| 145 | 145 | Add avfilter_fill_frame_from_{audio_,}buffer_ref() functions. |

| 148 | +lavd 54.0.0, lavfi 3.5.0 |
| 149 | + xxxxxxx, xxxxxxx - add a new API for reference counted buffers and buffer |
| 150 | + pools (new header libavutil/buffer.h). |
| 151 | + xxxxxxx - add AVPacket.buf to allow reference counting for the AVPacket data. |
| 152 | + Add av_packet_from_data() function for constructing packets from |
| 153 | + av_malloc()ed data. |
| 154 | + xxxxxxx - move AVFrame from lavc to lavu (new header libavutil/frame.h), add |
| 155 | + AVFrame.buf/extended_buf to allow reference counting for the AVFrame |
| 156 | + data. Add new API for working with reference-counted AVFrames. |
| 157 | + xxxxxxx - add the refcounted_frames field to AVCodecContext to make audio and |
| 158 | + video decoders return reference-counted frames. Add get_buffer2() |
| 159 | + callback to AVCodecContext which allocates reference-counted frames. |
| 160 | + Add avcodec_default_get_buffer2() as the default get_buffer2() |
| 161 | + implementation. |

| 163 | + reget_buffer(), avcodec_default_get_buffer(), |
| 164 | + avcodec_default_reget_buffer(), avcodec_default_release_buffer(). |
| 165 | + Remove avcodec_default_free_buffers(), which should not have ever |
| 166 | + been called from outside of lavc. |
| 167 | + Deprecate the following AVFrame fields: |
| 168 | + * base -- is now stored in AVBufferRef |
| 169 | + * reference, type, buffer_hints -- are unnecessary in the new API |
| 170 | + * hwaccel_picture_private, owner, thread_opaque -- should not |

| 174 | + which are not exported anymore. |
| 175 | + xxxxxxx - switch libavfilter to use AVFrame instead of AVFilterBufferRef. Add |
| 176 | + av_buffersrc_add_frame(), deprecate av_buffersrc_buffer(). |
| 177 | + Add av_buffersink_get_frame() and av_buffersink_get_samples(), |
