Creating farms of unique websites
13 avril 2011, parMediaSPIP 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" (...) -
Mise à disposition des fichiers
14 avril 2011, parPar défaut, lors de son initialisation, MediaSPIP ne permet pas aux visiteurs de télécharger les fichiers qu’ils soient originaux ou le résultat de leur transformation ou encodage. Il permet uniquement de les visualiser.

FFMpeg slide text from right to left an leave from left to right after x seconds
13 août 2018, par Marco van 't KloosterI’m trying to slide a text inside my video from right to left and leaving the video after 13 seconds.
The text has to stay there for 13 seconds and the leave in the opposite direction the video.Right now I’m using the following command :
ffmpeg -i Pool\ scores.m4v -vf "[in]drawtext=fontfile=/usr/share/fonts/truetype/msttcorefonts/Arial.ttf:fontsize=40:fontcolor=white:x=900:y=570:text='Marco':enable='between(t,11,24)' [out]" -c:v libx264 scrolling.m4v
So the text
Marco
have to be at x=900 and y=570. Thats also the coordinate where the text have to leave from.The idea is to create a pool score board where the video is auto generated with dynamic text. In this image there is an example of what the animation have to look like. I’ve to retime it tom match the same speed.
See exampleThanks in advance !!

Use ffmpeg to add text subtitles
25 novembre 2016, par 0-alphaI am trying to add text subtitles to an .mp4 container using ffmpeg :
ffmpeg -i input.mp4 -i input.srt -map 0.0 -map 0.1 -map 1.0 output.mp4
When I am trying to run this line, it gives me an error :
Nmber of stream maps must match number of output streams.
If I try to change the mp4 to mkv (although mp4 supports text subtitles), like this :
ffmpeg -i input.mp4 -i input.srt -map 0.0 -map 0.1 -map 1.0 output.mkv
It correctly maps the streams, but gives an error :
Encoder (codec id 94210) not found for output stream #0.2
When I launch
ffmpeg -codecs
I can see that srt codec is supported as decoder and encoder, however I am not sure what is used for mp4 and mkv subs encoding, and whether I need to switch it on or compile separately.

changes intra coding to be based on txfm blockThis commit changed the encoding and decoding of intra blocks to be
based on transform block. In each prediction block, the intra coding
iterates thorough each transform block based on raster scan order.This commit also fixed a bug in D135 prediction code.
TODO next :
The RD mode/txfm_size selection should take this into account when
computing RD values.Change-Id : I6d1be2faa4c4948a52e830b6a9a84a6b2b6850f6
