* check for coded_frame allocation failure in several audio encodersJustin Ruggles2012-02-25
|
* audio encoders: do not set coded_frame->key_frame.Justin Ruggles2012-02-25
| | | | it is already set in avcodec_alloc_frame()
* pcmenc: Do not set avpkt->size.Justin Ruggles2012-02-01
| | | | It is already the correct size as set by ff_alloc_packet().
* pcmenc: use AVCodec.encode2()Justin Ruggles2012-01-15
|
* avcodec: Add avcodec_encode_audio2() as replacement for avcodec_encode_audio()Justin Ruggles2012-01-15
| | | | | | | | 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.
* pcmenc: set frame_size to 0.Justin Ruggles2012-01-11
| | | | | This indicates that the actual frame size is based on the buf_size passed to avcodec_encode_audio().
* Add avcodec_decode_audio4().Justin Ruggles2011-12-02
| | | | | | Deprecate avcodec_decode_audio3(). Implement audio support in avcodec_default_get_buffer(). Implement the new audio decoder API in all audio decoders.
* pcmdec: remove unneeded resetting of samples pointerJustin Ruggles2011-11-23
|
* pcmdec: fix output buffer size check by calculating the actual output sizeJustin Ruggles2011-10-26
| | | | prior to decoding.
* pcmdec: move codec-specific variable declarations to the corresponding codecJustin Ruggles2011-10-26
| | | | blocks.
* pcmdec: return buf_size instead of src-buf.Justin Ruggles2011-10-26
| | | | | The values will always be the same, so this change eliminates an unneeded variable. It also gets rid of the need to reset src when memcpy() is used.
* avcodec: remove the Zork PCM encoder.Justin Ruggles2011-10-26
| | | | | | The Zork PCM decoder does not decode the 1 sample we have correctly, therefore the encoder based on the decoder is also incorrect. There is no good reason to keep the encoder.
* pcm_zork: use AV_SAMPLE_FMT_U8 instead of shifting all samples by 8.Justin Ruggles2011-10-26
|
* pcmenc: remove unneeded sample_fmt check.Justin Ruggles2011-10-26
| | | | It is already checked by avcodec_open2().
* pcmdec: move number of channels check to pcm_decode_init()Justin Ruggles2011-10-26
|
* pcmdec: remove unnecessary check for sample_fmt changeJustin Ruggles2011-10-26
|
* pcmdec: move DVD PCM bits_per_coded_sample check near to the code that setsJustin Ruggles2011-10-26
| | | | the sample size.
* pcmdec: do not needlessly set *data_size to 0Justin Ruggles2011-10-26
|
* pcm: reduce pointer type castingMans Rullgard2011-10-13
| | | | | | | | | Making 'samples' a pointer to uint8_t simplifies the DECODE macro and reduces the amount of type casting overall. This also fixes some signed overflows on left shift. Signed-off-by: Mans Rullgard <mans@mansr.com>
* Remove statements immediately following unconditional jumpsMans Rullgard2011-07-03
| | | | | | This removes a number of compiler warnings. Signed-off-by: Mans Rullgard <mans@mansr.com>
* pcm: Add const to cast in ENCODE macro.Diego Biurrun2011-04-19
| | | | | This fixes a lot of warnings of the sort: libavcodec/pcm.c:105: warning: cast discards qualifiers from pointer target type
* Replace FFmpeg with Libav in licence headersMans Rullgard2011-03-19
| | | | Signed-off-by: Mans Rullgard <mans@mansr.com>
* Remove final semicolon from some macrosMans Rullgard2011-02-10
| | | | | | This avoids double semicolons after macro expansion. Signed-off-by: Mans Rullgard <mans@mansr.com>
* Add ff_ prefix to data symbols of encoders, decoders, hwaccel, parsers, bsf.Diego Elio Pettenò2011-01-26
| | | | | | | None of these symbols should be accessed directly, so declare them as hidden. Signed-off-by: Mans Rullgard <mans@mansr.com>
* Don't declare a pcm_dvd encoder.Diego Elio Pettenò2011-01-25
| | | | | | | | | | The PCM_DVD encoder would be left unused, as allcodecs.c properly declared it as being decoder-only, but it would still be built into the object file. Since there is no block of code to properly encode this PCM format, it's not a full codec. Signed-off-by: Mans Rullgard <mans@mansr.com>

| | | | | | | | Passing an explicit filename to this command is only necessary if the documentation in the @file block refers to a file different from the one the block resides in. Originally committed as revision 22921 to svn://svn.ffmpeg.org/ffmpeg/trunk

| | | | | | | | | | | 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.
