  • Unable to FW/RW video after remuxing multiple mpeg-ts to mp4

    21 juillet 2022, par Jona

    I have written custom code to concat multiple mpeg-ts files into an mp4 video file. I've used as reference the remuxing code sample.

    


    I'm having issues with the final output. I'm unable to fast-forward or rewind as the video looses it's information and plays the same frame till the end. But if i play from the beginning it plays fine.

    


    I compared using ffprobe my custom code remuxer results to that of using the following terminal command :

    


    ffmpeg -i "concat:input1.ts|input2.ts|input3.ts" -c copy output.mp4


    


    To my surprise, the videos look almost identical but I'm noticing some differences in the reported distance and keyframe values. I also did a hex comparison and see minor differences at the end of the file which tells me I've muxed the frames correctly. What could I be missing ? Any tips or ideas would be really helpful !

  • Unable to scrub video after remuxing multiple mpeg-ts to mp4

    21 juillet 2022, par Jona

    I have written custom code to concat multiple mpeg-ts files into an mp4 video file. I've used as reference the remuxing code sample.

    


    I'm having issues with the final output. I'm unable to scrub the video on QuickTime. The final output seems to be missing something.

  • apply ffmpeg to many files

    30 juillet 2015, par puchu

    I have written simple script :

    #!/bin/bash
    
find . -name "*.m4a" | while read filename;
    
do
    
    new_filename=$(echo "$filename" | sed "s/^\(.*\)m4a$/\1flac/g");
    
    if [ ! -f "$new_filename" ]
    
    then
    
            #ffmpeg -i "$filename" -acodec flac "$new_filename" > /dev/null 2>&1;
    
            #wait $!;
    
            echo "$filename";
    
            echo "$new_filename";
    
    fi
    
done

    it outputs correct result :

    ./Equilibrium, ALAC [GER] viking.folk/2003 - Demo 2003, ALAC/04 - Met.m4a
    
./Equilibrium, ALAC [GER] viking.folk/2003 - Demo 2003, ALAC/04 - Met.flac
    
./Equilibrium, ALAC [GER] viking.folk/2003 - Demo 2003, ALAC/02 - Nach Dem Winter.m4a
    
./Equilibrium, ALAC [GER] viking.folk/2003 - Demo 2003, ALAC/02 - Nach Dem Winter.flac

    if uncomment ffmpeg and wait :

    ./Equilibrium, ALAC [GER] viking.folk/2003 - Demo 2003, ALAC/04 - Met.m4a
    
./Equilibrium, ALAC [GER] viking.folk/2003 - Demo 2003, ALAC/04 - Met.flac
    
uilibrium, ALAC [GER] viking.folk/2003 - Demo 2003, ALAC/02 - Nach Dem Winter.m4a
    
uilibrium, ALAC [GER] viking.folk/2003 - Demo 2003, ALAC/02 - Nach Dem Winter.flac

    And no flacs has been done !

    PS

    #!/bin/bash
    
find . -name "*.m4a" | while read filename;
    
do
    
    new_filename=$(echo "$filename" | sed "s/^\(.*\)m4a$/\1flac/g");
    
    if [ ! -f "$new_filename" ]
    
    then
    
            ffmpeg -i "$filename" -acodec flac "$new_filename";
    
            echo "$filename";
    
            echo "$new_filename";
    
    fi
    
    sleep 5;
    
done

    1) encode start but suddenly stop with no error messages

    2) encode couldn’t start because of "uilibrium" instead of "./Equilibrium"

    3) = 1)

    4) = 2)

    ...

    last) correctly
