* | lavd/v4l2: do not fail when VIDIOC_ENUMSTD returns ENODATAAndre Wolokita2014-08-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As of September 14 2012, v4l_enumstd() will return ENODATA when a device's std field is set to 0. That is, the device does not have a standard format. In order to properly handle this case, v4l2_set_parameters should catch the ENODATA code and break instead of failing. Below is the v4l2-core commit describing this change. >>commit a5338190efc7cfa8c99a6856342a77d21c9a05cf >>Author: Hans Verkuil <hans.verkuil@cisco.com> >>Date: Fri Sep 14 06:45:43 2012 -0300 >> >> [media] v4l2-core: tvnorms may be 0 for a given input, handle that case >> >> Currently the core code looks at tvnorms to see whether ENUMSTD >> or G_PARM should be enabled.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Whenever av_gettime() is used to measure relative period of time, av_gettime_relative() is prefered as it guarantee monotonic time on supported platforms. Since v4l2 is compiled only on Linux where av_gettime_relative() is monotonic, a small wrapper function av_gettime_monotonic() is used (should be inlined the compiler) to put emphasis on that fact.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With some (buggy) drivers, the VIDIOC_G_STD ioctl returns a std_id that cannot be matched with any of the enumerated v4l2_standard structures (for example std_id = 0 or std_id = 0xffffff). Do not fail when we reach the end of the enumeration without a valid match.
