Perhaps that would work better in major browsers:

  ... ! x264enc ! video/x-h264,profile=constrained-baseline ! mp4mux ! filesink
location=...

Basically chose a more widely supported encoding profile (otherwise you might
get high-444, which is not supported by any browser) and produce a fast-start
variant of ISOMP4 (headers first), rather then hiding a MPEG TS into a .mp4
file.
