  • Ajouter notes et légendes aux images

    7 février 2011, par

    Pour pouvoir ajouter notes et légendes aux images, la première étape est d’installer le plugin "Légendes".
    Une fois le plugin activé, vous pouvez le configurer dans l’espace de configuration afin de modifier les droits de création / modification et de suppression des notes. Par défaut seuls les administrateurs du site peuvent ajouter des notes aux images.

  • How can I burn in .ass file and a watermark to a video file using ffmpeg simultaneously ?

    9 mai 2023, par Candour

    I want to add subtitles and a watermark to a video using ffmpeg. For now I'm using Handbrake to burn in the subtitles and later I execute an ffmpeg command to add a watermark from png file.

    


    The watermark command :

    


    ffmpeg -i F:\ffmpeg\bin\video.mp4 -i F:\ffmpeg\bin\logo.png -filter_complex "[1]format=rgba,colorchannelmixer=aa=0.4[logo];[logo][0]scale2ref=oh*mdar:ih*0.07[logo][video];[video][logo]overlay=(main_w-overlay_w)-10:10" output.mp4


    


    I was wondering how a command would look like if I wanted to skip the Handbrake part and burn the subtitles in directly in the same command as the watermark.

    


    Well, I understand the basics of ffmpeg commands and I tried to combine the commands but i got lost. I think the third input would be needed that somehow also goes in the overlay filter. I really hope someone can help

    15 octobre 2019, par mrlonely

    I am not able to play m3u8 link for some specific files.

    Details are as follows :

    ffmpeg  -i low_30.mp3 -codec:v libx264 -b:v  64k -maxrate 64k -bufsize 64k -vf  scale=-2:480 -threads 0 -vsync 2 -pix_fmt yuv420p -codec:a aac -b:a  64k  -hls_list_size 0 abc.m3u8

    Error :
