support yvyu in avi

[ami_stuff]

attached file decodes correctly with

libavcodec/raw.c:

    { PIX_FMT_UYVY422, MKTAG('c', 'y', 'u', 'v') }, /* CYUV is also Creative YUV */
+    { PIX_FMT_YUYV422, MKTAG('Y', 'V', 'Y', 'U') },
    { PIX_FMT_UYYVYY411, MKTAG('Y', '4', '1', '1') },

libavformat/riff.c:

    { CODEC_ID_RAWVIDEO,     MKTAG('a', 'u', 'v', '2') },
+    { CODEC_ID_RAWVIDEO,     MKTAG('Y', 'V', 'Y', 'U') },
    { CODEC_ID_FRWU,         MKTAG('F', 'R', 'W', 'U') },

but requires swap of uv (-vf swapuv)

[Carl Eugen Hoyos]

Can (vanilla) Windows Media Player decode the sample?

[ami_stuff]

Yes, decodes fine with WMP.

[Carl Eugen Hoyos]

Should be fixed.
