initialize pcm_config to zero
|
|
sw_params ioctl() is failing with 'invalid parameter' error
since pointer to pcm_config passed from tinyplay is not zero
initialized, hence invalid values are passed for some
parameters.

It is sometimes useful for testing to be able to stream the
captured PCM to another tool instead of being forced to save
it to a WAV file.
Using '--' instead of the target filename will send the raw
PCM to stdout (without any header).

'byte_rate' and 'block_align' sections of the WAV header were calculated
using an invalid 'bits_per_sample' value. 'bits_per_sample' is now set
before it gets used by other fields.

Command-line arguments are added for:
tinyplay and tinycap:
-D n -- card number
-p n -- period size
-n n -- number of periods per buffer
tinymix:
-D n -- card number

In several places, argv is incremented and *argv is dereferenced
without checking to see if it is valid to do so. This could lead to a
buffer overrun if the user provides invalid parameters.
This patch generally changes this:
if (strcmp(*argv, "-r") == 0) {
argv++;
rate = atoi(*argv);
}
argv++;
To this:
if (strcmp(*argv, "-r") == 0) {
argv++;
if (*argv)
rate = atoi(*argv);
}
if (*argv)
argv++;

Fixes tinyplay and tinycap after a recent change to allow
threasholds to be set in the pcm module.

This adds a utility to capture audio with a specified number of
parameters. Capturing continues until a signal is received
(ctrl-c).
