#658(undetermined:new): auto-select yuv420p for RGB inputs with libx264

#658: auto-select yuv420p for RGB inputs with libx264 -------------------------------------+------------------------------------- Reporter: llogan | Owner: Type: | Status: new enhancement | Component: Priority: wish | undetermined Version: git- | Keywords: master | Blocking: Blocked By: | Analyzed by developer: 0 Reproduced by developer: 0 | -------------------------------------+------------------------------------- I've noticed an increasing number of users wondering why their outputs are not playing normally in some video players, and/or why some profiles won't work ("main profile doesn't support 4:4:4" for example). The general answer is to tell them to use "-pix_fmt yuv420p". x264 technically supports RGB, but I think the vast majority of users will want YUV, although they may not know it. We closed a few similar reports as invalid (#585 and #601) because the current behavior isn't wrong, but it is inconsistent, but now that I see more questions about this I think the default behavior should be changed.
