Hello. I'm trying to stream from my remote device video, using h.264 codec to Firefox. Respectively i'm using h264 firefox's plugin. My command from gstreamer from remote device is:
gst-launch v4l2src always-copy=false chain-ipipe=true ! video/x-raw-yuv,format='(fourcc)'NV12, width=640, height=480, framerate='(fraction)'15/1 ! dmaiaccel ! dmaienc_h264 ddrbuf=true encodingpreset=2 profile=66 level=31 entropy=0 t8x8intra=0 aud=false headers=false bytestream=false seqscaling=0 ratecontrol=1 maxbitrate=4000000 targetbitrate=2000000 intraframeinterval=2 idrinterval=1 ! rtph264pay config-interval=1 ! queue ! udpsink port=3000 host=192.168.1.16 sync=false I able to catch them, using gstreamer on my local machine: gst-launch udpsrc port=3000 ! "application/x-rtp, media=(string)video, clock-rate=(int)90000, encoding-name=(string)H264, sprop-parameter-sets=(string)\"Z2QAKK2EBUViuKxUdCAqKxXFYqOhAVFYrisVHQgKisVxWKjoQFRWK4rFR0ICorFcVio6ECSFITk8nyfk/k/J8nm5s00IEkKQnJ5Pk/J/J+T5PNzZprQFAeyA\,aO48sA\=\=\", payload=(int)96" ! rtph264depay ! queue ! ffdec_h264 ! ffmpegcolorspace ! videoscale ! ximagesink sync=false show-preroll-frame=false And it works perfect without any delay. But when i try to catch the stream using firefox's h264 plugin (using janus-gateway to generate SDP), my video playing with huge delay. And that delay alway increases. Any thoughts about that? P.S. If i try to stream from my local machine, using x264 library to firefox, it works perfect. Is it because dmaienc_h264 can't negotiate with firefox's h264 plugin properly?
