Subject: User data propagation for video codecs
Date: Fri, 13 Sep 2013 21:54:15 -0000 [thread overview]
Message-ID: <79eef80b5fa29d83a7ae9a3f7d83cea8.squirrel@www.codeaurora.org> (raw)
Hi
For video decoder, our video driver, which is V4l2 based, exposes two
capabilities:
1. V4L2_BUF_TYPE_VIDEO_OUTPUT_MPLANE for transaction of compressed buffers.
2. V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE for transaction of
decoded/uncompressed buffers.
We have a requirement to propagate "user specific data" from compressed
buffer to uncompressed buffer. We are not able to find any field in
"struct v4l2_buffer" which can be used for this purpose. Please suggest if
this can be achieved with current V4L2 framework.
Thanks
Vinay
