问题 I'm running ffmpeg (Windows 7, 64bit) from command line to get a frame from a RTSP stream (second channel from my DVR): ffmpeg -i "rtsp://xxx.xxx.xxx.xxx:554/user=xxxx&password=xxxx&channel=2&stream=0.sdp" -rtsp_transport tcp -y video.jpg After running, it waits for about 10 seconds and then i get: [rtsp @ 026fd840] UDP timeout, retrying with TCP After another long wait (2 minutes or so), i get: [rtsp @ 028dd840] Could not find codec parameters for stream 0 (Video: h264): unspecified size I

问题 Anyone know of an efficient, feature rich and C# .NET supported library for capturing H264 encoded video streamed from an RTSP server? I'm developing a security application that needs to buffer video for a set amount of time (e.g. 30 seconds), and then when prompted (via an external trigger) record for n seconds after; so that what lead to the event and what happened after is captured. So far I've found the LeadTools Multimedia SDK (which can buffer real time streams with pause/ play/fast

问题 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.

问题 I have an IP camera that is located in a different country ( with a different time zone ) and that has it's own date-time values applied, ( for example:~2012-04-16 11:30:00 ) then the one my PC is located at. ( so my PC's time for example is ~2012-14-16 06:10:00 ) My purpose: When streaming, i need to get this date-time value that is set in camera ("11:30:00") ( I'm not interested in a current local time of my PC ). Is there any way to calculate camera's date-time value from RTP's timestamp ?

问题 I have IP camera and I don't know it's full correct url address to RTSP stream. There is port only in RTSP settings but 192.168.1.132:554 is not enough as I understood. VLC says that rtsp stream is not found. How can I figure out correct url address? 回答1: How can I figure out correct url address? Ask hardware vendor for documentation on this (the best solution) As most cameras have a built-in web server and web client software to interact with the camera. Chances are that web client itself

问题 I'm looking for a method to send video and audio to the rtsp/rtmp server. It should be compatible with notebook webcams and USB webcams. I would like to do it in C#. I found some library called rtmpclient, but it looks it can't send a message to the server. I found also a framework to support webcams that gives a posibility to do an action for every captured frame. But I can't find any similar solution to send a voice with the image. How can I send the video and audio to the server? 回答1:

问题 I'm looking to write a voip application, I know JMF has RTP code but it's old and 32bit only. Is there a robust library that does RTP/RTSP that can be used with java? Thanks 回答1: no way JMF - its 10 years out of date list java RTP RTSP packages: RTSPClientLib.tar.gz on code.google http://github.com/brunodecarvalho/efflux i used the efflux on a java project and it was worth the time learning his packages. The combined netty/efflux is very robust on the variety of RFC's involved in networking
