STOP ioctl should not wait for result. STATUS or poll() should be used to wait for the task operation.

Thank you for this example code, but the abstraction should be added to tinycompress library like we do for standard playback/capture modes. |

heh! GH doesnt let comment on patchlog...
I guess it would make sense to say, move the header to version 0.3.0...

This should be folded into previos patch as both are coming from kernel header

should we always build caccel?
yes, that is the primary comment for this change |
Merge header file compress_offload.h for the changes of adding accel operation. Merge header file compress_params.h for the changes of adding src codec. update libtinycompress for adding accel operations. Signed-off-by: Shengjiu Wang <shengjiu.wang@nxp.com>
This 'caccel' applicaton is a demo to show how to call the new introduced accel interface. The kernel patch is: ALSA: compress_offload: introduce accel operation mode As there is conflict when using the API of alsa-lib, add alsa_wrap file to separate the header files: alsa/asoundlib.h sound/asound.h Signed-off-by: Shengjiu Wang <shengjiu.wang@nxp.com>

@perexg @vinodkoul I have update the commits, mainly for tinycompress library. |
This 'caccel' applicaton is a demo to show how to
call the new introduced accel interface.
The kernel patch is:
ALSA: compress_offload: introduce accel operation mode
As there is conflict when using the API of alsa-lib,
add alsa_wrap file to separate the header files:
alsa/asoundlib.h
sound/asound.h
command for conversion to 48kHz:
caccel -i in.wav -o out.wav -r 48000
