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.

FFmpeg batch file - combine individual set files with randomized selection from another set of files
4 août 2018, par SiampuI need to combine a specific set of files with a randomized selection from another set of files ; for more specific context, voice clips followed by a randomized walky-talky beep. At the moment, I’ve managed to assemble this so far from searching around :
setlocal EnableDelayedExpansion
cd beeps
set n=0
for %%f in (*.*) do (
set /A n+=1
set "file[!n!]=%%f"
)
set /A "rand=(n*%random%)/32768+1"
cd ..
for %%A IN (*.ogg) DO ffmpeg -y -i radio_beep.wav -i "%%A" -i "beeps\!file[%rand%]!" -filter_complex "[0:a:0][1:a:0][2:a:0]concat=n=3:v=0:a=1[outa]" -map "[outa]" "helper\%%A"At the moment, this will only run the randomization once and use that selection for every file. How can I have it do the randomization for each .ogg in the folder, and get that into FFmpeg as an input ?

FFMPEG zoompan only applies and shows 3 images out of the many
26 mai 2018, par Sanjyot ShahI am trying to generate a video from images using FFMPEG 4.0 windows built on AWS windows instance using PHP.
$command2="ffmpeg -r 1/5 -i https://<path>/$images%d.jpg -c:v libx264 -r 5 -t $total_video_time -y ".trim($video_name)." -i http://<path>/$audio ";
</path></path>The above generates the correct video output with all the input images (50 in this case) but without the zoompan effect on the images.
Now I try to add the zoompan effect for the images using -
$command2="ffmpeg -r 1/5 -i https://<path>/$images%d.jpg -filter_complex zoompan=z='zoom+0.002':d=25*4:s=1280x800 -pix_fmt yuv420p -c:v libx264 -r 5 -t $total_video_time -y ".trim($video_name)." -i http://<path>/$audio ";
</path></path>This will only pick up the first 3 images and apply the zoompan to the first two images or so.
Can you please help me with this issue ? Any inputs, pointers are welcome too.
