Android :: Video Loop Recording Application (Retrospective)
Sep 9, 2010
Does anyone know of a video loop recording app that would work so as to allow "retrospective " recording - i.e. it records full time but discards after say five minutes, so that by -say -pressing a button, the previous five minutes recording could be retained , reviewed and possibly saved? I know it could be done by recording to a file for a fixed period and then discarding that file and starting a new one, but then it would be random as to the length of the recording that was available on the current file - depending on when the button was pressed. What I need is something that writes data to a fixed length file and pushes the earliest written data off the end - or some other process that simulates that.

I'm running my HTC Legend with the stock "Camcorder" app and the most I can record with is 480p. Since the iPhone 4 has the same MP (5) and can shoot HD, why can't the Legend. Is there an app for such a thing? Any way without rooting, since I still want to keep my warranty till it expires.

Any of you see a lot of banding on the camera app in medium to low lighting. The flash usually prevents banding from appearing in pictures but when recording there is huge amounts of banding. is this normal?

I am looking for video recording example, it suppose to be in api - sample but not available. I am wondering if 1.1 release still missing this feature?
If it does support then in which format and where is the example. Also I am trying to figure out MP3 encoding long ago but still no solution. I have recorded an audio ()which is in AMR by default, how can I convert it in MP3 (any external package I can use?)

Is video recording supported in 1.5? I got it mostly working with the Haykuro 1.5 ADP image - the video file was legally formatted but didn't play properly.
With yesterday's official 1.5 images, it doesn't work at all.
setVideoEncoder() fails,
with the wonderfully informative error message
"setVideoEncoder failed".

I just experienced the video recording on G1 based on the system.img of android1.0. The process just lasts about 3 seconds, then blocks. And the generated file is empty. What's the matter? Doesn't this version support video recording, yet?

I've tried video recording in the background. But had failed.
Under normal circumstances, the recording works properly. However, if HOME key down-> Home screen or Other Activity is running, recording terminates.
In such a situation, I want to record continuously. I want to record whole process!

I was wondering if anyone knows of a tutorial explaining how to capture the video from the camera on an Android device and then display the video in real time on the screen? I have looked up MediaRecorder, MediaPlayer, Videoview but they all seem concerned with recording audio/video to a file or playing audio/video from a file or a URL. I simply want to be able to take the data from what the camera is seeing and display it on the screen.

I read that along with 2.1 Android update, the X10 is also getting an update to be able to record in HD? I was wondering does this mean you will have to get another X10 for it to video record? Or can you just update your phone and it will be able to HD record?

When I add video source and video encoder, it gives error in recoreder.prepare() (prepare failed) while the same code is working only for audio. I am not finding what I am doing wrong.
setContentView(R.layout.camera);
preview=(SurfaceView)findViewById(R.id.surface);
previewHolder=preview.getHolder(); previewHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
recorder = new MediaRecorder();
String url = "/sdcard/dcim/test.3gp";
camera = Camera.open();
Camera.Parameters parameters = camera.getParameters();
parameters.setPreviewSize(352, 288);
parameters.set("orientation", "portrait");
camera.setParameters(parameters);
recorder.setAudioSource(MediaRecorder.AudioSource.MIC); recorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
recorder.setOutputFile(url);
recorder.setVideoFrameRate(15);
recorder.setVideoSize(480, 320);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB); recorder.setVideoEncoder(MediaRecorder.VideoEncoder.H263);
recorder.prepare(); recorder.start(); Thread.sleep(100000);
recorder.stop(); recorder.release();
} catch (Exception e) { e.getMessage(); }

I am trying to develop an app which streams live audio/video. I have the mediarecorder to record both audio, video frames , and it does so. But the thing is it records a chunk of audio and then records a chunk of video frames and then records a chunk of audio frames to the file. How do I determine where my audio frames start and where the video frames start?. Also is there any way to figure out the Video frame length ?. Iam really stuck at this point and any help will be greatly appreciated. This is how I initialize the mediarecorder in my app, Code...

Is the Evo supposed to be auto-focusing when its recording video? If I have just the viewfinder and no recording going on, it auto-focuses whatever I point it at, but when it comes to recording, its not auto-focusing at all. It just stays blurry.

Don't know if anyone knew this but if you download the LED Desire light from the app store, use the app first to leave the LED lights on and go to your video recorder. You can now record video in the dark and have somewhat clarity with the LED lights on. Granted it would probably be a big energy waster, but atleast you know have a choice.

Is there any way to pause the video recording function? I've looked all over the net and can't find an app or a reason why this feature seems to be missing from all Android phones.
This is HD recording and could potentially replace low end video units. Seems like it should be unnecessary to use an external video editor to get a vacation video in one piece.
