Stefano Sabatini fbb8468f20 ffprobe: prefer lowercase section names over uppercase ones 
This is consistent with chapter names. The default writer section names
are converted to uppercase for keeping backward compatibility.

Mans Rullgard 1703013cb7 avidec: fix signed overflow in avi_sync() 
Keeping byte values read from the file as unsigned is consistent
with how they are subsequently used and avoids an undefined left
shift by 24 when bit 7 is set.

Reimar Döffinger 4b4a6ebd68 Support playing SMV files. 
Audio and video are interleaved via stream cur_dts - no idea how
reliable this is.
It also cannot display the video properly - it is stored with
about 15 in a single JPEG frame, I cannot think of a reasonable
way to implement this.
