| | * OpenSL ES: Fix buffer corruptionMichael Dippold2016-08-221-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When start is called, the buffer is always filled starting from index 0 without regard to m_nexBuffer. m_nextBuffer could be set to 1 from the previous playback which causes the second buffer to be filled first, which is now the currently playing buffer. This is causing an audible hiccup right after starting in cases where m_nextBuffer starts at 1.

* / Android: Improve detection of optimal settings for QAudioOutput.Christian Strømme2016-01-081-7/+24
|/ | | | | | | | | | | | | | | | | This change will try to detect the optimal buffer size and sample-rate on Android (requires API level 17+). If the device supports low-latency playback, then it's recommended that application developers check the preferred sample-rate through QAudioDeviceInfo::preferredFormat(). On most devices the preferred sample rate seems to be 48 KHz, so this is now the default instead of 44.1 KHz. Note that not all devices supports "proper" low-latency playback, and there are no APIs to retrieve information about how many devices that can be active at the same time; The only remotely quantitative value I've found is "a few"...

* OpenSL ES: improve buffer logicChristian Strømme2014-11-041-8/+26
| | | | | | | | | | | | | Don't use relaxed load and stores, we need to be stricter to avoid problems with high frequency re-fills of the buffer. If we don't enforce ordering we might end-up spending more time trying to acquire an open slot in the buffer. Updating processes bytes is also moved off the "OpenSL" thread. Added some comments for improved readability. Change-Id: Ie27965fc6bf4b8394081ae6419f4933522ada98e Reviewed-by: Yoann Lopes <yoann.lopes@theqtcompany.com>

* | OpenSL ES: Be less rigid about tearing down the output device.Christian Strømme2014-09-121-26/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | We where very strict about tearing down the audio device. While this is a good strategy to avoid unnecessary resource usage, it also causes excessive re-allocations, e.g., when transiting from start to stop and back again. This can increase latency, especially in case where a short clip is re-played at a high frequency. This change also decrease the chance of the player ending up in some unknown state where it drops audio clips without any warning.
