Justin Ruggles ec1f3cab20 avplay: reset decoder flush state when seeking 
Fixes seeking after decoder has already been flushed for codecs using
CODEC_CAP_DELAY.
 2012-02-06 13:22:01 -05:00
Justin Ruggles f1c3d4a68a ape: skip packets with invalid size 2012-02-06 13:22:01 -05:00
Justin Ruggles ac3f8d317c ape: calculate final packet size instead of guessing 
Calculates based on total file size and wavetaillength from the header.
Falls back to multiplying finalframeblocks by 8 instead of 4 so that it will
at least be overestimating for 24-bit. Currently it can underestimate the
final packet size, leading to decoding errors.
 2012-02-06 13:22:01 -05:00
Justin Ruggles c2c316158f ape: stop reading after the last frame has been read 
This avoids buffer overread when the last packet size estimate is too small.
 2012-02-06 13:09:11 -05:00
Justin Ruggles 66f7be3603 ape: return AVERROR_EOF instead of AVERROR(EIO) when demuxing is finished 2012-02-06 13:09:11 -05:00
Justin Ruggles 1bc035bc03 ape: return error if seeking to the current packet fails in ape_read_packet() 2012-02-06 13:09:11 -05:00
Justin Ruggles 6f1a5e8d6b dsputil: remove debug message in dsputil_init(). 
AVCodecContext.bits_per_raw_sample is used for audio too, and values other
than 8, 9, and 10 are valid.
 2012-02-03 16:00:30 -05:00
Justin Ruggles 22c0babbb2 apedec: remove unneeded #include of get_bits.h and associated macro 2012-02-02 21:07:01 -05:00
Justin Ruggles e4169612a1 apedec: av_fast_malloc() instead of av_realloc() 
av_realloc() does not guarantee alignment, which is required for
DSPContext.bswap_buf().
 2012-02-02 21:07:01 -05:00
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
Justin Ruggles c3a06615bd bethsoftvideo: fix palette reading. 
Return the correct number of consumed bytes and set *data_size = 0.
Returned size is 1 too small, leading to that 1 byte being read as the next
frame, which results in an extra blank frame at the beginning of the stream.
 2012-02-01 19:41:39 -05:00
Justin Ruggles 83ce51cc7d mpc7: use av_fast_padded_malloc() 
Avoids doing malloc/free for each frame.
Also fixes valgrind errors due to use of uninitialized padding bytes.

Based on a patch by Reimar Döffinger <Reimar.Doeffinger@gmx.de>
 2012-02-01 19:35:59 -05:00
Justin Ruggles b5b825c381 mpc7: simplify handling of packet sizes that are not a multiple of 4 bytes 2012-02-01 19:35:59 -05:00
Justin Ruggles 236a550c3f Fix a typo in the x86 asm version of ff_vector_clip_int32() 
Specifies the correct number of xmm registers used so that they can be saved
and restored on Win64 if necessary.
 2012-02-01 19:02:32 -05:00
Justin Ruggles 3c432631e9 pcmenc: Do not set avpkt->size. 
It is already the correct size as set by ff_alloc_packet().
 2012-02-01 16:33:27 -05:00
Justin Ruggles 1a670973a7 ff_alloc_packet: modify the size of the packet to match the requested size 
This will simplify encoders which use this function to request the exact
packet size rather than the maximum size.
 2012-02-01 16:33:27 -05:00
Justin Ruggles a3a0691bde adpcmenc: remove some unneeded casts 2012-01-30 19:12:55 -05:00
Justin Ruggles 149f2058a4 adpcmenc: use int16_t and uint8_t instead of short and unsigned char. 2012-01-30 19:12:55 -05:00
Justin Ruggles dd88ae831a adpcmenc: fix adpcm_ms extradata allocation 
Add FF_INPUT_BUFFER_PADDING_SIZE.
If allocation fails, also free memory which was allocated previously in
adpcm_encode_init().
 2012-01-30 19:12:55 -05:00
Justin Ruggles 877a1d409c adpcmenc: return proper AVERROR codes instead of -1 2012-01-30 19:12:55 -05:00
Justin Ruggles cb023d9afe adpcmenc: check for coded_frame allocation failure 2012-01-30 19:12:55 -05:00
Justin Ruggles ddf70db6d7 adpcmenc: Do not set coded_frame->key_frame. 
It is already set in avcodec_alloc_frame().
 2012-01-30 19:12:54 -05:00
Justin Ruggles 3c4add27f7 mpc7: check for allocation failure 2012-01-30 19:11:29 -05:00
Justin Ruggles eac31dd163 mpc7: align local temp buffer 
DSPContext.bswap_buf() requires aligned output
 2012-01-30 19:11:29 -05:00
Justin Ruggles 89eea6df28 aacenc: make sure to encode enough frames to cover all input samples. 
Currently, any samples in the final frame are not decoded because they are
only represented by one frame instead of two. So we encode two final frames to
cover both the analysis delay and the MDCT delay.
 2012-01-30 14:20:24 -05:00
Justin Ruggles f44005b610 aacenc: only use the number of input samples provided by the user. 
Fixes handling of CODEC_CAP_SMALL_LAST_FRAME.
 2012-01-30 14:20:24 -05:00
Justin Ruggles 2c577155a7 libspeexenc: use AVSampleFormat instead of deprecated/removed SampleFormat 
Fixes build with --enable-libspeex
 2012-01-27 11:28:21 -05:00
Justin Ruggles b8dd555c63 aud: remove unneeded field, audio_stream_index from context

This also allows for removal of the private context.
 2012-01-24 14:13:47 -05:00
Justin Ruggles be14a37066 aud: fix time stamp calculation for ADPCM IMA WS 
also allows for removing some unused context fields

Justin Ruggles 10fef6bd6b aud: simplify header parsing 
also allows for removing some unused context fields
 2012-01-24 14:13:47 -05:00
Justin Ruggles 0e6a8b5cf7 aud: set pts_wrap_bits to 64. 
Time stamps are not read from the bitstream, so no wrapping is needed.
 2012-01-24 14:13:47 -05:00
Justin Ruggles 98c290cc08 cosmetics: indentation 2012-01-24 14:13:46 -05:00
Justin Ruggles d481227c54 aud: support Westwood SND1 audio in AUD files. 
Fixes decoding of the handful of "death scream" samples from
"Command and Conquer" that use SND1. e.g.
http://samples.libav.org/game-formats/westwood-aud/nuyell1.aud
http://samples.libav.org/game-formats/westwood-aud/nuyell7.aud
 2012-01-24 14:13:46 -05:00
Justin Ruggles 02e7dbf5ad adpcm_ima_ws: fix stereo decoding 
Stereo ADPCM IMA WS is planar for VQA version 3 and 2-sample interleaved for
VQA version 2.
 2012-01-24 14:13:46 -05:00
Justin Ruggles 220506d23f avcodec: add a new codec_id for CRYO APC IMA ADPCM. 
The stereo layout and extradata is significantly different from that in
Westwood IMA ADPCM, so a separate codec_id is warranted.
 2012-01-24 14:13:41 -05:00

and the actual value can be found in the header.
 2012-01-24 14:08:29 -05:00
Justin Ruggles 9ae846971f vqa: set packet duration. 
Also remove unused context field, audio_frame_counter.

Justin Ruggles 53ed79a260 vqa: use 1/sample_rate as the audio stream time base 2012-01-24 14:08:29 -05:00
Justin Ruggles e1ac69fa27 vqa: set stream start_time to 0. 
The format has no coded timestamps and must use packet durations to generate
them.
 2012-01-24 14:08:29 -05:00
Justin Ruggles e924a4ba71 westwood: split the AUD and VQA demuxers into separate files. 
They have no code in common.
 2012-01-23 10:34:48 -05:00

Justin Ruggles b2c75b6e63 avcodec: Add avcodec_encode_audio2() as replacement for avcodec_encode_audio() 
This allows audio encoders to optionally take an AVFrame as input and write
encoded output to an AVPacket.

This also adds AVCodec.encode2() which will also be usable by video and
subtitle encoders once support is implemented in the public functions.
 2012-01-15 21:24:17 -05:00
Justin Ruggles 5ee5fa021f avcodec: add a public function, avcodec_fill_audio_frame().

 2012-01-13 15:45:30 -05:00
Justin Ruggles 56f22b7e16 pcmenc: set frame_size to 0. 
This indicates that the actual frame size is based on the buf_size passed to
avcodec_encode_audio().
 2012-01-11 09:09:56 -05:00
Justin Ruggles f01f6a8474 gsm demuxer: use generic seeking instead of a gsm-specific function. 
Since packets all contain only a single block, the generic seek function can
be used while still maintaining block-accuracy.
 2012-01-11 08:56:24 -05:00
Justin Ruggles 467879eb54 gsm demuxer: return packets with only 1 gsm block at a time. 
fixes stream copy of raw gsm to mov.
tested with QuickTime.
 2012-01-11 08:56:24 -05:00
Justin Ruggles 82390f57d1 avcodec: add GSM parser 
The WAVE demuxer returns packets with many blocks per frame, which needs to be
parsed into single blocks. This has a side-effect of fixing the timestamps.
 2012-01-11 08:56:24 -05:00
Justin Ruggles 4556ebfb7d ipmovie: fix pts for CODEC_ID_INTERPLAY_DPCM

Justin Ruggles 77c5b66cbe g722enc: set frame_size, and also handle an odd number of input samples 
The fate reference is updated because the previous test skipped a sample in
each encode() call due each input frame having an odd number of samples.
 2012-01-07 13:38:23 -05:00

Justin Ruggles e49d21306a alacdec: implement the 2-pass prediction type. 
The reference encoder does not generate any streams using this, but the
reference decoder can handle it, so we should as well.
 2012-01-03 13:15:24 -05:00
Justin Ruggles bb63475aec alacenc: implement the 2-pass prediction type. 
This isn't used by the reference encoder, but it is supported by the decoder.
