<p class="MsoNormal"><span style="color:#1F497D">You can try this patch, there’s an definition of FPS_CALCULATION(name) to calculate function framerate.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">I normally use it to calculate encode/decode/sink framerates.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">For example, if you want check fps of
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">vaapisink, you can write FPS_CALCULATION (vaapisink) in gst_vaapisink_show_frame<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">vaapidecode, you can write FPS_CALCULATION (vaapisink) in gst_vaapidecode_step just before gst_pad_push<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">only vaapisink may drop frame, and if this happened, usually there will be GST_WARNING log output from <GstBaseSink><o:p></o:p></span></p>
