<br>
I am trying to encode the file read by opencv VideoCapture into webm.<br>
After searching the official document of ffmpeg, github, and stackoverflow, I am still far away from my target.<br>
<br>
Can somebody tell me, how to use libvpx, ffmpeg to connect with opencv?<br></blockquote>You'll need to first convert cv::Mat to AVFrame, some code like <a href="http://stackoverflow.com/questions/35907094/converting-cvmat-image-from-bgr-to-yuv-using-ffmpeg">http://stackoverflow.com/questions/35907094/converting-cvmat-image-from-bgr-to-yuv-using-ffmpeg</a><div>Then encode the frames using codec libvpx and mux using format webm (take a look at <a href="https://www.ffmpeg.org/doxygen/3.2/muxing_8c-example.html">https://www.ffmpeg.org/doxygen/3.2/muxing_8c-example.html</a> which is kind of old though.)</div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
