Anton Khirnov	9177970bca	lavc/bitstream: templatize for BE/LE Allows using both BE and LE bitstream readers in the same file.	2 years ago
Alexandra Hájková	8fe551eca0	lavc: add standalone cached bitstream reader The cached bitstream reader was originally written by Alexandra Hájková for Libav, with significant input from Kostya Shishkov and Luca Barbato. It was then committed to FFmpeg in `ca079b0954`, by merging it with the implementation of the current bitstream reader. This merge makes the code of get_bits.h significantly harder to read, since it now contains two different bitstream readers interleaved with #ifdefs. Additionally, the code was committed without proper authorship attribution. This commit re-adds the cached bitstream reader as a standalone header, as it was originally developed. It will be made useful in following commits. Integration by Anton Khirnov. Signed-off-by: Anton Khirnov <anton@khirnov.net>	2 years ago
Luca Barbato	79f64f7ebc	bitstream: Avoid undefined behavior in bitstream_skip() Do not use skip_remaining() to fully wipe the cache, as this could do a 64-bit shift of a 64-bit variable which is undefined behavior in C. Instead set the related variables to zero directly. Thanks to Uoti for pointing out the problem. CC: libav-stable@libav.org	7 years ago

Alexandra Hájková	dd3d7ddf2a	lavc: add a new bitstream reader to replace get_bits The new bit reader features a simpler API and an implementation without stacks of nested macros. Signed-off-by: Anton Khirnov <anton@khirnov.net>	8 years ago

Diego Pettenò	be449fca79	Convert asm keyword into __asm__. Neither the asm() nor the __asm__() keyword is part of the C99 standard, but while GCC accepts the former in C89 syntax, it is not accepted in C99 unless GNU extensions are turned on (with -fasm). The latter form is accepted in any syntax as an extension (without requiring further command-line options). Sun Studio C99 compiler also does not accept asm() while accepting __asm__(), albeit reporting warnings that it's not valid C99 syntax. Originally committed as revision 15627 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Stefano Sabatini	987903826b	Globally rename the header inclusion guard names. Consistently apply this rule: the guard name is obtained from the filename by stripping the leading "lib", converting '/' and '.' to '_' and uppercasing the resulting name.
