  • Creating farms of unique websites

    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" (...)

    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.

  • Encoding and segmenting HD video for DASH [closed]

    13 mars 2013, par user2163937

    I am trying to encode video for implementing DASH, for encoding I am using this command line...

    ffmpeg -i sample.ts -f mpegts -acodec libfaac -ar 44100 -ab 64k -s 480x270
    
-vcodec libx264 -b 500k -r 25 -flags +loop -partitions
    
+parti4x4+partp8x8+partb8x8 -subq 5 -refs 6  -keyint_min 10 -i_qfactor 0.71 
    
-maxrateD 500k -bufsize 500k -rc_eq 'blurCplx^(1-qComp)' -qmin 10 -qmax 51
    
-qdiff 4 -level 30 -aspect 16:9 -g 30 -async 2 out.ts

    For segmentation I use this command line

    ffmpeg -i out.ts -c copy -map 0 -f ssegment -segment_time 4 -segment_list
    
out.list seg%d.ts  

    And I use the various resolutions and parameters according to the table given in this link.

    Given resolutions and parameters are working fine for me, I can able to get smooth transition among various resolutions. But problem arises when I try to use HD resolution i.e 1280x720, there is a visible flicker when video switches from HD to other resolution or vice-versa. I cannot figure out the problem.

  • Concatenate DASH audio and video to single file

    13 mars 2017, par Andreas

    First of all, I have a folder with about 200 video and audio segments (m4v and m4a) of a video that was live streamed as DASH video. Now - without having the original file - I want to concatenate those parts to a single, playable video file.

    To mention what I already tested :

    • concatenate via the Unix terminal command cat ; unfortunately this won’t help to make the video playable in any media player again
    • using ffmpeg’s merge abilities via files.txt ; with the same unsuccessful result

    I’m definitely not an expert (otherwise I probably wouldn’t ask) but the problem may be also the missing mpd and/or init file (as far as I could skim in the standard).

    Don’t get me wrong : I don’t want to get a bit to bit identical result of the original file. All I want to achieve is a single playable mp4 file of aforesaid video.

    I also tried to make a own mpd file, but the "stream" won’t play. FYI, I tried playing it in the current VLC 3.0.0 git, since the current stable versions seems not to support DASH.
    If it helps, here the video codec :

    id="live-hd_H264"
    
mimeType="video/mp4"
    
codecs="avc1.4d401f"
    
width="396"
    
height="704"

    So, can anybody help me ?

    Kind regards !
