  • 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.

  • ffmpeg 1080p50 50fps unsupported on some samsung models, resulting in Error

    15 octobre 2019, par Sambir

    So I use FFMPEG for live transcoding using nvenc gpu acceleration. I recently did some minor improvements by upping the framerate to 1080p50 instead of 1080p25.

    I noticed that this caused "error" messages on some samsung models. I was wondering if it is due to my code, can we up the compatibility or are the tv’s just unable to playback 1080p50 which I think is really strange.

    This is the command I use :

    ffmpeg -hwaccel cuvid -vcodec h264_cuvid -vcodec h264_cuvid -i 'rtmp://127.0.0.1:8001/input/bla' -max_muxing_queue_size 1024 -map 0:v -map 0:a -vf yadif_cuda=1 -acodec libfdk_aac -b:a 128k -c:v h264_nvenc -preset llhq -vprofile high -level 4.2 -rc:v vbr -qmin:v 18 -qmax:v 42 -b:v 6M -maxrate 6M -bufsize 12M -threads 0 -r 50 -g 200 -f flv 'rtmp://127.0.0.1:8001/input/test'

    Like 80% of the models, samsung/lg/sony are able to play it but some small amount of samsung tv’s give stream error. I have a feeling it is just the high framerate where the tv/app is unable to play it back resulting in "streaming error". Because on even older lg models the stream plays back just perfectly. It does not seem to be a format or something...

  • avformat/flvenc : Avoid unnecessary seek

    avformat/flvenc : Avoid unnecessary seek

    When shifting the already written data in order to write the keyframe
    
index, the flv muxer would first store the pre-shift size, then
    
calculate how big the index will be eventually, then perform some seeks
    
to update some size fields, then seek back to the end of the file to get
    
the new position, followed by a seek to the position where writing will
    
really start. Seeking back to the (already known) end position (that is
    
actually used to perform this seek) to get the end position is of course
    
unnecessary. It has been removed.

  • Store a videostream from webcam but as 1s long files that can later be merged together [duplicate]

    17 février 2018, par Jennifer R

    This question is an exact duplicate of :

    I’m trying to store a videostream from a webcam but need it to be 1s long files. I have never worked with storing videofiles so i’m not sure if and how i should use opencv and how those videofiles need to be contained that i can merge them together. I tried the old windows cmd code

    copy /b *.avi combined.avi

    but since avi is sort of a container type i only got as far as the first file. I’m guessing since there’s some container data limiting the first file and i can’t watch it.

    I need help in both questions. How can i store a video stream and how do i merge those videos ? Do i use ffmpeg for the latter and is it possible to edit the container data to the correct length ?
