From 8cbde94be34f95c01515ba19ce32bcd51ab3949e Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Sat, 24 Jun 2006 14:36:02 -0300 Subject: V4L/DVB (4223): Add V4L2_CID_MPEG_STREAM_VBI_FMT control V4L2_CID_MPEG_STREAM_VBI_FMT controls if and how VBI data is embedded in an MPEG stream. Currently only one format is supported: the format designed for the ivtv driver. This should be extended with new standard formats (such as defined for DVB) in the future.
