconds, averaging 320fps or so. For a one-off this would be ok, but I'm going to be processing hundreds/thousands of these at a time.


I have 128GB of ram and an EPYC 7502p (32cores/64threads), and both input and output files are on NVMe drives.


If I monitor
topshowing all my cores/threads in another window, with refresh delay set to a variety of things from 0.1 to 2 seconds, I'd guesstimate that this hits about 1/4 of my available threads, at about 25% utilisation each.

So it kind of feels like I COULD see a 16x speed increase if it hit all of them at 100%. That actually wouldn't be ideal, locking up the server of course, but when my CPU is sat at 99% idle 99% of the time, I feel it could do better - it'd be nice to see it hitting at least half the cores or utilising at least 50% of them when it does...


So, is there anything I can change with ffmpeg's config/build or the way I call it ? If this is as good as ffmpeg can do, are there better tools for the job ?


Thank you



EDIT :


A few things I've learnt since posting :


- 

-c:v libx264 -preset ultrafast- marginal helpnice -n -10- marginal help (changing to -20 is makes negligible difference)-c:a copy- significant help, which I found surprising








FPS up from 320 to 540 using those 3 combined. I still feel there should be significantly more gains somewhere though...



Here's the output from the original script, if it helps :

FFMPEG Pipeline Crash [closed]
17 août 2023, par Badgio10177I instantiate an ffmpeg pipeline within C++. No frames get streamed to the RTSP server and the pipeline crashes unexpectedly.


I have the following code :


#include <iostream>
#include <typeinfo>
#include "opencvmex.hpp"
#include 
#include 
#include "mex.h"
#include 
#include 
#include // Windows API for process enumeration
#include <opencv2></opencv2>core.hpp>

// Global variables
FILE* openPipeLine = NULL;

//////////////////////////////////////////////////////////////////////////////
// Exit function to execute when the mex function is cleared.
//////////////////////////////////////////////////////////////////////////////
void exitFcn()
{
 fflush(openPipeLine); // Clear out the pipeline.
 _pclose(openPipeLine); //Close the pipeline.
}

///////////////////////////////////////////////////////////////////////////
// Main entry point to a MEX function
///////////////////////////////////////////////////////////////////////////
void mexFunction(int nlhs, mxArray *plhs[], int nrhs, const mxArray *prhs[], int frameWidth, int frameHeight)
{
 // Use the appropriate namespace for OpenCV functions
 using namespace cv;

 Ptr<mat> inputFrame = ocvMxArrayToImage_uint8(prhs[0], true);
 Mat processedFrame = *inputFrame;

 // Check if FFMPEG process has been started
 if (!openPipeLine)
 {
 openPipeLine = _popen("ffmpeg -f rawvideo -r 10 -video_size 1280x720 -pixel_format bgr24 -i pipe: -vcodec libx264 -crf 25 -pix_fmt yuv420p -f rtsp rtsp://192.168.0.2:8554/mystream 2> log.txt", "wb");
 }

 // Write the frame data to the pipeline
 fwrite(processedFrame.data, 1, frameWidth * frameHeight * 3, openPipeLine);
 mexAtExit(exitFcn);
}



</mat></typeinfo></iostream>

The function is a Matlab Mex function. What is interesting is that there are certain times when the stream works and some times it just crashes. The log file for the ffmpeg process is the following :

Are there any parameters in my pipeline that are causing the process to crash ?

ffmpeg autorotate results in broken output when moving from cpu to gpu
16 août 2023, par user2290269Given an input file with a Display Matrix :


ffprobe -show_format -show_streams -print_format json -i rotated.mov

Using CPU-transcoding is resulting in a correctly rotated output file and exitcode 0 :


ffmpeg -autorotate 1 -y -i rotated.mov -f mp4 -vf scale=-2:360 -c:v libx264 -b:v 800K cpu.mp4

Using GPU-transcoding is resulting in a incorretly rotated output file and exitcode 0 :


ffmpeg -hwaccel cuda -hwaccel_output_format cuda -autorotate 1 -y -i rotated.mov -f mp4 -vf scale_cuda=-2:360 -c:v h264_nvenc -b:v 800K gpu.mp4

See the Display Matrix rotation information.
The GPU-File plays upside down, the CPU-File plays correctly.


Looks like (the default -autoroatate 1) is silently ignored for GPU-based transcoding. automatic insertion of filters fails silently. exitcode is 0 for gpu, too. but the output is actually broken, because it is upside down in playback.


Same is true for input having other rotations than -180°.


One (bad) way to solve, use complex filters :
When using complex filter with hwupload_cuda, the autorotate-filters get added correctly automatically.


ffmpeg -y -i rotated.mov -f mp4 -vf hwupload_cuda=device=0,scale_cuda=-2:360 -c:v h264_nvenc -b:v 800K gpu-complexfilter.mp4

When going into scale_cuda directly there is an error message and exitcode !=0.


ffmpeg -y -loglevel debug -i rotated.mov -f mp4 -vf scale_cuda=-2:360 -c:v h264_nvenc -b:v 800K gpu-error.mp4

Impossible to convert between the formats supported by the filter 'hflip' and the filter 'auto_scale_0'
[vf#0:0 @ 0000026723318540] Error reinitializing filters!
Failed to inject frame into filter network: Function not implemented
Error while filtering: Function not implemented


Using complex filters is not a good solution, because it disables automatic filter graph filter-adding and -mapping, which is very useful for e.g. -f HLS.


So is there a way to keep complex filters away and get correct output or exitcode !=0 indicating a broken output for any given input-file coming as a file-upload from the internet ?
