what's wrong with my mpeg2-ts pipeline
 
|
Hi all: For a mpeg2 TS stream, I
can playback it by playbin: gst-launch -v -v playbin
uri=file:///home/halley/media/video/mpeg2_ac3_ts.mpg but when I assemble the
pipeline with specified elements, video freeze after show the first frame, an
no audio out. gst-launch -v -v filesrc
location=/home/halley/media/video/ mpeg2_ac3_ts.mpg ! flutsdemux name=demuxer
demuxer.! queue ! ffdec_mpeg2video ! ffmpegcolorspace ! videoscale !
autovideosink demuxer.! queue ! a52dec ! audioconvert ! audioresample !
autoaudiosink Could you kindly tell me
where is wrong for my second pipeline, Great thanks. ZHAO,

Use "mad" instead of "a52dec".

I don’t think so. And
a quick try shows it doesn’t work. Debug information from
playbin shows it uses a52dec for AC3 decoder. I guess there are some
parameter like sync=false, push/pull. But doesn’t work. From:

queue sizes are too small so change each queue to this:
queue max-size-buffers=0 max-size-time=0 On Thu, Feb 12, 2009 at 5:35 AM, Zhao, Halley <[hidden email]> wrote: > Hi all: > > For a mpeg2 TS stream, I can playback it by playbin: > > gst-launch -v -v playbin > uri=file:///home/halley/media/video/mpeg2_ac3_ts.mpg > > > > but when I assemble the pipeline with specified elements, video freeze after > show the first frame, an no audio out. > > gst-launch -v -v filesrc location=/home/halley/media/video/ mpeg2_ac3_ts.mpg > ! flutsdemux name=demuxer demuxer.! queue ! ffdec_mpeg2video ! > ffmpegcolorspace ! videoscale ! autovideosink demuxer.! queue ! a52dec ! > audioconvert ! audioresample ! autoaudiosink > > > > Could you kindly tell me where is wrong for my second pipeline, Great > thanks. > > > > > > ZHAO, Halley (Aihua) > > Email: [hidden email] > > Tel: +86(21)61166476 > > iNet: 8821-6476 > > SSG/OTC/UMD 3W033 > > > > ------------------------------------------------------------------------------ > Create and Deploy Rich Internet Apps outside the browser with > Adobe(R)AIR(TM) > software.

I tried the following pipeline and it worked fine.
gst-launch filesrc location=/home/Hellboy_small.ts ! mpegtsdemux name=dec dec. ! queue2 ! mpeg2dec ! ffmpegcolorspace ! xvimagesink force-aspect-ratio=TRUE dec. ! queue2 ! a52dec ! audioconvert ! alsasink On Thu, Feb 12, 2009 at 4:13 PM, Zaheer Merali <[hidden email]> wrote: queue sizes are too small so change each queue to this: ------------------------------------------------------------------------------ Create and Deploy Rich Internet Apps outside the browser with Adobe(R)AIR(TM) software.

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 On Thu, Feb 12, 2009 at 5:18 PM, Sumanth V <[hidden email]> wrote: I tried the following pipeline and it worked fine. ------------------------------------------------------------------------------ Create and Deploy Rich Internet Apps outside the browser with Adobe(R)AIR(TM) software.

Thanks, but queue2 still doesn’t
work for my pipeline. While “queue max-size-buffers=0 max-size-time=0” works fine. From:
