## 0.8.0

- Supports FFmpeg 5.0

## 0.7.1

- `impl Send` for binding types.

- Dependencies version bump

## 0.7.0

- Better docs and tests (`transcoding`, `avio_writing`, `thumbnail`), more bug fixes.

- Add `av_rescale_q`, `av_rescale_q_rnd` and `ra` for easier `AVRational` manipulation.

- Add `AVFrame::make_writable`, `AVFrame::is_writable` for frame writable checking.

- Split `SwrContext::convert` into `convert` and `convert_raw` for more flexible audio api.

- Export `UnsafeDerefMut` for users to access raw FFmpeg structure with an unsafe context.

- Allow `AVFilterGraph::parse_ptr` accept no filter inputs or outputs.

- Impl `Send` for `AVPacket` and `AVFrame`, which makes video packet processing across thread boundary possible.

## 0.6.0

- Better docs and tests (rewrites the `transcoding` and `transcoding_aac` tests), more bug fixes.

- Add `channel_layout` getter for `AVCodecContext`.

- Sync implementation between `AVImage` and `AVSamples` since they share many things in common.

- Rename `AVCodecContext::set_codecpar` to `AVCodecContext::apply_codecpar`, because this function doesn't set a field named as `codecpar` in `AVCodecContext`, but extracts the given codec parameters and set several fields of `AVCodecContext`.

- Rename `AVFrameWithImageBuffer` to `AVFrameWithImage`. And it's implementation was rewritten which aims at binding more information with it. Not it's more ergonomic.

- Wrap `av_malloc` and `av_free` in `AVMem`.
