Andreas Rheinhardt	51ca74b525	avcodec/dvdec: Avoid stack buffers Instead reuse the destination RL VLC as scratch space. This is possible, because the (implicit) codes here are already ordered from left-to-right in the tree and because the codelengths are increasing, which implies that mapping from VLC entries to the corresponding entries used to initialize the VLC is monotonically increasing. This means that one can reuse the right end of the destination RL VLC to store the tables used to initialize the VLC with.

Andreas Rheinhardt	116e2a9ee2	avcodec/dv_tablegen, dvdata: Remove ff_dv_vlc_bits The codes can be easily calculated, so the table is unnecessary. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	2 years ago
Christophe Gisquet	05da586fef	dv: move inverse weight tables to decoder The encoder has its own tables and does not access the idct_factor member of the DVVideoContext structure. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Christophe Gisquet	80b29c2d0c	dv: use smaller type for weight tables Reviewed-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago

Diego Biurrun	3cbe112653	dv: Split DV data table declarations into their own header This is necessary to avoid target config settings bleeding into the host compilation process with hardcoded tables and the DV VLC tables no longer present as static tables in a header file.	11 years ago

Diego Biurrun	ba87f0801d	Remove explicit filename from Doxygen @file commands. Passing an explicit filename to this command is only necessary if the documentation in the @file block refers to a file different from the one the block resides in. Originally committed as revision 22921 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	10249a5f31	Split VLC-related tables out of dvdata.h to make it easier to add support for hard-coding tables. Originally committed as revision 22620 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	c76911bd65	Split parts of dvdata.h into dvdata.c, this ensures that things like work_chunks_* and dv_idct_factor_* variables appear only once in the binary instead of 3 times. Saves 3264 bytes in .rodata and 312416 bytes in .bss on x86_64. Originally committed as revision 20246 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 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.
