<div dir="ltr">I can't remember exactly, but there is an option in the encoder structure to instruct the VPU encoder to generate an I-Frame. Just make sure that you clear the flag after the I-Frame is generated. Of course, the structure item name may vary depending on which VPU you are using. Your encoder element probably already controls when to generate an I-Frame. When I worked with a Freescale VPU we had to determine the I-Frame rate ourselves, the encoder didn't count the frames. </div><div class="gmail_extra"> <div class="gmail_quote">On Thu, Sep 26, 2013 at 8:25 PM, Javier Jardón <<a href="mailto:jjardon@gnome.org" target="_blank">jjardon@gnome.org</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hi, I need to generate a keyframe in a specific time. Looking to the code of vpuenc [1], seems that it doesnt handle events from downstream (GST_EVENT_CUSTOM_DOWNSTREAM) to check if the event request a keyframe: gst_video_event_is_force_key_unit (event) (and no, it doesnt derive from the GstVideoEncoder baseclass class) This can be easily implementable but my question is: Any of you know the specific option I have to pass to the vpu to generate a keyframe? Or any other way? I read about encparam->forceIPicture , but Im not sure Im looking in the correct direction Could someone help me with this?
