Track 2 and Sub-titles lost in FFMpeg conversion

Question

I want to convert my video library to MP4 using:

ffmpeg -i inputfile.ts -c copy outputfile.mp4

However, outputfile appears to contain one audio track which is the NAR track from the inputfile.

The input TS files are made by an elderly Humax Foxsat and have two audio tracks - Track 1 = NAR & Track 2 = English, and 3 sub-title tracks. Only Audio Track 1 is present in the MP4 conversion.

The output from ffmpeg is:

By default ffmpeg will only map one video, audio and subtitle track to the output. You can see this in the log here:

Stream mapping:
  Stream #0:0 -> #0:0 (copy)
  Stream #0:1 -> #0:1 (copy)

To map all tracks, use -map 0:

ffmpeg -i inputfile.ts -c copy -map 0 outputfile.mp4

See also here.

Note that in some cases not all types of tracks can be mapped to an output file with stream-copying (-c copy). For example, MP4 does not support certain types of subtitle formats. In that case, you have to convert the format or leave it out during mapping (i.e. only map what can be copied).
