Jakub Stachowski	8501bed08c	Don't restrict reverse decorrelation to both coded channels. It is also used for mono data. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Jakub Stachowski	035a394eac	WMAL: do not output last frame again if nothing was decoded in current packet Reviewed-by: Mashiat Sarker Shakkhar <mashiat.sarker@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at> Signed-off-by: Kostya Shishkov <kostya.shishkov@gmail.com>	13 years ago
Mashiat Sarker Shakkhar	f92f452378	WMAL: do not start decoding if frame does not end in current packet This fixes decoding of frames which span more than two packets. Tested with recit24.wma. Signed-off-by: Kostya Shishkov <kostya.shishkov@gmail.com>	13 years ago
Jakub Stachowski	93bf1aac6a	wmalossless: Ensure that last frame is not written again if nothing was decoded in current packet. Reviewed-by: Mashiat Sarker Shakkhar <mashiat.sarker@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Jakub Stachowski	56dcfe87ef	Clear residues only in not coded channel. This fixes overwriting coded residues with zeros if first channel is coded and second is not. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	64bd7f8e4d	wmalosslessdec: Reset put bit buffer when num_saved_bits is reset. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago

Mashiat Sarker Shakkhar	2e13f57993	wmal: Warn about missing bitstream splicing feature and ask for sample. Signed-off-by: Diego Biurrun <diego@biurrun.de>	13 years ago
Mashiat Sarker Shakkhar	9900dd2d9c	wmal: Skip seekable_frame_in_packet. There is no point in storing the value in a variable, since it is not used anywhere else in the decoder. Signed-off-by: Diego Biurrun <diego@biurrun.de>	13 years ago
Mashiat Sarker Shakkhar	07933b44dd	wmal: Drop unused variable num_possible_block_size. This is probably a leftover from WMA Pro. Signed-off-by: Diego Biurrun <diego@biurrun.de>	13 years ago

Michael Niedermayer	d442c4462a	wmalosslessdec: Make arrays WMALL_BLOCK_MAX_SIZE big and check samples_per_frame. The samples_per_frame check is ported from wmaprodec.c Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	680097cb6d	WMAL: Do not try to read rawpcm coefficients if bits is invalid Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Jakub Stachowski	3b00fd5985	wmalosslessdec: Reset residues to 0 if they were not decoded from bitstream. If channel residues are have not been decoded from bitstream, they should be initialized to 0 instead of using values from previous subframe. This causes bursts of noise in silent parts of some files.

Michael Niedermayer	d0212bb032	wmalosslessdec: channel residues can be 32 bit thus need _long bitreader. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Mashiat Sarker Shakkhar	28e8c4d59a	WMAL: Remove inaccurate and unnecessary doxy A call to decode_packet() does not always decode a complete WMA packet.

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	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
