  • HTML5 audio and video support

    13 avril 2011, par

    MediaSPIP uses HTML5 video and audio tags to play multimedia files, taking advantage of the latest W3C innovations supported by modern browsers.
    The MediaSPIP player used has been created specifically for MediaSPIP and can be easily adapted to fit in with a specific theme.

  • 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 (...)

  • 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.

  • Is there a way to pipe input video into ffmpeg ?

    31 janvier 2019, par Joe Williams

    ffmpeg -f avfoundation -i "1:0" -vf "crop=1920:1080:0:0" -pix_fmt yuv420p -y -r 30 -c:a aac -b:a 128k -f flv rtmp://RTMP_SERVER:RTMP_PORT/STREAM_KEY

    Hello guys, the above command works pretty well. It records the audio/video of the computer. But what I want to do is pipe a repeating video or image(png/jpeg/gif), so that there is no live video feed from the computer, but just the image on the stream with the audio.

    How would you go about doing this ?

    Also, if you know any programming interfaces that can do this same thing, please give suggestions. Because I would rather not use a CLI.

  • 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 ?

  • FFmpeg settings for Apple TV 4K

    22 janvier 2019, par Igor

    What settings I should use with FFmpeg to create H.264 4K video compatible with Apple TV 4K ?

    iTunes doesn’t import 4K videos which I created with default settings of FFmpeg, libx264, -crf 18, 3840 x 2160, 30p

    No problem with 1920 x 1080, 30p videos.
