在Android设备上捕获RTSP流

Question

I want to capture a RTSP video stream from an ip camera with my Nexus S. To watch the stream with a VideoView and the mediaplayer is no problem.

I tried to save it like this:

                URL url = new URL("rtsp://192.168.4.222:554/ipcam.sdp");
                URLConnection ucon = url.openConnection();
                ucon.connect();
                InputStream is = ucon.getInputStream();
                fos = new FileOutputStream(VideoFile);
                bis = new BufferedInputStream(is);
                isRecording = true;
                baf = new ByteArrayBuffer(50);
                int current = 0;
                FileOutputStream fos = new FileOutputStream(VideoFile);
                while (((current = bis.read()) != -1) & isRecording) {
                        baf.append((byte) current);
                        fos.write(baf.toByteArray());
                        baf.clear();
                }                    
                fos.close();

I get a MalformedURLException, because android doesn't support rtsp:// urls.

Has somebody an idea how to solve this problem?

Answer 1

根据http://developer.android.com/reference/java/net/URLConnection.html.RTSP还不是支持的协议

Answer 2

You can use ffmpeg libraries through JNI/NDK to capture an rtsp stream. It's not very easy, but it does work.
