* mlpdec: support TrueHD streams with an Atmos substreamHendrik Leppkes2015-03-11
| | | | | | | | | The fourth substream is being discarded, since its not raw audio data, but an encoded Atmos stream which needs a specialized decoder.

* truehd: break out part of output_data into platform-specific callback.Ben Avison2014-03-26
| | | | | | | Verified with profiling that this doesn't have a measurable effect upon overall performance. Signed-off-by: Martin Storsjö <martin@martin.st>
* truehd: tune VLC decoding for ARM.Ben Avison2014-03-26
| | | | | | | | | | | | | | | | | | | Profiling on a Raspberry Pi revealed the best performance to correspond with VLC_BITS = 5. Results for overall audio decode and the get_vlc2 function in particular are as follows: Before After Mean StdDev Mean StdDev Confidence Change 6:2 total 348.8 20.1 339.6 15.1 88.8% +2.7% (insignificant) 6:2 function 38.1 8.1 26.4 4.1 100.0% +44.5% 8:2 total 339.1 15.4 324.5 15.5 99.4% +4.5% 8:2 function 33.8 7.0 27.3 5.6 99.7% +23.6% 6:6 total 604.6 20.8 572.8 20.6 100.0% +5.6% 6:6 function 95.8 8.4 68.9 8.2 100.0% +39.1% 8:8 total 766.4 17.6 741.5 21.2 100.0% +3.4% 8:8 function 106.0 11.4 86.1 9.9 100.0% +23.1% Signed-off-by: Martin Storsjö <martin@martin.st>

* mlpdec: fix request_channel_layout behavior.Michael Niedermayer2014-02-08
| | | | | | | When request_channel_layout is 0, all substreams should be decoded. Signed-off-by: Tim Walker <tdskywalker@gmail.com>
* mlp: improve request_channel_layout behavior.Tim Walker2014-02-08
| | | | | | | | | | Don't decode further substreams if request_channel_layout is a subset of the current substream's channel_layout. Before, we would only discard further substreams if request_channel_layout matched the substream's channel_layout extactly, thus decoding additional channels which the caller would probably end up downmixing.
