video-streaming

I need to develop a video streaming server which would stream a live video to multiple users. It needs to support the following "video" sources for the re-stream server: web-camera surveillance camera (already supports MJPG stream) scanner I understand that I would need a different driver for adding support to each video input device. I also need to support the video-display in: web-browsers Mozilla Firefox 3.6 Internet Explorer 8 desktop applications developed in C++ / QT 4.6 My questions: What would be a good video output format that can be used to support the required browsers/applications?

I am trying to stream my webcam over rtsp and open the stream using android. I managed to get the first part working (rtsp stream) using ffserver and ffmpgeg. Here is my ffserver.conf file : HTTPPort 8000 RTSPPort 8001 HTTPBindAddress 192.168.1.74 RTSPBindAddress 192.168.1.74 MaxClients 100 MaxBandwidth 10000 NoDefaults <Feed witty.ffm> File /tmp/witty.ffm FileMaxSize 20M </Feed> <Stream witty.mov> Feed witty.ffm Format rtp VideoSize 640x480 VideoQMin 1 VideoQMax 20 VideoFrameRate 30 VideoBitRate 500 AVOptionVideo flags +global_header VideoCodec libx264 AVPresetVideo baseline NoAudio </Stream>

I am trying to stream video from a IP Cam to my my Wordpress site. I would like my stream to be available via common devices Windows, Mac, Android and IOS. Currently I am using VLC to stream,but I can only get a flash stream to work but I would like to do FLV, MP4 and webm. What player should I use to display the MP4 and webm video on the site? Also I don't think the calls to VLC are correct cause I can't open the MP4 and webm stream in VLC on another computer, but I can open the flv stream. VLC Script: cd "C:\Program Files (x86)\VideoLAN\VLC" vlc -vvv -I dummy http://IP/cgi/mjpg/mjpg.cgi

It is possible to split file into many parts.Is it possible every part encode and after that join them again? The idea is to encode one video on more computers. In .NET Thank you You can call ffmpeg.exe from your c# code to accomplish this. There are also some libraries that are available to accomplish this. Take a look at DirectShow .NET - it has some functionality for video capture and editing, although you still need to be familiar with general processing algorithms and methods. These two articles can probably point you in the right direction: Stephen Toub's DVR-MS article. Covers reading

I have to stitch the images captured from many (9) cameras. Initially, I tried to capture the frames from 2 cameras with rate 15 FPS. Then, I connected 4 cameras (I also used externally powered USB hub to provide enough power) but I could only see only one stream. For testing, I used the following script: import numpy as np import cv2 import imutils index = 0 arr = [] while True: cap = cv2.VideoCapture(index) if not cap.read()[0]: break else: arr.append(index) cap.release() index += 1 video_captures = [cv2.VideoCapture(idx) for idx in arr] while True: # Capture frame-by-frame frames = []

I am trying to develop a hls player on android devices, and i have some test-streams i can play with. A problem i have is that the HLS stream just "stops", freezes at some random locations, it could be after 1 minute, or after 20. The error i get is: 11-20 14:14:10.484: W/AudioSystem(18531): AudioFlinger server died! 11-20 14:14:10.484: W/IMediaDeathNotifier(18531): media server died and 11-20 14:14:10.484: E/MediaPlayer(18531): Error (100,0) I've got basically no idea on how to prevent or restart the stream if this is happening. I don't even know why it happens. So if someone could answer
