Return the flags which specify extensions supported by the CPU.
The returned value is affected by av_force_cpu_flags() if that was used before. So av_get_cpu_flags() can easily be used in a application to detect the enabled cpu flags.

| attribute_deprecated void av_set_cpu_flags_mask | ( | int | mask | ) |
Set a mask on flags returned by av_get_cpu_flags().
This function is mainly useful for testing. Please use av_force_cpu_flags() and av_get_cpu_flags() instead which are more flexible
| attribute_deprecated int av_parse_cpu_flags | ( | const char * | s | ) |
Parse CPU flags from a string.
The returned flags contain the specified flags as well as related unspecified flags.
This function exists only for compatibility with libav. Please use av_parse_cpu_caps() when possible.
| int av_parse_cpu_caps | ( | unsigned * | flags, |
