http://people.igalia.com/psaavedra/gst-wpe-nightly_debug_logs.tgz and https://people.igalia.com/psaavedra/gst-wpe-nightly_debug_logs_v2.tgz -> this is the full GST debug info running this scenario: # Lower rank of AV1 decoder to disable it
export GST_PLUGIN_FEATURE_RANK="avdec_av1:0"
# Set directory for GStreamer debug output
export GST_DEBUG_DUMP_DOT_DIR=/tmp/gst-out/
export GST_DEBUG='*:DEBUG'
unset WEBKIT_GST_DISABLE_GL_SINK # == export WEBKIT_GST_DISABLE_GL_SINK=1context: running versions:
btw, it the non working scenario: there is a slightly improvement in gst 1.24 (9FPS) comparing to 1.22 (FPS) |

I’m investigating a performance regression in WPEWebKit main compared to 2.46 on RPi5 (Mesa).
The summary is the following:
WEBKIT_GST_DMABUF_SINK_ENABLED=1), Big Buck Bunny 1080p plays smoothly at 30 FPS.WEBKIT_GST_DMABUF_SINK_DISABLED=0), FPS drops to 3 FPS, with significantly higher CPU usage.Debugging So Far:
USE(GBM) is ON.s_isDMABufDisabledininitializeDMABufAvailability()is set correctly (to 0).
