Zhao Zhili	9e49915195	avcodec/mediacodecenc: Add global header support The extradata is generated by encoding a dummy frame, then reset the encoder state by mediacodec flush(). It only works for pixel format other than AV_PIX_FMT_MEDIACODEC, since I'm not sure how to create a dummy frame safely with AV_PIX_FMT_MEDIACODEC.

Zhao Zhili	98b5e80fd6	avcodec/mediacodec_wrapper: link to NDK mediacodec API directly Drop support of Android version before 5.0.	9 months ago
Zhao Zhili	309cff378c	configure: Lower Android API level requirement of mediandk AImage_delete is introduced in API level 24, while AMediaFormat_new is introduced in API level 21. We only need API level 21 to support NDK mediacodec. This change doesn't break or change of android_camera_indev since camera2ndk still needs API level 24.	9 months ago

Lynne	03cf101645	aacdec: remove AAC-specific MIPS optimizations The code was written in 2012, but seems to have been broken for just as long. Compilation is broken on every MIPS/MIPS64 system with an FPU (which the code depends on).	9 months ago

Lynne	eef9100a8e	aacdec: template LTP windowing separately The function is called only internally in DSP, so we do not need to expose it. apply_ltp on MIPS uses this function, but due to the function being just a glue function with no real optimizations, duplicate it there.	9 months ago

Andreas Rheinhardt	e3693c6f56	avcodec/aacdec_template: Deduplicate aac_decode_close() This is possible now that both AAC decoders share the same context. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	9 months ago
Andreas Rheinhardt	7117e0c7be	avcodec/aacdec: Use same AACDecContext for fixed and float Up until now, there was one AACDecContext for the fixed and one for the floating point decoder. These differed mostly in certain arrays which were int for the fixed-point and float for the floating point decoder; there were also differences in corresponding function pointers. Yet in order to deduplicate the enormous amount of currently duplicated code between the float and the fixed-point decoder, one needs common contexts. Given that int and float have the same size on all common systems, this commit replaces these arrays by unions of int arrays and of float arrays. The names of these arrays have been chosen to be compatible with AAC_RENAME(). Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	9 months ago
Andreas Rheinhardt	fc3c2ea8dc	avcodec/aacdec: PredictorState array out of SingleChannelElement sizeof(PredictorState) is different for the floating-point and the fixed-point AAC decoders; this is an obstacle for deduplicating code between these decoders. So don't include this array in SingleChannelElement, instead add a union of pointers to the fixed-point PredictorState and the floating-point PredictorState. The actual arrays are part of the extended ChannelElement to be allocated by ff_aac_sbr_ctx_alloc_init(); it also sets the pointers.

Andreas Rheinhardt	8b2261e573	avcodec/aacdec: Always include AV(Fixed\|Float)DSPContext in AACDecContext Up until now, AACDecContext included pointers to one of these contexts depending upon USE_FIXED. Yet deduplicating the common parts of the float and fixed-point AAC decoders needs common structures, so we put both of these pointers in a union.

Andreas Rheinhardt	5bd7b8d999	avcodec/aacdec: Split SBR context from ChannelElement The AAC fixed-point and floating-point decoders have a lot of duplicated code; the main obstacle to deduplicating it is that several structures with the same name are actually different types, because they contain INTFLOATs (int or float) and AAC_FLOATs (SoftFloat or float). SoftFloat and float typically have different sizes, so dealing with it is the more complicated of the two. AAC_FLOAT is mainly used in the sbr code and structures, so one can still deduplicate the code by only exposing the common part of ChannelElement (without SBR context) to the common decoder part. One prerequisite of this is to move allocating the whole ChannelElement to code that will stay unduplicated. It is most natural to move said allocation to ff_aac_sbr_ctx_init().
