lz4: fix shadow variables, again…
tycat: show a media properly in precise area

Summary:
Precise multimedia size/type/aspect ratio could be acquired after first frame has been decoded.

Therefore,

Fixes T1376

1. put every file in the queue, and handle them one by one
2. in case of video, block queue handling until "frame_decode" callback is invoked.
3. to avoid infinite blocking, put timer for timeout check

Test Plan:
1.terminology -> tycat "video file" -> check whether the video size is fit to real video size
2.            -> tycat "audio file" -> check whether black area is shown or not
