Demande de création d’un canal
12 mars 2010, parEn fonction de la configuration de la plateforme, l’utilisateur peu avoir à sa disposition deux méthodes différentes de demande de création de canal. La première est au moment de son inscription, la seconde, après son inscription en remplissant un formulaire de demande.
Les deux manières demandent les mêmes choses fonctionnent à peu près de la même manière, le futur utilisateur doit remplir une série de champ de formulaire permettant tout d’abord aux administrateurs d’avoir des informations quant à (...) -

How to fix ffmpeg's offical tutorials03 bug that sound does't work well ?
31 janvier 2019, par xiaodaiI want to learn to make a player with ffmpeg and sdl. The tutorial I used is this.[http://dranger.com/ffmpeg/tutorial03.html] Though I have resampled the audio from decode stream, the sound still plays with loud noise.
I have no ideas to fix it anymore.
I used the following :
- the latest ffmpeg and sdl1
- Visual Studio 2010
// tutorial03.c
// A pedagogical video player that will stream through every video frame as fast as it can
// and play audio (out of sync).
//
// This tutorial was written by Stephen Dranger (dranger@gmail.com).
//
// Code based on FFplay, Copyright (c) 2003 Fabrice Bellard,
// and a tutorial by Martin Bohme (boehme@inb.uni-luebeckREMOVETHIS.de)
// Tested on Gentoo, CVS version 5/01/07 compiled with GCC 4.1.1
//
// Use the Makefile to build all examples.
//
// Run using
// tutorial03 myvideofile.mpg
//
// to play the stream on your screen.

ffmpeg massive error spamming from FritzBox rtsp stream
19 février 2019, par itzaiiroIm trying to offer a rtsp live TV stream via rtmp to my family, since the Fritz Box (which is offering the stream) has only 4 tuners -> at most 4 streams can be watched simultaneously.
Im using ffmpeg to prepare the stream as dash stream and send it to my rtmp nginx. When i run ffmpeg im experiencing heavy image and audio artifacts in the final stream and error spams of doom in the console. I couldn’t find anything specific to my case on google. I read on the internet that AVM barely implemented the rtsp protocoll enough to get it to work with vlc mediaplayer.launch param :
ffmpeg -i "rtsp://192.168.178.1:554/?avm=1&freq=114&bw=8&msys=dvbc&mtype=256qam&sr=6900&specinv=1&pids=0,16,17,18,20,260,543,544,546,548,1621" -sn -vcodec libx264 -vprofile baseline -acodec aac -strict -2 -b:v 500k -minrate 500k -maxrate 500k -bufsize 1000k -g 60 -s 640x360 -f flv rtmp://192.168.178.15/dash/pro_sieben_low -sn -vcodec libx264 -vprofile baseline -acodec aac -strict -2 -b:v 1500k -minrate 1500k -maxrate 1500k -bufsize 3000k -g 60 -s 1280x720 -f flv rtmp://192.168.178.15/dash/pro_sieben_med -sn -vcodec libx264 -vprofile baseline -acodec aac -strict -2 -b:v 5000k -minrate 5000k -maxrate 5000k -bufsize 10000k -g 60 -s 1920x1080 -f flv rtmp://192.168.178.15/dash/pro_sieben_highffmpeg output (windows) :
stored in pastebin
https://pastebin.com/p4HAyBi5Is there anyway to get this under control ? The original stream is running good with vlc, but its unwatchable after its out of ffmpeg.
Edit :
I was running/testing this on my windows machine, but my target for this task is a ubuntu 16.04 so here ffmpeg on target with pthread support :ffmpeg -i "rtsp://192.168.178.1:554/?avm=1&freq=114&bw=8&msys=dvbc&mtype=256qam&sr=6900&specinv=1&pids=0,16,17,18,20,260,543,544,546,548,1621" -sn -vcodec libx264 -vprofile baseline -acodec aac -strict -2 -b:v 500k -minrate 500k -maxrate 500k -bufsize 1000k -g 60 -s 640x360 -f flv rtmp://192.168.178.15/dash/pro_sieben_low -sn -vcodec libx264 -vprofile baseline -acodec aac -strict -2 -b:v 1500k -minrate 1500k -maxrate 1500k -bufsize 3000k -g 60 -s 1280x720 -f flv rtmp://192.168.178.15/dash/pro_sieben_med -sn -vcodec libx264 -vprofile baseline -acodec aac -strict -2 -b:v 5000k -minrate 5000k -maxrate 5000k -bufsize 10000k -g 60 -s 1920x1080 -f flv rtmp://192.168.178.15/dash/pro_sieben_high
