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
