* avcodec: add multi vlc readerPaul B Mahol2023-09-07
| | | | | | Heavily based and inspired by Christophe's cache branches. Co-Authored-by: Christophe Gisquet
* lavc/bitstream: avoid UB in bits_{read,peek}_signed(0)Anton Khirnov2023-01-18
| | | | | | | | | | bits_*_signed(0) will currently invoke an undefined shift by 8 * sizeof(int). Add bits_*_signed_nz() that only works for n>0, analogous to bits_read_nz(). Add an explicit check for n=0 in bits_*_signed(). Found-by: James Almer
* lavc/bitstream: templatize for BE/LEAnton Khirnov2023-01-06
| | | | Allows using both BE and LE bitstream readers in the same file.
* lavc: add standalone cached bitstream readerAlexandra Hájková2023-01-06
| | | | | | | | | | | | | | | | | | | | 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 ca079b09549, 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>

* Convert asm keyword into __asm__.Diego Pettenò2008-10-16
| | | | | | | | | | | | | 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
* Globally rename the header inclusion guard names.Stefano Sabatini2008-08-31
| | | | | | | | | 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. Guard names in the root directory have to be prefixed by "FFMPEG_". Originally committed as revision 15120 to svn://svn.ffmpeg.org/ffmpeg/trunk
