[Libva] Measuring fps and frame dropped with gst-vaapi plugins

[Yuan, Feng]

It's good if it can work for you. This patch just for profiling some test cases in my environment in debug mode. Upstream may consider a better one or maybe gstreamer already had.

Thanks Feng, just curious isn't this patch worth a merge into the upstream repo and start allowing some runtime measurement tool to be turned on?

You can try this patch, there's an definition of FPS_CALCULATION(name) to calculate function framerate.
I normally use it to calculate encode/decode/sink framerates.
For example, if you want check fps of
vaapisink, you can write FPS_CALCULATION (vaapisink) in gst_vaapisink_show_frame
vaapidecode, you can write FPS_CALCULATION (vaapisink) in gst_vaapidecode_step just before gst_pad_push

only vaapisink may drop frame, and if this happened, usually there will be GST_WARNING log output from <GstBaseSink>

Thanks,
Wind

Does anyone know if there is such capability from gstreamer-vaapi?

Thanks,
