[x265] Passing multiple images to x265 CLI

[Mario Rohkrämer]

The current x265 CLI expects exactly one input file name. There is no  
logic coded to handle a sequence of input files to be processed. You will  
have to execute the encoder for one input file, wait for it to finish, and  
then start a new instance if there is more input to be encoded to a  
separate output file.

By the way, x265 does not support TIFF images as input, anyway: Only raw  
YUV video streams (with or without YUV4MPEG header).

To process a sequence of TIFF images as a video, you better use ffmpeg,  
which is able to read an image sequence named with a pattern you can  
describe with sprintf format strings. Also you would have to define the  
target frame rate explicitly as parameter for ffmpeg.

Alternatively, you would need to find a tool which can convert a sequence  
of TIFF images to a raw YUV stream with YUV4MPEG header if you prefer a  
separate x265 encoder (e.g. ffmpeg can output the format "-f yuv4mpegpipe"  
and feed x265 via | pipe).
