It's 2020, and the problem is still there. I had to rebuild x264 with --bit-depth=8, then rebuild ffmpeg, and blink and sip-message started to work. I don't get the segmentation fault, different bit depth still breaks autodetection. https://lists.ag-projects.com/pipermail/blink/2016-February/003495.html -- Yours sincerely, Vladimir Nikishkin
