  • 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.

    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.

    Extending ext_tx expt to include dst variants

    Extends the ext-tx experiment to include regular and flipped
    DST variants. A total of 9 transforms are thus possible for
    each inter block with transform size <= 16x16.

    In this patch currently only the four ADST_ADST variants
    (flipped or non-flipped in both dimensions) are enabled
    for inter blocks.

    The gain with the ext-tx experiment grows to +1.12 on derflr.
    Further experiments are underway.

  • FFPMEG : stream local file to UDP address, make client aware about video length and current frame time offset (make stream seekable ?)

    10 décembre 2014, par klim

    Just started to use FFMPEG. This is a really great library which is capable of video life transcoding and streaming.

    I use following commands to transcode and stream local video file to UDP address :
    ffmpeg -y -re -i inputvideo.mpeg2 -vsync 1 -vcodec mpeg4 -b 1600k -r 15 -crf 20 -acodec aac -ar 44100 -strict -2 -f mpegts udp ://192.168.1.30:1234

    It works smooth. I can open this udp address in VLC player and play life stream.

    Does anybody know how to make client aware about video duration and current time stamp ?

    Ideally would be nice to make stream seekable, as far as I understand it is not possible, but at least I would like to tell VLC client the total duration of the video and current frame time stamp, so it could show the progress.

    Thanks.

  • ffmpeg c/c++ get frame count or timestamp and fps

    25 octobre 2020, par broschb

    I am using ffmpeg to decode a video file in C. I am struggling to get either the count of the current frame I am decoding or the timestamp of the frame. I have read numerous posts that show how to calculate an estimated frame no based on the fps and frame timestamp, however I am not able to get either of those.

    &#xA;&#xA;

    What I need : fps of video file, timestamp of current frame or frame no(not calculated)

    &#xA;&#xA;

    What I have : I am able to get the time of the video using

    &#xA;&#xA;

    pFormatCtx->duration/AV_TIME_BASE&#xA;

    &#xA;&#xA;

    I am counting the frames currently as I process them, and getting a current frame count, this is not going to work longterm though. I can get the total frame count for the file using

    &#xA;&#xA;

    pFormatCtx->streams[currentStream->videoStream]->nb_frames&#xA;

    &#xA;&#xA;

    I have read this may not work for all streams, although it has worked for every stream I have tried.

    &#xA;&#xA;

    I have tried using the time_base.num and time_base.den values and packet.pts, but I can't make any sense of the values that I am getting from those, so I may just need to understand better what those values are.

    &#xA;&#xA;

    Does anyone know of resources that show examples on how to get this values ?

    &#xA;
