  • Support de tous types de médias

    10 avril 2011

    Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

    We don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
    The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
    We don’t know them, we didn’t try them, but you can take a peek.

  • RN CameraRoll gives uri as ph : //

    30 septembre 2020, par Roman Adigezalov

    Faced such a problem, I get a video using CameraRoll in order to later transfer this file to FFMpeg, but the problem arises in the fact that the path to the file is on ios using the ph protocol. How to be in this situation ? How do I get real access to the file ?

    


  • FFmpeg video filters corrupt mp4 file

    12 septembre 2018, par kataroty

    I am trying to add visual filters to mp4 files using FFmpeg.

    I have tried many filters, but 4 of them worked out of which only 1 worked worked perfectly. I am using them in an Android application, but I tried the same command lines on windows cmd using FFmpeg and the result is same. With 3 filters the .mp4 is unplayable by many players and also Androids mediaplayer. I can still play the "corrupt" files on VLC and players that have many codex`s, but I need them to work perfectly.

    The only filter working as intended is Black and White and the command is (have tried both -vf and -filter_complex) :

    -i origin.mp4 -filter_complex hue=s=0 blackWhite.mp4

    The other 3 are Sepia, Vintage and Negative

    "colorchannelmixer=.393:.769:.189:0:.349:.686:.168:0:.272:.534:.131",  "curves=vintage", "curves=negative"

    Since I cannot upload video files here, I have added a link of 3 files, the original video file, black/white filtered file (that works), vintage file (that does not work).

  • avcodec/v4l2_m2m_dec : remove redundant packet and fix double free

    avcodec/v4l2_m2m_dec : remove redundant packet and fix double free

    v4l2_receive_frame() uses two packets s->buf_pkt and avpkt. If avpkt
    
cannot be enqueued, the packet is buffered in s->buf_pkt and enqueued in
    
the next call. Currently the ownership transfer between the two packets
    
is not properly handled. A double free occurs if
    
ff_v4l2_context_enqueue_packet() returns EAGAIN and v4l2_try_start
    
returns EINVAL.
    

    In fact, having two AVPackets is not needed and everything can be
    
handled by s->buf_pkt.
    

    This commit removes the local avpkt from v4l2_receive_frame(), meaning
    
that the ownership transfer doesn't need to be handled and the double
    
free is fixed.
