  • Le plugin : Podcasts.

    14 juillet 2010, par

    Le problème du podcasting est à nouveau un problème révélateur de la normalisation des transports de données sur Internet.
    Deux formats intéressants existent : Celui développé par Apple, très axé sur l’utilisation d’iTunes dont la SPEC est ici ; Le format "Media RSS Module" qui est plus "libre" notamment soutenu par Yahoo et le logiciel Miro ;
    Types de fichiers supportés dans les flux
    Le format d’Apple n’autorise que les formats suivants dans ses flux : .mp3 audio/mpeg .m4a audio/x-m4a .mp4 (...)

  • Encode RGB565 raw data using ffmpeg libx264 for android

    23 janvier 2014, par nmxprime

    i have below questions regarding android implementation

    1. How various video codecs differ especially `which are stream based and which are frame based'

    2. Over many forums and questions everyone is talking SPS,PPS,etc., so where i can find enough details about codec(Please mention something other than RFC documents !!) to understand it and use ffmpeg relevantly ?

    3. From this Is it possible to use in-built HW Decoders od android devices ? If so, How ? Do i need to use OpenMax-IL (or AL or DL , i mean which is for what ?)

    4. Does ffmpeg supports H264 encoding of RGB (or RGBA) or RGB565(or RGB555) input data through libx264 ?

    5. If my requirement is only h264 encode & decode, can i use libx264 without ffmpeg ?If so any sample/guide ?

  • ffmpeg convert images with name pattern into video [duplicate]

    27 mars 2017, par passion

    This question already has an answer here :

    I am converting png images into a video using ffmpeg.

    My png file names are like this :

    image1_xy.png
    
image2_xy.png
    
image3_xy.png
    
image4_xy.png
    
...
    
image10_xy.png
    
image11_xy.png
    
...
    
image100_xy.png
    
image101_xy.png
    
...

    my script is the following :

    ffmpeg -r 1 -f image2 -s 1920x1080 -i image%03d.png -vcodec libx264 -crf 25  -pix_fmt yuv420p test.mp4

    which is working only when the file names are like image001.png , image002.png...

    How should i modify this to take into account the file name pattern I have ?

    update

    i don’t mind if the answer suggests to use a bash script to rename files in the order they appear with the right pattern.
