5.0.0
-----
- Introduce conditional compilation flags to preserve functions that are
removed from ffmpeg 5.0 and onwards.
- Fix examples so they are using the ffmpeg-sanctionned way of doing
things. More specifically, AVStream.codec has been removed, and the
correct way of getting the codec from a stream is to use
Context::from_parameters(stream.parameters()) and then that context's
encoder / decoder.
4.4.0
-----
- crate: `ffmpeg43` feature flag (noop since 4.3.4) has been dropped from default features.
- codec: deprecate APIs based on deprecated (since FFmpeg 3.1) `avcodec_decode_video2()` / `avcodec_decode_audio4()` / `avcodec_encode_video2()` /`avcodec_encode_audio2()` -- `decoder::Video::decode()`, `decode::Audio::decode()`, `encoder::Video::encode()` and `encoder::Audio::decode()`. Users should migrate to `send_packet()` / `send_eof()`, `receive_frame()`, `send_frame()` / `send_eof()`, and `receive_packet()` APIs instead, which are based on the modern send/receive APIs. See [documentation in `libavcodec/avcodec.h`](https://github.com/FFmpeg/FFmpeg/blob/n4.3.1/libavcodec/avcodec.h#L84-L196) for details. (#28)
- codec: fix signature of `Packet::write_interleaved`; previously `Result<bool, Error>`, now `Result<(), Error>`. (#25)
4.3.8
-----
- software::resampling: add Context::get_with for specifying additional options. (#41)
4.3.7
-----
- codec: fix codec description potential null ptr issue. (#36)
4.3.6
-----
- util: fix Windows compatibility due to unavailable errnos. (#30)
4.3.5
-----
- util: add `util::log` module to expose FFmpeg's logging facilities.
- filter: add method `Source::close()` to expose `av_buffersrc_close`. (#23)
- codec: add new encoding/decoding APIs `send_frame()` / `send_eof()`, `receive_packet()` to `encoder::{Audio, Video}` and `send_packet()` / `send_eof()`, `receive_frame()` to `decoder::{Audio, Video}` based on modern send/receive APIs (instead of `avcodec_decode_video2()` / `avcodec_decode_audio4()` / `avcodec_encode_video2()` /`avcodec_encode_audio2()` which have been deprecated since FFmpeg 3.1). Users should consider switching to the new APIs. See [documentation in `libavcodec/avcodec.h`](https://github.com/FFmpeg/FFmpeg/blob/n4.3.1/libavcodec/avcodec.h#L84-L196) for details. (#28)
- util: introduce new `Error` variant `Error::Other { errno }` for wrapped POSIX error codes (see the `AVERROR` macro in `libavutil/error.h`), and reexport common POSIX error codes under `util::error`. (#24)
4.3.4
-----
- crate: FFmpeg version detection is now automatic, obseleting feature flags `ffmpeg4`, `ffmpeg41`, `ffmpeg42` and `ffmpeg43`. The flags are kept as noop for now, will be removed in 5.0.
