gstreamer missing a lot of frames?

Tue May 19 14:29:14 PDT 2015

Video from: http://download.blender.org/peach/bigbuckbunny_movies/big_buck_bunny_1080p_h264.mov

Using gstreamer/plugins from the latest git clone, this seems to work fine:

gst-launch-1.0 -v videotestsrc ! vaapiencode_h264 ! vaapiparse_h264 ! rtph264pay ! udpsink host=127.0.0.1 port=6000

gst-launch-1.0 udpsrc caps = "application/x-rtp, media=video, clock-rate=90000, encoding-name=H264, packetization-mode=1, profile-level-id=42c00d, sprop-parameter-sets=\"Z0LADatAoPn/gACAAIgAAAMACAAAAwHkIA\\\=\\\=\\\,aM48gA\\\=\\\=\", payload=96, ssrc=2360089092, timestamp-offset=2801204503, seqnum-offset=3735" port=6000 ! rtpjitterbuffer! rtph264depay ! vaapiparse_h264 ! vaapidecode ! vaapisink

But any video I try to stream has very high amounts of frame/dropping stuttering, with or without sync on the receiver. Incoming/Outgoing data rates from nload are equal.

gst-launch-1.0 filesrc location=/home/dev/big_buck_bunny_1080p_h264.mov ! qtdemux ! vaapiparse_h264 ! rtph264pay ! udpsink host=127.0.0.1 port=5000

gst-launch-1.0 udpsrc caps = "application/x-rtp, media\=video, clock-rate=90000, encoding-name=H264, packetization-mode=1, profile-level-id=4d4029, sprop-parameter-sets=\"J01AKakYDwBE/LgDUBAQG2wrXvfAQA\\\=\\\=\\\,KN4JyA\\\=\\\=\", payload=96, ssrc=765248706, timestamp-offset=4096462552, seqnum-offset=1276" port=5000 ! rtpjitterbuffer! rtph264depay ! vaapiparse_h264 ! vaapidecode ! vaapisink

Local playback looks fine, but streaming looks poor regardless of trying several different videos attempted. Does this play smooth for others?
