Function Documentation

static void validate_thread_parameters ( AVCodecContext *  avctx )

static

Set the threading algorithms used.

Threading requires more than one thread. Frame threading requires entire frames to be passed to the codec, and introduces extra decoding delay, so is incompatible with low_delay.

Parameters

avctx

The context.
