Ronald S. Bultje	626964a4c4	wmall: fix build with -DDEBUG enabled.	13 years ago
Diego Biurrun	8ca6e523a6	wma: Refactor common code to fix standalone compilation of WMA lossless decoder.	13 years ago
Carl Eugen Hoyos	18794000c6	Remove AV_LOG_DEBUG from av_dlog() calls. AV_LOG_DEBUG is forced by the av_dlog definition.	13 years ago
Mashiat Sarker Shakkhar	9d25f1f619	Windows Media Audio Lossless decoder Decodes 16-bit WMA Lossless encoded files. 24-bit is not supported yet. Bitstream parser written by Andreas Öman with contributions from Baptiste Coudurier and Ulion. Includes a number of bug-fixes from Benjamin Larsson, Michael Niedermayer and Konstantin Shishkov, shine and polish by Diego Biurrun. Signed-off-by: Diego Biurrun <diego@biurrun.de>	13 years ago

Benjamin Larsson	7f215e3e72	Use fixed-length array in revert_mclms()	13 years ago
Mashiat Sarker Shakkhar	d1ea26f640	Do not try to read residue if ave_mean <= 1 Otherwise, we end up with with log(0) or log(1). av_ceil_log2 simply assumes the argument is non-zero and returns wrong result when it is. (Not that there is a proper way of returning an undefined value.)	13 years ago
Mashiat Sarker Shakkhar	59df25effd	Move some variable declarations to comply with C90	13 years ago

Mashiat Sarker Shakkhar	2083a10abf	Fix audio output Up until now, the decoder didn't output anything in the data buffer. This fixes all the issues related to sample format, removes leftover code and actually outputs some audio to data buffer. With this, the only sample we have can be played. Seeking is still broken though.	13 years ago
Mashiat Sarker Shakkhar	f7166f7d8d	Suppress dumping of residues buffer	13 years ago
Mashiat Sarker Shakkhar	3d84495128	Use quantizer value read from bitstream Currently the code initializes quantizer even before reading it from bitstream and uses that to dequantize samples.	13 years ago

Mashiat Sarker Shakkhar	075ebdf735	Move num_lms reading out of a loop	13 years ago
Mashiat Sarker Shakkhar	29c2fcb677	Use correct value for range The current range value causes an underflow when negated and pushes anything less than zero to the minimum.	13 years ago
Mashiat Sarker Shakkhar	768261e50d	Fix some int / int16_t / int32_t confusion For now force everything to int16_t, except for variables used as index	13 years ago

Michael Niedermayer	dae7ff0416	wmall: remove tabs that leaked in from a merge and seem to have managed to silently bypass the push checks. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Mashiat Sarker Shakkhar	be8a0d26db	Init s->cdlms[][].recent to order - 1 Not sure if this is correct. But looks like it was giving us off-by-one's when used to index buffers.	13 years ago
Mashiat Sarker Shakkhar	6dd19c97c4	Add a size argument to dump_int_buffer()	13 years ago
Mashiat Sarker Shakkhar	81a3c67169	Get rid of logging that are not required anymore (Resolves some conflicts)	13 years ago
Mashiat Sarker Shakkhar	e6c66fcf68	Fix some int vs. int16_t confusion Size should be determined from bits per sample. The current code only accepts 16-bit streams.	13 years ago
