    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

    ffplay : toggle full screen when double-clicking the video window with the left mouse button

    Now that the seek only happens with the right mouse button, it makes
    
sense to toggle full screen when double-clicking with the left mouse
    
button, like other video players do.

  • Convert TIFF images sequence to lossless movie FFMPEG

    9 janvier 2016, par Rarez

    I would like use a h265 codec(FPS must be equal to 25) to save loseless wideo from sequence of TIFF images. I have a problem with save it. I supose that it is little mistake. I tried many combinactions of commands here is last one :

    ffmpeg -f image2 -r $FRAMERATE -i IMG_%03d.tif -vcodec libx265 -x265-params lossless movie.mp4

    And output :

    [libx265 @ 0x2bcaf40] 4:2:2 and 4:4:4 support is not fully defined for HEVC yet. Set -strict experimental to encode anyway.
    
Output #0, mp4, to 'movie.mp4':
    
    Stream #0:0: Video: hevc, none, q=2-31, 128 kb/s, SAR 1:1 DAR 0:0, 25 fps
    
    Metadata:
    
      encoder         : Lavc57.20.100 libx265
    
Stream mapping:
    
  Stream #0:0 -> #0:0 (tiff (native) -> hevc (libx265))
    
Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height

    I will be very glad for any help. Thanks

  • FFMPEG convert .avi into playable iOS movie mp4

    8 janvier 2016, par Julien Klindt

    I’m trying to convert an avi file which is h264 encoded baseline4.0 to a new h264 mpeg file that is encoded with baseline3.

    The file original file is not playable on any iOS device, due to baseline4.0 (I think ?)

    I’m using this wrapper class here https://github.com/OpenWatch/FFmpegWrapper

    but actually I have no clue how to set baseline. I can convert to mpeg4, but it seems that defaults everytime to baseline4.0.

    I tried to set it on the AVCodecContext

    AVCodecContext *outputCodecContext = outputStream->codec;
    
outputCodecContext->level = 31;
    
outputCodecContext->profile = FF_PROFILE_H264_BASELINE;

    but this has no effect.

    Perhaps anybody has a clue, or has a better FFMPEGWrapper.
