  • How to set audio speed to 0.3 in Ffmpeg ?

    15 septembre 2020, par WebDiva

    I am using ffmpeg to set the audio and video speed to 0.3x. I can set the video speed but can't set the audio speed to 0.3x. Here is the command

    


    ffmpeg -y -i video.mp4 -vf "setpts=PTS/0.3" -r 50 -c:v mpeg4 -b:v 1500k -af "atempo=0.3" output.mp4


    


    It says :

    


    Value 0.300000 for parameter 'tempo' out of range [0.5 - 100]


    


    Is there a workaround ? Any help will be appreciated. Regards.

    


  • How can I speed up this side by side video stitch in FFMPEG

    21 octobre 2020, par ianf

    I have two videos the same size and pixel format (about 240x360) left and right that I want to stitch together.

    


    I'm using :

    


    ffmpeg -i left.mp4 -i right.mp4  -filter_complex "[0:v][1:v]hstack=inputs=2:shortest=1[v]; [0:a][1:a]amerge[a]" -map "[v]" -map "[a]" -ac 2 -shortest -y output.mp4


    


    which takes about 15 seconds on a 3 core machine. I see x1.25 on the conversion line.

    


    I know this isnt too bad, but any speed up I can make is going to help a lot as its in heavy use.

    


    Any ideas how I can improve this ?

    -y -i "+mInputPath+" -vf -s 640x480 -threads 5 -preset ultrafast -strict -2 "+mOutputPath.getAbsolutePath();

    Does anyone know how to increase speed ?
