| int av_parse_cpu_caps | ( | unsigned * | flags, | |
| const char * | s | |||

Parse CPU caps from a string and update the given AV_CPU_* flags based on that.

| 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.
| 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
