  • Les vidéos

    21 avril 2011, par

    Comme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
    Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.
    Son avantage principal quant à lui est de bénéficier de la prise en charge native de vidéos dans les navigateur et donc de se passer de l’utilisation de Flash et (...)

  • FFMPEG - Correct command line parameters to create a H.264 Streaming MP4 from a set of images

    5 janvier 2012, par Adam

    I have no problems viewing a video created by my current parameters in a HTML5 browser, Flash player, Windows Phone 7, Android Phone, etc. However, they won't display on iPhone or iPad. If I modify the video using Super and select "Enable Streaming" checkbox they work on iPhone and iPad suddenly. We are suspecting that my command line parameters are incorrect for enabling h.264 streaming and are instead generating a "progressive download" video.

    I'm pretty new to FFMPEG and don't understand a lot of the parameters. Can anyone help correct my existing parameters, or maybe provide the missing parameters, etc ?

    Thanks in advance.

    My current FFMPEG command line paramters are :

    ffmpeg.exe 
 -r 30 
 -threads 4 
 -f image2 
 -i .\frame%05d.jpg 
 -i audioFile  
 -acodec aac 
 -ab 128k 
 -ar 44100
 -vcodec h264 
 -crf 27 
 -coder 1 
 -flags +loop 
 -cmp +chroma 
 -partitions +parti4x4+partp8x8+partb8x8 
 -me hex 
 -subq 5 
 -me_range 16 
 -g 60 
 -keyint_min 25 
 -sc_threshold 40

  • FFmpeg make mpeg2 ts without discontinuity

    31 mai 2012, par user1427162

    I have many MOV files recorded with iPhone and I want to convert them to mpeg2 TS. I want to use them for live video streaming with HTTP Live Streaming protocol.

    I set my iPhone to continiously send MOV files to server. Every video clip is 5 seconds long. I want to make mpeg2 TS out of them and add their urls to m3u8 playlist.
    I managed to do all of that, but when I try to play the stream VLC player plays only first two files in playlist, and last file in playlist at that moment.
    I searched the internet and I think this has something to do with discontinuity.

    Is there any way to convert multiple MOV files into multiple mpeg2 TS segments without discontinuity ?

    Or maybe I'm doing something else wrong ?
    Here is my ffmpeg command :

    ffmpeg.exe -i input,MOV -f mpegts output.ts

    and here is my m3u8 list :

    #EXTM3U
    
#EXT-X-PLAYLIST-TYPE:EVENT
    
#EXT-X-TARGETDURATION:10
    
#EXT-X-MEDIA-SEQUENCE:0
    
#EXT-X-MEDIA-SEQUENCE:0
    
#EXTINF:10,
    
fileSequence0.ts
    
#EXTINF:10,
    
fileSequence1.ts
    
#EXTINF:10,
    
fileSequence2.ts

    Thanks in advance
