If video output and VO don't support the same format, a conversion filter needs to be insert. Since a VO can support multiple formats, and the filter chain also can deal with multiple formats, you basically have to pick from a huge matrix of possible conversions. The old MPlayer code had a quite naive algorithm: it first checked whether any conversion from the list of preferred conversions matched, and if not, it was falling back on checking a hardcoded list of output formats (more or less sorted by quality). This had some unintended side- effects, like not using obvious "replacement" formats, selecting the wrong colorspace, selecting a bit depth that is too high or too low, and more. Use avcodec_find_best_pix_fmt_of_list() provided by FFmpeg instead. This function was made for this purpose, and should select the "best" format. Libav provides a similar function, but with a different name - there is a function with the same name in FFmpeg, but it has different semantics (I'm not sure if Libav or FFmpeg fucked up here). This also removes handling of VFCAP_CSP_SUPPORTED vs. VFCAP_CSP_SUPPORTED_BY_HW, which has no meaning anymore, except possibly for filter chains with multiple scale filters. Fixes #1494. |
