* pcm_resample: return NULL on failureMax Kellermann2009-03-141-4/+4
| | | | Changed "0" to "NULL".
* all: Update copyright header.Avuton Olrich2009-03-131-7/+7
| | | | | | | | This updates the copyright header to all be the same, which is pretty much an update of where to mail request for a copy of the GPL and the years of the MPD project. This also puts all committers under 'The Music Player Project' umbrella. These entries should go individually in the AUTHORS file, for consistancy.
* pcm_resample: use 24 bit resampling code for 32 bit samplesMax Kellermann2009-03-021-1/+1
| | | | | Resampling 32 bit samples is the same as resampling 24 bit samples - both are stored in the int32_t type.
* conf: replaced getConfigParamValue() with config_get_string()Max Kellermann2009-01-171-1/+1
| | | | Don't return a writable pointer.
* added missing explicit config.h includesMax Kellermann2009-01-081-0/+1

* pcm_resample: use pcm_buffer (2/2)Max Kellermann2009-01-081-16/+6
| | | | Use the PCM buffer library for the libsamplerate output buffer.
* pcm_resample: use pcm_buffer (1/2)Max Kellermann2009-01-081-15/+22
| | | | Return a temporary buffer from pcm_resample_*() and pcm_convert().
* pcm: added pcm_convert_deinit(), pcm_resample_deinit()Max Kellermann2009-01-071-0/+7
| | | | | Free memory allocated by libsamplerate when the output or the decoder is closed.
* pcm: use GLib instead of utils.hMax Kellermann2009-01-031-5/+4
|
* pcm: use GLib loggingMax Kellermann2008-12-291-12/+16

* pcm_resample: support for libsamplerate < 0.1.3Max Kellermann2008-10-241-0/+20
| | | | | libsamplerate 0.1.2 didn't have the 32 bit <-> float conversion routines. Emulate them in case they aren't supported.
* pcm_resample: implemented 24 bit resamplingMax Kellermann2008-10-231-0/+53
| | | | | | | Similar to pcm_resample_16(), implement pcm_resample_24(). The 24 bit implementation is very similar, but it uses src_int_to_float_array() instead of src_short_to_float_array() before sending data to libsamplerate.
* pcm_resample: moved code to pcm_resample_set()Max Kellermann2008-10-231-29/+40
| | | | | A future patch will implement a 24 bit resampler. To unify code, move code which can be shared to a separate function.
* pcm_resample: don't resample partial samplesMax Kellermann2008-10-231-0/+4
| | | | | Added assertions which ensure that there are no partial samples in the source buffer.
* pcm_resample: don't hard-code sample sizeMax Kellermann2008-10-231-3/+3
| | | | | | Use sizeof(sample) instead of hard-coding "2". Although we're in 16 bit right now, this will make code sharing easier when we support other sample sizes.
* pcm_utils: moved code to pcm_resample.cMax Kellermann2008-10-231-0/+140
Separate the resampling code from the rest of pcm_utils.c. Create two sub-libraries: pcm_resample_libsamplerate.c and pcm_resample_fallback.c.
