    30 janvier 2013, par Ronald S. Bultje

This commit doesn't actually change anything, but makes the mbmi state more consistent between the RD loop and the final (...)

  • Anomalie #3828 : Problème avec reverse-proxy

    16 septembre 2016, par FAb M

    EDIT : 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.

  • How to re-encode to rgb pixel_format properly in ffmpeg

    1er février 2020, par captain_majid

    I’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

[3:v] hue=s=-5, scale=240x160 [webcam];
    
[desktop][webcam] overlay=x=W-w-285:y=H-h-7:format=rgb [deskCam];
    
[4:v] format=rgba,colorchannelmixer=aa=0.5, scale=240x160 [vid];
    
[deskCam][vid] overlay=x=W-w-5:y=H-h-245:format=rgb [deskCamVid];
    
[deskCamVid][5:v] overlay=x=W-w-280:y=H-h-0:format=rgb [deskCamVidBlue];
    
[deskCamVidBlue][6:v] overlay=x=W-w-0:y=H-h-238:format=rgb [deskCamVidBlueRed];
    
[7:v] chromakey=0x00FF00:similarity=.200, scale=420x140 [kb];

-map "[final]" -map "[aud1]" -map "[aud2]" -metadata:s:a:0 title="No Music" -metadata:s:a:1 title="All sounds" out.mkv

    The 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.
