The passthrough decoding is handled by apps. Here is the snippet from the ffmpeg's 'svn log' ------------------------------------------------------------------------ r25760 | cehoyos | 2010-11-17 20:22:59 +0800 (Wed, 17 Nov 2010) | 6 lines Add support for IEC 61937 ("SPDIF") encapsulation for E-AC-3. Only works via HDMI. Patch by Anssi Hannula (anssi d hannula a iki d fi), based on some work by myself. ------------------------------------------------------------------------ You can search in ffmpeg's development's mailing list for more information. Thank you. _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
