[PATCH] v4l2: videobuf2-dc: fix support for mappings without struct page in userptr mode

Earlier version of dma-contig allocator in user ptr mode assumed that in
all cases DMA address equals physical address. This was just a special case.
Commit e15dab752d4c588544ccabdbe020a7cc092e23c8 introduced correct support
for converting userpage to dma address, but unfortunately it broke the
support for simple dma address = physical address for the case, when given
physical frame has no struct page associated with it (this happens if one
use for example dma_declare_coherent api or other reserved memory approach).
This commit restores support for such cases.

RE: HD Capture Card (HDMI and Component) output raw pixels

Hi Jim,

> I don't want to configure a RAID either, but if I purchase one SSD with
400 MB/sec write speeds, that might be good.

Hmm... nice idea.  Did you have any particular model in mind?  If you had a
link, I might be interested. I wouldn't know about sizing.  I don't know how
much space HD raw video takes up per hour, say.

On the other hand, maybe I could configure it to use the SSD for temporary
files while GStreamer did software compression.

Let me know what you think.

Regards

Steve

RE: HD Capture Card (HDMI and Component) output raw pixels

Hi Jim,

The Balckmagic Card does not seem to have any hardware compression, for me
that's a drawback, but if that's what you want it may be the right thing.

I want to avoid RAID 0 disks if I can.

It appears to be supported by Linux in the GStreamer bad pluggins, it's
called decklinksrc.  There is another allied one called the DeckLink mini
recorder also from Blackmagic PCIe for $145  it's on the same site, so you
might like to have a look at that too.

Blackmagic also provide a Linux SDK and some linux tools.  If you can't find
them I'll send you a link.

I'm going to buy one for testing over the next month or so, so if you want
to keep in touch, I'll let you know how it goes.

Regards

Steve

[PATCH v2 0/6] v4l-utils: v4l-utils: Fix satellite support in dvbv5-{scan,zap} tools

Hi all,

This set of patch fix sat support for dvbv5 libs and utils.
In this set, a different approach is used. The polarization parameter is stored in
the DTV_POLARIZATION property.

  Guy

Guy Martin (6):
  libdvbv5: Remove buggy parsing of extra DTV_foo parameters
  libdvbv5: Add parsing of POLARIZATION
  libdvbv5: Export dvb_fe_is_satellite()
  libdvbv5: Fix satellite handling and apply polarization parameter to
    the frontend
  libdvbv5: Use a temporary copy of the dvb parameters when tuning
  dvbv5-zap: Parse the LNB from the channel file
