[oktastradllin]

hello i try use go run main.go gstreamer but always stuck on exit status 1 with error can't make element: h264parse

do you know what is the problem ?

i try print h264parse from h264parse := gst.ElementFactoryMake("h264parse", "h264parse_01")

always got nil , I try reinstall gstream and gst-plugin but still error ,

my laptop MacBook Pro with Catalina OS , and my device iOS 13.7

h264parse is in the gst-plugins-bad package (don't know why but I had to reinstall it, to get h264parse) avenc_aac and avdec_h264 are in gst-libav
