[FFmpeg-devel] [PATCH 1/9] avfilter/bwdif: Add proper BWDIFDSPContext

[FFmpeg-devel] [PATCH 1/9] avfilter/bwdif: Add proper BWDIFDSPContext

[Andreas Rheinhardt]

This already avoids unnecessary indirectly included headers
in the arch-specific vf_bwdif_init.c files; it is also in
preparation for splitting the actual functions out of vf_bwdif.c.

[FFmpeg-devel] [PATCH 2/9] avfilter/vf_bwdif: Move DSP code to a new file

[Andreas Rheinhardt]

Otherwise checkasm/vf_bwdif.c pulls in vf_bwdif.c and
then all of libavfilter. Besides being bad size-wise
this also has the downside that it pulls in
avpriv_(cga|vga16)_font from libavutil which are marked
as being imported from another library when building
libavfilter as a DLL and this breaks checkasm because
it links both lavfi and lavu statically.

[FFmpeg-devel] [PATCH 4/9] avfilter/bwdifdsp: Avoid including ff_bwdif_filter_line3_c()

[Andreas Rheinhardt]

This function is used by the AARCH64 code to filter a few
remaining lines in case the dimensions are not suitably
aligned; it is furthermore also used by checkasm to actually
test the AARCH64 code against. But it is normally not used
and this patch therefore moves it in bwdifdsp.h as a static
inline function so that it can be avoided if possible
or inlined where necessary.

[FFmpeg-devel] [PATCH 5/9] checkasm/motion: Don't allocate AVCodecContext

[Andreas Rheinhardt]

Instead use one on the stack to avoid pulling in all
of libavcodec.

Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
---
ff_me_cmp_init() reads only codec_id (checks whether it is Snow)
as well as the bitexact flag. The first check has been added in
cfe675269bf44c49590e9076b5d2cd2503804f98 due to alignment;
I don't know whether this is still an issue, as the ticket referred
to in this commit does not refer to track (or at least the current
incarnation of it), but to something else.

[FFmpeg-devel] [PATCH 6/9] avcodec/snow: Split ff_snow_get_buffer()

[Andreas Rheinhardt]

The part of said function that is common to both encoder and decoder
is negligible since c954cf1e1b766a0d1992d5be0a8be0055a8e1a6a
and more than offset by the costs of "Am I an encoder?" checks.

So move allocating the frames to the encoder and decoder directly.
Also rename ff_snow_frame_start() to ff_snow_frames_prepare(),
because a frame without a buffer has not been properly started.

[FFmpeg-devel] [PATCH 7/9] avcodec/snow: Move decoder parts out of ff_snow_common_init_after_header

[Andreas Rheinhardt]

They are not common.

Furthermore, this file is pulled in when linking checkasm and
up until now, the calls to ff_get_buffer() and av_codec_is_decoder()
caused all of libavcodec to be pulled in as well. Besides being
bad size-wise this also has the downside that it pulls in
avpriv_(cga|vga16)_font from libavutil which are marked as
being imported from another library when building libavcodec
as a DLL; this breaks checkasm because it links both lavc and lavu
statically.

[FFmpeg-devel] [PATCH 8/9] avcodec/aacsbrdata: Move ff_sbr_noise_table to sbrdsp_template.c

[Andreas Rheinhardt]

ff_sbr_noise_table is only used by SBR DSP code
and sbrdsp.h is the header providing its declaration.

Furthermore, this ensures that checkasm does not pull
the whole AAC SBR and PS code in.
