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 (...) -
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.

Streaming raw sound with FFMPEG
30 juin 2020, par Dr_ClickI'm using the ffmpeg library to decode / encode audio in JAVA, using the Process objets. The aim is to got the raw datas decoded by ffmpeg in my JAVA code and then, to send them back to ffmpeg to generate a stream or create a file.



As JAVA sounds only allow wav audio datas, I made a first try with this command line :



ffmpeg -i http://199.180.75.118:80 -acodec pcm_s16le -ar 44100 -ac 2 "/home/dr_click/montest.wav"



It works. But, my goal is to get the frames on the fly and not a file. I thought about using a pipe but it seems it will work only with Linux and not with Windows (and no idea for MacOS)
So, I'd prefer to stream locally a wav file and to catch it with JAVA into a AudioInputStream.



I wrote this command :



ffmpeg -re -i http://199.180.75.118:80 -acodec pcm_s16le -ar 44100 -ac 2 -f rtp rtp://127.0.0.1:1234



It semms to work on the server side. But, when I enter the below command line on the server side :



ffplay rtp://127.0.0.1:1234



It doesn't work at all. I got this error :



- 

- [rtp @ 0x7f29c8000b80] Unable to receive RTP payload type 97 without an SDP file describing it





If I try the couple :



ffmpeg -i http://199.180.75.118:80 -acodec pcm_s16le -ar 44100 -ac 2 -f rtp -sdp_file /home/dr_click/audio.sdp rtp://127.0.1.1:1234



and



ffplay /home/dr_click/audio.sdp



I got the following error :



- 

- [rtp @ 0x7f7d00008040] Protocol 'rtp' not on whitelist 'file,crypto' ! if





And if I finally try :



fmpeg -protocol_whitelist file,http,rtp,tcp -i http://199.180.75.118:80 -acodec pcm_s16le -ar 44100 -ac 2 -f rtp -sdp_file /home/dr_click/audio.sdp rtp://127.0.1.1:1234



I still get the same error.



Which point do I miss to stream locally some raw datas and catch them back in the AudioInputStream ?



Thank you for all your replies.

I tried updating ffmpeg and moviepy. I even tried different versions but to no avail. The video clips are not corrupted as I checked.


This part of the code is responsible for generating the videos :


def generate_video(audio_path):
 input_folder = '/home/AlisterK/video_clips' # Replace with your folder path
 output_file = '/home/AlisterK/output_combined_video.mp4'
 clip_duration = 3 # Duration of each clip in seconds
 num_clips = 10 # Number of video clips to select and combine

 width = 1080 # Replace with your desired width
 height = 1920 # Replace with your desired height

 video_clips = random_files_in_folder(input_folder, '.mp4', num_clips)

 clips = [VideoFileClip(os.path.join(input_folder, clip_file)).subclip(0, clip_duration) for clip_file in video_clips]
 standardized_clips = [clip.resize((width, height)) for clip in clips] # Ensure consistent resolutions

 final_clip = concatenate_videoclips(standardized_clips)

 final_audio = AudioFileClip(audio_path)
