Bayer RG 8 supported?

[zingmars]

Could you please prepend your pipeline with GST_DEBUG=pylonsrc:5, pipe all output to a file, and upload the file here? Also, what version of the Pylon API are you using?

I wonder if the "Bayer RG 8" format listed in the PylonViewerApp is somehow different from "bayer8" here?

It shouldn't be (though it is possible that they changed the pixel format strings, it's been a while). PylonViewerApp is (or used to be) a 1:1 GUI implementation of the API. Bayer was a weird one though, because it would default to Bayer8 BG by default, and the way to change this in the API (at least for our cameras) was by using the Reverse X and Reverse Y functionality. To do this with this plugin for RG you would need to set the flipx and flipy settings to true, i.e.
GST_DEBUG=pylonsrc:5 gst-launch-1.0 pylonsrc imageformat=bayer8 flipx=true flipy=true ! bayer2rgb ! videoconvert ! xvimagesink

@zingmars this is the output of your suggested pipeline:

I am using "pylon 5.0.12 Camera Software Suite Linux x86 (64 bit)".

[zingmars]

Weird. I'll look into it, but I can't promise much since I don't have access to Basler cameras at the moment.

[petergerten]

@zingmars How would I go about to check the supported formats of my camera? PylonViewerApp only gives me "human readable" versions of it.

[zingmars]

The human readable versions correspond with API's pixel format enum (C++/namespace_basler___usb_camera_params.html#a27cff072eee1c5a313f4169e488da874 in the documentation that came with pylon) -

Sadly the plugin doesn't offer a way to list all of the formats available. To do this, you would probably make your own tester. If you have some programming background, the C++/sample_code.html in API docs has examples for a simple camera grab program, You could repurpose it to test all of the pixel formats with something like this (this is a rough adaption from the code samples, I haven't actually tested whether it works or not) -

bool getFormats(Camera_t& camera)
{
    GenApi::NodeList_t Entries;
    camera.PixelFormat.GetEntries(Entries);
    for (size_t i = 0; i < Entries.size(); i++)
    {
        GenApi::INode *pNode = Entries[i];
        if (IsAvailable(pNode->GetAccessMode()))
        {
            GenApi::IEnumEntry *pEnum = dynamic_cast<GenApi::IEnumEntry *>(pNode);
            std::cout << pEnum->ToString();
        }
    }
}

Is there any solution available for Bayer RG 8. I am facing the same problem with acA4112 -8gc camera. I tried flipx=true and flipy= true but still facing the same.
with Bayer GR 8 format, I was able to stream video with flipy=true option.

Kindly help

@zingmars
This plugin is currently not supporting any Bayer format due to incorrect choosing of a filter.

Used it several months, with RGB imageformat until I get the old camera which support Bayer only.
Successfully patched your plugin, ready to make a PR. Should I fork your repo or I can create new branch in this one?

Fork and make a PR.

@petergerten if this is still relevant, could you try it again with the latest version?
