The gstreamer bufferpool message is harmless.

This is your (X11) error, maybe to do with touchscreen?

X Error of failed request: BadValue (integer parameter out of range for operation)
Major opcode of failed request: 131 (XInputExtension)
Minor opcode of failed request: 46 ()
Value in failed request: 0xd
Serial number of failed request: 62
Current serial number in output stream: 66

You need to find what opcode 46 in XInputExtension means.

Sounds good, I will try to do some research on what opcode 46 means. Do you have any ideas on what the right direction to start looking would be for something like this?

fduncanh commented on August 25, 2024

Somewhere buried in X11 at X.org https://www.x.org/wiki/
but its not obvious how to find opcodes.

as a workaround, try uxplay -vs glimagesink

https://www.x.org/releases/X11R7.7/doc/inputproto/XI2proto.txt
https://www.x.org/releases/X11R7.7/doc/index.html

https://www.x.org/wiki/guide/extensions/#index2h2

https://codebrowser.dev/gtk/include/X11/extensions/XInput2.h.html

Try to see when the X11 error occurs (maybe when gstreamer creates the video window?

try uxplay -d to see how far uxplay gets before the error

then run uxplay after

export GST_DEBUG=2

(or 4, but try 2 first)
to see how far gstreamer gets.

The screen I am using has had some weird behavior I haven't seen on previous touch screens that I have used. Such as the refresh rate being displayed as 0hz in the screen configuration tool and all the rotate options being grayed out.

from uxplay.

fduncanh commented on August 25, 2024

@Boaztheostrich

if your system doesn't find glimagesink, you need to install it:

sudo apt install gstreamer1.0-gl

then try "uxplay -vs glimagesink"

If your touchscreen monitor is somehow breaking xvimagesink, glimagesink may get around the issue.

another possibility is "uxplay -vs gtksink". (install gstreamer1.0-gtk3 for that one)

see the README

Remind us what your system is: is it Raspberry Pi model 5 running Raspberry Pi OS (Bookworm) (full or desktop version, not "lite") or something else?

from uxplay.

fduncanh commented on August 25, 2024

Re the "bufferpool" message : I get it it too. Its some noise that gstreamer is making with no significance (error message spam)

from uxplay.

fduncanh commented on August 25, 2024

@Boaztheostrich

I can exactly reproduce your X11 error (same opcodes etc) (on a Pi model 4B with bookworm) when I use

uxplay -vs ximagesink

(this is an older X11 videosink without the "xv" extensions)
No touchscreen involved. Looks like Raspberry PI does not support this videosink.

but

uxplay -vs xvimagesink

which is the better X11 videosink, works fine.

Maybe you don't have the xvimagesink installed, (and autovideosink is choosing ximagesink)?

To see what you have installed, use

gst-inspect-1.0 | grep imagesink

(this needs gstreamer1.0-tools to be installed) On my system, this shows glimagesink, ximagesink and xvimagesink are available.

(install gstreamer1.0-x if it is not already installed) This provides libgstpango.so, libgstximagesink.so, and
libgstxvimagesink.so, so I dont see how you could be missing xvimagesink if you have ximagesink. Try "uxplay -vs xvimagesink" to see what happens.

See the README

fduncanh commented on August 25, 2024

For whatever reason your system (presumably the monitor) does not support the X11 "xv" video extension, and ximagesink (no v) seems broken on R Pi. Install glimagesink its a very good videosink, or gtksink.

from uxplay.

Boaztheostrich commented on August 25, 2024

glimagesink did work but I wasn't able to get it to run full screen and it was very laggy on my CM4. I wasn't able to get gtksink working.

Any ideas on what I could do to make the monitor accept the xv video extension?

from uxplay.

fduncanh commented on August 25, 2024

also try "uxplay -vs waylandsink"

glimagesink doesnt do fullscreen

waylandsink does.

You might need to use raspi-config to activate wayland (??)

from uxplay.

fduncanh commented on August 25, 2024

It's surprising that the monitor doesnt like xv, maybe you can find a fix. can you test a different monitor to confirm the monitor is the problem?

On my pi4 and 5 it hasn't been an issue at all, the cm4 carrier board I am using doesn't have an hdmi out I may be able to try a different carrier board tmw.

I do think you're right about it being the screen though. I tried to get the waylandsink working, switched from x11 to wayland in raspiconfig, and it refuses to boot to the desktop. There is just a blinking cursor top left corner.

But X11 works fine.

from uxplay.

fduncanh commented on August 25, 2024

@Boaztheostrich
since the failure of ximagesink (no v) occurs when uxplay starts streaming video, and I see it too, so its not a issue of your monitor (unlike the xvimagesink failure, which is) I can probably track it down.

UxPlay does some X11 manipulations (in renderers/x_display.h) at that time, and the ximagesink code is available in gstreamer. Quite possibly the code in x_display.h is triggering the X issue in ximagesink

from uxplay.

Boaztheostrich commented on August 25, 2024

Good stuff! But xvimagesink is an issue of the display? I’m talking to the manufacturer about that issue, but haven’t heard too much back yet.

fduncanh commented on August 25, 2024

The xvimagesink issue is that your system does not find xv support , so that is why autovideosink is choosing ximagesink instead of xvimagesink.

As a diagnostic for the ximagesink failure,
Try building uxplay with the cmake option -DNO_X11_DEPS=ON

This option just omits the code in renderers/x_display_fix.h

You will probably lose fullscreen mode of ximagesink, but it will show if the code in x_display_fix is the issue.
Then use uxplay -vs ximagesink

(I will check this out myself later but not immediately.)

EDIT: unfortunately, compiling with -DNO_X11_DEPS=ON doesnt fix the bug with ximagesink (no v).
That means its not anything that UxPlay is doing, its something making ximagesink incompatible with
R Pi. I'll try building and tweaking the gstreamer libgstximagesink code from gstreamer1.0-x

from uxplay.

fduncanh commented on August 25, 2024

the basic tests:

 gst-launch-1.0 -v videotestsrc ! ximagesink  fails  with " X Error of failed request: Badvalue ..."

 gst-launch-1.0 -v videotestsrc ! xvimagesink      works for me

I was able to rebuild gstreamer1.0-x, (same way as was done for the videoflip patch), so its possible to mess around inside the libgstximagesink code, but I have no idea what to do.
the ximagesink issue seems to be R Pi-specific, it works fine on a intel desktop with gstreamer-1.22.0. I suppose it should be reported to Raspberry Pi bugs.
the xvimagesink issue that @Boaztheostrich has seems specific to the 4" 800x480 touchscreen being used. This can be confirmed by using a different regular-size terminal (should be done since another possibility is that xv is misconfigured (missing requirement, etc)
since this is not a UxPlay issue I'll close it, but feel free to continue posting

from uxplay.

fduncanh commented on August 25, 2024

For what its worth, I booted the RPI 4B into an older ubuntu 22.04.LTS with gstreamer-1.20.1 and ximagesink works fine.

I tried again with ubuntu 23.04 with gstreamer 1.22.1 and ximagesink failed with the X error : Badvalue

so maybe gstreamer-1.22.x has the bug (on R Pi, not X86_64) but 1.20.x doesnt.

from uxplay.

fduncanh commented on August 25, 2024

I checked uxplay -vs ximagesink on ubuntu 23.10 which has gstreamer 1.22.6 get X badvalue error

manjaro RPi4 current with gstreamer-1.22.10 : ximagesink WORKS!

I dont yet know if a bug got fixed, or whether Arch/manjaro does a better build of gstreamer.

As expected, Raspberry Pi OS (Legacy, Bullseye) with gstreamer-1.18.4 has a working ximagesink

from uxplay.

Boaztheostrich commented on August 25, 2024

I installed raspbian os bullseye to see if I would have better luck with that.

But when I tried to install uxplat with

sudo apt install uxplay

It was unable to locate the package

from uxplay.

fduncanh commented on August 25, 2024

You need to build uxplay from github source for Bullseye: its very easy. Debian first included uxplay in Bookworm

yes, ximagesink works on bullseye. (but I'm not sure if RPi 5 works on bullseye?, RPi 4B will work)

https://github.com/FDH2/UxPlay#getting-uxplay

I replaced the GStreamer 1.22.0 in R Pi OS bookworm with latest 1.22.10 build from source: same ximagesink error.
1.22.0 has some reworking of ximagesink which might be the source of the problem. I'm waiting for ubuntu 24.04 to be released soon to see if gstreamer 1.24.0 also has the ximagesink bug.

from uxplay.

Boaztheostrich commented on August 25, 2024

Good stuff! I was able to build from source and got it running on bullseye. Would it be possible to just downgrade gstreamer on bookworm to get it working? I was also wondering if this # Enable DRM VC4 V3D driver #dtoverlay=vc4-kms-v3d #max_framebuffers=2 Would be impacting the latency at all? I feel like it’s definitely more laggy on this device with this touchscreen than it has been in the past. The previous devices may have been using the xv image sink though I’m not 100% sure.

I'm waiting for ubuntu 24.04 to be released soon to see if gstreamer 1.24.0 also has the ximagesink bug. — Reply to this email directly, view it on GitHub <#277 (comment)>, or unsubscribe <https://github.com/notifications/unsubscribe-auth/ATKHZWALTXZGYKC6HLYJGYDY2OTEZAVCNFSM6AAAAABFA24QASVHI2DSMVQWIX3LMV43OSLTON2WKQ3PNVWWK3TUHMZDAMRUGQZTONRWGA> .
