    88Running on Windows 10 with an Intel GPU (Intel UHD Graphics 620, but I suspect this problem isn't related to the exact hardware version - it also reproduced on another machine). The RTSP stream comes from a camera. It looks like it has a pixel format of 720x576, pix_fmt: yuvj420p. If there is a way to capture this stream such that someone else can reproduce the error, please let me know. I suspect the reproduction of this problem requires a genuine RTSP server.
