Can't set dimensions for tap record

[LocNgoXuan23]

Hi @rjhowell44
I encountered a bug when i try to set dimensions (640x360) for tap recording. The output video's dimention actual still same with original dimensions of rtsp stream (1920x1080). How can i fix it. below is my code to create a component:

    def create_source_component(self, component):
        retval = dsl_source_rtsp_new(
            component.source_name,               # source name     
            uri = component.source_uri,          # using hikvision URI defined above   
            protocol = DSL_RTP_ALL,    # use RTP ALL protocol
            skip_frames = 0,           # decode every frame
            drop_frame_interval = 0,   # decode every frame
            latency = 1000,              # 100 ms of jitter buffer
            timeout = 10                # 2 second new buffer timeout 
        )
        if (retval != DSL_RETURN_SUCCESS):    
            logger.error(f'[PGIE - ERROR] DSL Source RTSP New: {dsl_return_value_to_string(retval)}')
            return retval

        if DS_RTSP_STATE_CHANGE_LISTENER:
            # Add the RTSP state-change listener calback to our RTSP Source
            retval = dsl_source_rtsp_state_change_listener_add(component.source_name, self.rtsp_state_change_listener, None)
            if retval != DSL_RETURN_SUCCESS:    
                logger.error(f'[PGIE - ERROR] DSL Source RTSP State Change Listener Add: {dsl_return_value_to_string(retval)}')
                return retval
        
        # add video buffer out format
        retval = dsl_source_video_buffer_out_format_set(component.source_name, DSL_VIDEO_FORMAT_RGBA)
        if retval != DSL_RETURN_SUCCESS:
            logger.error(f'[PGIE - ERROR] DSL Source Video Buffer Out Format Set: {dsl_return_value_to_string(retval)}')
            return retval

            return retval
        
        # set video buffer out fps
        retval = dsl_source_video_buffer_out_frame_rate_set(component.source_name, 12, 1)
