  • 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 (...)

  • 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.
    For older browsers the Flowplayer flash fallback is used.
    MediaSPIP allows for media playback on major mobile platforms with the above (...)

  • FFMPEG No encoder found for codec id 8

    3 septembre 2018, par raspiboele

    I’m using a Raspberry Pi to restreem a (https) .m3u8 stream, to a local MJPEG-stream with FFMPEG.
    Becaus I have a Nest Cam / Nest Hello and I want to import that stream into my Fibaro Homecenter (Smarthome Basestation), but the Fibaro Homecenter only eats the MJPEG format. So I made a Raspberry Pi with FFMPEG to do the trick.

    This is my /etc/ffserver.conf file :

    HTTPPort 8090
    

    
HTTPBindAddress 0.0.0.0
    

    
MaxHTTPConnections 2000
    

    
MaxClients 1000
    

    
MaxBandwidth 1000

    It is frutstrating me, because I’m looking for a solution for three days now. I can’t even find a list of encoders and the coresponding ID’s. Do I have to enable maybe something in the ./configure ?

    My target is to get a stream at : http://localhost:8090/test1.mjpg

    Can anyone help me please ?

  • generating silence audio using ffmpeg with specific bitrate and duration time less than one second cannot get the audio with the desired bitrate

    28 août 2018, par bambooom

    I’d like to generate a silence audio file using ffmpeg with specific bitrate and the duration is less than one second. I found that the generated audio file does not have the desired bitrate. But if I expand the duration to 2 seconds, the bitrate seems to be correct.

    For example :

    ffmpeg -f lavfi -i anullsrc=r=22050:cl=mono -t 0.3 -acodec mp3 -ab 48k -y silence.mp3

    The generated silence.mp3’s bitrate seems not 48kb/s :

    $ ffprobe silence.mp3

    Is there any way to keep the bitrate as desired ?

  • Impossible to convert between the formats supported by the filter '...' - Error reinitializing filters

    14 novembre 2023, par Fabien Biller

    I am using this ffmpeg command(values removed for simplicity)

    &#xA;

    ffmpeg -hwaccel cuvid -c:v h264_cuvid -y -ss 1 -i "FILE0001.MOV" -ss 0 -i "GOPR0621.MP4" -filter_complex &#xA;[0:v][1:v]&#xA;  midequalizer&#xA;[al];&#xA;[al]&#xA;  yadif&#xA;  lenscorrection&#xA;  scale&#xA;[vl];&#xA;[1:v]&#xA;  lenscorrection&#xA;  scale&#xA;[vr];&#xA;[vl][vr]&#xA;  hstack=shortest=1 &#xA;-an -c:v h264_nvenc -preset slow "output.mp4"&#xA;

    &#xA;

    on a machine with a cuda graphics card.

    &#xA;

    I get

    &#xA;

    &#xA;

    The same command without CUDA works, ie

    &#xA;

    ffmpeg -y -ss 1 -i "FILE0001.MOV" -ss 0 -i "GOPR0621.MP4" -filter_complex &#xA;[0:v][1:v]&#xA;  midequalizer&#xA;[al];&#xA;[al]&#xA;  yadif&#xA;  lenscorrection&#xA;  scale&#xA;[vl];&#xA;[1:v]&#xA;  lenscorrection&#xA;  scale&#xA;[vr];&#xA;[vl][vr]&#xA;  hstack=shortest=1 &#xA;-an "output.mp4"&#xA;

    &#xA;

    How do I make it work on a Windows 10 machine with cuda ?

    &#xA;
