Other interesting software
13 avril 2011, parWe 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.

How to increase compression speed for FFmpeg ?
26 mars 2015, par ShaileshI have used following command for compress video in android.
ffmpeg -y -i /sdcard/DCIM/Camera/VID_20150326_125017.mp4 -strict experimental -s 640x360 -r 25 -vcodec mpeg4 -b 1000k -ab 48000 -ac 2 -ar 22050 /sdcard/videokit/out.mp4
Above command is a work properly, but it’s taking too much time for compression.
An 80MB video file takes around 3 minutes to compress to an 8MB file. Is there any way I can reduce this time. -
Revision 83cbe22623 : Speed up non-rd mode decision search This commit makes the encoder to explicitl
18 mars 2015, par Jingning HanChanged Paths :
Modify /vp9/encoder/vp9_pickmode.c
Speed up non-rd mode decision searchThis commit makes the encoder to explicitly calculate the SAD
associated with the LAST_FRAME motion vector and compare it to
that of the GOLDEN_FRAME given by integral projection motion
estimation. It skips the expensive sub-pixel motion search over
GOLDEN_FRAME when the LAST_FRAME can provide fairly good motion
compensated prediction quality.For dark720p speed -6 single thread goes from
