Is it possible to take a screenshot/screencapture using opencv on a mac?

Open spectacularcrackers opened this issue 3 years ago • 14 comments

I would like to take a screenshot of my mac every second using opencv. Is this possible? If so, is there an example that I could reference?

I see the wiki document for windows (https://github.com/bytedeco/javacv/wiki/Screen-Capture-on-Windows), but I am not sure how to implement it for Mac.

According to the docs at https://trac.ffmpeg.org/wiki/Capture/Desktop something like this should work:

  FrameGrabber grabber = new FFmpegFrameGrabber("1");
  grabber.setFormat("avfoundation");
  grabber.setFrameRate(30);
  grabber.start();

I tried using that. However, I keep getting an av_find_input_format() error Could not find input format "avfoundation". Any ideas on how to resolve this?

When I run ffmpeg -f avfoundation -framerate 30 -i "0" -target pal-vcd ./test.mpg in terminal, it records video and saves it to my computer. ffmpeg -s 640x480 -f avfoundation -i "1:0" screenRecording.mpg' saves a screen recording. However, when I try to do the same in a java application, the av_find_input_format() error` arises. The same error happens when I try to capture either the webcam or the screen.

I am using the following dependencies:

    implementation("org.bytedeco:ffmpeg:5.0-1.5.7")
    implementation("org.bytedeco:javacv:1.5.7")
    implementation("org.bytedeco:javacv-platform:1.5.7")

Here is the full error statement:

Exception in thread "main" org.bytedeco.javacv.FFmpegFrameGrabber$Exception: av_find_input_format() error: Could not find input format "avfoundation". (For more details, make sure FFmpegLogCallback.set() has been called.)
	at org.bytedeco.javacv.FFmpegFrameGrabber.startUnsafe(FFmpegFrameGrabber.java:881)
	at org.bytedeco.javacv.FFmpegFrameGrabber.start(FFmpegFrameGrabber.java:849)
	at org.bytedeco.javacv.FFmpegFrameGrabber.start(FFmpegFrameGrabber.java:844)

I tried calling FFmpegLogCallback.set() before FrameGrabber grabber = new FFmpegFrameGrabber("1");, but nothing was in the console

I was able to record from the webcam using OpenCVFrameGrabber rather than FFmpegFrameGrabber. However, I could not record the screen using OpenCVFrameGrabber.

Could you check what you get after setting the "org.bytedeco.javacpp.logger.debug" system property to "true"?

saudet avatar Feb 18 '22 23:02 saudet

I do not see the path org.bytedeco.javacpp.logger.debug. However, I do see the debug variable in org.bytedeco.javacpp.tools.Logger.java. Is this what you are referring to? If so, how do I edit the file? I am using the gradle dependency, and the external libraries are all read-only

spectacularcrackers avatar Feb 18 '22 23:02 spectacularcrackers

It's a "system property", you can set it however your want: https://docs.oracle.com/javase/tutorial/essential/environment/sysprop.html

saudet avatar Feb 18 '22 23:02 saudet

Typically, calling something like System.setProperty("org.bytedeco.javacpp.logger.debug", "true") works.

Got it, thanks.

Here is what it gives

I see, FFmpegFrameGrabber.tryLoad() isn't getting called. I mistakenly commented that out with the upgrade to FFmpeg 5.0, but it's still needed. I've fixed this in commit https://github.com/bytedeco/javacv/commit/fef1d8ee8778dca195bfca35bdf81e9031d2ed12, but we can easily work around that just by calling it explicitly manually.

It works now! Thank you @saudet!

It the default pixel format (bgr24) gave an error. [avfoundation @ 0x119fae530] Selected pixel format (bgr24) is not supported by the input device.

I used one of the suggested supported pixel formats grabber.setPixelFormat(avutil.AV_PIX_FMT_0RGB);, and it worked perfectly.

@saudet do you know of a more efficient way of saving the captured frames? I am currently capturing the screen frames, displaying them on a CanvasFrame and recording from the frame. Do you have an example of how to have the program capture the screen without using a CanvasFrame?

I am trying to use a while loop to continuously capture the frames. However, only one frame gets captured and the recording stops. Any ideas on what I am doing wrong?

        Frame frame;
        while((frame = grabber.grab()) != null){
            recorder.record(frame);
        }
        recorder.stop();
        grabber.stop();

I am getting the following warnings but could not figure out how to resolve them: [AVFoundation indev @ 0x12de64c00] Configuration of video device failed, falling back to default. [avfoundation @ 0x12de64980] Stream #0: not enough frames to estimate rate; consider increasing probesize [aac @ 0x103506660] 1 frames left in the queue on closing

You can stop using CanvasFrame entirely, that's just to display frames. We don't need it to record them.

I don't know, but according to a quick search, it just sounds like a permission problem with your system, for example, see https://github.com/kapoorlakshya/screen-recorder/issues/88#issuecomment-629139032.

I also saw that thread and made sure the permissions were correctly set. The screen gets recorded for one second and the one-two frame clip gets saved. However it then terminates.
