47e47cfb07 ffplay: fix sws_scale possible out of bounds array access 
As I used simple RGBA formats for subtitles and for the video texture if
avfilter is disabled I kind of assumed that sws_scale won't access data
pointers and strides above index 0, but apparently that is not the case.

Fixes Coverity CID 1396737, 1396738, 1396739, 1396740.

This reverts commit e0c6b32046.

Said commit changed the behavior of the demuxer and decoder in a non
backwards compatible way.
Demuxers should make extradata available at init if possible, and send
new extradata as side data within a packet if needed.

A better fix for the remuxing crash will follow.
