I find below code inside And I want to know can I extract SEI data from this If not, how can I get the h264 frame data?

def pgie_src_pad_buffer_probe(pad,info,u_data):
got_fps = False
gst_buffer = info.get_buffer()
if not gst_buffer:
print("Unable to get GstBuffer ")
# Retrieve batch metadata from the gst_buffer
# Note that pyds.gst_buffer_get_nvds_batch_meta() expects the
# C address of gst_buffer as input, which is obtained with hash(gst_buffer)
batch_meta = pyds.gst_buffer_get_nvds_batch_meta(hash(gst_buffer))
l_frame = batch_meta.frame_meta_list
data =
