FFmpeg - Extracting video and audio from transport stream file (.ts)
Solution 1
I could get SPTS from MPTS in ffmpeg by extracting required streams and remuxing it. My mpts has 6 streams for three programs (one audio, one video):
ffmpeg -i mpt.ts -map 0:0 -map 0:1 -acodec copy -vcodec copy -f mpts program1.ts
Solution 2
try:
ffmpeg -i input.ts -map 0:0 -map 0:1 -acodec copy -vcodec copy output.ts
Modify map values according to your input.ts programs.
Solution 3
try:
`cat *.ts | ffmpeg -i pipe: -c:a copy -c:v copy output.mp4`

I wish to extract the audio and video of a certain program in a transport stream file (.ts) by specifying its PID without losing quality and using the same codec in the resulting file (the output file is a MPEG).
Is that even possible with FFmpeg? If so, how can I do it?
So far, I've come to this command:
ffmpeg -i tsfile.ts -vcodec copy -acodec copy -q:v 1 output.mpg
Edit: Note that the file output.mpg is created. The file contains the video but the audio isn't attached (no sound). Also, I am unable to specify the program PID to extract.
Edit 2: Here's the output of ffmpeg -i tsfile.ts

Here's a tsinfo.exe on the .ts file:
