Unable to determine movie duration while doing RTSP play

[智峰宋]

Hello

While using rtspsrc to play video stream (TS formatted movie), the application is failed to get the movie duration, so the movie can be seen but can't do forward / backward play or do actual timestamp seek. The failure shoud not be related to the RTSP server or the movie itself, because VLC can play it well.

The following command is used for the play:

rtspsrc location=rtsp://10.0.0.15:554/test buffer -mode=0 ! queue ! rtpmp2tdepay ! aiurdemux name=d d. ! queue ! vpudec low-latency=true ! queue ! mfw_v4lsink axis-left=400 axis-top=0 disp-width=640 disp-height=480 sync=true d. ! queue ! ffdec_ac3 ! alsasink sync=true

The log shows this is a live stream, and not seekable, as below:

So any one has experienced the similar issue?

or knows what command can play the TS-formated video stream by using RTSP and do play backward/forward well?

Thanks,

Frank

Let me attach the full log of the above rtspsrc command for reference. From the log,  the RtpMP2TDepay plugin can see the movie duration (below in red), but aiurdemux can't see it.

pls try to  use gplay, like "gplay rtsp://", you can find the time bar.

[huangbaokang]

hi: Xie

   The situation is that:

1、 "gplay rtsp://xx.xx.xx.xx/file.mpg" can get the time bar.

2、"gplay rtsp://xx.xx.xx.xx/file.ts" can not get the time bar.

so the problem is that , it  is not seekable when playing rtsp about ".ts" format video.

[huangbaokang]

Dear  song:

    I have the same problem as you.

    I find that , the "tsdemux"  plugin can get the duraton from RTSP(TS format MOVIE) . But  it can't seek . output an errror below:

(CQplayer:23191): GStreamer-CRITICAL **: gst_mini_object_unref: assertion `GST_IS_MINI_OBJECT (mini_object)' failed

and then ,CQplayer  play the rtsp back to the beginning.

HOW it can seekable when playing  RTSP  about  ".TS format video" ???
