Anton Khirnov 1d0feb5d1a mpegvideo: split ff_draw_horiz_band(). 
Split out dependency on MpegEncContext.
 2013-02-15 16:10:19 +01:00
Anton Khirnov 54974c6298 error_resilience: decouple ER from MpegEncContext 2013-02-15 16:10:11 +01:00
Anton Khirnov d9ebb00dcb svq3: remove a pointless if() 
The H264 context is always uninitialized at this point.
 2013-02-15 16:09:52 +01:00
Anton Khirnov 2491f9ee29 h264: remove a pointless if() 
!encoding is always true, we do not have a H.264 encoder
 2013-02-15 16:09:45 +01:00
Anton Khirnov 68f930d218 h264: simplify calls to ff_er_add_slice(). 
partitioned_frame is never set for h264 (as easily seen from git grep).
 2013-02-15 16:09:37 +01:00
Anton Khirnov d2a25c4032 get_buffer(): do not initialize the data. 
There may be more decoders that rely on this. Those should be found and
fixed.
 2013-02-15 16:08:44 +01:00
Anton Khirnov 64ed397635 vf_yadif: fix out-of line reads 
Some changes in the border pixels, visually indistinguishable.
 2013-02-15 16:08:33 +01:00
Anton Khirnov ccd70d9c16 vf_yadif: factorize initializing the filtering callbacks 
Do it all in config_props().

Anton Khirnov 81726a4f0b FATE: add tests for additional flavors of asf cover art 2013-02-09 18:57:21 +01:00
Anton Khirnov 1ef0e8a6bf asfdec: do not assume every AVStream has a corresponding ASFStream 
This won't be true for ID3 attached picture.

Also stop allocating now useless dummy ASFStreams for ASF native
attached pictures.
 2013-02-09 18:57:21 +01:00
Anton Khirnov 12b54a1f39 mpegvideo: remove an unused function parameter 2013-02-06 21:48:48 +01:00
Anton Khirnov 605b047bcc rv10: improve buffer size check. 
Check slice count and input buffer size before constructing a possibly
invalid pointer, not after.
 2013-02-06 21:47:57 +01:00
Anton Khirnov c5fcdb4402 error_resilience: remove a useless if() and FIXME 
pp_time is never set for h264
 2013-02-06 21:46:55 +01:00
Anton Khirnov 9782c778a2 h264: remove silly macros 
They serve no useful purpose and wreak all kind of havoc when h264.h is
included elsewhere.
 2013-02-06 21:45:02 +01:00
Anton Khirnov ca1fe6c0e6 h263: remove an unused parameter from ff_h263_decode_init_vlc 2013-02-06 21:44:38 +01:00
Anton Khirnov 293065bdb5 mpegvideo: initialize dummy reference frames. 
Do not rely on get_buffer initializing them.

Changes yadif tests (off by one in one border pixel), because yadif
reads from those uninitialized lines.
 2013-02-06 10:21:52 +01:00
Anton Khirnov dff6197dfb nuv: do not rely on get_buffer() initializing the frame. 2013-02-06 10:21:52 +01:00
Anton Khirnov 39a9fdd00f yop: initialize palette to 0 
The FATE sample contains some pixels with value 0, but the palette
stored in the file contains only values from 16 up. Because the default
and cmdutils get_buffer() initialize the data to 0x80, they appear as
gray dots.
After this commit they change to black dots, which is probably still
incorrect but less visible and doesn't rely on get_buffer() initializing
the data.
 2013-02-06 10:21:52 +01:00
Anton Khirnov 8136f23444 yop: check for input overreads. 
CC:libav-stable@libav.org
 2013-02-06 10:21:52 +01:00
Anton Khirnov 06cf597c35 yop: check that extradata is large enough.

Anton Khirnov da7baaaae7 aasc: fix output for msrle compression. 
The bottom line was invalid before.

 2013-02-06 10:21:52 +01:00
Anton Khirnov 6a39985451 cmdutils: remove ansi from the list of broken codecs. 
It's not relying on get_buffer() initializing the frame since
99e36ddd3e.
 2013-02-06 10:21:52 +01:00
Anton Khirnov 238614de67 cdgraphics: do not rely on get_buffer() initializing the frame. 
Setting it to zero (instead of 128, as the default get_buffer() does)
also produces more correctly-looking output.
 2013-02-06 10:21:52 +01:00
Anton Khirnov 6ed9fc44ba svq1: replace struct svq1_frame_size with an array. 
It is used as an array in svq1enc, so this is more correct.
 2013-02-06 10:21:52 +01:00
Anton Khirnov 99162f8d46 vf_yadif: silence a warning. 
clang says:
libavfilter/vf_yadif.c:192:28: warning: incompatible pointer types assigning to
'void (*)(uint8_t *, uint8_t *, uint8_t *, uint8_t *, int, int, int, int, int)'
from 'void (uint16_t *, uint16_t *, uint16_t *, uint16_t *, int, int, int, int, int)'
 2013-02-06 10:21:51 +01:00
Anton Khirnov d9df93efbf mpegvideo: simplify REBASE_PICTURE 
Always evaluate to NULL when the source Picture is not located in the
MpegEncContext.picture array. That will only happen for
next/last_picture_ptr when updating the thread context during h264 frame
threaded decoding, where they will point to elements of ref_list. Since
ref_list is not copied during updating the context and is invalid until
it is constructed for the current slice, there is no point in doing
anything complicated with next/last_picture_ptr, as they will get
updated when the ref_list is filled.

Anton Khirnov f2960097e4 bink: fix a check for the first frame. 
Packet pts is a very unreliable indicator, use
AVCodecContext.frame_number instead.

Anton Khirnov 231fd1ed39 utvideoenc/v410enc: do not set AVFrame.reference. 
That field will be deprecated.
 2013-01-29 07:32:21 +01:00
Anton Khirnov e6b1c3bbe7 pthread: make ff_thread_release_buffer idempotent. 
I.e. don't do anything on already released frames.
 2013-01-29 07:32:10 +01:00
Anton Khirnov 729b37149c mvi: set framerate 
This container does not store timestamps and thus supports CFR only.

Anton Khirnov 098eed95bc mdec: merge mdec_common_init() into decode_init(). 
There is no point in keeping those two functions separate.

Anton Khirnov 940b8b5861 h264: avoid pointless copying of ref lists 
ref_list is constructed from other fields per slice when needed, so do
not copy it for both frame and slice threading.
default_ref_list is constructed per frame and still needs to be copied
to per-slice contexts for slice threading, but a copy is not needed for
frame threading.

Anton Khirnov 90cfc084e3 avpacket: free side data in av_free_packet(). 
Freeing it in av_destruct_packet(), as is done currently, would mean
that we allow it to be allocated with other means. But that would make
av_packet_new_side_data() unsafe.

Side data is not expected to be large, so copying it if required
shouldn't be a problem.
