From 04893043ae9ea8aa82b712491ed25ba6c4ffbca3 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Wed, 25 May 2011 12:24:48 -0300 Subject: [media] DocBook: Add rules to auto-generate some media docbook Auto-generate the videodev2.h.xml,frontend.h.xml and the indexes. Some logic at the Makefile helps us to identify when a symbol is missing, like for example: Error: no ID for constraint linkend: V4L2-PIX-FMT-JPGL.
