Hi,
</div><div><br></div><div><span class="Apple-tab-span" style="white-space:pre"> </span>Yes, i am sure the androidmedia plugin is working in my testing,</div><div><br></div><div><span class="Apple-tab-span" style="white-space:pre"> </span>but i make a mistake, i am testing again in 1080P case, the CS(NV12 -> RGBx) operation</div><div><br></div><div><span class="Apple-tab-span" style="white-space:pre"> </span>costs about 70ms average time per frame …. it is too much, i use the ffmpegcolorspace plugin to do that, it's the limit of performance in my case :( </div><div><br></div><div><span class="Apple-tab-span" style="white-space:pre"> </span>is there acceleration API about for CS operation in android ? or how to use the YUV format bitmap to display ?</div><div><br></div><div><span class="Apple-tab-span" style="white-space:pre"> </span>i think about this function is a standard module in HW/chip.</div>
<div><div><br></div><div>Thanks,</div><div><br></div><div>- Jojo</div><div><br></div></div>
