This patch did a cleanup following the commit "Save NEON registers
in VP8 NEON functions". The pushing/poping of callee-saved NEON
registers was moved into individual NEON functions. Therefore,
we don't need to save those registers at the beginning of codec.
The related code was removed.

this was never fleshed out in the context of VP8, for which it was
added. for VP9 it has no meaning.

Started adding support for multiple internal decoder instances. Also added
code to limit the vp8 config options available when using frame-based
multithreading.

When error concealment is enabled, it swaps the mi and prev_mi ptrs after
each frame is decoded. The postproc uses the mi ptr for the mode info context.
Now the postproc will use the correct mode info context.

Multiple decoders were getting allocated per frame.
If the decoder crashed we exitted with out freeing
them and the next time in we'd allocate over.
This fix removes the allocation and just has 8
boolcoders in the pbi structure

Interleaved loopfiltering with decode. For 1080p clips, up to 1%
performance gain. For 4k clips, up to 10% seen. This patch is required
for better "frame-based" multithreading.

After a key frame encoding, the frame type could change while
filtering is still going on. Pass the frame type as parameter to the
loopfilter function and don't read it from common storage.
vp8cx_set_alt_lf_level has to be done before packing the stream.
Currently alt_lf_level is not used so there hasn't been any visible
problem here.

The backup MODE_INFO buffer used in the error concealment was
allocated in the codec common parts allocation even though this is a
decoder only resource. Moved the allocation to the decoder side.
No need to update_mode_info_border as mode_info buffers are zero
allocated.
This fixes also a potential memory leak as the EC overlaps buffer was not
properly released before reallocation after a frame size change.

The block pointers and offset do not need to be calculated for every
frame. Block internal predictors can be update once when decoder is
allocated. Destination and previous buffer offsets have to be updated
just when frame size is changing.

This commit continues the process of converting to the new RTCD
system.
Change-Id: I6c519ab61e4f4e0ebcc796f2df061f945c48cefe
|
|
This is a proof of concept RTCD implementation to replace the current
system of nested includes, prototypes, INVOKE macros, etc. Currently
only the decoder specific functions are implemented in the new system.
Additional functions will be added in subsequent commits.
Overview:
RTCD "functions" are implemented as either a global function pointer
or a macro (when only one eligible specialization available).
Functions which have RTCD specializations are listed using a simple
DSL identifying the function's base name, its prototype, and the
architecture extensions that specializations are available for.
Advantages over the old system:
- No INVOKE macros. A call to an RTCD function looks like an ordinary
function call.
- No need to pass vtables around.
- If there is only one eligible function to call, the function is
called directly, rather than indirecting through a function pointer.
- Supports the notion of "required" extensions, so in combination with
the above, on x86_64 if the best function available is sse2 or lower
it will be called directly, since all x86_64 platforms implement
sse2.
- Elides all references to functions which will never be called, which
could reduce binary size. For example if sse2 is required and there
are both mmx and sse2 implementations of a certain function, the
code will have no link time references to the mmx code.
- Significantly easier to add a new function, just one file to edit.
Disadvantages:
- Requires global writable data (though this is not a new requirement)
- 1 new generated source file.

Commit 892e23a5b introduced support for the VP8D_GET_LAST_REF_USED,
but missed the mapping of the control id to the underlying function,
so it was unavailable to applications.
In addition, the underlying function vp8_references_buffer() is
moved from common/postproc.c to decoder/onyxd_if.c as postproc.c is
not built in all configurations.

A processor with ARMv7 instructions does not
necessarily have NEON dsp extensions. This CL
has the added side effect of allowing the ability
to enable/disable the dsp extensions cleanly.

Adding support for several partitions within one input fragment.
This is necessary to fully support all possible packetization
combinations in the VP8 RTP profile. Several partitions can
be transmitted in the same packet, and they can only be split
by reading the partition lengths from the bitstream.
Change-Id: If7d7ea331cc78cb7efd74c4a976b720c9a655463

These changes fixes a glitch between the RTP profile and the input
partitions interface. Since there's no way for the user to know the
actual number of partitions, the decoder have to read the
multi_token_paritition bits also when input partitions mode is
enabled.
Included are also a couple of fixes for issues with independent
partitions and uninitialized memory reads.

When error concealment is enabled the first key frame must
be successfully received before error concealment is activated.
Error concealment will be activated when the delta following
delta frame is received.
Also fixed a couple of bugs related to error tracking in
multi-threading. And avoiding decoding corrupt residual
when we have multiple non-resilient partitions.

sharpness was not recalculated in vp8cx_pick_filter_level_fast
remove last_filter_type. all values are calculated, don't need to update
the lfi data when it changes.
always use cm->sharpness_level. the extra indirection was annoying.
don't track last frame_type or sharpness_level manually. frame type
only matters for motion search and sharpness_level is taken care of in
frame_init
move function declarations to their proper header

Separate simple filter with reduced no. of parameters.
MB filter level picking based on precalculated table. Level table updated for
each frame. Inside and edge limits precalculated and updated just when
sharpness changes. HEV threshhold is constant.
ARM targets use scalars and others vectors.
Change works only with --target=generic-gnu
All other targets have to be updated!

With this commit frames can be received partition-by-partition
from the encoder and passed partition-by-partition to the
decoder.
At the encoder-side this makes it easier to split encoded
frames at partition boundaries, useful when packetizing
frames. When VPX_CODEC_USE_OUTPUT_PARTITION is enabled,
several VPX_CODEC_CX_FRAME_PKT packets will be returned
from vpx_codec_get_cx_data(), containing one partition
each. The partition_id (starting at 0) specifies the decoding
order of the partitions. All partitions but the last has
the VPX_FRAME_IS_FRAGMENT flag set.
At the decoder this opens up the possibility of decoding partition
N even though partition N-1 was lost (given that independent
partitioning has been enabled in the encoder) if more info
about the missing parts of the stream is available through
external signaling.
Each partition is passed to the decoder through the
vpx_codec_decode() function, with the data pointer pointing
to the start of the partition, and with data_sz equal to the
size of the partition. Missing partitions can be signaled to
the decoder by setting data != NULL and data_sz = 0. When
all partitions have been given to the decoder "end of data"
should be signaled by calling vpx_codec_decode() with
data = NULL and data_sz = 0.
The first partition is the first partition according to the
VP8 bitstream + the uncompressed data chunk + DCT address
offsets if multiple residual partitions are used.

The error-concealer is plugged in after any motion vectors have been
decoded. It tries to estimate any missing motion vectors from the
motion vectors of the previous frame. Intra blocks with missing
residual are replaced with inter blocks with estimated motion vectors.
This feature was developed in a separate sandbox
(sandbox/holmer/error-concealment).

A large number of functions were defined with external linkage, even
though they were only used from within one file. This patch changes
their linkage to static and removes the vp8_ prefix from their names,
which should make it more obvious to the reader that the function is
contained within the current translation unit. Functions that were
not referenced were removed.
These symbols were identified by:
$ nm -A libvpx.a | sort -k3 | uniq -c -f2 | grep ' [A-Z] ' \
| sort | grep '^ *1 '
