* Use gmtime_r instead of gmtime and localtime_r instead of localtimeMartin Storsjö2014-10-26
| | | | | | | | | | | gmtime isn't thread safe in general. In msvcrt (which lacks gmtime_r), the buffer used by gmtime is thread specific though. One call to localtime is left in avconv_opt.c, where thread safety shouldn't matter (instead of making avconv depend on the libavutil internal header).

* lavu: Provide fallbacks for gmtime_r and localtime_rMartin Storsjö2014-10-26
| | | | | | | | | | | | This allows writing most code as if they always are is available. These are ok to use from other libraries even though it's not a public header, since they only provide an inline declaration, and doesn't add an actual dependency on lavu internals. (This can be considered more a build system compatibility fallback than a libavutil feature.) Signed-off-by: Martin Storsjö <martin@martin.st>
* lavu: Add av_gettime_relativeMartin Storsjö2014-10-24
| | | | | | | | | | | | | | | | | | | Since av_gettime() is used in a number of places where actual real time clock is required, the monotonic clock introduced in ebef9f5a5 would have consequences that are hard to handle. Instead split it into a separate function that can be used in the cases where only relative time is desired. On platform where no monotonic clock is available, the difference between the two av_gettime functions is not clear, and one could mistakenly use the relative clock where an absolute one is required. Therefore add an offset, to make it evident that the time returned from av_gettime_relative never is actual current real time, even though it is based on av_gettime. Based on a patch by Olivier Langlois. Signed-off-by: Martin Storsjö <martin@martin.st>

| | | | | | | The rationale is that you have a packed format in form <greyscale sample> <alpha sample> <greyscale sample> <alpha sample> and shortening greyscale to 'G' might make one thing about Greenscale instead. An alias pixel format and color space name are provided for compatibility.

* arm: Detect 32 bit cpu features on ARMv8 when running on a 64 bit kernelMartin Storsjö2014-06-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | When running on a 64 bit kernel, /proc/cpuinfo lists different optional features than on 32 bit kernels (because some of them are mandatory in the 64 bit implemenations). The kernel does list the old features properly if they are queried via /proc/self/auxv though - however this file is not always readable (e.g. on most android systems). The getauxval function could also provide the same info as /proc/self/auxv even if this file isn't readable, but this function is not always available (and thus would need to be loaded with dlsym for compatibility with older android versions). The android cpufeatures library does this slightly differently, by assuming that these are available if the "CPU architecture" line is >= 8, see [1] for details. It has been suggested to include the old, non-optional features in /proc/cpuinfo as well, but that suggested patch never was merged. See [2] for the discussion around this suggestion.
