  • FFMPEG RGB Lossless conversion video

    29 août 2017, par DCDCDC

    I have been experiencing difficulty in finding many answers with FFMPEG documentation, forums and here.
    What I am trying to do is a compress a screen capture video but with just RGB data.
    The steps I am currently taking are ;

    ffmpeg -f avfoundation -pix_fmt 0rgb -r "30" -i "1" -vcodec libx264rgb -pix_fmt rgb24 -crf 0 -t 25 -q 0 -y ~/Desktop/RGB.mkv

    This captures the screen on my mac. To the best of my knowledge, this creates a lossless file and I have compared screen shots that confirm this.
    The next step is where I think I have an issue.
    Because I want to run the compression on raw RGB data I need to convert the MKV to an RGB file ;

    ffmpeg -i ~/Desktop/RGB.mkv -c:v rawvideo -pix_fmt rgb24 -crf 0 -ss 00:00:03 -to 00:02:01 -q 0 -y ~/Desktop/out.rgb

    But here I have pixel variance. My guess is there is a RGB-YUV-RGB conversion happening somewhere but I am not smart enough to work out where.
    If any of you can help I would forever grateful.

    Here is a picture of the two stills side by side that shows the differences ;

    If you need anything more I can post it also.

  • Is there a way to speed up the FFmpeg command '-filter_complex' ?

    31 août 2017, par Emma

    When using ffmpeg to re-encode videos, this is pretty fast. But when using the -filter_complex command the process slows down to real time. Is this process bound to the CPU or GPU ? Does anyone know if there is any way to speed this up using the GPU ?

    The full call is the following :

    ffmpeg.exe
    
-i video_0_0.mp4 -i video_0_1.mp4 -i video_0_2.mp4 -i video_0_3.mp4 
    
-filter_complex 
    
    "color=c=black:size=1920x1080 [base]; 
    
    [0:v] setpts=PTS-STARTPTS, scale=960x540 [upperleft]; 
    
    [1:v] setpts=PTS-STARTPTS, scale=960x540 [upperright]; 
    
    [2:v] setpts=PTS-STARTPTS, scale=960x540 [lowerleft]; 
    
    [3:v] setpts=PTS-STARTPTS, scale=960x540 [lowerright]; 
    
    [base][upperleft] overlay=shortest=1 [tmp1]; 
    
    [tmp1][upperright] overlay=shortest=1:x=960 [tmp2]; 
    
    [tmp2][lowerleft] overlay=shortest=1:y=540 [tmp3]; 
    
    [tmp3][lowerright] overlay=shortest=1:x=960:y=540" 
    
-q 4 -y
    
"test.mp4"

    output of the command :

    ffmpeg.exe -i video_0_0.mp4 -i video_0_1.mp4 -i video_0_2.mp4 -i video_0_3.mp4 -filter_complex "color=c=black:size=1920x1080 [base]; [0:v] setpts=PTS-STARTPTS, scale=960x540 [upperleft]; [1:v] setpts=PTS-STARTPTS, scale=960x540 [upperright]; [2:v] setpts=PTS-STARTPTS, scale=960x540 [lowerleft]; [3:v] setpts=PTS-STARTPTS, scale=960x540 [lowerright]; [base][upperleft] overlay=shortest=1 [tmp1]; [tmp1][upperright] overlay=shortest=1:x=960 [tmp2]; [tmp2][lowerleft] overlay=shortest=1:y=540 [tmp3]; [tmp3][lowerright] overlay=shortest=1:x=960:y=540" -q 4 -y "test.mp4"

  • ffmpeg concat with video using image background

    16 janvier 2018, par ant-C

    Ffmpeg does not concat the media files correctly using various testing. One of the videos is a .mp4 (h264 codec) video generated previously using a .mp3 and a jpeg background. I’ve tried testing with various flags, closest I’ve gotten is below for the final output.

    My main issue is the final video with the current test, the audio is about 3 seconds delayed once the two videos are stitched together.

    Here are all the files I’m using :

    Input Files :
