From a8bbf12ad8a8ad532cea0b67f0127ad90d336b04 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Mon, 9 Jan 2006 15:25:42 -0200 Subject: V4L/DVB (3249): Generalized cx25840 video/audio input handling - Added VIDIOC_S_AUDIO to set the audio inputs separately. - Removed AUDC_SET_INPUT. - Made the video inputs much more general. - Removed cardtype CID and replaced with a CID to enable the PVR150 workaround. The cardtype is no longer necessary with the general video input change. - Update VIDIOC_LOG_STATUS output to show the video and audio inputs separately.
