  • Amélioration de la version de base

    13 septembre 2013

    Jolie sélection multiple
    Le plugin Chosen permet d’améliorer l’ergonomie des champs de sélection multiple. Voir les deux images suivantes pour comparer.
    Il suffit pour cela d’activer le plugin Chosen (Configuration générale du site > Gestion des plugins), puis de configurer le plugin (Les squelettes > Chosen) en activant l’utilisation de Chosen dans le site public et en spécifiant les éléments de formulaires à améliorer, par exemple select[multiple] pour les listes à sélection multiple (...)

  • Emballe médias : à quoi cela sert ?

  • Using batch process to encode multiple files one at a time with ffmpeg

    10 octobre 2014, par Tom Drake

    Total beginner here, likely asking for help on something (hopefully) very easy to implement.

    I have a drop folder set up to trigger a batch process that will encode any videos contained therein to 5 different formats using FFMPEG. It also creates a text file containing the files name which I then use in a separate php/api process to upload the videos to the internet.

    The process works perfectly when just the one video is dropped into the drop folder. However, as soon as there are two or more then the process comes unstuck.

    Here’s an example of one of the ffmpeg scripts the batch file runs :

    for %%a in ("C:\live\dropfolder\transcode\*.*") do ffmpeg\ffmpeg -i "%%a" (encoding settings) "C:\live\dropfolder\output\%%~na.mp4"
    
pause
    
for %%g in (C:\live\dropfolder\output\*.mp4) do echo %%~nxg > C:\live\dropfolder\filename\filename_format.txt

    So when there are 2 or more files, the filename that gets generated by that echo might be for File A, while the transcoding session might have been for File B.

    Ideally I’d like to have the whole process finish transcoding the first video - including generating the text files for each format - before returning to the beginning of the process for the next video in the drop folder.

    How do I achieve this ? Any suggestions would be greatly appreciated.

    Thanks !

  • Decode MP4 h264 RTP Video Stream C++

    26 juin 2022, par laurrrr

    I want to send a mp4 video which is h264 encoded to another C++ Application and get raw video data.

    


    I'm sending rtp packets using ffmpeg using following command :

    


    ffmpeg -re -i video.mp4  -pix_fmt rgb24  -vcodec libx264 -b:v 10506k -bufsize 64000k -r 30.0 -f mp4 -f rtp rtp://192.168.1.101:4500?pkt_size=1316 


    


    and this is ffmpeg output after video has been played :

    


    Output #0, rtp, to 'rtp://192.168.1.101:4500?pkt_size=1316':

    After streaming starts I get 1 rtp packet len 25 , 1 rtp packet len 5 and 1 rtp packet len 760. After I received the packet with len 760 I get this message :

    


    [rtplib][rtpPkt_Handler]Found a key frame at ts 4178129015


    


    Can someone please explain to me what this rtp messages with len 25,5 and 760 means and what key frame means in this context ?

    


    Also I have rtp packets of size 5 and 25 in the middle of transmission.

    


    As you can see ffmpeg is saying 1802 frames were sent and Total packets received in C++ Application is 1819 because I receive 8 rtp packets of len 25, 8 rtp packets of len 5 and 1 rtp packet of size 760. If we substract this, it's exactly 1802 frames.

    


    My questions would be :

    


    How to get frame raw pixel data based on rtp packets payload data I receive ? eg. 1280x720 3 Channels ( thats the mp4 video resolution )

    


    Can someone tell me what those packets of len 25,5,760 on the beggining means and packets of len 25,5 in the middle of transmission means ?

    


    Thanks in advance !!!

    


  • FFMPEG image sequence to video using 1 fps

    26 septembre 2022, par Ponzifex

    I want to make a slideshow type of video using 25 images starting from 00000.jpg to 00025.jpg.
I have used the following command, but the video ended up having 2 frames total.

    


    ffmpeg -i ./test/%5d.jpg -r 1 -crf 10 test.webm


    


    What I want to achieve is to have a 25 seconds long video using all the 25 images. I can achieve this using a video editor, but I want to automate this process using ffmpeg in the command line, because I may have much more images to process, the above is just an example. I got downvotes for this question, but not a single comment.

    


    Please let me know how to do this using ffmpeg.
