Andreas Rheinhardt	b8c45bbcbc	libavcodec/cbs: Stop needlessly reallocating the units array Currently, a fragment's unit array is constantly reallocated during splitting of a packet. This commit changes this: One can keep the units array by distinguishing between the number of allocated and the number of valid units in the units array. The more units a packet is split into, the bigger the benefit. So MPEG-2 benefits the most; for a video coming from an NTSC-DVD (usually 32 units per frame) the average cost of cbs_insert_unit (for a single unit) went down from 6717 decicycles to 450 decicycles (based upon 10 runs with 4194304 runs each); if each packet consists of only one unit, it went down from 2425 to 448; for a H.264 video where most packets contain nine units, it went from 4431 to 450.

Mark Thompson	ce5870a3a8	cbs: Refcount all the things! This makes it easier for users of the CBS API to get alloc/free right - all subelements use the buffer API so that it's clear how to free them. It also allows eliding some redundant copies: the packet -> fragment copy disappears after this change if the input packet is refcounted, and more codec-specific cases are now possible (but not included in this patch).	7 years ago
Mark Thompson	2651352988	cbs: Allocate the context inside the init function ... instead of making callers allocate it themselves. This is more consistent with other APIs in libav.	7 years ago

Mark Thompson	c42b62d1f9	h264_metadata: Fix double-free Whether the udu string should be freed depends on whether the SEI it gets added to was created internally by cbs or externally by the bsf. The current code frees it twice in the former case.	8 years ago
