AVFilterBufferRef* avfilter_ref_buffer | ( | AVFilterBufferRef * | ref, |
int | pmask | ||

void avfilter_unref_buffer | ( | AVFilterBufferRef * | ref) |
Remove a reference to a buffer.
If this is the last reference to the buffer, the buffer itself is also automatically freed.
ref | reference to the buffer, may be NULL |
