As discussed on the media summit 2013, there is no reason for the width

Therefore this patch is an attempt to convert those fields from __s32 to

Hello there!
I am new to IPTV and Video4Linux. I need to implement an IPTV solution that
would stream DVB satellite channels in a network. What is the satellite
receiver do you recommend me to use on my Linux Centos 6.4 server? The
satellite receiver should support encrypted channels. Is it bett

Hello Marek
Could you review the patch? Is there something that needs to be fixed?
Thanks!

Exynos4x12 has limitations regarding setting chroma subsampling
of an output JPEG image. It cannot be lower than the subsampling
of the raw source image. Also in case of V4L2_JPEG_CHROMA_SUBSAMPLING_GRAY
option the source image fourcc has to be V4L2_PIX_FMT_GREY.

Whereas S5PC210 device produces decoded JPEG subsampling
values that map on V4L2_JPEG_CHROMA_SUBSAMPLNG values,
the Exynos4x12 device doesn't. This patch adds helper

Adjust capture format to the Exynos4x12 device limitations,
according to the subsampling value parsed from the source
JPEG image header. If the capture format was set to YUV with
subsampling lower than the one of the source JPEG image
the decoding process would not succeed.

Aligning capture queue image dimensions while enqueuing output
queue doesn't make a sense as the S_FMT ioctl might have not
been called for the capture queue until that moment, whereas
it is required to know capture format as the type of alignment
heavily depends on it.

vb2_fop_release does not held the lock although it is modifying the

This could lead to race conditions on the vb2_perform_io function

Finally! It's producing an OK result. It's been a long, long time since we
