Justin Ruggles 0759c8eb10 apedec: fix handling of packet sizes that are not a multiple of 4 bytes 2012-02-02 21:07:01 -05:00
Diego Biurrun aaf47bcde7 Drop ALT_ prefix from BITSTREAM_READER_LE name.
The prefix is a historic remnant that probably meant "alternative".
Now that the A32 bitstream reader has been dropped it makes no sense anymore.

Justin Ruggles 0eea212943 Add avcodec_decode_audio4().
Deprecate avcodec_decode_audio3().
Implement audio support in avcodec_default_get_buffer().
Implement the new audio decoder API in all audio decoders.

Mans Rullgard 644bff6c9b apedec: fix signed integer overflows
This bit manipulation is equivalent but avoids undefined
shifts and overflows.

Justin Ruggles c298b2b8db apedec: consume the whole packet when copying to the decoder buffer.
This avoids artifically consuming a partial packet but ignoring remaining data
in subsequent calls.

Justin Ruggles de157f2118 apedec: do not needlessly copy s->samples to nblocks.
also move nblocks to the local scope where it is used.

Justin Ruggles 4315c7d35a apedec: check output buffer size after calculating actual output size 2011-11-10 10:25:47 -05:00
Justin Ruggles ad17207b51 apedec: remove unneeded entropy decoder normalization.
The decoder already skips data at the end of the packet without this.
Also remove 2 APEContext fields that were only used for the end-of-frame
normalization.

Justin Ruggles 9a33264478 apedec: assert that s->samples is not negative before trying to decode 2011-10-28 11:47:29 -04:00
Justin Ruggles 0927154d37 apedec: use FFALIGN macro for internal data buffer size 2011-10-28 11:47:28 -04:00
Justin Ruggles 5b8009f4c8 apedec: do not keep incrementing the input data pointer past the end of the
buffer during entropy decoding.

The pointer address could overflow, which would likely segfault. Instead set
the context error flag to indicate that the decoder tried to read past the
end of the packet data.

Justin Ruggles a4c32c9a63 apedec: check for input buffer overflow while reading frame header 2011-10-28 11:47:28 -04:00
Justin Ruggles fd244ae3a0 apedec: use unsigned int for offset
avoids implementation-defined unsigned-to-signed conversion and simplifies
the bounds checking.
2011-10-28 11:47:28 -04:00
Justin Ruggles 89ec474a43 apedec: remove pointless increment of 'buf'
The variable is not used anymore at that point.

Justin Ruggles 52d4fb2a3d apedec: set s->currentframeblocks after validating nblocks 2011-10-28 11:47:28 -04:00
Justin Ruggles 2cab578489 apedec: use unsigned int for 'nblocks' and make sure that it's within int range 2011-10-28 11:47:27 -04:00
Justin Ruggles b7e5145759 apedec: do not set s->samples until after validation.
This prevents errors and/or invalid writes in the next decode call due to
s->samples still being negative.

Justin Ruggles 3c25209bd9 apedec: remove unneeded check for zero-size packet.
This is already checked by avcodec_decode_audio3().

Anton Khirnov ec6402b7c5 lavc: use designated initialisers for all codecs.
It's more readable and less prone to breakage.

Reinhard Tartler 21a19b7912 doxygen: Prefer member groups over grouping into modules
Before this, almost all module groups have been used for grouping functions
and fields in structures semantically. This causes them to not appear
properly in the file documentation and needlessly clutters up the "Modules"
index.

Additionally, this commit streamlines some spelling and appearances.

Reinhard Tartler 737eb5976f Merge libavcore into libavutil
It is pretty hopeless that other considerable projects will adopt
libavutil alone in other projects. Projects that need small footprint
are better off with more specialized libraries such as gnulib or rather
just copy the necessary parts that they need. With this in mind, nobody
is helped by having libavutil and libavcore split. In order to ease
maintenance inside and around FFmpeg and to reduce confusion where to
put common code, avcore's functionality is merged (back) to avutil.

Thilo Borgmann 7a00bbad21 Implement avcodec_decode_video2(), _audio3() and _subtitle2() which takes an
AVPacket argument rather than a const uint8_t *buf + int buf_size. This allows
passing of packet-specific flags from demuxer to decoder, such as the keyframe
flag, which appears necessary to playback corePNG P-frames.

Patch by Thilo Borgmann thilo.borgmann googlemail com, see also the thread
"Google Summer of Code participation" on the mailinglist.

Luca Abeni dd1c8f3e6e Bump Major version, this commit is almost just renaming bits_per_sample to
bits_per_coded_sample but that cannot be done seperately.
Patch by Luca Abeni
Also reset the minor version and fix the forgotton change to libfaad.
Note: The API/ABI should not be considered stable yet, there still may
be a change done here or there if some developer has some cleanup ideas and
patches!
