RTSP Streaming Internal data flow error

[yoheiitaya]

Hi, community.

I tried to receive and display a RTSP Streaming from ip camera on i.MX6Q SABRE.

I tried the following GStreamer pipeline, and some cameras works fine.

# gst-launch-1.0 rtspsrc location=rtsp://192.168.100.30/profile?token=media_profile1&SessionTimeout=60 ! rtph264depay ! vpudec ! overlaysink overlay-top=384 overlay-left=512 overlay-width=512 overlay-height=384 sync=false

But on a specific camera, the following error has happened, and could not run the GStreamer.

Setting pipeline to PAUSED ...

The error is Internal data flow error, and it seemed pipeline is not linked.

Anyone know, how to solve this problem?

Thanks.

I used the command as below successfully, but my rtsp from vlc, maybe you can refer to it.

gst-launch-1.0 rtspsrc location=rtsp://192.168.0.105:10000 name=source ! queue ! rtph264depay ! vpudec ! overlaysink source. ! queue ! rtpmp4gdepay ! aacparse ! beepdec ! alsasink

Thank you for reply, Guanqiong.

Sorry for reply to your comment.

I tried the command you taught me, but the result was same.

I estimate that, the real factor of this error is, the "rtspsrc" element  or anything else.

So, should I try to another pipeline element instead anything?

Payloader or videosink element are should not concerned?

Do you know any other way?

Thanks.
