[FFmpeg-user] Is ffmpeg capable of converting elementary stream to program stream without recompressing video/audio stream?

h.264 is not standardized for MPEG program stream.
MPEG transport stream is valid, as well as mpeg4 and mkv.

However, ffmpeg creates such a file:
ffmpeg -i input.264 -i audio.mp2 -map 0 -map 1 -c copy output.mpg

Better use something like this:
ffmpeg -i input.264 -i audio.aac -map 0 -map 1 -c copy output.mp4
