So, what you want to do is receive, demux, decode from jpeg, encode to
H264, mux into transport stream (TS) and then pass on the hlssink. So
something similar to:
souphttsrc ! multipartdemux ! jpegdec ! h264enc ! mpegtsmux ! hlssink
That's nearly a pipeline, but then you need to pick your H264 encoder
(h264enc is not a plugin), and the element is something that will vary
per installation. If you have a fully GPL installation (or personal
installation), you could use the very good encoder called x264enc (from
gst-plugins-bad). Touch aspect is to pick the params you want, here's
something that should generally work, but quality may be poor, play
with the bitrate to improve.
... ! x264enc tune=zerolatency bitrate=... ! ...
If you have Intel hardware, and the VAAPI plugins installed, you could
use your hardware:
... ! vaapih264enc bitrate=.. ! ...
If you have NVidia hardware, and NVENC plugins (from gst-plugins-bad)
installed (not completely sure of the name for this one):
.. ! nvh264enc ?? ! ...
If you have a PC and your distro has adhere to ship the completely free
OpenH264 Cisco encoder:
.. ! openh264enc ! ...
On RPi platforms, or many other OMX base boards:
.. ! omxh264enc ! ...
On mainline supported ARM platforms (e.g. Qualcomm, Exynos, IMX.6), you
could try your luck with (requires git master, upcoming 1.14):
.. ! v4l2h264enc ! ...
And there is countless other options, parameters, also CODEC you could
