  • stream_loop generate a big size video [FFMPEG]

    26 mars 2021, par Mouaad Abdelghafour AITALI

    I'm trying to loop a short video for e.g. 190 time to match the audio length, I use the following code :

    


    -y -stream_loop  190  -i input.mp4 -c copy output.mp4


    


    The command above works, but it generates video with huge size for video with 3min the size is 885 MB

    


    2021-03-25 23:52:30.445 5687-6253/maa.abc.music_maker D/XXX: LOOPING VIDEO SIZE ===> 885.845MB


    


    Or there's any way I can loop the video to match the audio length without using -stream_loop

    


  • Batch process audio files and image files to create movie files by matching multiple wildcard values

    29 septembre 2022, par psychaudio

    I'm attempting to batch-process audio and image files to create video files using a Shell script with FFmpeg.

    


      

    1. The ffmpeg script works in Terminal :
    2. 


    


    ffmpeg -loop 1 -i image.png -i audio.wav -c:v libx264 -tune stillimage -c:a aac -b:a 192k -pix_fmt yuv420p -shortest output.mp4


    


      

    1. A nested for loop with wildcards works as a batch script :
    2. 


    


    #!/bin/sh
for img in *.png; do
    for wav in *.wav; do
        ffmpeg -loop 1 -i $img -i $wav -c:v libx264 -tune stillimage -c:a aac -b:a 192k -pix_fmt yuv420p -shortest ../mb/$img.mp4
    done
done


    


    The only problem here is that it creates more combinations than I need. I'd like to be able to match wildcard values and only mix those together. I'd like to be able to prepare the filenames to match in advance to make this easier : For example, only match 1.png with 1.wav to make 1.mp4, 2.png with 2.wav to make 2.mp4 and so on. I'm able to modify the script to match the wildcards in a Regex, but I'm not sure if there is a way to then execute the logic above. Here is what I am attempting :

    


    #!/bin/sh
img=*.png
wav=*.wav

if [[ ${img%.*} == ${wav%.*} ]];
    then
        ffmpeg -loop 1 -i $img -i $wav -c:v libx264 -tune stillimage -c:a aac -b:a 192k -pix_fmt yuv420p -shortest $img.mp4;
    else
        echo "Failure"
    fi


    


    This begins by overwriting the image files, so it does not appear to work as planned. Is there a simpler way to do this ? Perhaps looping through images 1..5 in one folder and audio files 1..5 in another ?

    


    Thanks for any insights, and happy to provide more context (very new to this, so still learning).

    


  • Trying to use the arcade library on Python3 with Debian 10 errors with pyglet_ffmpeg

    30 mars 2020, par Colin

    I’ve been trying to use the arcade library this morning with python3 but keep getting nothing but errors.

    My environment is Debian 10 (buster)

    I checked first to ensure I have python 3 installed, this confirmed as Python 3.7.3

    I double checked (according to the arcade library website arcade linux installation instructions and ran the install for python3 to make sure that pip and the required libraries were installed.

    I then ran the command to install the library

    sudo pip3 install arcade

    And to test it, copied and pasted the happy_face.py example. However when I tried to run it I got a slew of errors. This seems to be directly related to the arcade installation and if I just run a python script (test.py) with just one line

    import arcade

    At the terminal with

    python3 test.py

    I get the following errors

    I have used the following terminal command to identify the version of OpenGL installed

    glxinfo | grep "OpenGL version"

    Which returned

    OpenGL version string : 3.3 (Compatibility Profile) Mesa 18.3.6

    I have also tried the terminal command

    sudo pip3 install pyglet-ffmpeg

    Which returns

    Requirement already satisfied : pyglet-ffmpeg in
    /usr/local/lib/python3.7/dist-packages (0.1.4)

    Requirement already satisfied : pyglet>=1.4.0a1 in
    /usr/local/lib/python3.7/dist-packages (from pyglet-ffmpeg) (1.5.0)

    Requirement already satisfied : future in
    /usr/local/lib/python3.7/dist-packages (from
    pyglet>=1.4.0a1->pyglet-ffmpeg) (0.18.2)

    Any assistance would be appreciated. I’ve tried to be as concise as I can, but if more information is required, I’ll gladly supply it.
