Bug ID: 97240 Summary: VCE encoding sometimes locks up since 4.8-rc1 Product: DRI Version: unspecified Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component: DRM/AMDgpu Assignee: dri-devel@lists.freedesktop.org Reporter: haagch@frickel.club
RX 480 with mesa git etc.
Running this gstreamer pipeline
gst-launch-1.0 -e filesrc location=big_buck_bunny_720p_1mb.mp4 ! qtdemux ! decodebin ! videoconvert ! omxh264enc ! h264parse ! matroskamux ! filesink location=/tmp/output.mkv
works fine on 4.7.
On 4.8-rc1 running it a couple of times randomly locks up the gst-launch process. Then while it hangs, running glxgears or so locks up everything. On the plus side, when it works, it works a lot quicker on 4.8.
I'll look into bisecting unless someone else can reproduce and already knows why it happens.
