  • 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.

  • Support audio et vidéo HTML5

    10 avril 2011

    MediaSPIP utilise les balises HTML5 video et audio pour la lecture de documents multimedia en profitant des dernières innovations du W3C supportées par les navigateurs modernes.
    Pour les navigateurs plus anciens, le lecteur flash Flowplayer est utilisé.
    Le lecteur HTML5 utilisé a été spécifiquement créé pour MediaSPIP : il est complètement modifiable graphiquement pour correspondre à un thème choisi.
    Ces technologies permettent de distribuer vidéo et son à la fois sur des ordinateurs conventionnels (...)

  • Why is the filesize different when swapping audio tracks using ffmeg ?

    20 août 2021, par Brian

    I have a movie that I have encoded using Handbrake on a Mac a long time ago. When I encoded the movie, I put the stereo audio as track 1 and the 5.1 audio as track 2. The starting filesize is 853,320,914 bytes. Below is the data from ffprobe.

Unsupported codec with id 100359 for input stream 3


    


    My goal is to swap the stereo audio track with the 5.1 audio track and make the 5.1 audio track the default without having to reencode. To do this, I used the following command :

    


    ffmpeg -i "Annabelle - Comes Home (2019)/Annabelle - Comes Home (2019)_old.m4v" -map 0:v:0 -map 0:a:1 -map 0:a:0 -disposition:a:0 default -disposition:a:1 none -c copy "Annabelle - Comes Home (2019)/Annabelle - Comes Home (2019).m4v"

    


    Everything works as it should, I think anyways as I didn't get any errors...

    What I don't understand is why is the file size different ? The resulting file is larger at 854,292,790 bytes. Shouldn't the file sizes be the same since I literally just swapped tracks 0 and 1 ?

    


  • How to combine multiple video blobs in js without gap ?

    5 septembre 2021, par Pouria Moosavi

    I have an array of urls. I download them with fetch and then get blob from each response with await res.blob(). I need to concat all these blobs together to make a full video out of it, I tried to push each blob into an array and make a file new File(blobArray, "test") but the result has a gap between each blob.

    


    I've tried to save each blob as a separate file and concat them with ffmpeg -f concat -safe 0 -i text -c copy out3.mp4 and the result was perfect. So I know that my blobs are correct and the problem is how I am combining them together.

    


    This is my full code :

    Unfortunately links will expire soon but I think it is obvious what I am trying to do.

    


    So Is there any way to cancat blobs in JS and create the entire video smoothly like the ffmpeg does ?

    


    Thanks in advance.

    


  • Forcing ffmpeg to capture unreliable ALSA audio stream

    6 février 2015, par Peter Becich

    I am attempting to transfer some old Video 8 tapes to my computer, though an EasyCap USB stick and the motherboard’s sound line-in, on Ubuntu. I believe the arguments are correctly laid out below to capture from two independent streams, and encode them both into the output MP4 file.

    ffmpeg’s detection of the ALSA stream is seemingly goofed up by the inconsistencies of the tape. In the failure case, only short blips of the tapes audio exist in the output MP4. The audio bitrate of the output file is less than 10 kbps, averaged out across the whole file. The output video seems to be fine, even though the low frames-per-second in the failure case log below.

    The audio and video streams can be captured fine for short amounts of time before a source error occurs ; this provides the success case log. The failure case log was created by intentionally making an error in the source streams — turning on the camera makes a brief noisy signal.

    Is there a setting that needs to be forced to keep ffmpeg recording the audio stream, even when the tape is blank or noisy ?

    Could it be that the libfdk_aac audio encoder is tripped up by the low quality source ?

    The relevant line ; rawvideo stream is piped to this in script at bottom :

    ffmpeg -pixel_format uyvy422 -s:v 720x480 -framerate 29.97 -f rawvideo \
    
-i $PIPE  -f alsa -i hw:0,0 -vf scale=w=720:h=540 -vcodec libx264 \
    
-preset ultrafast -shortest -c:a libfdk_aac -b:a 128k -af pan=1:c0=c0  \
    
-ar 96000 $OUTFILE

    The ar argument was one attempt to force recording.

    ffmpeg log file for (short-lived) success ; high frames-per-second captured :
