[alsa-devel] Compressed Audio Playback/Capture through ALSA framework
by Patrick Lai 22 Mar '11

22 Mar '11

Hi, Is there a precedent for playback/capture compressed audio stream through ALSA playback/capture interface if underlying hardware supports decoder + sink & encoder + source capabilities? Which source file can I find an example? Thanks Patrick -- Sent by an employee of the Qualcomm Innovation Center, Inc. The Qualcomm Innovation Center, Inc. is a member of the Code Aurora Forum.
