Initialisation de MediaSPIP (préconfiguration)
20 février 2010, parLors de l’installation de MediaSPIP, celui-ci est préconfiguré pour les usages les plus fréquents.
Cette préconfiguration est réalisée par un plugin activé par défaut et non désactivable appelé MediaSPIP Init.
Ce plugin sert à préconfigurer de manière correcte chaque instance de MediaSPIP. Il doit donc être placé dans le dossier plugins-dist/ du site ou de la ferme pour être installé par défaut avant de pouvoir utiliser le site.
Dans un premier temps il active ou désactive des options de SPIP qui ne le (...) -

What is the difference between

6 octobre 2023, par SamTechI wrote a
bashscript that is generating command to encode video and create HLS playlist.

Here is the script. To make it short and clear, i fill variables with hard-coded values.


#!/bin/bash

# below variables are generated from some other script

basic="-hide_banner -y -i Sample.mp4 -profile:v main -crf 20 -sc_threshold 0 -g 50 -keyint_min 50 -hls_time 6"

renditions="-c:v:0 h264 -filter:v:0 scale=w=426:h=240:force_original_aspect_ratio=decrease -b:v:0 128k -maxrate:v:0 136k -bufsize:v:0 192k -c:v:1 h264 -filter:v:1 scale=w=640:h=360:force_original_aspect_ratio=decrease -b:v:1 256k -maxrate:v:1 273k -bufsize:v:1 384k -b:a 128k -c:a aac -ar 48000 -ac 2"

mapping="-map 0:v -map 0:v -map 0:a"
stream_map="-var_stream_map \"v:0,agroup:audio v:1,agroup:audio a:0,agroup:audio\""

hls="-hls_list_size 0 -f hls -hls_playlist_type vod -hls_segment_type mpegts -master_pl_name master.m3u8 -y %v_seg.m3u8"

# show final command
echo "Command:"
echo "ffmpeg ${basic} ${renditions} ${mapping} ${stream_map} ${hls}"

# execute command
ffmpeg ${basic} ${renditions} ${mapping} ${stream_map} ${hls}


Here is complete output from the script, along with the error it is giving.

Converting mp4 file downloaded via youtube-dl from periscope by using ffmpeg gives error
20 mars 2018, par MonsterMMORPGThis is command i have used to download from periscope by using latest youtube-dl
youtube-dl -v periscopeurlThen i am running this command to convert it to a proper MP4
ffmpeg -i gg.mp4 -c:v libx264 -preset veryslow -crf 18 -c:a aac -b:a 192k -pix_fmt yuv420p gg2.mp4I am using latest youtube-dl and ffmpeg
The error i am getting is shown below
So how can i fix this error ? The file can not be played properly on k lite mega codec player but it can be played on vlc player however can not go to any specific time etc. so it really needs to be properly re-encoded
