Déploiements possibles
31 janvier 2010, parDeux types de déploiements sont envisageable dépendant de deux aspects : La méthode d’installation envisagée (en standalone ou en ferme) ; Le nombre d’encodages journaliers et la fréquentation envisagés ;
L’encodage de vidéos est un processus lourd consommant énormément de ressources système (CPU et RAM), il est nécessaire de prendre tout cela en considération. Ce système n’est donc possible que sur un ou plusieurs serveurs dédiés.

Is it possible to determine if a subtitle track is imaged based or text based with ffprobe
21 février 2021, par ShexI'm writing a script that burns subtitles into video files to prepare them for a personal stream I'm hosting. I'm having a hard time finding which type of subtitle is used in the file. I use ffprobe to get the files' information, and I can get stuff like the codec type, but I was wondering if there is a way to determine if a subtitle track is image based or text based. I can only think of getting a list of all possible codecs and match the codec type with this list but it would be very useful to have an info somewhere that can tell me "OK this is an image-based subtitle track", as when I burn I cannot use the same filters with ffmpeg to burn image vs. text subtitles.

FFMPEG Windows Batch - Recursive Convert based and settings based on Frame Height
3 avril 2017, par Vahid JamaliSo I’m trying to make a batch file to use FFMPEG to convert around 1000 MP4 video files.
I want to recursively go through these folders, possibly use ffprobe to discover the frame height, and then based on the frame height options (360, 480, 720, or 1080 frame height) give them individually different ffmpeg commands.
I’ve been reading up on various approaches to this just as far as batch processing goes.
So far I’m at this stage :
for %%a in ("*.*") do C:\ffinstall\local64\bin-video\ffmpeg -i "%%a" -c:v libx264 -crf 18 -preset veryslow -tune film -refs 8 -bf 6 -aq-mode 2 -filter_complex "[0:v][1:v]overlay=30:main_h-overlay_h-30,subtitles='D:\add.ass'" -c:a copy "encoded\%%~na.mp4"
pause
Code to discover the frame height :
ffprobe -v error -show_entries stream=height -of default=noprint_wrappers=1 inputfile.mp4
Trying to figure out conditionals and how their syntax is. Also I’m getting a Unable to parse option value "add.ass" as image size error. Which I believe is due to not being to see the subtitle file.
Any suggestions on where I can start ? Thanks for any help.

looking for gui based HLS downloader based on ffmpeg & or better download code [closed]
26 mai 2020, par wahiduzzaman sagarcurrently using ffmpeg for downloading HLS video (m3u8). the code i am using is



ffmpeg -i "www.videoURL.com" -c copy "name name".mp4




its works fine but the problem is it takes a bit more time since I also have to give each video a name where other downloader (video downloadhelper) can automatically get a name from URL. video downloadhelper crashing/stopping a lot so not using it now. also it cant boost speed so i have to run 10-12 simultaneous ffmpeg download with command prompt open to keep the bandwidth use high. which is cluttering the screen and being hard to keep track of.
so is there any better code for faster download or maybe GUI downloader with some feature like auto naming, multi download, etc
