* lavc: handle hw_frames_ctx where necessaryAndrey Turkin2016-05-25
| | | | | | | avcodec_copy_context() didn't handle hw_frames_ctx references correctly which could cause crashes. Signed-off-by: Anton Khirnov <anton@khirnov.net>
* lavc: deprecate avcodec_get_context_defaults3()Anton Khirnov2016-05-23
| | | | | | | | | This function is supposed to "reset" a codec context to a clean state so that it can be opened again. The only reason it exists is to allow using AVStream.codec as a decoding context (after it was already opened/used/closed by avformat_find_stream_info()). Since that behaviour is now deprecated, there is no reason for this function to exist anymore.
* lavc: deprecate avcodec_copy_context()Anton Khirnov2016-05-23
| | | | | | | | | Since AVCodecContext contains a lot of complex state, copying a codec context is not a well-defined operation. The purpose for which it is typically used (which is well-defined) is copying the stream parameters from one codec context to another. That is now possible with through the AVCodecParameters API. Therefore, there is no reason for avcodec_copy_context() to exist.

* lavc: deprecate the use of AVCodecContext.time_base for decodingAnton Khirnov2014-10-15
| | | | | | | | | | | When decoding, this field holds the inverse of the framerate that can be written in the headers for some codecs. Using a field called 'time_base' for this is very misleading, as there are no timestamps associated with it. Furthermore, this field is used for a very different purpose during encoding. Add a new field, called 'framerate', to replace the use of time_base for decoding.

* lavc: add avcodec_free_context().Anton Khirnov2014-05-18
| | | | | | | | | | | Right now, the caller has to manually manage some allocated AVCodecContext fields, like extradata or subtitle_header. This is fragile and prone to leaks, especially if we want to add more such fields in the future. The only reason for this behaviour is so that the AVStream codec context can be reused for decoding. Such reuse is discouraged anyway, so this commit is the first step to deprecating it.
* lavc: properly handle subtitle_header in avcodec_copy_context()Anton Khirnov2014-05-15
|
* lavc: preserve the original private data in avcodec_copy_context()Anton Khirnov2014-05-15
| | | | | If a non-NULL codec was passed to avcodec_alloc_context3(), private data will be already allocated in dest.
* pthread: store thread contexts in AVCodecInternal instead of AVCodecContextAnton Khirnov2013-11-04
| | | | | | It's a private field, it should not be visible to callers. Deprecate AVCodecContext.thread_opaque
* Give less generic names to global library option arraysDiego Biurrun2013-08-02

* Move AVFormatContext/AVCodecContext option tables to separate files.Anton Khirnov2012-03-20
| | | | This will allow us to automatically generate manpages for them.
* lavc: deprecate AVCodecContext.sub_id.Anton Khirnov2012-03-04
| | | | | | | In most places where it's used, it's as a pointless write-only field. Only rv10 decoder actually reads from it, but it stores some internal version info in it. There is no reason for it to be in a public field.
* libvorbis: fix use of minrate/maxrate AVOptionsJustin Ruggles2012-02-29
| | | | | | - enable the options for audio encoding - properly check for user-set maxrate - use correct calling order in vorbis_encode_setup_managed()
* mpegvideo_enc: add quantizer_noise_shaping private option.Anton Khirnov2012-02-29
| | | | Deprecate corresponding AVCodecContext field.
* lavc: deprecate AVCodecContext.inter_threshold.Anton Khirnov2012-02-29
| | | | It's unused.
* lavc: deprecate AVCodecContext.color_table_id.Anton Khirnov2012-02-29
| | | | | It's currently only used as temporary storage by the mov demuxer. Make it use a local variable instead.
* mpegvideo_enc: add chroma/luma_elim_threshold private options.Anton Khirnov2012-02-29
| | | | Deprecate corresponding AVCodecContext fields.
* mpegvideo_enc: add cbp_rd flag to mpv_flags.Anton Khirnov2012-02-29
| | | | Deprecate CODEC_FLAG_CBP_RD.
* mpegvideo_enc: add qp_rd flag to mpv_flags.Anton Khirnov2012-02-29
| | | | Deprecate CODEC_FLAG_QP_RD.
* mpegvideo_enc: add strict_gop flag to mpv_flags.Anton Khirnov2012-02-29
| | | | Deprecate CODEC_FLAG2_STRICT_GOP.
* lavc: add -mpv_flags to mpegvideo_enc-based encoders.Anton Khirnov2012-02-29
| | | | | Deprecate CODEC_FLAG2_SKIP_RD in favor of the corresponding mpv_flags flag.
* Move PS2 MMI code below the mips subdirectory, where it belongs.Diego Biurrun2012-02-13
| | | | | Also give a more suitable name to the MMI-optimized IDCT; it is not PS2-specific, as the name currently suggests.
* Remove Sun medialib glue code.Diego Biurrun2012-02-08
| | | | | It is obscure, most likely unused and not bit-exact compared to libavcodec due to a different IDCT transform algorithm.
* lavc: set AVCodecContext.codec in avcodec_get_context_defaults3().Anton Khirnov2012-01-31
| | | | | | | | | This way, if the AVCodecContext is allocated for a specific codec, the caller doesn't need to store this codec separately and then pass it again to avcodec_open2(). It also allows to set codec private options using av_opt_set_* before opening the codec.
* lavc: add avcodec_is_open().Anton Khirnov2012-01-31
| | | | | | | It allows to check whether an AVCodecContext is open in a documented way. Right now the undocumented way this check is done in lavf/lavc is by checking whether AVCodecContext.codec is NULL. However it's desirable to be able to set AVCodecContext.codec before avcodec_open2().

* threads: change the default for threads back to 1Janne Grunau2012-01-21
| | | | | | Using threaded decoding by default breaks backward compatibility if AVHWAccel is used or if an appliction sets threadunsafe callbacks. Avconv and avplay still use -threads auto if not specified.

* mpegenc: use avctx->slices as number of slicesJanne Grunau2012-01-02
| | | | | | Adds a new member to MpegEncContext to hold the number of used slice contexts. Fixes segfaults with '-threads 17 -thread_type slice' and fate-vsynth{1,2}-mpeg{2,4}thread{,_ilace} with --disable-pthreads.
* threads: default to automatic thread count detectionJanne Grunau2011-12-31

* options: set minimum for "threads" to zeroJanne Grunau2011-12-22
| | | | | A negative number of threads does not make sense and 0 is used for autodetection. Adds a symbolic name for autodetection.
* avcodec: move some AVCodecContext fields to an internal struct.Justin Ruggles2011-11-19
| | | | | | | | A new field, AVCodecContext.internal is used to hold a new struct AVCodecInternal, which has private fields that are not codec-specific and are used by general libavcodec functions. Moved internal_buffer, internal_buffer_count, and is_copy.
