Justin Ruggles 7e6593e977 alac: eliminate 2 unneeded local variables in bastardized_rice_decompress() 
x_modified is just unnecessary, and final_val can be removed by simplifying
the unsigned-to-signed conversion.

Nicolas George 0fe8acf2d6 ffmpeg: add -(no)stdin option. 
Allows to disable interaction from standard input.
Useful, for example, if ffmpeg is in the background process group.
Roughly the same result can be achieved with "ffmpeg ... < /dev/null"
but it requires a shell.

where an MPEG2 IDCT is expected or vice versa.

Kostya Shishkov 4cfb0d871d tscc2: do not add/subtract 128 bias during DCT 
It turns out that the reference decoder subtracts 128 from DC during block
decode but adds it back during reordering block with zigzag pattern.
Transforming block with incorrect DC caused heavy visual artifacts for
many quantisers.
