  • Automated installation script of MediaSPIP

    25 avril 2011, par

    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
    The documentation of the use of this installation script is available here.

  • Video encoding from a file which is being creating from another recorder program

    3 décembre 2011, par John Smith

    well, this is an extreme question. There's a screen capturer program which records video to a file (only this program can record from the target application !) and I would like to stream it with FFmpeg by UPD/TCP.
    The question is how to encode a file what is being writing. Sadly that program creates big file and not seems to be accept any way to change encodings.

  • FFMPEG - 60 seconds from any part of video

    3 octobre 2014, par RussellHarrower

    What I want to do is create a 60 second FLV from a video that is uploaded.
    But I dont want to always get the first 60 seconds, if possible I would like to get the middle part of the video. but if not I want to get a random 60 second part of a video file and create the flv.

    I am using the following script to make the FLV file

    $call="/usr/bin/ffmpeg -i ".$_SESSION['video_to_convert']." -vcodec flv -f flv -r 20 -b ".$quality." -ab 128000 -ar ".$audio."  ".$converted_vids.$name.".flv -y 2> log/".$name.".txt";
    

    
$convert = (popen($call." >/dev/null &", "r"));
    
pclose($convert);

    So my question is, how do i get 60 seconds from a video randomly and convert it ?

  • DirectShow RTSP SourceFilter with MPEG-4 Video Stream

    5 octobre 2011, par 6.45.Vapuru

    I create a simple direct show source filter using FFmpeg.I read rtp packets from RTSP source and give them to decoder. It works for h264 stream.

    MyRtspSourceFilter[H264 Stream] ---> h264 Decoder --> Video Renderer

    The bad news is that it does not work for MPEG-4. I can able to connect my rtsp source filter with MPEG-Decoder. I got no exception but video renderer does not show anything. Actually just show one frame then nothing [just stop]... Decoders and Renderers are 3rd party so i can not debug them.

    MyRtspSourceFilter[MP4 Stream] ---> MPEG-4 Decoder --> Video Renderer

    I can able to get rtp packets from MPEG-4 RTSP Source using FFmpeg sucessfully.There is no problem with it.

    It seems that i have not set something(?) in my Rtsps Source
    Filter which is not necessary for H264 stream but may be important for
    MPEG-4 stream

    What may cause this h264 stream and MPEG-4 stream difference in a direct show rtsp source filter ? Any ideas.

    More Info :

    — First i try some other rtsp source filters for MPEG-4 Stream...Although my rtsp source is same i see different subtypes in their pin connections.

    — Secondly i realy get suspicious if the source is really MPEG-4 SO i check with FFmpeg...FFmpeg gives the source codec id as "CODEC_ID_MPEG4".

    Update :
    [ Hack ]

    I just set m_bmpInfo.biCompression = DWORD('xvid') it just worked fine...But it is static. How to dynamically get/determine this value using ffmpeg or other ways...
