| | | | | | Despite being marked as restrict (and const for src) to mark the pointers as being non-aliased, it seems the compiler optimizes better this way. | ||||
* | Avoid using pa_stream_begin_write with PulseAudio | Chris Robinson | 2018-03-14 | 1 | -23/+9 |
| | | | | | | | | | | | | | It seems to actually have a negative performance impact when the system is under load. Without having actual measurements for any potential benefits, simply go with the recommended (and previous fallback) method of allocating space for the write and passing the free method. Ideally some kind of ring buffer could be used, so rather than constantly allocating and freeing blocks of memory, it uses the same memory over again with the callback marking each one as reusable. Unfortunately the callback isn't given much information to work with, and the update size (minreq) can potentially change during playback, which complicates things. | ||||

* | Don't check for space in the ringbuffer before trying to write | Chris Robinson | 2018-03-03 | 5 | -19/+10 |

* | Ensure at least the specified ringbuffer size is writable | Chris Robinson | 2018-03-02 | 10 | -51/+65 |
| | | | | | | Previously, all but one of the specified size could be written (so for a size of n, only n-1 was guaranteed writable). All users pretty much compensated for this, but it makes more sense to fix it at the source. | ||||
