<div dir="ltr">I have noticed a significant CPU cost for MP2T myself, though I run at *MUCH* lower bitrates. There is also the issue that MPEG2 TS breaks the bitstream into ridiculously small packets (188 bytes of data), which also imposes some burden. </div><div class="gmail_extra"> <div class="gmail_quote">On Wed, Oct 9, 2013 at 10:15 AM, cfadeley <<a href="mailto:chrisfadeley@gmail.com" target="_blank">chrisfadeley@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Has anyone else experience issues with the mpegtsmux plugin at high bitrates? Seems like any point higher than 3mb/s causes frames to be dropped by the ts muxer. I am streaming out to rtp using gst-rtsp-server. When compressing an image to a bitrate of 5mb/s I can do the following: encoder --> rtph264pay --> server and I will have the expected framerate produced all the way through the pipeline (30fps). But if I add a ts to the system: encoder -->mpegtsmux -->rtpmp2tpay -->server I get a much lower framerate of around 20fps. Again this only happens at higher bitrates and I can confirm it is not the encoder since I can watch the framerate out of the encoder. This results in the issue either at the mpegtsmux or the rtp payloder. And I doubt it is the later since it is so simple. I can also see that at higher bitrates the mpegtsmux plugin has a much higher CPU usage. And i would not be surprised if this causes the drops in frames due to the mpegtsmux failing to keep up. I am just curious if anyone else is aware of this issue and/or if it is only on my side of things. -- View this message in context: <a href="http://gstreamer-devel.966125.n4.nabble.com/mpegtsmux-at-high-bitrates-tp4662473.html" target="_blank">http://gstreamer-devel.966125.n4.nabble.com/mpegtsmux-at-high-bitrates-tp4662473.html</a> Sent from the GStreamer-devel mailing list archive at Nabble.com. _______________________________________________ gstreamer-devel mailing list <a href="mailto:gstreamer-devel@lists.freedesktop.org">gstreamer-devel@lists.freedesktop.org</a> <a href="http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel" target="_blank">http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel</a> </blockquote></div> </div>
