No element tisvideobufferfilter, tiscolorize, tis_auto_exposure, bayer2rgb

[jdog816]

I'm trying to run a custom script based on tiscamera, using a DFM 22BUC03-ML camera in Ubuntu 18. The script is saving images to a folder, but they are coming out grey and I'm getting these errors:

 Running in verbose mode

I believe this is the relevant portion of the script:

 //Build the pipeline
 const gchar* Pipeline = "v4l2src name=camera "
                      "! video/x-raw-gray,width=640,height=480,framerate=15/1 "
                      "! tisvideobufferfilter name=videofilter "
                      "! videocrop top=0 left=80 right=80 bottom=0 "
                      "! tiscolorize "
                      "! tis_auto_exposure name=exposure " //region-x0=80 region-y0=80 region-x1=400 region-y1=400 "
                      "! bayer2rgb "
                      "! ffmpegcolorspace "
                      "! jpegenc name=jpegencoder quality=" INITIALJPEGQUALITY " "
                      "! appsink name=jpegframe ";

Would it just be a matter of commenting out some of those lines, or editing them with the 1.0 plugin names?

[jdog816]

For example, were "tisvideobufferfilter" and "jpegenc" changed to something new when migrating from 0.1 to 1.0 ?

[jdog816]

Sorry for multiple questions, but I'm getting:

 GStreamer-CRITICAL **: 21:00:37.623: gst_buffer_get_sizes_range: assertion 'GST_IS_BUFFER (buffer)' failed

 GStreamer-CRITICAL **: 21:00:37.790: gst_buffer_map_range: assertion 'GST_IS_BUFFER (buffer)' failed

Any ideas?

In tiscamera 1.0 these elements are no longer available. First of all I suggest to use GStreamer 1.0. I can not provide support for Gstreamer 0.10 anymore Also I suggest to use the current tiscamera 1.0. Your pipeline is that:

const gchar* Pipeline = "tcambin name=camera "
                      "! video/x-raw,format=BGRxwidth=640,height=480,framerate=15/1 "
                      "! videocrop top=0 left=80 right=80 bottom=0 "
                      "! videoconvert "
                      "! jpegenc name=jpegencoder quality="INITIALJPEGQUALITY " "
                      "! appsink name=jpegframe ";

We only need to configure the auto functions ROI by tcambin properties. As soon as I have access to camera and Linux computer, I will have a look.

[TIS-Stefan]

Now I would like to add the properties. In tcam-capture you can set the properties, if the pipeline is in READY state, just before PLAYING. That is new.

// Get tcambin from the pipeline and set it in state READY:
GstElement* source = gst_bin_get_by_name(GST_BIN(pipeline), "camera");
gst_element_set_state(pipeline, GST_STATE_READY);
gst_element_get_state(pipeline, NULL, NULL, 4000000000ll);

// Set the Auto Functions ROI properties now. With error handler.
    tcam_property_provider_set_tcam_boolean(TCAM_PROPERTY_PROVIDER(source), "AutoFunctionsROIEnable", true, &err);
    if (err)
    {
        printf("Error while retrieving AutoFunctionsROIEnable: %s\n", err->message);
        g_error_free(err);
        return 1;
    }

    tcam_property_provider_set_tcam_enumeration(TCAM_PROPERTY_PROVIDER(source), "AutoFunctionsROIPreset", "Custom Rectangle", &err); 
    if (err)
    {
        printf("Error while retrieving AutoFunctionsROIPreset: %s\n", err->message);
        g_error_free(err);
        return 1;
    }

    tcam_property_provider_set_tcam_integer(TCAM_PROPERTY_PROVIDER(source), "AutoFunctionsROILeft", 80, &err); 
    if (err)
    {
        printf("Error while retrieving AutoFunctionsROILeft: %s\n", err->message);
        g_error_free(err);
        return 1;
    }

    tcam_property_provider_set_tcam_integer(TCAM_PROPERTY_PROVIDER(source), "AutoFunctionsROIWidth", 560, &err); 
    if (err)
    {
        printf("Error while retrieving AutoFunctionsROIWidth: %s\n", err->message);
        g_error_free(err);
        return 1;
    }

    tcam_property_provider_set_tcam_integer(TCAM_PROPERTY_PROVIDER(source), "AutoFunctionsROITop", 0, &err); 
    if (err)
    {
        printf("Error while retrieving AutoFunctionsROITop: %s\n", err->message);
        g_error_free(err);
        return 1;
    }

    tcam_property_provider_set_tcam_integer(TCAM_PROPERTY_PROVIDER(source), "AutoFunctionsROIHeight", 400, &err); 
    if (err)
    {
        printf("Error while retrieving AutoFunctionsROIHeight: %s\n", err->message);
        g_error_free(err);
        return 1;
    }

 //Start the pipeline
 gst_element_set_state(pipeline, GST_STATE_PLAYING);
 gst_element_get_state(pipeline, NULL, NULL, 4000000000ll);

   printf("Press enter to stop the stream.\n");
    getchar();

    /* cleanup, reset state */
    gst_element_set_state(pipeline, GST_STATE_NULL);
    gst_element_get_state(pipeline, NULL, NULL, 4000000000ll);

    gst_object_unref(source);

I hope, I got the Auto Functions ROI coordinates correct according to your ROI.

Solved some of the problems by following this document, but getting an error that's not explained here: https://github.com/Xilinx/gstreamer/blob/master/docs/random/porting-to-1.0.txt I opened a separate issue for it, so I'll close this one.
