Trim a TS file

./tscut.py cut -t 188 --start 2000.115 --end 2100.015 input.ts output.ts

Concatenate two ts files

./tscut.py concat -t 188 input1.ts input2.ts output.ts

If two files overlap and the overlap is less than 2 sec, they are concatenated seamlessly (works with BD recorder files).

Trimming tutorial

1. ffplay -v quiet -vf "drawtext=fontsize=32:text='\''%{pts} %{pict_type}'\''" input.ts
2. ./tscut.py cut -t 188 --start A --end B input.ts output.ts where [A, B)

tscut.py trims ts files, ensuring the output includes [A, B) and both ends are terminated with I-frames.

You can use the -r, --relative-time option to use any player since pts checking is not required.
