From 2c11d1bdfc7175cc75a603e433367caaf038ab69 Mon Sep 17 00:00:00 2001 From: Philipp Zabel Date: Thu, 2 Oct 2014 14:08:28 -0300 Subject: [media] coda: add coda_video_device descriptors Each video device descriptor determines the name, callback ops, and input and output formats on the corresponding video device. This simplifies coda_enum_fmt and coda_try_fmt a bit and will simplify adding separate video devices for JPEG codecs due to the slightly different behavior in the CodaDx6/CODA7542 case and a separate hardware unit on CODA960.
