<div dir="ltr"><div>you are absolutely in the right path. you just have to figure how to implement a function that copies/translate the pixels from you QT data-structure into the buffer that in the example is being filled with self-generated data. <br>It may be as easy as to copy each r,g,b byte or depending on your input/output formats, it may require some manipulation to properly decode/encode the pixels in the right formats (bit lengths, channel order, etc) <br>I went through that path a couple of months ago, in my case I was writing a video-recorder chrome-extension and had to copy the pixels from the chrome-video stream into the ffmpeg AVFrame. I used the same example that you as reference for that. <br><br></div><div>other tricky part you will have to solve (once you will be able to copy frames) will be the timing of each frame. but that is another history. <br></div></div><div class="gmail_extra"><br clear="all"><div><div class="gmail_signature"><div dir="ltr">Cesar Pachón<br>-------------------------------------------------------------<br><a href="http://www.cesarpachon.com" target="_blank">www.cesarpachon.com</a>, just a digital hermit<br><br></div></div></div>
