| 14 | 14 | API changes, most recent first: |
| 15 | 15 | |
| 16 | +2013-03-xx - Reference counted buffers - lavu 52.8.0, lavc 55.0.0, lavf 55.0.0, |
| 17 | +lavd 54.0.0, lavfi 3.5.0 |
| 18 | + xxxxxxx, xxxxxxx - add a new API for reference counted buffers and buffer |
| 19 | + pools (new header libavutil/buffer.h). |
| 20 | + xxxxxxx - add AVPacket.buf to allow reference counting for the AVPacket data. |
| 21 | + Add av_packet_from_data() function for constructing packets from |
| 22 | + av_malloc()ed data. |
| 23 | + xxxxxxx - move AVFrame from lavc to lavu (new header libavutil/frame.h), add |
| 24 | + AVFrame.buf/extended_buf to allow reference counting for the AVFrame |
| 25 | + data. Add new API for working with reference-counted AVFrames. |
| 26 | + xxxxxxx - add the refcounted_frames field to AVCodecContext to make audio and |
| 27 | + video decoders return reference-counted frames. Add get_buffer2() |
| 28 | + callback to AVCodecContext which allocates reference-counted frames. |
| 29 | + Add avcodec_default_get_buffer2() as the default get_buffer2() |
| 30 | + implementation. |
| 31 | + Deprecate AVCodecContext.get_buffer() / release_buffer() / |
| 32 | + reget_buffer(), avcodec_default_get_buffer(), |
| 33 | + avcodec_default_reget_buffer(), avcodec_default_release_buffer(). |
| 34 | + Remove avcodec_default_free_buffers(), which should not have ever |
| 35 | + been called from outside of lavc. |
| 36 | + Deprecate the following AVFrame fields: |
| 37 | + * base -- is now stored in AVBufferRef |
| 38 | + * reference, type, buffer_hints -- are unnecessary in the new API |
| 39 | + * hwaccel_picture_private, owner, thread_opaque -- should not |
| 40 | + have been acessed from outside of lavc |
| 41 | + * qscale_table, qstride, qscale_type, mbskip_table, motion_val, |
| 42 | + mb_type, dct_coeff, ref_index -- mpegvideo-specific tables, |
| 43 | + which are not exported anymore. |
| 44 | + xxxxxxx - switch libavfilter to use AVFrame instead of AVFilterBufferRef. Add |
| 45 | + av_buffersrc_add_frame(), deprecate av_buffersrc_buffer(). |
| 46 | + Add av_buffersink_get_frame() and av_buffersink_get_samples(), |
| 47 | + deprecate av_buffersink_read() and av_buffersink_read_samples(). |
| 48 | + Deprecate AVFilterBufferRef and all functions for working with it. |
| 49 | + |
| 16 | 50 | 2013-xx-xx - xxxxxxx - lavu 52.8.0 - avstring.h |
| 17 | 51 | Add av_isdigit, av_isgraph, av_isspace, av_isxdigit. |
