I am trying to write gstreamer pipeline to convert mpeg4 video to mpegts
format.
I tried below pipeline but no luck
$ gst-launch-1.0 -e filesrc location=20200818125158_00001.ts.mp4 ! qtdemux
name=mdemux ! \
h264parse ! video/x-h264,stream-format=byte-stream ! mpegtsmux name=mux !
filesink location=20200818125158_00001.ts
Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
WARNING: from element /GstPipeline:pipeline0/GstQTDemux:mdemux: Delayed
linking failed.
Additional debug info:
./grammar.y(510): gst_parse_no_more_pads ():
/GstPipeline:pipeline0/GstQTDemux:mdemux:
failed delayed linking some pad of GstQTDemux named mdem
Based on previous questions I tried changing pipeline to
$ gst-launch-1.0 filesrc location=why.mp4 ! qtdemux ! h264parse ! mpegtsmux
! filesink location=1.ts
and I get
Setting pipeline to PAUSED ...
