[gst-devel] strange problem with video for gstreamer-0.23

Hi all,

I am launching a pipeline as below.

==================================================================================================================
gst-launch filesrc location=collateral.ts ! mpegtsdemux name=d d. ! \
queue name="vid_queue" max-size-buffers=0 max-size-time=0 *
max-size-bytes=8192* ! ffdec_h264 ! ffmpegcolorspace ! videoscale ! queue !
xvimagesink\
d. ! queue name="aud_queue" max-size-buffers=0 max-size-time=0 *
max-size-bytes=8192* ! mad ! audioconvert ! audioresample ! queue ! alsasink
==================================================================================================================

*Issues:

** the file only plays video & the audio is just heard for a second in the
beginning & then not heard at all.
* the same behavior is seen in application written for above pipeline.
* but the above pipeline works well with most of the files.
  eg: mp4 files(video-H.264, audio-AAC)

now if i change the queue property max-size-bytes=819200 all files plays
well in launch line

* but if i do the same in application for some files the video plays faster
(say at the rate of 2.0)
& audio is played at the normal speed.

I use the latest gstreamer-0.23 version.
But if i use gstreamer-0.22 version i don't see any problem.
the audio & video play at normal speed when queue property
max-size-bytes=819200.

can anyone give any hint or idea wat may be the problem?

Thanks,
Jyoti
