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. -

Trim and loop audio to the length of video
20 mai 2020, par Nguyễn TrọngI have a 30 second video and a 120 second audio.
I ran the following command to loop audio into the video but it only stopped when the audio length was reached even though I added "-shortest".
Help me. (sorry for my bad english)



String[] cmd = {"-y", "-i", video.mp4, "-i", audio.mp3,
 "-filter_complex",
 "[1:a]atrim=0:100,asetpts=PTS-STARTPTS," +
 "asetrate=44100,aloop=1:size=1*44100," +
 "aformat=sample_fmts=fltp:sample_rates=44100:channel_layouts=stereo,volume=1.0[bg];" +
 "[0:v][bg]concat=n=1:v=1:a=1[video]", "-shortest",
 "-map", "[video]", "-c:v", "libx264", "-c:a", "aac",
 "-preset", "veryfast", output, "-hide_banner"};

Extended quantizer range for high bitdepthThese changes allow 10 and 12 bit depth streams
to encode at higher quality by using a finer
quantizer. Category 6 tokens now transmit 18
extra bits instead of 14 in order to be able to
encode the greater range of output coefficients.The extended quantizer range is only used when
configured with the following options :
— enable-vp9-high
— enable-high-transforms
— enable-high-quantChange-Id : I58d2981676d67b65cc022e98cf443603d38ba6ff
