| av_cold 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.

| av_cold 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.

Frees and resets MpegEncContext fields depending on the resolution as well as the slice thread contexts.
Is used during resolution changes to avoid a full reinitialization of the codec.
