  • FFMPEG concat audio and videos produces only audio

    19 septembre 2019, par justaguytrynabuildawebsite

    Im trying to combine multiple video files with a single audio file. When using only videos without audio, it works fine but when adding a audio track to the beginning of the concat file i get the return below, and the output.mp4 becomes just audio with no video when previewing in browser.
    FFMPEG command

    ffmpeg -f concat -safe 0 -i /var/www/html/video_tool/edit/out/concat.txt -c copy -flags +global_header /var/www/html/video_tool/edit/out/output.mp4

  • Bash script doesn't read entire line

    4 octobre 2019, par Miguel Alatorre

    First off, I am in the early stages of learning bash shell scripting, so I apologize if I say / do anything that doesn’t make sense.

    Currently, I’m trying to have an SBC, a Khadas VIM3 specifically, run a python script to find and label faces in any given video from a local server. Currently, I need to reduce the frame rate and resolution of the video, which is where the bash script comes into play. I need to automate this process and thought I’d do it using a bash script and crontab.
    The file paths are found and output into a file from a separate script, and are read by the bash script. The problem comes when I try and call ffmpeg to use the file paths.

    The Code :

    pathFile="/home/khadas/Documents/paths"
    

    
while IFS= read -r line
    
do
    
        ffmpeg -i "$line" -vf scale=960:540 -y "$line"
    
        cp "$line" ./
    
done < $pathFile

    The resulting error :

    : No such file or directoryalRecognition/10/14-53.h264+/20-509-26-10-14-53.mp4
    
cp: cannot stat '/home/khadas/Downloads/FacialRecognition/10/14-53.h264+/20-509-26-10-14-53.mp4'$'\r': No such file or directory

    Example of the paths file (There will be hundreds of entries) :

    /home/khadas/Downloads/FacialRecognition/10/14-42.h264+/20-509-26-10-14-42.mp4
    
/home/khadas/Downloads/FacialRecognition/10/59-06.h264+/20-509-26-10-59-06.mp4
    
/home/khadas/Downloads/FacialRecognition/10/36-28.h264+/20-509-26-10-36-28.mp4
    
/home/khadas/Downloads/FacialRecognition/10/14-53.h264+/20-509-26-10-14-53.mp4

    When using a trimmed down version, the script works as expected. Could it be an issue with the length of the lines ? Any help is much appreciated.
