Installation en mode ferme
4 février 2011, parLe mode ferme permet d’héberger plusieurs sites de type MediaSPIP en n’installant qu’une seule fois son noyau fonctionnel.
C’est la méthode que nous utilisons sur cette même plateforme.
L’utilisation en mode ferme nécessite de connaïtre un peu le mécanisme de SPIP contrairement à la version standalone qui ne nécessite pas réellement de connaissances spécifique puisque l’espace privé habituel de SPIP n’est plus utilisé.
Dans un premier temps, vous devez avoir installé les mêmes fichiers que l’installation (...) -
Multilang : améliorer l’interface pour les blocs multilingues
18 février 2011, parMultilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela. -
HTML5 audio and video support
13 avril 2011, parMediaSPIP uses HTML5 video and audio tags to play multimedia files, taking advantage of the latest W3C innovations supported by modern browsers.
The MediaSPIP player used has been created specifically for MediaSPIP and can be easily adapted to fit in with a specific theme.
For older browsers the Flowplayer flash fallback is used.
MediaSPIP allows for media playback on major mobile platforms with the above (...)

How to mirror swscale PIX_FMT_YUYV422
31 janvier 2012, par supergI'm trying to mirror libswscale PIX_FMT_YUYV422-type image horizontally. Using simple loop for each line with 16-bits per pixel results in having colors wrong, for example blue objects are orange. Here is my code :
typedef unsigned short YUVPixel; // 16 bits per pixel
for (int y = 0; y < outHeight; y++)
{
YUVPixel *p1 = (YUVPixel*)pBits + y * outWidth;
YUVPixel *p2 = p1 + outWidth - 1;
for (int x = 0; x < outWidth/2; x++) // outWidth is image width in pixels
{
// packed YUV 4:2:2, 16bpp, Y0 Cb Y1 Cr
unsigned short tmp;
tmp = *p1;
*p1 = *p2;
*p2 = tmp;
}
}Then I tried redefining YUVPixel as 32-bit type and modifying my loop accordingly. This results in correct colors, but looks like neighboring pixels are swapped. Any ideas, I'm totally lost with this ?

I can't get my backend working with frontend in production but in local environment [duplicate]
3 août 2024, par YouareGrouseChrisThis is the frontend code :


import React, { useState } from 'react';
import axios from 'axios';
import fileDownload from 'js-file-download';

function HomePage() {
 const [url, setUrl] = useState('');
 const [filename, setFilename] = useState('');

 const handleSubmit = async (e) => {
 e.preventDefault();
 try {
 const response = await axios.post('https://api-lnp5.onrender.com/api/download', { url, filename }, { responseType: 'blob' });
 fileDownload(response.data, filename);
 console.log(response.data); // handle the response as needed
 } catch (error) {
 console.error(error);
 }
 };

 return (
 <div classname="flex flex-col items-center justify-center h-screen overflow-hidden">
 <h1 classname="text-3xl font-bold mb-6">Download Reddit video!!!</h1>
 <form classname="flex flex-col items-center">
 <label classname="mb-4">
 <div classname="text-lg mb-4 inline-block">Video URL:</div>
 <div>
 <input type="text" value="{url}" />> setUrl(e.target.value)} required 
 className="border px-3 py-2 rounded focus:outline-none focus:ring focus:border-blue-300 w-96"/>
 </div>
 </label>
 <label classname="mb-4">
 <div classname="text-lg mb-4 inline-block">Filename:</div>
 <div>
 <input type="text" value="{filename}" />> setFilename(e.target.value)} required 
 className="border px-3 py-2 rounded focus:outline-none focus:ring focus:border-blue-300 w-96"/>
 </div>
 </label>
 <button type="submit" classname="bg-blue-500 text-white px-4 py-2 rounded hover:bg-blue-600">Download</button>
 </form>
 </div>
 );
}

export default HomePage;


This is the backend code using python fastapi :


from fastapi import FastAPI, HTTPException

from fastapi.responses import FileResponse
from fastapi.middleware.cors import CORSMiddleware
from pydantic import BaseModel
import requests
import json
import subprocess
import os

app = FastAPI()

origins = [
 "https://videodownload-frontend.onrender.com", # replace with the origin of your frontend
]

app.add_middleware(
 CORSMiddleware,
 allow_origins=["*"],
 allow_credentials=True,
 allow_methods=["*"],
 allow_headers=["*"],
)

class Video(BaseModel):
 url: str
 filename: str


def get_unique_filename(filename):
 counter = 1
 base_filename, extension = os.path.splitext(filename)
 unique_filename = filename

 while os.path.isfile(unique_filename):
 unique_filename = f"{base_filename}({counter}){extension}"
 counter += 1

 return unique_filename

@app.post("/api/download")
async def download_video(video: Video):
 url = video.url
 filename = get_unique_filename(video.filename)

 url += '.json'
 response = requests.get(url, headers={'User-agent': 'Mozilla/5.0'})

 if response.status_code != 200:
 raise HTTPException(status_code=404, detail="Video not found")

 json_response = json.loads(response.text)
 video_url = json_response[0]["data"]["children"][0]["data"]["secure_media"]["reddit_video"]["fallback_url"]
 audio_url = video_url.rsplit('/', 1)[0] + '/DASH_audio.mp4'

 video_response = requests.get(video_url, stream=True)
 audio_response = requests.get(audio_url, stream=True)

 with open('video_temp.mp4', 'wb') as f:
 for chunk in video_response.iter_content(chunk_size=1024 * 1024):
 if chunk:
 f.write(chunk)
 if audio_response.status_code == 200:
 with open('audio_temp.mp4', 'wb') as f:
 for chunk in audio_response.iter_content(chunk_size=1024 * 1024):
 if chunk:
 f.write(chunk)
 subprocess.run(['ffmpeg', '-i', 'video_temp.mp4', '-i', 'audio_temp.mp4', '-c', 'copy', filename])
 else:
 os.rename('video_temp.mp4', filename)

 return FileResponse(filename, media_type='application/octet-stream', filename=filename)


I deployed the fastapi by docker to Render. When I start the frontend development server, I could communicate with the backend without problems. But when I deployed both frontend and backend to Render, it shows always the CORS policy




Why is it ? if I could communicate with backend when starting local development server, it should be not related to backend.


This is URL to my frontend : https://videodownload-frontend.onrender.com/


Thank you !


I tried reconnect and restart the web service, also I tried to add CORS in fastapi. The api works fine with local server opened up. What should I do to debug ? thank you

How to add padding on a video with text in foreground using ffmpeg
25 août 2016, par g13I want to add padding to video clip according to width and height of the text I input. The sentence should be able to break relative to video width automatically.
For padding I use :
ffmpeg -i d:\video.mp4 -vf pad=600:700:0:100:blue d:\videooutput.mp4For text :
ffmpeg -i d:\videooutput.mp4 -vf "drawtext=fontfile=/windows/fonts/BebasNeue.otf:text='Sed felis eros, ornate ut cursus a, imperdiet sit amet purus.':fontsize=20:fontcolor=white:x=0:y=0" d:\videooutput2.mp4How to do achieve this in a single command ?
The required result should be like this :
