- Update version to 7.0.1:
+ Major:
* Drop support for FFmpeg < 4.0. (:issue:`559`)
* Introduce per-error exceptions, and mirror the builtin exception heirarchy. It is recommended to examine your error handling code, as common FFmpeg errors will result in ValueError baseclasses now. (:issue:`563`)
* Data stream's encode and decode return empty lists instead of none allowing common API use patterns with data streams.
* Remove whence parameter from :meth:`InputContainer.seek` as non-time seeking doesn't seem to actually be supported by any FFmpeg formats.
+ Minor:
* Users can disable the logging system to avoid lockups in sub-interpreters. (:issue:`545`)
* Filters support audio in general, and a new :meth:`.Graph.add_abuffer`. (:issue:`562`)
* :func:`av.open` supports timeout parameters. (:issue:`480` and :issue:`316`)
* Expose :attr:`Stream.base_rate` and :attr:`Stream.guessed_rate`. (:issue:`564`)
* :meth:`.VideoFrame.reformat` can specify interpolation.
* Expose many sets of flags.
+ Fixes:
* Removed deprecated AV_FRAME_DATA_QP_TABLE_* enums. (:issue:`607`)
* Fix typing in :meth:`.CodecContext.parse` and make it more robust.
* Fix wrong attribute in ByteSource. (:issue:`340`)
* Remove exception that would break audio remuxing. (:issue:`537`)
* Log messages include last FFmpeg error log in more helpful way.
* Use AVCodecParameters so FFmpeg doesn't complain. (:issue:`222`)
