wm4 8e08a2ec97 vd_lavc: simplify decode return error checking ... This code checked AVFrame.buf[0] instead of the decode return code to see whether a frame was decoded. This is sort of suspicious; while I think that the lavc API actually guarantees it, it's not intuitive anyway. In addition, the code was unnecessarily roundabout. Replace it with a proper error code check. Remove the other error return (that was, or should have been, redundant before). The no-frame path is now cleanly separated. Add an assert on the frame-returned path; if this fails, lavc violated its own API.		2019-12-15 22:26:39 +01:00
