Description of your issue, suggested solution and other information

When downloading a video I often need to convert it to a .ts (transport stream) file, which requires an additional step, typically running something like

ffmpeg "original_file.mp4" -c copy "new_file.ts"

Since ffmpeg supports .ts files, it would be handy if the --recode-video option also allowed specifying ts or mpegts as an option. At present if you try to specify either --recode-video ts or --recode-video mpegts you get "youtube-dl: error: invalid video recode format specified".

What I am requesting may or may not be similar to issue #11498, I didn't fully understand that issue but what I am asking for is a way to re-encode ANY video downloaded from ANY supported site as a .ts file, without having to do an additional separate run of ffmpeg. Most supported sites don't offer a .ts file natively, so I think the only way to do this would be to recode the file. You already support recoding to several other formats, so why not .ts?

There is one other thing I have discovered. When you get the video from certain sites it is already in .ts format but sometimes in small chunks that would just need to be combined. In such cases the .ts file(s) often contain embedded ATSC closed captions that can be displayed with no problem by a standard ATSC television. However when the .ts files are converted to some other format, the closed captions are either lost, garbled, or converted to a non-embedded format in a separate file (if that option is used), all of which are useless to ATSC television sets. So having the ability to save files that originate in .ts format as .ts files would be a big help for the hearing-impaired.
