Stefano SabatiniandAnton Khirnov 8a4a5f6ff7 lavc: add format field to AVFrame
The format is a per-frame property, having it in AVFrame simplify the
operation of extraction of that information, since avoids the need to
access the codec/stream context.

Stefano SabatiniandAnton Khirnov 3a2ddf7c2c lavc: add width and height fields to AVFrame
width and height are per-frame properties, setting these values in
AVFrame simplify the operation of extraction of that information,
since avoids the need to check the codec/stream context.

Stefano SabatiniandAnton Khirnov b58dbb5b03 lavc: add a sample_aspect_ratio field to AVFrame
The sample aspect ratio is a per-frame property, so it makes sense to
define it in AVFrame rather than in the codec/stream context.
Simplify application-level sample aspect ratio information extraction,
and allow further simplifications.
