2021-03-11add floating-point PCM supoort to tinyplaydvdli
This change also fixes overwriting the appl_ptr and avail_min when calling the pcm_state function.
2021-02-22support float config and float wave file playbackdvdli
2021-01-28Let pcm_mmap_read/write call pcm_readi/writeidvdli
The pcm_readi and pcm_writei also can deal with the mmap read/write. Also mark the pcm_mmap_read/write functions as deprecated functions and update the test case. Add mmap playback support to tinyplay
2021-01-28prepare in pcm_generic_transferdvdli
2021-01-12remove pcm_prepare in pcm_opendvdli
For the dynamic pcm device, it is valid to specify the backend after opening it. However, it is invalid to call prepare on a dynamic pcm device without connecting any backend device. We should not do pcm_prepare in pcm_open. See also: Issue #197
2020-11-02calcuate the thresholds after options parsingdvdli
The period size and count may be changed after options parsing. We need to set proper threshoulds.
2020-11-02modify the buffer size to the period size to avoid underrundvdli
2020-10-29check whether the audio data are still enough to playdvdli

This could lead to playing out unwanted data which is placed at the end of file. authored-by: Patrick Lai <plai@codeaurora.org> Change-Id: I17bd3f6ebca4813f8987585472208c1f52696cae

2017-04-13Fix to pass num_frames to pcm_writeiJaikrishna Nemallapudi
pcm_writei expects size of data in frames, whereas currently size is passed as number of bytes. So convert number of bytes to frames for argument to pcm_writei.
