Android: record video with FFmpegFrameRecorder in onPreviewFrame not working
I have to take video in my application and I use FFmpegFrameRecorder to do that. The video is show correctly in some devices but not on GalaxyS3. I record the video in onPreviewFrame callback function. Like this:
public void onPreviewFrame(byte[] data, Camera camera) {
...
synchronized (mVideoRecordLock) {
if (recording && lplImage != null)
{
try {
ByteBuffer buffer;
buffer = lplImage.getByteBuffer();
if(buffer.remaining() < lastSavedframe.getFrameBytesData().length){
ByteBuffer temp = ByteBuffer.allocate(lastSavedframe.getFrameBytesData().length);
buffer = temp;
}
buffer.put(lastSavedframe.getFrameBytesData());
videoRecorder.setTimestamp(lastSavedframe.getTimeStamp());
videoRecorder.record(lplImage);
}
lastSavedframe = new SavedFrames(data,frameTimeStamp);
}
}
lplImage: IplImage Type lastSavedframe : save frame data in a byte[]. The class file:
public class SavedFrames implements Parcelable{
byte[] frameBytesData = null;
long timeStamp = 0L;
String cachePath = null;
int frameSize = 0;
...
}
My problem is: with S3, buffer.remaining() < lastSavedframe.getFrameBytesData().length, the video is not recorded correctly, cause I make a preview activity, and the video is green.
I've been struggling with this problem.. Any idea will be appreciated!
Test with galaxy S3, android os 4.0.4. The opencv-core.jar's version is 1.5 (I use a library in my application and the library use opencv-core 1.5)
Thanks!
since this is javacv-specific, i fear you're barking up the wrong tree here ..
