Hi, 2013/1/10 Tay, Boon Wooi <[email protected]>:
> Does anyone know if there is such capability from gstreamer-vaapi? 1. Dropped frames. Programmatically, you usually get a QoS message (GST_MESSAGE_QOS) at the application level, where you can call gst_message_parse_qos_stats() to get `processed' and `dropped' fields. 2. FPS. There is no reliable tool for that. On GenX, with X11, you will render at most at 60 fps by default. So running with sync=false will cap your results to 60 fps. The other thing is that you would need to also call vaSyncSurface() / gst_vaapi_surface_sync() before updating your measurement metrics. Otherwise, that won't be accurate, VA processing is async.
