FFMPEG No such filter : 'format=nv12|vaapi,hwupload'
14 novembre 2022, par Devin DixonI'm on a AWS g4ad instance and I am trying to get hardware accelleration with the GPU to work. with ffmpeg. A base line test is this :


ffmpeg -y -vaapi_device /dev/dri/renderD128 -v info -thread_queue_size 10000 -i video.mp4 -c:v h264_vaapi -vf 'format=nv12|vaapi,hwupload' -crf 25 -tune zerolatency -g 120 -r 60 -pix_fmt yuv420p -preset faster -maxrate 14000k -bufsize 14000k -strict -2 -ar 44100 -b:a 128k -af aresample=async=1 -acodec aac file_out.mp4


The above works, GPU is installed and working correctly. In my actual use case, I am grabbing the screen from an X11Grab, which works without the GPU and normal libx264 but fails when I add try to use h264_vaapi. The command I use is below :


/usr/bin/ffmpeg -vaapi_device /dev/dri/renderD128 -y -v info -f x11grab -draw_mouse 0 -r 60 -s 1920x1080 -thread_queue_size 10000 -i :0.0+0,0 -f alsa -thread_queue_size 10000 -i plug:bsnoop -acodec aac -strict -2 -ar 44100 -b:a 128k -af aresample=async=1 -c:v h264_vaapi -vf 'format=nv12|vaapi,hwupload' -preset faster -maxrate 14000k -bufsize 14000k -pix_fmt yuv420p -r 60 -crf 25 -g 120 -tune zerolatency -f flv rtmp://[to_an_rtmp source]

And my output is this:

I see that is failing because No such filter : 'format=nv12|vaapi,hwupload', which I don't get when I run the other command. What am I doing wrong here ?

Saving frames as JPG with FFMPEG (Visual Studio / C++)
10 novembre 2022, par Diego SatizabalI am trying to save all frames from a mp4 video in separate JPG files, I have a code that runs and actually saves something to JPG files but files are not recognized as images and nothing is showing.


Below my full code, I am using Visual Studio 2022 in Windows 11 and FFMPEG 5.1. The function that saves the images is save_frame_as_jpeg which is actually an adaption from the code provided here but changing the use of avcodec_encode_video2 for avcodec_send_frame/avcodec_receive_packet as indicated in the documentation.


I am obiously doing something wrong but cannot quite find it, BTW, I know that a simple command (ffmpeg -i input.mp4 -vf fps=1 vid_%d.png) will do this but I am requiring to do it by code.


Any help is appreciated, thanks in advance !
