29 mars 2017, par T4ng10rI’ve got bunch of movies from two different Panasonic devices. As long as I concat movies from only ONE device - final movie is smooth.
However, when I add movie clip from second device, right after final movie ends playing movies from first device it display audio and only still images from movie clip from other device.ffmpeg -f concat -i mylist.txt -c copy final_movie.MP4
Example ffprobe :
Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'S6810001.MP4':

How to re-encode to rgb pixel_format properly in ffmpeg
1er février 2020, par captain_majidI’m using this command to record from multiple inputs :
ffmpeg -y
-f dshow -rtbufsize 1024M -thread_queue_size 1024 -probesize 64M -i video="screen-capture-recorder" -framerate 30
-f dshow -rtbufsize 16M -i audio="virtual-audio-capturer"
-f dshow -rtbufsize 16M -i audio="Microphone (DroidCam Virtual Audio)"
-f dshow -rtbufsize 512M -thread_queue_size 512 -probesize 50M -i video="DroidCam Source 3"
-stream_loop -1 -i ".\media\background sounds\blue.mp4"
-i ".\media\pictures\Webcam Overlay\blue_.png"
-i ".\media\pictures\Webcam Overlay\red.png"
-f gdigrab -rtbufsize 512M -thread_queue_size 512 -probesize 64M -itsoffset 0.80 -i title="NohBoard v1.2.2" -framerate 60 -draw_mouse 0
-filter_complex "

-map "[final]" -map "[aud1]" -map "[aud2]" -metadata:s:a:0 title="No Music" -metadata:s:a:1 title="All sounds" out.mkvThe problem is the colors are not as bright as I want unless adding
:format=rgb
to all overlays like seen above, but this delays my encoding a lot, also when I press ’Q’, only a small part of the video (like 1m of 3m) is produced.Also If you see any unnecessary switches or non-optimal ones, please advise.

Anomalie #3828 : Problème avec reverse-proxy
16 septembre 2016, par FAb MEDIT : petite information complémentaire pour clarifier :
Le but est de mutualiser un reverse-proxy pour plusieurs applications déterminer par la clé CLE (ex : http://tld.fr/CLE/ ).
Mais au final si on a les moyens de créer un nom de domaine et un vhost ne servant que de reverse proxy sur la machine d’entrée, SPIP ne pose pas de problème. Mais c’est moyen.
