Did you try to find out what takes so long?
Seeking, decoding, encoding (or even startup of the executable)?
ffmpeg -i input.ts out.jpg
ffmpeg -ss 18 -i input.ts -vframes 1 -f null -
ffmpeg -ss 18 -i input.ts -vframes 1 -vcodec copy -f rawvideo /dev/null

Why do you need the select filter?
Nowadays, FFmpeg should seek to a keyframe.
If I am wrong, please provide complete, uncut console output.
