asf: update seek test reference
This updates the seek test reference to match de11ee9. Before thischange, most of the seeks requested positions before the supposedstart of the file (the preroll time), resulting in the first packetbeing returned. With the preroll subtracted, some of these seeks...

aaccoder: Change FFMAX for allzero flag to OR bit operation
Signed-off-by: Ronald S. Bultje <firstname.lastname@example.org>
avio: rename put_flush_packet -> avio_flush
avio: deprecate url_close_buf
It's not used anywhere and its return value looks broken.
avio: deprecate url_open_buf
It's only used in one place and does the same thing asavio_alloc_context.
avio: always compile avio_printf, rather than on CONFIG_MUXERS
avio: avio_ prefix for url_fprintf
avio: change avio_tell/skip from macros to inline functions
avio: make url_setbufsize internal.
lavf: move ff_get_v from avio.h to avio_internal.h
And rename it to ffio_read_varlen.
nutenc: mux chapters.
doc: update applehttp documentation
Integrate more comments from Stefano.
lavf: replace avio_seek(SEEK_CUR) with avio_skip where it makes sense
Remove occurrences of my old email address
dsputil: add bswap16_buf()
There are several places where a buffer is byte-swapped in 16-bit units.This allows them to share code which can be optimised for variousarchitectures.
darwin: use -read_only_relocs flag only on 32-bit x86
Avoids the linker warning:ld: warning: -read_only_relocs cannot be used with x86_64
replace FFmpeg with Libav in doc/
unless it stands for ffmpeg the program or is historic
use LIBAV_LICENSE and LIBAV_VERSION instead of FFMPEG_*
replace FFMPEG with LIBAV in FFMPEG_CONFIGURATION
also update the multiple inclusion guards in config.h|mak
partially rename FFmpeg to Libav
update mailing list references and irc channels in configure
mp3enc: remove mp3_write_packet(), use ff_raw_write_packet() instead
The two functions are identical, no point in duplicating code here.
Do not attempt to decode APE file with no frames
This fixes invalid reads/writes with this sample:http://packetstorm.linuxsecurity.com/1103-exploits/vlc105-dos.txt
jvdec: don't use deprecated url_feof()
mathops: fix MULL when the compiler does not inline the function.
If the function is not inlined, an immmediate cannot be used for theshift parameter, so the %cl register must be used instead in that case.
This fixes compilation for x86-32 using gcc with --disable-optimizations.
id3v2: merge TYER/TDAT/TIME to date tag
mathops: change "g" constraint to "rm" in x86-32 version of MUL64.
The 1-arg imul instruction cannot take an immediate argument, only a registeror memory argument.
mathops: convert MULL/MULH/MUL64 to inline functions rather than macros.
This fixes unexpected name collisions that were occurring with variablesdeclared within the macros.It also fixes the fate-acodec-ac3_fixed regression test on x86-32.
Use AVERROR_EXIT with url_interrupt_cb.
Functions interrupted by url_interrupt_cb should not be restarted.Therefore using AVERROR was wrong, as it did not allow to distinguishwhen the underlying system call was interrupted and actually needed to be...
This is different from AVERROR because calls that fail with EINTRshould usually be restarted.

AVIOContext.error should be used directly instead.

This file is a bad idea and also badly outdated.
ac3enc: add SIMD-optimized shifting functions for use with the fixed-point AC3 encoder.
ac3enc: do not right-shift fixed-point coefficients in the final MDCT stage.
This increases the accuracy of coefficients, leading to improved quality.Rescaling of the coefficients to full 25-bit accuracy is done rather thanoffsetting the exponent values. This requires coefficient scaling to be done...
mm decoder: move buffer allocation from decode_init() to decode_frame()
This permits playback in ffplay when libavfilter is enabled.
jv demuxer: prevent video packet size overflow
In the event of overflow, the JV_PADDING state will avio_skip overany overflow bytes (using JVFrame.total_size).
jv demuxer: define JV_PREAMBLE_SIZE instead of hard coding the number
jv demuxer: calculate palette_size for each frame in read_header

VP8: fix other function declaration

VC1: Export profile/level
ffmpeg: remove unused variable in ffmpeg_exit()
Fix the warning:ffmpeg.c: In function ‘ffmpeg_exit’:ffmpeg.c:509: warning: unused variable ‘j’
VP8: optimize VP8Context struct ordering
Shaves at least 3KB off code size on x86, should improve cache utilization.This would probably be useful to do for other decoders/encoders as well.
VP8: fix function declaration
VP8: token probs doesn't need padding
prob0 is the only prob array ever accessed, so prob1 can serve as paddingfor prob0.
VP8: use a goto to break out of two loops
A break statement was supposed to break out of two loops, but only broke out of one.Didn't affect output, just could have been marginally slower.

aacenc: Fix a segfault in search_for_quantizers

avio: deprecate url_feof
AVIOContext.eof_reached should be used directly instead.
mpegts: add all stream languages into metadata
This is used at least on some older DVB broadcasts for dual-mono audiotracks.
In retry_transfer_wrapper, do not check url_interrupt_cb, causes problemswhen writing and pressing q during encoding. Instead, check url_interrupt_cbat the end.
Note that when a protocol is interrupted by url_interrupt_cb, some data maybe silently discarded: the protocol context is not suitable for anything...

avio: deprecate url_fget_max_packet_size
AVIOContext.max_packet_size should be used directly instead.
aacenc: remove the data arrays
lavf: document the use of multiple entries in language metadata tag
aac_latm_dec: use aac context and aac m4ac
When decoding latm config, use the corresponding aac context and itsm4ac instead of using NULL and a local variable. This fixes decoding ofaudio in MPEG TS from SBTVD (the Brazillian Digital TV Sytem), whenthere is no extradata. This is the case when using the decoder with...
