Sandybridge: 47 cycles Having a loop counter is a 7 cycle gain. Unrolling is another 7 cycle gain. Working in reverse scan is another 6 cycles. Signed-off-by:

If building libav with -MD in the cflags (for making the MSVC compiler generate code for using a dynamically linked libc), the system headers that declare strtod, snprintf and vsnprintf declare the functions as imported from a DLL. To hook up wrappers of our own for these functions, the function names are defined to avpriv_*, so that the calling code within libav calls the wrappers instead. Since these functions are declared to be imported from DLLs, the calling code expects to load them from DLL import function pointers (creating references to _imp__avpriv_strtod instead of directly to avpriv_strtod). If the libav libraries are not built as DLLs, no such function pointers (as the calling code expects) are created. The linker can fix this up automatically in some cases (producing warnings LNK4217 and LNK4049), if the object files are already included. By telling the linker to try to include those symbols (without the _imp prefix as the calling code ends up using), we get the object files included, so that the linker can do the automatic fixup. This is done via config.h, so that all (or at least most) of the object files in our libraries force including the compat files, to make sure they are included regardless of what files from our static libraries actually are included.

Hack partially based on a commit by Michael Niedermayer <michaelni@gmx.at> Should fix (or work around) bug 458.

Integrate the code in the packet reading function, instead of inserting sleeps in many places. This is simpler to follow and should work better.

97c -> 49c Some codecs could benefit from more unrolling, but AAC doesn't.

-t 0.5 is 12.5 frames at 25 fps, which may round to either 12 or 13 on different platforms.

It has been deprecated some time ago, but was forgotten during the last bump.

This avoids cases where configure tries to weakly enable an item which actually is disabled, ending up still enabling dependencies of the item which itself is only enabled weakly. More concretely, the h264 decoder suggests error resilience, which is then enabled weakly (unless manually disabled). Previously, dsputil, which is a dependency of error resilience, was enabled even if error resilience wasn't enabled in the end. Signed-off-by:

The variable name 'var' is commonly used to iterate through arguments in other functions. When the pushvar function internally uses the variable 'var', it makes pushing/popping the variable 'var' not work as intended. Signed-off-by:

The function does not do any rounding, so there is no point in keeping it in a round template file.

The function is only instantiated once, so there is no point in keeping it in a template file.
