Unable to play mpeg video using gst-launch
Locked
 
|
Hello,
I am trying to use play a mpeg file using the following command: gst-launch-0.10 -v filesrc location=/home/mmes/Videos/MovieTra1950_3.mpeg ! flupsdemux ! mpeg2dec ! ffmpegcolorspace ! autovideosink But it is giving the following errors: "ERROR: from element /GstPipeline:pipeline0/GstFluPSDemux:flupsdemux0: Internal data stream error. Additional debug info: gstmpegdemux.c(2934): gst_flups_demux_loop (): /GstPipeline:pipeline0/GstFluPSDemux:flupsdemux0: stream stopped, reason not-negotiated ERROR: pipeline doesn't want to preroll." Any help is very much appreciated. Thanks, Deb |

if you are not sure of the decoder you must use
gst-launch-0.10 -v filesrc location=/home/mmes/Videos/MovieTra1950_3.mpeg ! decodebin ! autovideosink or else mpg gst-launch-0.10 -v filesrc location=/home/mmes/Videos/MovieTra1950_3.mpeg ! jpegdec ! ffmpegcolorspace ! xvimagesink

Thanks for your reply.
Actually i am able to play this mpeg file using playbin, but I would like to play this file using the mpeg2dec and flupsdemux, and here the problem arises. Strange thing is, when I am using playbin, I have observed that playbin internally using the elements flupsdemux and mpeg2dec, but when I am directly using these elements, it is throwing errors. Regards, Deb. |

In reply to this post by Debsu
I guess you need to provide codec_data with caps between demuxer and
decoder. When you play this file with playbin or decodebin using -v option, you get to see caps between demuxer and decoder, so use the same. - Sudarshan From: Debsu Sent: 22/11/2011 10:40 To: [hidden email]

Hello Sudarshan,
Thanks a lot, I will try that also. But can you tell me if it is possible to create a pipeline using mpeg2demux and mpeg2dec for playing mpeg file, apart from using playbin? I think for a simple mpeg file playback I don't need to set caps filter. Regrads, Deb |

What about something like:
gst-launch filesrc location=yourfile.mpg ! mpegdemux ! mpeg2dec ! ffmpegcolorspace ! autovideosink Thanks, David

I have already used this pipeline, the following are the result:

Even when I am using the following pipeline:
gst-launch -v filesrc location=./MovieTra1950_3.mpeg ! mpegdemux name=demuxer ! mpeg2dec ! autovideosink demuxer. ! mad ! autoaudiosink The pipeline is getting stalled after showing the following messages: Setting pipeline to PAUSED ...

Hello,
Can anyone tell me how to create a simple pipeline for mpeg file without using Playbin? i tried lot of options provided by the gst-launch man page, but it failed each time. Thanks in advance. regards, Deb. |

Hi,
Try adding a typefind element between the filesrc and mpegdemux (whilst adding "-v" to gst-inspect) and check the stream type is what you expect and compatible with mpegdemux.

Hi,
you should check what playbin does, try: $ GST_DEBUG_DUMP_DOT_DIR=. gst-launch playbin2 uri=file://... $ dot -T svg -O *gst-launch.PAUSED_PLAYING.dot -o pipe.svg && eog pipe.svg This will show you the formats detected and elements are choosen by playbin. Maybe this will help you. -- Regards, Soeren On 11/23/2011 11:13 AM, David Walker wrote: > Hi, > > Try adding a typefind element between the filesrc and mpegdemux (whilst > adding "-v" to gst-inspect) and check the stream type is what you expect > and compatible with mpegdemux. > > > On 23 November 2011 05:00, Debsu<[hidden email]> wrote: > >> I have already used this pipeline, the following are the result: >> >> gst-launch -v filesrc location=./Videos/MovieTra1950_3.mpeg ! mpegdemux ! >> mpeg2dec ! ffmpegcolorspace ! autovideosink >> *Setting pipeline to PAUSED ... >> Pipeline is PREROLLING ... >> /GstPipeline:pipeline0/GstMPEGDemux:mpegdemux0.GstPad:sink: caps = >> video/mpeg, mpegversion=(int)2, systemstream=(boolean)true, >> parsed=(boolean)true >> /GstPipeline:pipeline0/GstMpeg2dec:mpeg2dec0.GstPad:sink: caps = >> video/mpeg, >> mpegversion=(int)2, systemstream=(boolean)false >> /GstPipeline:pipeline0/GstMpeg2dec:mpeg2dec0.GstPad:src: caps = >> video/x-raw-yuv, format=(fourcc)I420, width=(int)368, height=(int)480, >> pixel-aspect-ratio=(fraction)40/23, framerate=(fraction)30000/1001, >> interlaced=(boolean)true >> ERROR: from element /GstPipeline:pipeline0/GstFileSrc:filesrc0: Internal >> data flow error. >> Additional debug info: >> gstbasesrc.c(2582): gst_base_src_loop (): >> /GstPipeline:pipeline0/GstFileSrc:filesrc0: >> streaming task paused, reason not-negotiated (-4) >> ERROR: pipeline doesn't want to preroll. >> Setting pipeline to NULL ... >> * >> >> -- >> View this message in context: >> http://gstreamer-devel.966125.n4.nabble.com/Unable-to-play-mpeg-video-using-gst-launch-tp4094645p4098528.html >> Sent from the GStreamer-devel mailing list archive at Nabble.com. >> _______________________________________________ >> gstreamer-devel mailing list >> [hidden email] >> http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel >> > > > > _______________________________________________ > gstreamer-devel mailing list > [hidden email] > http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel _______________________________________________ gstreamer-devel mailing list [hidden email] http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel |

Hi, works perfectly fine for me, I have latest gstreamer (core + plugins) installed in my machine. So just update your installation :)
