Public bug reported: Few specific h264 and h265 RTSP input streams sources when used with nvidia specific gst-v4l2 based gstreamer-1.0 (version gst-1.14 and ubuntu-18.04) decode pipeline intermittently yields very low fps (in the range of [~0/1 fps]).
Issue seems caused by the gst_video_decoder_drain_out function erroneously getting called inside gst_video_decoder_chain_forward function. Required changes to fix the issue seems available with gst-1.16 and to resolve the issue need to backport the relevant OSS fixes from gst-1.16 to gst-1.14 on ubuntu-18.04. The mentioned issue was reported on with: https://bugzilla.gnome.org/show_bug.cgi?id=796771 Corresponding fix was incorporated with below: https://github.com/GStreamer/gst-plugins-base/commit/62cb08404b9bd055c45cc1d5b71141e927ad748a We need to backport above fix on top of gst-1.14.5 on ubuntu-18.04 in order to have out-of-box fix available with default gstreamer-1.0 version 1.14 on ubuntu-18.04 ** Affects: gstreamer1.0 (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gstreamer1.0 in Ubuntu. https://bugs.launchpad.net/bugs/1962133 Title: Intermittent very low fps(sometimes zero) with few specific h264 and h265 RTSP input streams sources when used with gst-v4l2 based gstreamer-1.0(version gst-1.14.5) decode pipeline Status in gstreamer1.0 package in Ubuntu: New Bug description: Few specific h264 and h265 RTSP input streams sources when used with nvidia specific gst-v4l2 based gstreamer-1.0 (version gst-1.14 and ubuntu-18.04) decode pipeline intermittently yields very low fps (in the range of [~0/1 fps]).
