Support de tous types de médias
10 avril 2011Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

Supporting all media types
13 avril 2011, parUnlike most software and media-sharing platforms, MediaSPIP aims to manage as many different media types as possible. The following are just a few examples from an ever-expanding list of supported formats : images : png, gif, jpg, bmp and more audio : MP3, Ogg, Wav and more video : AVI, MP4, OGV, mpg, mov, wmv and more text, code and other data : OpenOffice, Microsoft Office (Word, PowerPoint, Excel), web (html, CSS), LaTeX, Google Earth and (...)

Can this be a TC burn-in ; 993[1001(1001)1100]1108 - start frame 1001 end 1100 ; (1001) is current frame ;993 &1108 are head and tail 8 frame handles
21 novembre 2022, par Abraham ThomasNeed to create a Timecode overlay on videos in frames as "993[1001(1001)1100]1108"
Here -start frame is 1001 and last frame is 1100 ;
the (1001) is the current frame counter
and 993 and 1108 are head and tail handles (1001-8 and 1100+8)


This is currently done in Davinci Resolve by using below text script (was helped in another forum) :
comp.RenderStart+1001-8 .. " [".. comp.RenderStart+1001 .. " (" .. time+1001 ..") " .. comp.RenderEnd +1001 .. "] " ..comp.RenderEnd +1001+8


At times there are 200 + video clips requiring this ; if same can be achieved in ffmpeg this will speed up our workflow. Is this possible using a single ffmpeg command ; please help


In this forum someone had posted a Timecode overlay command, which gives the current frame number ;
I've used this and this below single command works for me :


ffmpeg -i inputvid.mp4 -vf "drawtext=fontfile=Arial.ttf : text='%frame_num' : start_number=1001 : x=(w-tw)/2 : y=h-(2*lh) : fontcolor=white : fontsize=55 : box=1 : boxcolor=black : boxborderw=5" -c:a copy D :\Test\outputvid.mp4


Is there a way to add to this command ; the first frame and last frame of the video automatically detected by ffmpeg (I'm on windows) ;

ffmpeg record pulseaudio has some crackles
8 janvier 2021, par boygiandiI'm trying to record audio from pulseaudio (on Centos 7), using ffmpeg. But the audio is not smooth, it has some crackles, noise after few seconds
Please check this video link : https://www.facebook.com/watch/live/?v=692754594726722&ref=watch_permalink


The ffmpeg command looks like this


ffmpeg -fflags +igndts -framerate 30 -s 1920x1130 -draw_mouse 0 -f x11grab -i :1085.0+nomouse -f pulse -i sinkgstvDViJbLFIaUBLdTxTeLtr.monitor -c:v libx264 -filter:v crop=1920:1080:0:50 -g 60 -r 30 -bufsize 2M -b:v 7M -vbsf h264_mp4toannexb -pix_fmt yuv420p -strict experimental -preset ultrafast -c:a aac -async 1 -vsync 1 -b:a 128k -bsf:a aac_adtstoasc -metadata comment=gstvDViJbLFIaUBLdTxTeLtr -f flv "rtmps://live-api-s.facebook.com:443/rtmp/4248189238527878?s_bl=1&s_psm=1&s_sc=4248189291861206&s_sw=0&s_vt=api-s&a=Abx_pMiM4_ccqBcS"
