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"?

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

It's a "system property", you can set it however your want:

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

Got it, thanks.

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 fef1d8e, 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

@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?

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

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

I don't know, but according to a quick search, it just sounds like a permission problem with your system, for example, see
kapoorlakshya/screen-recorder#88 (comment).

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.

@spectacularcrackers There's another issue in the case of avfoundation that was fixed in commit 8d75c0a, see issue #1784.
Please give it a try with the snapshots: http://bytedeco.org/builds/
