    If there is any other information I can give to solve the problem please let me know.

    


    I have tried the following lines, but none of them worked :

    


    ffmpeg -i "URL" -c copy output.mp4
ffmpeg -i "URL" -c copy -bsf:a aac_adtstoasc output.mp4


    


  • 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 Codemonkey

    I 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 top showing 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 help

      • 


    • nice -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 :

  • Unable to playback hardware encoded H.264 to RED5 server using FFmpeg

    26 février 2019, par Les

    I have a USB camera that is capable of H.264 on-board compression. I use the following FFmpeg command line to grab the encoded H.264 from the camera and put it in a ’flv’ container :

    ffmpeg -y -f dshow -vcodec h264 -i video="USB Camera" -vcodec copy -copyinkf -f flv c:\temp\test.flv

    This works as expected and I can view the video using VLC no problem. Following this principle I then attempt to stream to a RED5 server using the following command :

    ffmpeg -y -f dshow -vcodec h264 -i video="USB Camera" -vcodec copy -copyinkf -f flv rtmp://192.168.75.34/live/livestream

    The RED5 server detects the stream but I am unable to connect to it and view it using my basic Python program.

    If I do the same thing but use FFmpeg to carry out H.264 encoding of the default capture pin (MJPEG), it will stream correctly.

    I’m not sure if there is some flag in the command line that I might be missing ? Any help with this issue would be much appreciated.

    Here is the log output from the second FFmpeg command :

    C :\ffmpeg-latest-20190219\ffmpeg-static\bin>ffmpeg -y -f dshow -vcodec h264 -i video="USB Camera" -vcodec copy -copyinkf -f flv rtmp ://192.168.75.176/live/livestream"
