5 years agovc-1: Optimise parser (with special attention to ARM)
Ben Avison [Mon, 21 Jul 2014 13:53:09 +0000 (14:53 +0100)]
vc-1: Optimise parser (with special attention to ARM)

The previous implementation of the parser made four passes over each input
buffer (reduced to two if the container format already guaranteed the input
buffer corresponded to frames, such as with MKV). But these buffers are
often 200K in size, certainly enough to flush the data out of L1 cache, and
for many CPUs, all the way out to main memory. The passes were:

1) locate frame boundaries (not needed for MKV etc)
2) copy the data into a contiguous block (not needed for MKV etc)
3) locate the start codes within each frame
4) unescape the data between start codes

After this, the unescaped data was parsed to extract certain header fields,
but because the unescape operation was so large, this was usually also
effectively operating on uncached memory. Most of the unescaped data was
simply thrown away and never processed further. Only step 2 - because it
used memcpy - was using prefetch, making things even worse.

This patch reorganises these steps so that, aside from the copying, the
operations are performed in parallel, maximising cache utilisation. No more
than the worst-case number of bytes needed for header parsing is unescaped.
Most of the data is, in practice, only read in order to search for a start
code, for which optimised implementations already existed in the H264 codec
(notably the ARM version uses prefetch, so we end up doing both remaining
passes at maximum speed). For MKV files, we know when we've found the last
start code of interest in a given frame, so we are able to avoid doing even
that one remaining pass for most of the buffer.

In some use-cases (such as the Raspberry Pi) video decode is handled by the
GPU, but the entire elementary stream is still fed through the parser to
pick out certain elements of the header which are necessary to manage the
decode process. As you might expect, in these cases, the performance of the
parser is significant.

To measure parser performance, I used the same VC-1 elementary stream in
either an MPEG-2 transport stream or a MKV file, and fed it through avconv
with -c:v copy -c:a copy -f null. These are the gperftools counts for
those streams, both filtered to only include vc1_parse() and its callees,
and unfiltered (to include the whole binary). Lower numbers are better:

                Before          After
File  Filtered  Mean   StdDev   Mean   StdDev  Confidence  Change
M2TS  No        861.7  8.2      650.5  8.1     100.0%      +32.5%
MKV   No        868.9  7.4      731.7  9.0     100.0%      +18.8%
M2TS  Yes       250.0  11.2     27.2   3.4     100.0%      +817.9%
MKV   Yes       149.0  12.8     1.7    0.8     100.0%      +8526.3%

Yes, that last case shows vc1_parse() running 86 times faster! The M2TS
case does show a larger absolute improvement though, since it was worse
to begin with.

This patch has been tested with the FATE suite (albeit on x86 for speed).

fate: support testing of release branches

Adding 'branch=release/10' to the fate config file will check the
release/10 branch instead of master. If no branch is specified it will
use 'master' so that existing config are still valid.

The server side changes are already deployed, see
https://fate.libav.org/v10/ for an example. The server supports only the
release/* branches.

The server enforces that a single slot tests always the same branch.
Please append "-v$RELEASE" to the slot of release branch configs or make
the slot otherwise unique.

A different fate samples dir is needed for each release branch. make
