Bitrate fluctuation is normal in case of I-frame. I don't know if you can do much about it apart from using rate control. <div>Do you use any rate control?</div><div>Instead of having periodical intra-frame refresh you could have cyclic intra macroblock refresh. It means you do not refresh the whole frame at once but you have some macroblocks forced to be encoded as intra in every frame.</div> <div>Thus the whole frame is intra-refreshed after some period of time.<br><br><div class="gmail_quote">2011/12/3 Umakant Goyal <span dir="ltr"><<a href="mailto:umakantgoyal1@gmail.com">umakantgoyal1@gmail.com</a>></span><br> <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">Hi Ashwini, I think you misunderstood me. Here i am not talking about picture size.I need to reduce the number of bits that is being produced by encoder to generate I-Frame. Please suggest how to reduce the number of bits for per I-Frame without loosing the quality much.<br> <br>Thanks<div><div></div><div class="h5"><br><br><div class="gmail_quote">On Fri, Dec 2, 2011 at 4:43 PM, Ashwini Sharma <span dir="ltr"><<a href="mailto:ak.ashwini@gmail.com" target="_blank">ak.ashwini@gmail.com</a>></span> wrote:<br> <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> Hi,<div><br></div><div>I think you can use videoscale to do the job.</div><div><br></div><div>--Ashwini<br><br><div class="gmail_quote"><div>On Mon, Nov 28, 2011 at 10:58 PM, Umakant Goyal <span dir="ltr"><<a href="mailto:umakantgoyal1@gmail.com" target="_blank">umakantgoyal1@gmail.com</a>></span> wrote:<br> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div>Hi, What all settings of ffenc_h263 will help me to control/reduce the size of I-Frame?<br><br>Thanks in Advance <br> <br></div>_______________________________________________<br> gstreamer-devel mailing list<br> <a href="mailto:gstreamer-devel@lists.freedesktop.org" target="_blank">gstreamer-devel@lists.freedesktop.org</a><br> <a href="http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel" target="_blank">http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel</a><br> <br></blockquote></div><br></div> <br>_______________________________________________<br> gstreamer-devel mailing list<br> <a href="mailto:gstreamer-devel@lists.freedesktop.org" target="_blank">gstreamer-devel@lists.freedesktop.org</a><br> <a href="http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel" target="_blank">http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel</a><br> <br></blockquote></div><br> </div></div><br>_______________________________________________<br> gstreamer-devel mailing list<br> <a href="mailto:gstreamer-devel@lists.freedesktop.org">gstreamer-devel@lists.freedesktop.org</a><br> <a href="http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel" target="_blank">http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel</a><br> <br></blockquote></div><br><br clear="all"><div><br></div>-- <br>Your Sincerely<br>Michal Joachimiak<br> </div>
