  • 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 (...)

  • De l’upload à la vidéo finale [version standalone]

    31 janvier 2010, par

    Le chemin d’un document audio ou vidéo dans SPIPMotion est divisé en trois étapes distinctes.
    Upload et récupération d’informations de la vidéo source
    Dans un premier temps, il est nécessaire de créer un article SPIP et de lui joindre le document vidéo "source".
    Au moment où ce document est joint à l’article, deux actions supplémentaires au comportement normal sont exécutées : La récupération des informations techniques des flux audio et video du fichier ; La génération d’une vignette : extraction d’une (...)

  • Unknown V4L2 pixel format equivalent for yuva420p with ffmpeg and v4l2loopback

    7 février 2019, par Kim

    I am trying to use filter_complex from ffmpeg to stich several video input together into one output.

    I use v4l2loopback to create a virtual video device :

    sudo modprobe v4l2loopback video_nr=90

    In this example, i first try with only one camera :

    v4l2-ctl --device=/dev/video0 --info gives the following output :

  -f v4l2 /dev/video90

    Which results in the following error :

    What I tried and didn’t work :

    • use -f h264 for the output, which ends in a av_interleaved_write_frame(): Invalid argument error

  • ffmpeg, v4l, snd_aloop ... sound asyncron (alsa buffer xrun)

    28 janvier 2019, par Tobias

    I’m trying to create a stream that automatically reloads random inputs. I would like to extend this to a database later.

    Each time ffmpeg finishes and starts again, so the input changes, the connection to the rtmp is interrupted briefly causing the whole connection breaks down. I then tried to separate audio and video, to send them to virtual devices and read from there again. Split the stream on virtual devices, reassemble them directly and send them to rtmp. If the input is then exchanged, the sending to the devices interrupts what does not bother the second ffmpeg. As soon as I stop sending to the devices the fps go very slowly (10 - 20 sec) from 25 to 0. Only then does the transmitter ffmpeg break the connection to the rtmp. The script which exchanges the inputs needs only one second. A practical test showed that everything works as desired.

    I can quite comfortably change the input while the second ffmpeg maintains the stream ...

    The joy did not last long. The sound is good 1 sec delayed. But sporadically. Sometimes everything works great. Sometimes the sound is offset.

    I wrote several scripts for this.

    Background :

    1. File is selected by random
    2. Media file is split and written to / dev / video0 (v4l loopback) and alsa default (snd_aloop loopback)
    3. Put the splits together again and stream them to a rtmp server

    Code that selects the input and sends to / dev / video0 and alsa default

    #!/bin/bash
    

    
cat /dev/null > log
    

    
while true;
    
do
    

    
  WATERMARK="watermark.png";
    
  dir='/homeXXXXXXXXXX/mix'
    
  file=`/bin/ls -1 "$dir" | sort --random-sort | head -1`
    
  DATEI=`readlink --canonicalize "$dir/$file"` # Converts to full path
    

    
if [ -z $DATEI ]
    
then
    
  echo "Keine Datei gefunden" >> log;
    
else
    
  START=$(date +%s);
    
  echo "Sende $DATEI" >> log;
    
  ffmpeg -re -y -i "$DATEI" -c:v libx264 -vf "fps=25,scale=640:480,setdar=4:3" -async 1 -pix_fmt yuv420p -preset ultrafast -map 0:0 -f v4l2 -vcodec rawvideo /dev/video0 -f alsa default
    
fi
    

    
DOKILL=`cat kill`;
    
if [ "$DOKILL" = "1"]
    
then
    
  break;
    
fi
    

    
done

    The sound is then absolutely unsynchronized ...

    Does anyone have any advice and can help me ?

  • Concatenating slideshows and normal videos causes audio bleeding

    28 janvier 2019, par Zurechtweiser

    I noticed audio bleeding with concatenated videos containing alternating slideshows and normal videos.

    My commands

    ffmpeg -y -ss 00:00:04.391 -to 00:02:17.171 -i "test.MP4" -r 60 -c:v libx264 -af afade=t=in:ss=0:d=1,afade=t=out:st='00\:02\:11.780':d=1 25.mp4
    
ffmpeg -y -i 25.mp4 -c copy -bsf:v h264_mp4toannexb -f mpegts 25f.ts
    

    
ffmpeg -y -loop 1 -i "test.JPG" -t 2 -f lavfi -i anullsrc=channel_layout=stereo:sample_rate=44100 -shortest -r 60 -c:v libx264 -c:a aac -pix_fmt yuv420p -vf scale=-2:1080,pad=width=1920:height=1080:x=240:y=0:color=black 26.mp4
    
ffmpeg -y -i 26.mp4 -c copy -bsf:v h264_mp4toannexb -f mpegts 26f.ts
    

    
ffmpeg -y -i "concat:25f.ts|26f.ts" -bsf:a aac_adtstoasc -movflags faststart -c copy "final.mp4"

    The rest of audio of test.MP4 bleeds into the beginning of the test.JPG-single frame slideshow.

    I presumed a different framerate to cause it, but adding -r 60 didn’t solve the issue.

    Also it seems that the video player interpretes the final video as a set of single videos, as whenever a "new" video shows up, it stutters slightly and loses framerate.

    How do I concat them without bleeding and create a final video without stuttering ?
