Trim .tp files without re-encoding

I'm currently using ffmpeg -ss xx:xx -to yy:yy -i input -c copy output to cut some files and it works fine with .ts and .mp4, but it can't handle .tp files. Here's what I get:

[mpegts @ 0x198acd0] PES packet size mismatch

output.tp: Invalid argument

What's the problem here?

We may select the format manually by adding -f mpegts:

ffmpeg -f mpegts -ss xx:xx -to yy:yy -i input.tp -c copy -f mpegts output.tp

FFmpeg error is:

Unable to find a suitable output format for 'output.tp'

It means that FFmpeg can't select the format (automatically) for the file with the .tp extension.
The reason is that .tp extension is not a standard file extension (for FFmpeg).

FFmpeg recognizes that the input file is TS file, but we may add -f mpegts before the -i for helping FFmpeg identifying the input format.

Note:
I am not sure if your .tp file is fully compatible with MPEG-TS format (compatible with .ts file).
My answer assumes the format is compatible, but you may still get some errors.
