Summary: [audiodecoder] Timestamp and buffer tracking not
threadsafe and robust
Classification: Platform
Product: GStreamer
Version: git
OS/Version: Linux
Status: NEW
Severity: major
Priority: Normal
Component: gst-plugins-base
AssignedTo: gstreamer-bugs at lists.freedesktop.org
ReportedBy: slomo at circular-chaos.org
QAContact: gstreamer-bugs at lists.freedesktop.org
GNOME version: ---
audiodecoder keeps a queue of pending input buffers that is filled before
calling handle_frame() and cleaned in finish_frame(). For elements that have a
different streaming thread on the srcpad (gst-omx, gst-amc, probably others)
this can lead to buffers being removed from the queue while the subclass is
inside handle_frame() and uses them.
Also the solution to just drop all frames from the queue if -1 is passed to
finish_frame() is breaking timestamp tracking if the decoder still has input
queued when outputting something.
