[RFC PATCH v9] Refactoring Videobuf2 for common use

Hello everybody, This is the 9th round for refactoring Videobuf2(a.k.a VB2). The purpose of this patch series is to separate existing VB2 framework into core part and V4L2 specific part. So that not only V4L2 but also other frameworks can use them to manage buffer and utilize queue. Why do we

Hi, I can't get this dvb-t2 USB device to work despite the linuxtv site claiming it is working since 3.19 kernel. I tried talking to the driver team on IRC a few months ago and they said they would look at it but I have recently pulled the linuxtv git tree and compiled it on my Linux Mint 4.09

[v4l-utils 0/5] Misc build fixes

Hello, Here is a small set of fixes against v4l-utils that we have accumulated in the Buildroot project to fix a number of build issues. Those build issues are related to linking with the musl C library, or do linking with the libintl library when the gettext functions are not provided by the C

[v4l-utils 3/5] utils/v4l2-compliance: Include instead of

Code should not be including header, but instead it should include the public header. On glibc and uClibc, simply includes , but with the musl C library, it spits out a warning telling you that you're not doing the right thing: In file included from ./v4l-helpers.h:12:0, from

[v4l-utils 2/5] utils: Properly use ENABLE_NLS for locale related code

Various tools in utils/ use ENABLE_NLS to decide whether locale support is available or not, and only include if ENABLE_NLS is defined. However, they unconditionally use functions defined in such as setlocale(), bindtextdomain() or textdomain(), which causes build failures when the prototypes of

[v4l-utils 1/5] libv4lsyscall-priv.h: Use off_t instead of __off_t

__off_t is a kernel internal symbol, which happens to be user-visible with glibc, but not necessarily with other C libraries such as musl. In v4l-utils code, it's mainly used for the mmap() prototype, but the mmap() manpage really uses off_t, not __off_t. Switching from __off_t to off_t allows

[v4l-utils 4/5] libv4lsyscall-priv.h: Only define SYS_mmap2 if needed

The logic in libv4lsyscall-priv.h unconditionally defines SYS_mmap2 on Linux systems, but with current versions of C libraries, SYS_mmap2 is already defined, and therefore this additional definition causes some build warnings: In file included from processing/libv4lprocessing.h:24:0,
