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 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 ?

r210enc.c : Simplify and never store more than 10 bits.
27 décembre 2014, par Reimar Döffingerr210enc.c : Simplify and never store more than 10 bits.
The r10k and avrp decoders would previously store 12 bit precision
for the blue channel, which is inconsistent and probably not a
desirable behaviour.
Now the 2 unused extra bits are set to 0.
This is possibly not ideal either as RGBA1010102 format has the same
layout but stores alpha in these bits, thus explicitly setting them
to 1 might be preferable.Signed-off-by : Reimar Döffinger <Reimar.Doeffinger@gmx.de>
