* armv6: Accelerate ff_fft_calc for general case (nbits != 4)Ben Avison2014-07-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | The previous implementation targeted DTS Coherent Acoustics, which only requires nbits == 4 (fft16()). This case was (and still is) linked directly rather than being indirected through ff_fft_calc_vfp(), but now the full range from radix-4 up to radix-65536 is available. This benefits other codecs such as AAC and AC3. The implementaion is based upon the C version, with each routine larger than radix-16 calling a hierarchy of smaller FFT functions, then performing a post-processing pass. This pass benefits a lot from loop unrolling to counter the long pipelines in the VFP. A relaxed calling standard also reduces the overhead of the call hierarchy, and avoiding the excessive inlining performed by GCC probably helps with I-cache utilisation too. I benchmarked the result by measuring the number of gperftools samples that hit anywhere in the AAC decoder (starting from aac_decode_frame()) or specifically in the FFT routines (fft4() to fft512() and pass()) for the same sample AAC stream: Before After Mean StdDev Mean StdDev Confidence Change Audio decode 2245.5 53.1 1599.6 43.8 100.0% +40.4% FFT routines 940.6 22.0 348.1 20.8 100.0% +170.2% Signed-off-by: Martin Storsjö <martin@martin.st>
* armv6: Accelerate ff_imdct_half for general case (mdct_bits != 6)Ben Avison2014-07-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | The previous implementation targeted DTS Coherent Acoustics, which only requires mdct_bits == 6. This relatively small size lent itself to unrolling the loops a small number of times, and encoding offsets calculated at assembly time within the load/store instructions of each iteration. In the more general case (codecs such as AAC and AC3) much larger arrays are used - mdct_bits == [8, 9, 11]. The old method does not scale for these cases, so more integer registers are used with non-unrolled versions of the loops (and with some stack spillage). The postrotation filter loop is still unrolled by a factor of 2 to permit the double-buffering of some VFP registers to facilitate overlap of neighbouring iterations. I benchmarked the result by measuring the number of gperftools samples that hit anywhere in the AAC decoder (starting from aac_decode_frame()) or specifically in ff_imdct_half_c / ff_imdct_half_vfp, for the same example AAC stream: Before After Mean StdDev Mean StdDev Confidence Change aac_decode_frame 2368.1 35.8 2117.2 35.3 100.0% +11.8% ff_imdct_half_* 457.5 22.4 251.2 16.2 100.0% +82.1% Signed-off-by: Martin Storsjö <martin@martin.st>

* mpegts: pass MpegTSContext ptr explicitlyAlexander V. Lukyanov2014-07-10
| | | | | | | | | | | | | | AVFormatContext->priv_data is not always a MpegTSContext, it can be RTSPState when decoding a RTP stream. So it is necessary to pass MpegTSContext pointer explicitly. Within libav, the write_section_data function doesn't actually use the MpegTSContext at all, so this doesn't change anything at the moment (no memory was corrupted before), but it reduces the risk of anybody trying to touch the MpegTSContext via AVFormatContext->priv_data in the future.

* af_compand: make sure request_frame always outputs at least one frameAndrew Kelley2014-07-08
| | | | | | | | | | | This fixes a segmentation fault because request_frame in fifo.c assumes that the call to ff_request_frame will populate fifo->root.next. Before, it was possible for request_frame in af_compand to not do this, resulting in a null pointer access. Now, request_frame in af_compand always will return at least one frame or an error, as per the API specifications in avfilter.h for request_frame. Signed-off-by: Anton Khirnov <anton@khirnov.net>

* libfdk-aacdec: Decode the first AAC frame to reliably identify the bitstreamOmer Osman2014-07-07
| | | | | | | | | | | | For implicit signaling cases (as possible for Spectral Band Replication and Parametric Stereo Tools), the decoder must decode the first frame to correctly identify the stream configuration (as called from avformat_find_stream_info). The mechanism for this is built-in and only requires adding CODEC_CAP_CHANNEL_CONF to the libfdk-aacdec AVCodec struct.
