[gst-devel] what's wrong with my mpeg2-ts pipeline

[Zhao, Halley]

Thanks,
but queue2 still doesn’t work for my pipeline.

While  “queue max-size-buffers=0 max-size-time=0” works fine.

Use "queue2" in place of  "queue" it should work fine.

I tried with the pipeline which u are using and it worked fine for me with following small changes.
* i used "mpegtsdemux" in place of "flutsdemux"
* "queue2" in place of "queue1"

gst-launch filesrc location=/home/MpegTSFile.ts ! mpegtsdemux name=demuxer demuxer.! queue2 ! ffdec_mpeg2video ! ffmpegcolorspace ! videoscale ! xvimagesink force-aspect-ratio=TRUE demuxer.! queue2 ! a52dec ! audioconvert ! audioresample ! autoaudiosink

queue sizes are too small so change each queue to this:

queue max-size-buffers=0 max-size-time=0
