Creating farms of unique websites
13 avril 2011, parMediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

ffmpeg amix filter on mp3 with image
20 novembre 2018, par cutoffurmindI use ffmpeg to concatenate 2 mp3 files with amix filter (see full log).
It works fine for mp3 files without any meta but it fails with mp3 files with cover image in meta, result file length is less then 1 second.
How could I fix it in same command ?
Here is full log :
localhost:Music user$ ffmpeg -i input.mp3 -i /opt/docker/tag_long.mp3 -filter_complex amix=inputs=2:duration=shortest,volume=2 -codec:a libmp3lame -q:a 5 out.mp3 -report

How do i get ffprobe to parse 'TAG : timecode' into ffmpeg 'drawtext' command ? (Bash Terminal)
4 juin 2019, par MylesI have a .mov file that contains original source timecode metadata but i can’t figure out a way to get ffmpeg to burn the original timecode into the picture.
If i open the original file in QuickTime Player we can see it displays the true timecode on the far left :
I can also see that ffprobe is able to see the metadata when i run the following :
Command :
ffprobe -i test.mov -show_streamsAbbreviated Result :
Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'test.mov':
Metadata:
major_brand : qt
minor_version : 537199360
compatible_brands: qt
creation_time : 2018-11-05T14:20:51.000000Z
timecode : 09:59:53:00
Duration: 00:16:37.64, start: 0.000000, bitrate: 1680 kb/sSo i can see that ffprobe is able to determine the start timecode of the file in its metadata results. The question is how to i pass that information into an ffmpeg command so that the timecode seen by ffprobe is what gets used when i convert the file for timecode burn-in ?
An example of a standard burnt in timecode command would be this :
ffmpeg -i test.mov -vcodec libx264 -cmp 22 -vf
"drawtext=fontfile=DroidSansMono.ttf : timecode=’09:59:53:00’ : r=25 :
x=(w-tw)/2 : y=h-(2*lh) : fontcolor=white : box=1 : boxcolor=0x00000099"
-y test_bitc.movThe only problem there though is that i’ve had to manually put the timecode in myself. I want the command to use the existing timecode metadata as the timecode input value so the same command can be used on multiple files.
Does anyone know how to do this ?
