sorry, i am lost. i has update information
Please refer to the sample codes deepstream-image-meta-test. The image is generated in pgie_src_pad_buffer_probe() and saved as image file in osd_sink_pad_buffer_probe().
i had refer to deepstream-image-meta-test but no image saved, this is my gstnvmsgconv.c (23.2 KB) save image code from line 478 to 512
This is a plugin, you just implemented reading image data from the user meta part. Where did you generate mage and put the image data into user meta?
Please refer to the sample codes deepstream-image-meta-test. The image is generated in pgie_src_pad_buffer_probe() and saved as image file in osd_sink_pad_buffer_probe().

i has read funcion pgie_src_pad_buffer_probe() but i don’t now how to appy it to
gst_nvmsgconv_transform_ip(), can you help me
You can implement your own specific app, to generate image user meta in pgie_src_pad_buffer_probe() with nvinfer plugin and use your customized nvmsgconv plugin to handle the image user meta.
please suggest to me how to work with pgie_src_pad_buffer_probe() in nvinfer plugin
The better way is to use pgie_src_pad_buffer_probe() in application with nvinfer src pad.
deepstream-image-meta-test is already the sample.
so difficult with pgie_src_pad_buffer_probe() in deepstream-test5-app-main.c and gstnvmsgconv.c, So different way i can get image at gstdsexample.cpp, are you think sgtnvmsgconv.c can get image like gstdsexample

can you give me an example code for save image in deepstream-test5-app flow your way, thanks so much
@Fiona.Chen @DaneLLL, please help me
You may refer to Encoding jpeg image after OSD causes segfault
deepstream-test5 is a dynamic pipeline app, it is very hard to insert image saving into deepstream-test5 because there is limitation with nvds_obj_enc_create_context() interface.

if get image at OSD i think so difficult to get image path for custom payload to json message broker
It is a sample. You need to find the correct place to put pgie_src_pad_buffer_probe() according to your actual pipeline.

how about Gstdsexample can apply to Gstnvmsgconv for save image. In Gstdsexample i had save image work well.
Can i use Gstdsexample in Gstnvmsgconv like a lib ?
The dsexample can be a sample for you to modify gstnvmsgconv
