Subject: [EXTERNAL] [FFmpeg-user] Parse a transport stream and get just 1 program

Friends,
I have a file.ts
It seems to contain 4 programs.
I can see this by when I play it in VLC I can select what I want by Playback - Program and picking the top of the 4 listed..
Ffmpeg shows the following

My goal is to have a file.ts that contains just the "1st" program The video , audio and captions.

I think that is  would be this part

Program 1
    Stream #0:2[0x51]: Video: mpeg2video (Main) ([2][0][0][0] / 0x0002), yuv420p(tv, top first), 1920x1080 [SAR 1:1 DAR 16:9], Closed Captions, 29.97 fps, 29.97 tbr, 90k tbn, 59.94 tbc

    Stream #0:10[0x56](spa): Audio: ac3 (AC-3 / 0x332D4341), 48000 Hz, stereo, fltp, 192 kb/s

And I think I can solve this with mapping Ending with a file.ts with just the 1 video,audio

What would be the  correct means to achive this?

Thanks much!

I was trying map without full success.
I think this works
ffmpeg -i MTP.ts -y -c copy -map p:1 mtp_1.mpg

I still wonder if there is a better way?
