Just like the fourcc line, there can be multiple out lines or multiple comma-separated output formats on the same line. The output formats should be listed in order of preference. + The outfmt values can be followed by one or more flags, like flip, noflip, -static, querty.

Describe these in detail: + +"flip": + If this flag is set for a given format, then o_bih->biHeight will NOT be + set to -bih->biHeight, ie image will be decoded upside-down. + Used only by vfw and vfwex codecs. + +"noflip": + This flag is ignored (no effect) without "flip" being set! + If this flag is set, it means the codec doesn't decode upside-down, + altought it's told to do so. + +"yuvhack": + This flag is required for the old win32 ms-mpeg4 vfw codecs, including + MP42 and DIV3 (divx 3.11). These DLLs actually support YUV formats, + but the query/begin functions are buggy and don't accept YUV fourccs + (the decode func. accepts it and works well!) + If this flag is set, then o_bih->biCompression will be set to 0 for + the initialization for the YUV modes. Used only by vfw/vfwex codecs. + +"query": + This flag is used to control VDCTRL_QUERY_FORMAT for vfw/vfewx codecs. + If thsi flag is set, the control() will query the codec for the csp + support, otherwise it will assume constant csp table. Required for + some DLLs (like huffyuv, CRAM). + +"static", + This flag forces STATIC (instead of TEMP) buffer allocation for the codec. + Used for some very old DLLs like Indeo 3 and for some xanim codecs like + cinepak.
