FYI if it helps, when I use GStreamer & pylon together, I use pylon's GrabStrategy_LatestImageOnly and try to set the framerate of the camera faster than what my pipeline needs. That way, the camera is always acquiring and transmitting, and Pylon is only holding the most recent image for retrieval. When the next one comes in, if the previous hasn't been retrieved it's just overwritten in memory. This can kind of give the best of both worlds (ignore the error and run with no errors is actually mutually exclusive :)) - if I'm acquiring at 60fps and running my pipeline at 30fps, then if I come across a bad image, I can log the error and hopefully the next good image comes in before the pipeline actually requests it.

It's interesting that it fails to grab the frame. Have you tried debugging it by adding GST_DEBUG=*:5 in front of the gst-launch-1.0 command and seeing if there's anything interesting there?
Either way, to achieve what want you will need to modify the source file (gstpylonsrc.c) and recompile the plugin.
One option would be to simply replace the line at
gst-pylonsrc/plugins/gstpylonsrc.c
Line 2101 in 2073177
return GST_FLOW_OK;, but I'm not quite sure how other gstreamer plugins will react if they receive an empty buffer.
A better alternative would be to set a label (syntax - name:) earlier in the function (like line 2056) and replace this line with a goto to this label (goto name;) so that it just pulls a new frame instead. You will probably need to add
gst-pylonsrc/plugins/gstpylonsrc.c
Line 2097 in 2073177
Sadly I no longer have access to Basler cameras and I can't really test it myself.

Thanks for the reply.
I modified the code as below. seems like issue is fixed.
if(grabResult.Status == Grabbed) {
//TODO: See if I can avoid memcopy and record directly into the gst buffer map.
// Copy the image into the buffer that will be passed onto the next GStreamer element
*buf = gst_buffer_new_and_alloc(pylonsrc->payloadSize);
gst_buffer_map(*buf, &mapInfo, GST_MAP_WRITE);
orc_memcpy(mapInfo.data, grabResult.pBuffer, mapInfo.size);
gst_buffer_unmap(*buf, &mapInfo);
// Release frame's memory
res = PylonStreamGrabberQueueBuffer( pylonsrc->streamGrabber, grabResult.hBuffer, (void*) bufferIndex );
PYLONC_CHECK_ERROR(pylonsrc, res);
// Set frame offset
GST_BUFFER_OFFSET(*buf) = pylonsrc->frameNumber;
pylonsrc->frameNumber += 1;
GST_BUFFER_OFFSET_END(*buf) = pylonsrc->frameNumber;
} else if ( grabResult.Status == Failed ){
GST_ERROR_OBJECT(pylonsrc, "Error in the image processing loop.");
*buf = gst_buffer_new_and_alloc(pylonsrc->payloadSize);
gst_buffer_map(*buf, &mapInfo, GST_MAP_WRITE);
orc_memcpy(mapInfo.data, grabResult.pBuffer, mapInfo.size);
gst_buffer_unmap(*buf, &mapInfo);
// Release frame's memory
res = PylonStreamGrabberQueueBuffer( pylonsrc->streamGrabber, grabResult.hBuffer, (void*) bufferIndex );
PYLONC_CHECK_ERROR(pylonsrc, res);
// Set frame offset
GST_BUFFER_OFFSET(*buf) = pylonsrc->frameNumber;
GST_BUFFER_OFFSET_END(*buf) = pylonsrc->frameNumber;
}
Actually I could not find the grab strategy currently using in pylonsrc. How can I set the grabbing strategy?
Thanks very much.

Hi all,
Please see the gst pipeline I am using for streaming Basler camera,
GST_DEBUG=pylonsrc:5 gst-launch-1.0 -v pylonsrc height=720 width=1280 fps=25 imageformat=mono8 ! videoconvert ! video/x-raw,format=BGR ! videoconvert ! autovideosink
with this I am able to stream vidoe successfully. But I want to feed the video frames to my application for further processing (using appsink _pylonsrc height=720 width=1280 fps=25 imageformat=mono8 ! videoconvert ! video/x-raw,format=BGR ! appsink max-buffers=5 drop=1 ).But its not working ,it seems like application is not receiving video frames at all. I can see few warning messages in the log. attaching the log below:

I am totally unsure of what is going wrong. I hope you can guide me on this issue that I am facing. I really appreciate your help.

Code
It seems that you just copied the buffer copying code from the above block, at which point it was easier to just get rid of the if block altogether. The thing is, there's probably a reason why Pylon didn't mark the frame as grabbed, and you're probably getting incomplete frame there. That said, if it works for you, it's fine.
Actually I could not find the grab strategy currently using in pylonsrc. How can I set the grabbing strategy?
From what I can see in the docs GrabStrategy is a setting for the C++ API, while this plugin implements the C API. My guess the analogue would be to switch to trigger mode (continuous=false) as it would explicitly request frames from the camera as opposed to copying the current frame in the camera's buffer.
Log
There doesn't seem to be anything wrong in the log. Is this log from a normal run?
Also a suggestion for the future, put all code and logs inbetween triple grave accents (```).
I.e.
```
something
/GstPipeline:pipeline0/GstAutoVideoSink:autovideosink0.GstGhostPad:sink: caps = video/x-raw, width=(int)1280, height=(int)720, framerate=(fraction)0/1, format=(string)YV12
something
```
becomes
something
/GstPipeline:pipeline0/GstAutoVideoSink:autovideosink0.GstGhostPad:sink: caps = video/x-raw, width=(int)1280, height=(int)720, framerate=(fraction)0/1, format=(string)YV12
something
This will make things slightly more readable as it doesn't wrap the lines.

Hi zingmars,
code
In else block I have omitted the line
pylonsrc->frameNumber += 1;
Log
What you mean by normal run? This log I generated by running the gst-launch-1.0 command.
I have to feed gstreamer pipeline (as below) to my application, which is not working.
pylonsrc height=720 width=1280 fps=25 imageformat=mono8 ! videoconvert ! video/x-raw,format=BGR ! appsink max-buffers=5 drop=1
Please let me know if you need anything else from me.

There doesn't seem to be anything that indicates an error in that log. In fact, the command you used for that log sent all output to autovideosink (which as I understand works for you) and not appskink. It's also a bit hard to tell what's going on with your appsink without knowing how you're pulling data and what's happening (is no data being buffered? can you even get GstSample out of it?). Tbf even then I'm not sure if I can help much with appsink, as we used this plugin to write to shared memory instead.

Does this mean that pylonsrc plugin has limitations to use with appsink?

No, It just means it was never tested with it so I don't really know what the issue could be.

I've merged pylonsrc into gst-plugins-vision, and have been making some modifications including more comprehensive pixel format support, GStreamer caps negotiation instead of manually setting imageformat, removed the mempcy by wrapping buffers, but I have been seeing this same error reported here.
As best I can tell, the Grabbed result indicates the entire frame was received without errors. If there's any corruption in the image, the result will be Failed, even if most of the image was copied successfully. I can make this problem worse by reducing the packet size on my network adapter.
I'm thinking the best way to handle this is to have a property that will continue grabbing frames even if one is corrupted, and maybe another property that determines whether to pass or drop the corrupted frame.
I created a new issue on gst-plugins-vision for anyone who wants to give input.
