  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • ffplay - route incoming audio stream to specific channels / convert channel layout

    7 septembre 2022, par miasma

    i need to play a mp3 stream (stereo) via ffplay and send it to specific output channels on my multichannel audio hardware.

    


    stream (stereo) -> output 3 & 4
while doing that the unused channels should stay silent, as i want to send to them from other instances of ffplay.

    


    how would i go about to do that ?

    


    i already tried a lot of different approaches without luck, mostly based on this :

    


    ffplay -i http://blablabla -af 'channelmap=map=0-2|1-3' -nodisp


    


    as well as

    


    ffplay -i http://blablabla -af 'channelmap=map=0-2|1-3=channel_layout=6.0'


    


    thank you for any help, i'm slowly going crazy digging through the manuals and trying out variations of the same command for hours …
😵‍💫

    


    ps : i'm running ffplay 5.1.1 on mac os 12.5.1 on m1max

    


  • ffmpeg timelimit error

    18 janvier 2013, par user1991209

    I am streaming from an I.P. address and converting the streams into .ts files. I am trying to apply a time limit using -t 00:0015, just for making sure everything works.

    In ffmpeg the time displayed is negative (-26 :-30 :-41) so it doesn't stop. I imagine it will stop after 26 hours 30 min and 56 secs (the countdown from -26 :-30 :-41 plus 00:00:15) but I've never let it run that long.

    Why is this occurring and how can I fix this ?

    Example :

    frame=   58 fps= 56 q=-1.0 size=    1288kB time=-26:-30:-41.-20 bitrate=  -0.1kbits/s    
    
frame=   74 fps= 48 q=-1.0 size=    1658kB time=-26:-30:-40.-66 bitrate=  -0.1kbits/s    
    
frame=   89 fps= 43 q=-1.0 size=    2101kB time=-26:-30:-40.-16 bitrate=  -0.2kbits/s    
    
frame=  107 fps= 41 q=-1.0 size=    2516kB time=-26:-30:-39.-56 bitrate=  -0.2kbits/s    
    
frame=  122 fps= 39 q=-1.0 size=    2879kB time=-26:-30:-39.-6 bitrate=  -0.2kbits/s

  • Best options for producing 2160p videos with ffmpeg

    15 janvier 2016, par Cotta1000

    I’ve been using ffmpeg to convert a stream of CGI frames into a video for uploading to Youtube, but the quality is always very poor even when the raw frames are 4096x2048 or 8192x4096. The Youtube setting always defaults to 360p. I’ve spent hours Googling for help with this, but the best I could find was a way to get a list of available -pix_fmt options.
    I’ve tried command line options such as the following two examples, both of which produce the same poor results in spite of the differences in parameters :

    ffmpeg -framerate 30 -i "C :\test360\Test 360_%%06d.bmp" -an -c:v libx264 -r 30 -pix_fmt yuv420p -preset veryfast -crf 18 test.mp4

    ffmpeg -framerate 30 -i "C :\test360\Test 360_%%06d.bmp" -an -c:v libx264 -r 30 -pix_fmt gbrap16le -preset slow -crf 18 test.mp4
