  • 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 (...)

  • ffmpeg encoding plays very fast. Audio.mp4 and Video.mp4 work, but both together don't

    25 février 2013, par Peter.O

    In both steps 3 and 4 below, the .mp4 plays normally. However, although I've used what seems to be the same settings in the last step (audio + video), that step does not work. The video plays more than 10 times too fast... also the audio does not play.

    The ffmpeg messages for step 5 show that it has included audio.

    Output #0, mp3, to '/tmp/test.mp4':
    
    Stream #0.0: Video: libx264, yuv420p, 720x480, q=2-31, 90k tbn, 23.98 tbc
    
    Stream #0.1: Audio: libmp3lame, 48000 Hz, stereo, s16, 128 kb/s

    Subsequently running ffmpeg -i shows no trace of the audio, but it does report on the video... What have I missed, to get it muxed properly ?...

    #!/bin/bash
    

    
# 1. create Audio 
    
wine avs2pipe.exe audio "$src_avs" >"$temp_pcm"
    

    
# 2. create Video 
    
wine avs2yuv.exe "$src_avs" - |
    
  x264 --stdin y4m --output "$temp_h264" - 2>/dev/null
    

    
# 3. This works.  (audio only)
    
# encode `audio.mp4 
    
ffmpeg -acodec pcm_s16le -f u16le -ac 2 -ar 48000 -i "$temp_pcm" \
    
       -acodec libmp3lame -f mp3 -ar 48000 -ab 128k  -y "$audio_mp4"
    

    
# 4. This works.  (video only)
    
# encode `video.mp4 
    
ffmpeg -i "$temp_h264" \
    
       -vcodec copy -y "$video_mp4"
    

    
# 5. This DOES NOT work!  It plays very fast.
    
# encode `final.mp4' 
    
ffmpeg -acodec pcm_s16le  -f u16le  -ac 2 -ar 48000  -i "$temp_pcm" \
    
       -i "$temp_h264" \
    
       -acodec libmp3lame -f mp3 -ar 48000 -ab 128k \
    
       -vcodec copy \

  • Add 2 pictures to video with durations ? [duplicate]

    24 juin 2013, par jesper

    This question already has an answer here :

    I am trying to add 2 different images into a video with ffmpeg.

    image1.jpg should show the first 10 seconds of the movie and youtubeLOL.png should show the next 6 minutes of the video.

    So the command should tell us also to repeat the pictures to get a length for 6 minutes and 10 seconds. How can i do this ? I have tried this :

    (It's not even working)

     passthru("ffmpeg -f image2 -loop 1 -vframes 100 -i /home/psafari/public_html/youtube_images/movie_" . $id . ".jpg -vcodec mpeg4 /home/psafari/public_html/youtube_videos/movie_" . time().".avi");

    Here is output :

  • Processing video using ffmpeg and saving the output to MongoDB

    10 juillet 2013, par kheya

    I have user uploaded video saved in a folder (can be in any of 5/6 formats)
    I have 2 needs.

    • Extract 3 frame images (that I will show to user for possible thumbnail
    • Convert the video to one or more other formats (flv + WebM)

    I am planning to use FFMPEG command line tool.

    How do I write the output from FFMPEG to MongoDB gridFS ?

    Is it even possible or I have to write the files to folder first & then save to gridFS ?

    Thanks
