* commit 'ffa190d0479d2370dd89c95692f822cbff2cc24c':
Move VLC and RL_VLC_ELEM structure definitions to a separate header

* commit '5c31eaa9998b2185e0aa04d11adff128498dc14a':
Remove unnecessary get_bits.h #includes and add missing headers where needed.
Merged-by: Clément Bœsch <clement@stupeflix.com>
|
|
Use the newly created vlc.h directly instead of including get_bits when needed.
The VLC and RL_VLC_ELEM structures are independent from the bitreader.

ff_huff_build_tree uses qsort underneath. AV_QSORT is substantially
faster due to the inlining of the comparison callback. Furthermore, this
code is reasonably performance critical, since in e.g the fraps codec,
ff_huff_build_tree is called on every frame. This routine is also called
in vp6 on every frame in some circumstances.
Sample benchmark (x86-64, Haswell, GNU/Linux), vp6 from FATE:
vp6 (old):
78930 decicycles in qsort, 1 runs, 0 skips
45330 decicycles in qsort, 2 runs, 0 skips
27825 decicycles in qsort, 4 runs, 0 skips

This is probably not the simplest solution but as this is needed for a bugfix,
simplification is left for later.

I have no idea what the idea was behind the original code,
but the new code is equivalent to it.
In that loop that places the new node nodes[j] contains
always the data of the new node (since the steps are always
in order: FFSWAP copies node[j] to node[j-1], j is decremented).
Thus nodes[j].no == i and nodes[j].sym == HNODE.
make fate still passes and contains VP6 samples which use
FF_HUFFMAN_FLAG_HNODE_FIRST.

Passing an explicit filename to this command is only necessary if the
documentation in the @file block refers to a file different from the
one the block resides in.
