This is a fairly dumb copy of the assembly for 8-bit samples but it works and produces identical output to the C version. The options have been tested on an Athlon64 and a Core2Quad. Athlon64: 1810385 decicycles in C, 32726 runs, 42 skips 1080744 decicycles in mmx, 32744 runs, 24 skips, 1.7x faster 818315 decicycles in sse2, 32735 runs, 33 skips, 2.2x faster Core2Quad: 924025 decicycles in C, 32750 runs, 18 skips 623995 decicycles in mmx, 32767 runs, 1 skips, 1.5x faster 406223 decicycles in sse2, 32764 runs, 4 skips, 2.3x faster 387842 decicycles in ssse3, 32767 runs, 1 skips, 2.4x faster 307726 decicycles in sse4, 32763 runs, 5 skips, 3.0x faster Signed-off-by: NMichael Niedermayer <michaelni@gmx.at>

Since lavfi works natively with AVFrame now, these functions are no longer necessary and can be removed in a future bump. Signed-off-by: NMichael Niedermayer <michaelni@gmx.at>

This is admittedly kind of pointless since usually -f image2pipe can be used for the purpose, but this is more user-friendly. Signed-off-by: NReimar Döffinger <Reimar.Doeffinger@gmx.de>

Otherwise ffmpeg -formats claims that we only support demuxing of that format. To keep compatibility the struct could be duplicated instead, but this seems almost like overkill for such a rare format. Signed-off-by: NReimar Döffinger <Reimar.Doeffinger@gmx.de>

- Make MultiByteToWideChar fail when it encounters invalid encoding. Without this, invalid characters might just be skipped - When MultiByteToWideChar fails, assume the file name is in CP_ACP and open it via normal open function, even when the file will be written - When malloc fails return error instead of crashing Signed-off-by: NReimar Döffinger <Reimar.Doeffinger@gmx.de>

Filter private data is memset to 0 so there is no point in explicitly initing anything to 0.

The named constant needs to be searched for in the same object on which the option is set, i.e. target_obj.

To avoid allocating ridiculous amounts of memory for corrupted files, read the input in chunks limited to filesize or an arbitrary large amount when that is not known (chosen to be 50M).
