Qualité du média après traitement
21 juin 2013, parLe bon réglage du logiciel qui traite les média est important pour un équilibre entre les partis ( bande passante de l’hébergeur, qualité du média pour le rédacteur et le visiteur, accessibilité pour le visiteur ). Comment régler la qualité de son média ?
Plus la qualité du média est importante, plus la bande passante sera utilisée. Le visiteur avec une connexion internet à petit débit devra attendre plus longtemps. Inversement plus, la qualité du média est pauvre et donc le média devient dégradé voire (...) -

ffmpeg Error : Pattern type 'glob' was selected but globbing is not support ed by this libavformat build
14 septembre 2017, par Aryan NaimI’m trying to convert group of ".jpg" files acting as individual frames into 1 single mpeg video ".mp4"
Example parameters i used :
frame duration = 2 secs
frame rate = 30 fps
encoder = libx264 (mpeg)
input pattern = "*.jpg"
output pattern = video.mp4Based on ffmpeg wiki instructions at (https://trac.ffmpeg.org/wiki/Create%20a%20video%20slideshow%20from%20images), I issued this command :
ffmpeg -framerate 1/2 -pattern_type glob -i "*.jpg" -c:v libx264 -r 30 -pix_fmt yuv420p video.mp4
But I’m getting this error :
[image2 @ 049ab120] Pattern type 'glob' was selected but globbing is not
supported by this libavformat build *.jpg: Function not implementedWhich probably means the API pattern matching commands for my build/version have changed. By the way this my windows 32bit ffmpeg download build (
ffmpeg-20150702-git-03b2b40-win32-static
).How can I choose a group of files using pattern matching using ffmpeg ?

Using FFMPEG Video Compression in Windows Batch files [closed]
21 juillet 2020, par TrainNutterI am having some trouble with using FFMPEG in a Windows (10) Batch file. What I am trying to do is to get a Batch file to compress all video files in a folder bu running 1 batch file execution (Per folder) so that I could say run it over night and have 1 folder with a load of video filed compressed down from say 500MB RAW to a much smaller size compressed.


The code I have put together below.


for %%i in (*.mp4) do ffmpeg -i "%%i" vcodec libx265 -crf 24 -o "%%~ni.mp4"



However cmd says the following error :
Unable to find output


I don't understand as the
-o "%%~ni.mp4"
bit is clearly an output. Some helo would be greatly appreciated

FFMPEG disabled automatic compression file
2 novembre 2017, par HenrykVIIIHow to disable FFMPEG in its own compressed file compression, which does not come from the program code. This is when the file is merged (as the first task) or file stabilization (as the first task). I lose on file quality by reducing itself from 16k to 7k birate files (in parts) input.
So, without loss, I have to merge files or stabilize them so that they do not change ?
I will add that the effect does not affect every film - only the majority. None of which come out of a duel completely and eg for 16.2k input birate have output 16k birate .. What is no visible loss.
But the loss from 16k to 7k is already visible on the details and especially the movies shot at night and in the wrong light.
I enclose the wrapper code c # :
The same situation occurs when the first task is to combine files :Can anyone help ?? : (((
