ffmpeg: add per-stream input option drop_changed

Browse Source 
This is a replacement in ffmpeg for the deprecated avcodec flag AV_CODEC_FLAG_DROPCHANGED.

This option is meant to be used when the filtergraph should not be
reinited upon input parameter changes as that leads to loss of state
in the filtergraph potentially leading to broken or aborted output,
e.g. inserting of silence with first_pts specified in aresample.

Generally useful to avoid corrupted yet decodable packets in live
streaming inputs.

This option when enabled takes precedence over reinit_filters
