Command without need encode

[RonRog]

i have this command

uridecodebin uri=rtmp://127.0.0.1/test/test ! x264enc ! mpegtsmux ! multifilesink location=/%05d.ts sync=true next-file=key-unit-event post-messages=true

This need a lot of cpu, because have x264enc, but the input already in h264. How i can do the same but without need encode and with audio?

Do a h264parse instead of x264enc, that will ensure that if you have any
kind of h264 input (byte-stream or avc) it should work with your
mpegtsmux

I've already been tried this, no error or file is generated that way.

dont wotk and without error
uridecodebin uri=rtmp://127.0.0.1/test/test ! h264parse ! mpegtsmux ! multifilesink location=/%05d.ts sync=true next-file=key-unit-event post-messages=true

work but without sound and a lot of cpu
uridecodebin uri=rtmp://127.0.0.1/test/test ! x264enc ! mpegtsmux ! multifilesink location=/%05d.ts sync=true next-file=key-unit-event post-messages=true

work fine but need set input codec
rtmpsrc name=rtmpsrc location=rtmp://127.0.0.1/test/test timeout=5 ! queue ! flvdemux name=demuxer ! queue ! aacparse ! muxer. demuxer. ! queue ! h264parse ! mpegtsmux name=muxer ! multifilesink location=/%05d.ts sync=true next-file=key-unit-event post-messages=true

I want a way to do this automatically, without even using the h264parse, something that works with any input which is already in the correct format, similar to copy of ffmpeg.

That's because uridecodebin decodes, so the whole h264parse ... sink
branch will never be linked and thus doesn't preroll. You should get a
warning in newer versions of gst-launch.

Right, because you decode and then re-encode.

There's parsebin in newer versions of GStreamer, so you might be able
to do something like:

 mpegtsmux name=mux ! filesink location=foo.ts \
 rtmpsrc ! parsebin name=parse \
   parse. ! queue ! mux. \
   parse. ! queue ! mux.

- completely untested though!

Thank you all for the attention!
Sorry for my ignorance, in this case the place of rtmp link it's on property location?

I have tried this with gstreamer 1.10:
gst-launch-1.0 mpegtsmux name=mux ! filesink location=foo.ts \
   rtmpsrc location=rtmp://127.0.0.1/test/test ! parsebin name=parse \
   parse. ! queue ! mux. \
   parse. ! queue ! mux.

Anyway I get an error:

Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
ERROR: from element /GstPipeline:pipeline0/GstRTMPSrc:rtmpsrc0: Internal data stream error.
Additional debug info:
gstbasesrc.c(2950): gst_base_src_loop (): /GstPipeline:pipeline0/GstRTMPSrc:rtmpsrc0:

ERROR: pipeline doesn't want to preroll.
Setting pipeline to NULL ...

Can someone help me?
