Summary: [0.11] - not able to get pad from encodebin
Classification: Platform
Product: GStreamer
Version: git
OS/Version: Linux
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: gst-plugins-base
AssignedTo: gstreamer-bugs at lists.freedesktop.org
ReportedBy: Uraeus at linuxrising.org
QAContact: gstreamer-bugs at lists.freedesktop.org
GNOME version: ---
I got the following code:
origin = src_pad.query_caps(None)
c = origin.to_string()
if not c.startswith("text/"):
if not (c.startswith("video/") and (self.videocaps == False)):
print "creating sinkpad"
print "origin is " + str(c)
sinkpad = self.encodebin.emit("request-pad", origin)
print "src_pad is " +str(src_pad)
print "sinkpad is " +str(sinkpad)
src_pad.link(sinkpad)
But it seems to fail with the following error:
creating sinkpad
origin is audio/x-raw, format=(string)F32LE, rate=(int)44100, channels=(int)2
src_pad is <GhostPad object at 0x922d234 (GstGhostPad at 0x8ed3b00)>
sinkpad is None
Traceback (most recent call last):
