How can I force wireshark to decipher some types of protocols if it doesn't recognize them (RTSP,RTP, RTCP)?

问题 I'm trying to implement RTSP protocol in Java according to http://www.csee.umbc.edu/~pmundur/courses/CMSC691C/lab5-kurose-ross.html example; I have succeed up to successful communication with VLC via RTSP requests and streaming RTP packets; RTP packets with JPEG payload are not recognized by VLC well; that's why I supposed I send malformed RTP. I sniffed them with wireshark and compared them with packets, sniffed from successfull RTSP communication of gstreamer RTSP streamer and VLc. I was

Code: from imutils.video import VideoStream import cv2 # Read rtsp stream rtsp = u"rtsp://admin:admin@10.64.1.31:554/1/h264major" #vs = VideoStream(src=0).start() # for capturing from webcam vs = VideoStream(src=rtsp).start() while True: frame = vs.read() # show the output frame cv2.imshow("Frame", frame) key = cv2.waitKey(1) & 0xFF # if the `q` key was pressed, break from the loop if key == ord("q"): break # do a bit of cleanup cv2.destroyAllWindows() vs.stop() I have faced the same problem when using opencv's VideoCapture [ cap.isOpened() returns False ] The standalone executable works fine

Process RTSP with Node.js for taking an image snapshot

由 时光怂恿深爱的人放手 提交于 2019-12-07 04:16:19
问题 I have a RTSP that I would love to make Node.JS understand. I found a way to do it using Java taking a capture from a webcam but I would love to just use Node.js on this task and get it from a video RTSP'd. My intention is to use setInterval, grab the stream, convert it to base64 and stream it through Socket.IO to a client so they can see it as a <img> tag on their browser. Much of this will be taken from the guy who make it with a webcam but I only have a RTSP available as video-source. So,

UPDATE I found this from GITHUB but dont know How to implement it in my App. Please help me by sample code or related app and suggest me to overcome this. thanks in Advance.

What library is best for a H264 video stream streamed from an RTSP Server?

由 落花浮王杯 提交于 2019-12-07 02:55:33
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 forward/etc functionality), but its libraries and documentation for C# are lacking; with most of the

Decode h264 rtsp with ffmpeg and separated AVCodecContext

问题 I need some help with decodein rtsp stream of video. I get it from AXIS IP-camera. I use ffmpeg library for it. It is neccessary to create AVCodecContext separately, not from AVFormatContext->streams[...]->codec; So i create AVCodec, AVCOdecContext and try to init them. AVCodec *codec=avcodec_find_decoder(codec_id); if(!codec) { qDebug()<<"FFMPEG failed to create codec"<<codec_id; return false; //--> } AVCodecContext *context=avcodec_alloc_context3(codec); if(!context) { qDebug()<<"FFMPEG

I'm trying to extract mpeg4 from an rtp payload , format of the rtsp media (video) is MP4V-ES but I'm not able to extract the mp4 from the payload . when I dump the extract into a raw file and use ffmpeg to convert it into .avi or .mpg its not working. I don't know what I'm missing here. the code is written in java. I want to extract each video frame from the rtp and save that in a file or retransmit it. Thanks Question UPDATED..... Thanks for the inputs, actually I'm able to extract bytes from 000001b6 and sent it to ffmpeg , but it complains about not header information and then I
