The attached patches add support to the dvb audio.h and video.h headers
for the Conexant cx23415 MPEG encoder/decoder. The encoder part is
handled in the V4L2 API, but the changes needed to fully support the
MPEG decoder are added to the DVB API through these patches.
These patches implement the 'RFC 0.3: MPEG encoding and decoding
V4L2/DVB API additions' posted last Sunday to this list.
The av7110.diff simply renames the VIDEO_CMD_* defines used in that
driver to the more specific AV_VIDEO_CMD_* defines. Otherwise they
would clash with the new VIDEO_CMD_* defines added to video.h.
The audiovideo.diff contains the actual API additions. These changes do
NOT break compatibility with existing applications. They only add new
functionality.
Oliver, can you sign off on these changes?
Thanks,
Hans
