Record streams of D435i on Android

Hi,

I use the following code to record streams. However, if I  config.enableRecordToFile("streams.bag"); the code will stuck at mPipeline.start(config).

Without it the app runs smoothly.

Is it because of the wrong folder of "streams.bag"?

Thank you!

RsContext.init(getApplicationContext());
 mRsContext = new RsContext();
 mPipeline = new Pipeline(); 
 
 config.enableStream(StreamType.DEPTH, DEPTH_STREAM_WIDTH, DEPTH_STREAM_HEIGHT);
 config.enableStream(StreamType.COLOR, DEPTH_STREAM_WIDTH, DEPTH_STREAM_HEIGHT);
 config.enableStream(StreamType.INFRARED, 1, DEPTH_STREAM_WIDTH, DEPTH_STREAM_HEIGHT, StreamFormat.Y8, 30);

 config.enableRecordToFile("streams.bag");
 //the app stuck here if enableRecordToFile
 mPipeline.start(config)

    Hi Yixun Liu  May I first confirm if you have defined values in your script for DEPTH_STREAM_HEIGHT and DEPTH_STREAM_WIDTH

     

    Does the problem still occur if you define the width and height as hard-coded values like in the code below?

     

    config.enableStream(StreamType.DEPTH, 640, 480,StreamFormat.Z16);
    config.enableStream(StreamType.COLOR, 640, 480, StreamFormat.BGR8);
    config.enableStream(StreamType.INFRARED, 640, 480,StreamFormat.Y8, 30);

    I do use 640x480 and it does not work.

    I think the reason is the file access. If I use config.enableRecordToFile("a.bag"), the default location is the public share folder and it only supports URI access. So I change the code to String path = contex.getFileDir() + "/" + "a.bag"; config.enableRecordToFile(path) and it works now. The contex.getFileDir() return the private File folder and it supports access by a String path.

    One more question is I notice you ignore the index in config.enableStream(StreamType.INFRARED, 640, 480,StreamFormat.Y8, 30); I want to record the first infrared stream. Is its index 0 or 1?

    Thanks.

    If an index number is not defined for the infrared stream when using only left infrared instead of both left and right then it should default to using the left stream.
