Le plugin : Podcasts.
14 juillet 2010, parLe problème du podcasting est à nouveau un problème révélateur de la normalisation des transports de données sur Internet.
Deux formats intéressants existent : Celui développé par Apple, très axé sur l’utilisation d’iTunes dont la SPEC est ici ; Le format "Media RSS Module" qui est plus "libre" notamment soutenu par Yahoo et le logiciel Miro ;
Types de fichiers supportés dans les flux
Le format d’Apple n’autorise que les formats suivants dans ses flux : .mp3 audio/mpeg .m4a audio/x-m4a .mp4 (...) -

Send inputs to a process (ffmpeg) using python
10 mai 2023, par NoddyI am trying to program a custom screen recording functionality, but I have problems sending input to a process.


To achieve this I use
ffmpeg. The idea is that I have two scripts A and B

A : Begin recording - create a
ffmpegsubprocess that records the screen and writes the process id (pid) to a file

B : Stop the recording - Read the pid from the file and send a 'q' input to the process to stop the recording


This is my code :


A :


import shlex
import subprocess
import time
import datetime

# Variables
success = True
flowName = "workflow1"

# Get current date and time
now = datetime.datetime.now()

formatted_date = now.strftime("%Y-%m-%d %H:%M:%S")

folderDestination = f"C:\\Users\\MadPe\\Desktop\\pipRec\\workFlows\\{flowName}\\"

formatted_date = formatted_date.replace(":",".").replace(" ","_")

fileName = folderDestination + formatted_date + ".mp4"

ffmpegPath = r"C:\Users\MadPe\Desktop\pipRec\ffmpeg\bin\ffmpeg.exe"

command = shlex.split(f'"{ffmpegPath}" -f gdigrab -framerate 30 -offset_x 0 -offset_y 0 -video_size 1920x1080 -i desktop -y "{fileName}"')
process = subprocess.Popen(command, stdin=subprocess.PIPE)

pid = process.pid
startTime = time.time()

with open("filename.txt", "w") as file:
 file.write(str(pid))

#process.stdin.write(b'q\n') #-- this is how I stop the recording
#process.stdin.flush() #-- but I want to do this from another script


B :


import psutil

# Stop recording and kill Process
with open("filename.txt", "r") as f:
 pid = int(f.read().strip())

if psutil.pid_exists(pid):
 process = psutil.Process(pid)
 process.stdin.write(b'q\n')
 process.stdin.flush()
else:
 print(f"Process with PID {pid} is not running.")


however, when I try to stop the running process I get this error :




I hope some of you may be able to spot what I am doing wrong.
also if I comment in the last two lines in A it will make the recording stop, but I want to be able to do this from running B

Hello. I'd like to play a video on my app on android, I tried with videoplayer, it works but doesn't load the video simply open theUI but not thevideo
26 octobre 2022, par AbdulI'd like to play a video on my app on android, I tried with videoplayer, it works but doesn't load the video ( simply open the UI but not the video).


I found out i may need ffpyplayer so I changed buildozer requirements :
requirements = python3,kivy, android,ffpyplayer


but buildozer failed to build apk when i added ffpyplayer and ffmpeg in buildozer.spec file in requirement.

Can i limit CPU usage of my Script ? Raspberry pi cpu crashing - rebooting [duplicate]
5 novembre 2024, par Mateus CoelhoI have a script, in python, that converts a video of 11mb, 30fps, 1080p. the code puts 4 imagens into it, with overlay, and rotates 90.
When i run the script into the raspberry pi, it goes off CPU, all the 4 threads go to 100% and it suently reboots.


Raspberry pi 4 b 4gb


I want to limit the cpu to like 60% to the script... its not a problems to be longer in time.


import subprocess
import sys
import time
import psutil
import os

def overlay_images_on_video(input_file, image_files, output_file, positions, image_size=(100, 100), opacity=0.7):

 overlay_images_on_video(input_video, image_files, output_video, positions, image_size=(250, 250), opacity=0.8)


EDITED :


The 4 cores of the CPU goes to 100%, i can see in another ssh terminal via htop, and it sudently reboots.
I have other 9 scripts running on the back, 6 ffmpeg stremas and 3 others to caputre the videos. When i add this logic to the other 3 that captures the video or i try to run directly one time, it reboots
