| void ff_mpv_common_defaults | ( | MpegEncContext * | s | ) |
Set the given MpegEncContext to common defaults (same for encoding and decoding).
The changed fields will not depend upon the prior state of the MpegEncContext.

| int ff_mpv_init_duplicate_contexts | ( | MpegEncContext * | s | ) |
Initialize an MpegEncContext's thread contexts.
Presumes that slice_context_count is already set and that all the fields that are freed/reset in free_duplicate_context() are NULL.
