Multilang : améliorer l’interface pour les blocs multilingues
18 février 2011, parMultilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela. -

Revert "avformat/format : temporarily use old next api"
1er avril 2018, par Josh de KockRevert "avformat/format : temporarily use old next api"
This reverts commit 909e00ae816df9b6a05b1c4d0cafb794d4d0ca28.
There is no need to use the old API anymore as the new API now
behaves in the same way (treating devices as formats when loaded).Signed-off-by : Josh de Kock <josh@itanimul.li>

ffmpeg causing wrong duration on a converted .m2v video ?
10 octobre 2022, par VILEWORXI've been using ffmpeg to convert .mp4 videos to an extremely specific .m2v format for a modding project using the following command :


ffmpeg -i input.mp4 -profile:v high -codec:v mpeg2video -b:v 4000k -vf scale=512:480,colorspace=smpte170m,fps=60 -map 0 -map -0:a -maxrate 4000000 -bufsize 655360 output.m2v


However, the start and end points of the output are not the same as my input file (29 seconds). ffprobe shows "Duration : N/A, bitrate : N/A".


Strangely, the video duration is correct when loaded in Adobe After Effects, is slightly shorter in QuickTime Player, and is only 8 seconds according to Windows File Explorer (on my friend's computer). I suspect the lack of duration and bitrate displayed by ffprobe may have something to do with it, and this doesn't happen with any other format I've tried converting to.


Does anyone know how to fix this ?

aacdec : move from scalefactor ranged arrays to flat arrays
14 mai 2024, par Lynneaacdec : move from scalefactor ranged arrays to flat arrays
AAC uses an unconventional system to send scalefactors
(the volume+quantization value for each band).
Each window is split into either 1 or 8 blocks (long vs short),
and transformed separately from one another, with the coefficients
for each being also completely independent. The scalefactors
slightly increase from 64 (long) to 128 (short) to accomodate
better per-block-per-band volume for each window.To reduce overhead, the codec signals scalefactor sizes in an obtuse way,
where each group's scalefactor types are sent via a variable length decoding,
with a range.
But our decoder was written in a way where those ranges were carried through
the entire decoder, and to actually read them you had to use the range.Instead of having a dedicated array with a range for each scalefactor,
just let the decoder directly index each scalefactor.This also switches the form of quantized scalefactors to the format
the spec uses, where for intensity stereo and regular, scalefactors
are stored in a scalefactor - 100 form, rather than as-is.USAC gets rid of the complex scalefactor handling. This commit permits
for code sharing between both.
