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" (...) -

checkasm : af_afir : Use a dynamic tolerance depending on values
11 décembre 2019, par Martin Storsjöcheckasm : af_afir : Use a dynamic tolerance depending on values
As the values generated by av_bmg_get can be arbitrarily large
(only the stddev is specified), we can't use a fixed tolerance.
Calculate a dynamic tolerance (like in float_dsp from 38f966b2222db),
based on the individual steps of the calculation.This fixes running this test with certain seeds, when built with
clang for mingw/x86_32.Signed-off-by : Martin Storsjö <martin@martin.st>

25 septembre 2016, par Michael Niedermayeravformat/utils : Discard huge timestamps which would cause overflows if used in basic computations
Allowing larger timestamps makes it impossible to calculate basic things like the
difference of 2 timestamps or their sum without checking each individual computation for
overflow.
This should avoid a significant number of overflow checksFixes Ticket5136

Short HLS MPEG2 Video Segments Do Not Play
24 août 2019, par Jon HI’ve been attempting to cut a video into small segments (words), to be rearranged. While I’ve been able to do it with FFMPEG, cutting into segments and using the fast concat demuxer to reassemble the segments, I am trying to speed it up.
I have been doing this by splitting the original video into short MPEG2 .ts segments for each word :
ffmpeg -ss 1 -to 1.5 -i "source.mp4" -c:v libx264 -b:v 1200k -c:a aac -b:a 192k -hls_flags single_file "word.ts"
I have then tried making a m3u8 playlist of these short video segments, but I found that only segments around 2 seconds or more, play at all.
I then tried using the ’cat’ command to join these segments into a single file, which I understand should be possible with MPEG2 streams. However, this did not play all the segments either.
To test if all the segments were present in this concatenated file, I used FFMPEG to convert it back into an MP4 file, and all the segments were present.
I would appreciate any suggestions on producing the segments, and concatenating individual segments simply without FFMEPG. My project isn’t viable if having to call FFMPEG each time, but would work great if I can simply concatenate words together.
