video-streaming

I have a multi-cast UDP Video stream that I need my OPenCV (Emgu ) 2.4.x app to capture and process ("client"). On the client, I can capture the stream using VLC (udp://xx.yy.zz.aaa:1234, However the my app fails to capture this udp stream. My code is quite simple ( Capture cap = new Capture ("udp://@212.1.1.1:1234"); p.s. I have tried with and 2/o the @ also tried rtp on that address. No luck :-/ Does OpenCV directly allow "capture" of UDP streams? or do I need to run VLC on the client to re-stream the video as rtp or http or some other....? Thanks. I finally figured this out and sharing in

I need to display a ip camera stream in an html video tag, i have figured out how to transcode to a file from the rtsp stream like this ffmpeg -i "rtsp://user:password@ip" -s 640x480 /tmp/output.mp4 now i need to be able to be able to live stream the rtsp input in a video tag like this <video id="video" src="http://domain:port/output.mp4" autoplay="autoplay" /> I was trying to do something like this in my server (an ubuntu micro instance on amazon) in order to reproduce the video in the video tag but didn't work ffmpeg -i "rtsp://user:password@ip" -s 640x480 http://localhost:8080/stream.mp4

I'm using classic VideoView implementation to play video on Android. Same mp4 file url works fine on HTC Desire. However it doesn't work on Samsung devices. Samsung Galaxy S1 and Samsung Galaxy Tab say: "Cannot play video. Unable to play video. Invalid streaming data" Samsung 5110 says: "Cannot play video. Sorry this video is not valid for streaming to this device" When I looked at mp4 file with a text editor, I realized that mdat tag is before moov . My question is how does it work on HTC whereas it doesn't on samsung devices. And I dont have any chances to change the format of mp4 files, so

I have a DirectShow graph with a "Microsoft DVBT Network Provider", "AVerMedia BDA DVBT Tuner", "AVerMEdia BDA Digital Capture", "Sample Grabber" and "NULL Renderer". These filters are connected. Beside that I also have an "MPEG-2 Demultiplexer" and a "BDA MPEG2 Transport Information Filter", but these two filters are NOT connected! It seems like they have to be here in order to run the graph. When I start the graph, I'm receiving TS data, but no matter what I do, I'm not able to put the tuning request. I can only capture the MUX data from the last tuned frequency with some other application

I think I'm using InputStream incorrectly with a Blackberry 9000 simulator: I found some sample code, http://www.blackberry.com/knowledgecenterpublic/livelink.exe/fetch/2000/348583/800332/1089414/How_To_-_Play_video_within_a_BlackBerry_smartphone_application.html?nodeid=1383173&vernum=0 that lets you play video from within a Blackberry App. The code claims it can handle HTTP, but it's taken some fandangling to get it to actually approach doing so: http://pastie.org/609491 Specifically, I'm doing: StreamConnection s = null; s = (StreamConnection)Connector.open("http://10.252.9.15/eggs.3gp");
