#9141: Input seeking -t/-to totally ignored when seeking MPEG-TS recorded from TV
(stream copy only)

Summary of the bug:
No bug if put -t after -i (-ss is still before -i), stream copying or
transcoding:
Good:
{{{
ffmpeg -ss 10:00 -i t.ts -t 1:00 -c copy ss_i_t_copy.ts
ffmpeg -ss 10:00 -i t.ts -t 1:00 -preset ultrafast ss_i_t_encode.ts
}}}
No bug when -t is before -i, but transcoding:
Good:
{{{
ffmpeg -ss 10:00 -t 1:00 -i t.ts -preset ultrafast ss_t_i_encode.ts
}}}
However, -t is totally ignored when when -t is before -i and stream
copying:
Bad:
{{{
ffmpeg -ss 10:00 -t 1:00 -i t.ts -c copy ss_t_i_copy.ts
}}}
The above will just trim my video from 10:00 to the very end, instead of
1min.
How to reproduce:
