Fails to stream with "GStreamer error: Internal data stream error"

[mrgame64]

I'm running UxPlay on a Radxa Zero (Amlogic S905Y) with Debian Buster on Linux 5.10. I have installed all possible GStreamer plugins under the sun (as per this guide: https://gstreamer.freedesktop.org/documentation/installing/on-linux.html?gi-language=c ), and I'm able to launch a GStreamer window when using gst-launch-1.0 videotestsrc ! videoconvert ! autovideosink

UxPlay launches just fine, as soon as I connect from my iPad (iOS 15), I briefly see a transparent window flash, and in the terminal after "Mirroring initialized successfully" I get "GStreamer error: internal data stream error." and "Re-launching server..."

I have previously tried RPiPlay, it would hold the connection just fine, but it doesn't display a window

EDIT: also tried with -vs ximagesink and -vs glimagesink but to no avail

First check your ximagesink plugin gst-launch-1.0 videotestsrc ! videoconvert ! ximagesink repeat with xvimagesink

Assuming you have a working ximagesink (or xvimagesink) try without audio in case the problem is autoaudiosink uxplay -a -vs ximagesink

post the output of uxplay -vs ximagesink.

UxPlay works with iOS 15 clients.

No response, so closing. Re-open if needed

Hello, I have the exact same behavior and error here, on debian testing, amd cpu and graphics.

I run with the following:

uxplay -vs ximagesink

Then I get:

using system MAC address 6c:4b:90:58:8c:96
Initialized server socket(s)

and after connecting with iOS 15.4 I get:

You have a gstreamer error of some kind.
try different video plugins (-vs glimagesink, -vs gtksink etc)

do

export GST_DEBUG=2

before running uxplay to get some more info about the problem.

(export GST_DEBUG=4) give a LOT more information. Hopefully debug level 2 is enough to see what your issue is.

what does uname -a report about your system?

[fduncanh]

also try the -avdec option to force software video decoding.

(your debian system might be missing some "non-free" stuff for hardware decoding.)

I encountered the same problem on Ubuntu 20.04.

This just means that the gstreamer pipeline couldnt be constructed

GStreamer error: Internal data stream error

see if

export GST_DEBUG=2

before running uxplay tells you what is wrong. also try -vs xvimagesink, -vs glimagesink -vs gtksink, etc. and -avdec

Appreciate your great input!! I am a new user on Ubuntu. ......L600N:export GST_DEBUG=2 ......L600N:~/Downloads/UxPlay-master/build$ ./uxplay -vs xvimagesink 0:00:00.118936060 8856 0x5557068d3b80 WARN GST_ELEMENT_FACTORY gstelementfactory.c:456:gst_element_factory_make: no such element factory "h264parse"! 0:00:00.118986460 8856 0x5557068d3b80 ERROR GST_PIPELINE grammar.y:816:priv_gst_parse_yyparse: no element "h264parse" 0:00:00.119014461 8856 0x5557068d3b80 ERROR GST_PIPELINE grammar.y:901:priv_gst_parse_yyparse: link has no sink [source=@0x5557067f8dc0] 0:00:00.120010735 8856 0x5557068d3b80 ERROR GST_PIPELINE grammar.y:901:priv_gst_parse_yyparse: link has no source [sink=@0x5557068e4120]

I just fixed it by the following : sudo apt-get install gstreamer1.0-plugins-bad

it runs very well! Tks!

In debian sid the the error is the same as @panchiao220 but his solution doesn't work.

Steps to reproduce:

• install debian sid
• activate experimental repository (add deb http://deb.debian.org/debian experimental main to sources.list)
• apt -t experimental install uxplay

@scovit

GStreamer error: Internal data stream error.

This is a very generic error, just means that GStreamer failed to construct a pipeline, because of missing plugins etc. You need to give more details. However I will try to see if sid's package is working.

issue moved to new issue #90

[fduncanh]

@scovit I tested on Sid see issue #90

seems to work perfectly. Please respond in issue #90
