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.

Prérequis à l’installation
31 janvier 2010, parPréambule
Cet article n’a pas pour but de détailler les installations de ces logiciels mais plutôt de donner des informations sur leur configuration spécifique.
Avant toute chose SPIPMotion tout comme MediaSPIP est fait pour tourner sur des distributions Linux de type Debian ou dérivées (Ubuntu...).

how to embed subtitle to a video file without burn (html5)
26 juin 2015, par haybeyei’ve a cdn hosting and there are some video files on it. and i’ve subtitles for videos. as you know, osx or ios doesn’t allow subtitles on fullscreen mode. i’ve found a solution with ffmpeg (burning) but it burns video with hardcode :
https://trac.ffmpeg.org/wiki/HowToBurnSubtitlesIntoVideo
is there any other way to do it without hardcode (maybe a media server) ? because i’ve 5 different subtitles for each video file. and can’t do it with hardcode.
any helps would be great..
best regards.

What's the difference with crf and qp in ffmpeg ?
12 novembre 2024, par NovaI read https://trac.ffmpeg.org/wiki/Encode/H.264 about h264 encoding and discovered
qp
.

Q1 : What are the differences with crf and qp ?

Q2 : Is it better to use qp over crf overall, or is it only if for using qp 0 for best lossless ?

Q3 : Does qp have a known sensible setting if it's preferred ? So far, I know crf has the default value of 23 while 18 is a sensible preferred increase in quality, although I don't understand why 18 wouldn't be default if better sensible lossless.

Q4 : Would changing either of them cause incompatibility with non-ffmpeg players or just qp ?

I'm converting from webm to mp4.


I was going to test crf 23 and 18 and pick which is best but I can't seem to find any concrete information on this comparison or about
qp
.
