Mats Peterson	191ec55c9f	lavc/rawdec: Use 16-byte line alignment for AV_PIX_FMT_MONOWHITE The line alignment for 1 bpp raw AV_PIX_FMT_MONOWHITE video (currently used for AVI) was previously 4 bytes, which generated alignment warning messages, not only for odd-width files.

At the same time, the packet row stride is properly catered for. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago

Mats Peterson	5da1477fa0	lavc/rawdec: Use AV_PIX_FMT_PAL8 for 1-bit raw QuickTime video Match the use of AV_PIX_FMT_PAL8 for 1-bit QuickTime Animation in lavc/qtrle. To reiterate, 1-bit video is not necessary black & white in QuickTime, merely bi-level. The two colors can be any color. The palette, either included in the sample description, or the default Macintosh palette (black & white for 1-bit video) will be set in lavf/qtpalette. See the QuickTime File Format Specification for details. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago

Carl Eugen Hoyos	54bbe3e2a6	Revert "Allow stream-copying grayscale mov files." This reverts commit `691dec6201`. The commit did not fix ticket #3215, it was fixed one commit earlier.

Hendrik Leppkes	8962da9ec3	rawdec: allocate a buffer in the appropriate size in the copy case.
