[gst-devel] matroskamux bug?

[Kocsis Tibor]

Hi,

I found a bug in the matroskamux, try this pipeline:

gst-launch -e videotestsrc is-live=1 ! video/x-raw-yuv ! x264enc ! \
 matroskamux ! filesink location="test1"   videotestsrc is-live=1 ! \
video/x-raw-yuv ! x264enc ! matroskamux ! filesink location="test2"  \
videotestsrc is-live=1 ! video/x-raw-yuv ! x264enc ! matroskamux ! \
 filesink location="test3"  videotestsrc is-live=1 ! video/x-raw-yuv \
 ! x264enc ! matroskamux ! filesink location="test4"  \
videotestsrc is-live=1 ! video/x-raw-yuv ! x264enc ! matroskamux ! \
filesink location="test5"   videotestsrc is-live=1 ! video/x-raw-yuv \
! x264enc ! matroskamux ! filesink location="test6"   \
videotestsrc is-live=1 ! video/x-raw-yuv ! x264enc ! matroskamux ! \
filesink location="test7"    videotestsrc is-live=1 ! \
video/x-raw-yuv ! x264enc ! matroskamux ! filesink \
location="test8"    videotestsrc is-live=1 ! video/x-raw-yuv ! \
x264enc ! matroskamux ! filesink location="test9"

When I press ctrl+c the following messages come:

(gst-launch-0.10:20785): GStreamer-CRITICAL **: gst_object_replace:
assertion `*oldobj == NULL || GST_IS_OBJECT (*oldobj)' failed
(gst-launch-0.10:20785): GStreamer-CRITICAL **: gst_object_replace:
assertion `*oldobj == NULL || GST_IS_OBJECT (*oldobj)' failed
... (4-5 times)

GST_DEBUG=3 says:

I have some issues with matroskamux in my application and try to debug
where is the problem, I don't know the bug above is important - is it
critical? (Maybe file to bugzilla?)
