    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) (...)

  • Merge multiple videos without using command line-FFMPEG [on hold]

    19 avril 2018, par Valgrind1691

    I am developing an android application which has video processing features involved.
    For video processing I have been working with FFMPEG library. As for now ffmpeg is directly being consumed by android and the processing is being done by
    framing commands and executing it using ffmpeg executable running in the background.
    This approach has two drawbacks :

    1) Video Processing time is huge even after trying ultrafast and other options to reduce processing

    2) APK size is large

    For solving two major problems we seek c/c++ native implementation for video processing by using the ffmpeg code.
    The C/C++ code will be cross compiled for android and iOS platforms and provided to mobile platform as a library (.so file in case of Android)
    The .so file will have

    1. jni for communication between Android(java) and c/c+

    2. c++ code for functionality implementation of video processing. All
      the video processing i.e scaling, transcoding, merging,
      cropping etc will be done by C/C++ code.

    I have a query around the C/C++ side , how can we use ffmpeg not to process using command line rather we can define algorithms for the process. Transcoding, muxing etc I have achieved looking into the examples of ffmpeg but I am still unable to figure out algorithm for merging of multiple(upto 6) videos in a single video file.
    I have looked into every question posted in this context and none helped.
    Can someone help me merge videos using source code of ffmpeg without using command line ? Any help is appreciated.

  • rtp streaming using av_interleaved_write_frame or av_write_frame

    4 avril 2013, par sinan
     I am using ffmpeg windows libraries to rtsp/rtp demux and muxing. But I have problem about processing time of av_interleaved_write_frame or av_write_frame, for example for h264 encoded 1920x1080 pictures it takes 10-20 ms for p frames and 70-100 ms for I frame. I am using VLC for receiver and network bandwith is 100Mb, operating system is 32 bit windows7. If I choose smaller size picture processing time is decreases but it still over for my expectation.

    Is it normal these processing times.

    thanks,
