    Modules spécifiques
    Pour la configuration d’Apache, il est conseillé d’activer certains modules non spécifiques à MediaSPIP, mais permettant d’améliorer les performances : mod_deflate et mod_headers pour compresser automatiquement via Apache les pages. Cf ce tutoriel ; mode_expires pour gérer correctement l’expiration des hits. Cf ce tutoriel ;
    Il est également conseillé d’ajouter la prise en charge par apache du mime-type pour les fichiers WebM comme indiqué dans ce tutoriel.

  • How can I extract the characteristics of multimedia video stream while the video is streaming ?

    10 mai 2021, par Kai

    I have built adaptive video streaming ,DASH, over SDN network and was wondering if I can get some video characteristics while the video is streaming. I have used youtube_dl and was able to get the received video after the completion of the stream however, I want to get the video characteristics such as (stream size, bitrate, frame rate, resolution and etc.) while streaming. I hope that you can provide me with a script to extract and generate a file that contains such information.

    


  • batch ffmpeg conversion (aspect, crop, and concatenate) and naming based on subfolder

    3 avril 2015, par hordor

    TYIA for any help !

    Seems I have a somewhat complicated, multi-step process. If you can help any part of it that would be appreciated.

    What I hope to accomplish

    1. Example of folder/file is here : https://mega.co.nz/#F !RJRWRLTJ !c6b-z3Vl-Tlh0uGbCflx7Q
    2. I have many subfolders that each contain 7 files from a DVD (originally PAL-encoded I think). I only care about the VTS_01_1.VOB AND VTS_01_2.VOB files. The two files together are one match
    3. The videos are stretched (from 4:3 to 16:9) and letterboxed. I want to undo that
    4. The future title of the final MP4 video should be the name of the folder
    5. BONUS : title of the video should also include the folder before it (e.g. "Friday H2 G1 CAN - BEL.mp4")

    I’d like to do this via batch file because there are a lot of folders.

    What I have done :

    dir/b/s *.vob | findstr /v VIDEO | findstr /v 01_ >list.txt
    

    
@echo off
    
for %%i in list.txt 
    
do   
    
  ffmpeg -i VTS_01_1.VOB -aspect 4:3 "%%~pi\v1step1.mp4"
    
  ffmpeg -i vob1.mp4 -vf "crop=704:432:10:72" "%%~pi\v1step2.mp4"
    
  ffmpeg -i vob11.mp4 -c copy "%%~pi\v1step3.ts"
    
  ffmpeg -i VTS_01_2.VOB -aspect 4:3 "%%~pi\v2step1.mp4"
    
  ffmpeg -i vob2.mp4 -vf "crop=704:432:10:72" "%%~pi\v2step2.mp4"
    
  ffmpeg -i vob22.mp4 -bsf h264_mp4toannexb -c copy "%%~pi\v2step3.ts"
    
  ffmpeg -i "concat:v1step3.ts|v2step3.ts" -c copy file.mp4 "%%~pi\Match.mp4"
    

    
@echo on
    
pause

    Problem with current code

    1. Doesn’t start converting (can’t see error message either)
    2. Doesn’t have the file naming that I want
    3. A lot of steps in conversation - can that be simplified ?
    4. Not sure why it wanted the -bsf command for the second conversion but not the first

    Apologies if I’d made basic mistakes. I’m a big newbie and just to get this far has taken me hours of research. Thanks again !
