The properties of the CDCI Descriptor are insufficient to specify the pixel format for uncompressed picture data. SMPTE 377-1 and RP224v10 have defined a set of picture coding labels to indicate what formatting was used. This patch uses 2 labels to detect UYVY422 or YUYV422 pixel formats. It defaults to UYVY422 for 8-bit 4:2:2 pictures to support files that were created before the coding labels were introduced ~2008 The codec pix_fmt default was changed from 0 (PIX_FMT_YUV420P) to -1 (PIX_FMT_NONE) Reviewed-by: Baptiste Coudurier <baptiste.coudurier@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
