Andreas Rheinhardt	496ff9f2e5	avcodec/[e]ac3enc: Don't invade CONFIG_ namespace Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>	4 years ago
Andreas Rheinhardt	505d4de064	avcodec/[e]ac3enc: Make encoders init-threadsafe, fix race ff_eac3_exponent_init() set values twice when initializing a static table; ergo the initialization code must not run concurrently with a running EAC-3 encoder. Yet this code is executed every time an EAC-3 encoder is initialized. So use ff_thread_once() for this and also for a similar initialization performed for all AC-3 encoders to make them all init-threadsafe.

Andreas Rheinhardt	f4e6aa609d	avcodec/ac3enc_float, eac3enc: Fix leaks on init error The AC-3 encoders (both floating- as well as fixed-point) as well as the EAC-3 encoder share code: All use ff_ac3_encode_init() as well as ff_ac3_encode_close(). Until `ee726e777b` ff_ac3_encode_init() called ff_ac3_encode_close() to clean up on error. Said commit removed this and instead set the FF_CODEC_CAP_INIT_CLEANUP flag; but it did the latter only for the fixed-point AC-3 encoder and not for the other two users of ff_ac3_encode_init(). This caused any already allocated buffer to leak upon a subsequent error for the two other encoders. This commit fixes this by adding the FF_CODEC_CAP_INIT_CLEANUP flag to the other two encoders using ff_ac3_encode_init(). Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>	4 years ago

Ronald S. Bultje	b170b323e3	ac3: don't use different names for option tables in the template file. The variables which are declared in the teplate file are static and therefore there is no symbol clash.	13 years ago

Justin Ruggles	953302656a	cosmetics: indentation	14 years ago
Justin Ruggles	08a747afb9	eac3enc: use frame exponent strategy when applicable. This checks if the set of selected exponent strategies for all blocks in a channel are in the frame exponent strategy table, and if so, writes the table index instead of each strategy. This saves up to 7 bits per channel per frame, so the overall effect on quality is small.	14 years ago

Justin Ruggles	8683c6a638	ac3enc: move ff_ac3_encode_frame() to ac3enc_template.c This avoids using function pointers for quite a few small functions, most of which just call DSP functions.	14 years ago
Justin Ruggles	e0cc66df61	ac3enc: split templated float vs. fixed functions into a separate file. Function pointers are used for templated functions instead of needlessly duplicating many functions.	14 years ago
