Possibly improve readability.

Avoid confusing and pointless double assignment of variable
resampled_data_size.

swr_free() already checks for nullness, no need to add the check in
calling code.

The comment now references swr_convert(), rather than audio_convert(),
which was deprecated and/or dropped.

Favor av_buffersrc_add_ref() instead, which is more powerful.

Will help factorization with the pending -af patch, and add some checks
missing in the original code.

It was deprecated since a long time and removed after the 2->3 major
bump.

Deprecate functions:
avfilter_fill_frame_from_buffer_ref
avfilter_fill_frame_from_audio_buffer_ref
avfilter_fill_frame_from_video_buffer_ref

and schedule to drop them at the next API major bump.

The function avfilter_copy_buf_props() should be used instead.

Fix warning:
ffplay.c:1578:40: warning: passing argument 5 of ‘avfilter_graph_create_filter’ discards ‘const’ qualifier from pointer target type [enabled by default]
libavfilter/avfiltergraph.h:84:5: note: expected ‘void *’ but argument is of type ‘const enum PixelFormat *’

This fixes: ffplay -f lavfi -i cellauto
This was a regression since factorizing the filter code with ffmpeg.
