System details:

• Zorin 16 Pro based off ubuntu 20.04 LTS
• Version: ubuntu 20.04 LTS
• Package type: I installed directly from https://software.opensuse.org/download.html?project=home%3AIBBoard%3Acawbird&package=cawbird
• I also tried flatpak install with same issues

Additional context
Errors shown in cawbird (not terminal debug) Include:

• gstbaseparse.c(1370): gst_base_parse_sink_event_default (): /GstPlayBin:video/GstURIDecodeBin:uridecodebin7/GstDecodeBin:decodebin7/GstMpegvParse:mpegvparse12
• gstdecodebin2.c(4694): gst_decode_bin_expose (): /GstPlayBin:video/GstURIDecodeBin:uridecodebin7/GstDecodeBin:decodebin7:
  all streams without buffers

Running G_MESSAGES_DEBUG=cawbird cawbird can give useful debug output.

This is almost certainly an issue with the GStreamer version that your distro ships. There are instructions to test it here.

I was able to run gst-play-1.0 https://video.twimg.com/ext_tw_video/1243329209918988295/pu/vid/720x1280/kWa3JQP6QqlrW052.mp4?tag=10 and the video played correctly.

If it is then I have no idea where, because all we do is link to the exact same libraries. It will take a while to work out how to debug this.

I don't want to take up too much of your time, as I know you must be a busy man and I appreciate the help...however here is the DEBUG lvl 4 output when I click on a video in cawbird. Hope it helps. Feel free to analyze the log at your leisure as I'll be dropping this error project for the day, because I have other things to work on.

Thanks for the extra debug. That's all just telling me the same thing, though - it matches a known bug in GStreamer v1.18.

Can you post:

• The version of GStreamer you're running - gst-play-1.0 --version should do it
• The output of ldd /usr/bin/cawbird | grep gst
• The output of readlink -f $(ldd /usr/bin/cawbird |grep -oE '\S+/\S+gst\S+')

e.g. I get:

$ gst-play-1.0 --version
gst-play-1.0 version 1.18.6
GStreamer 1.18.6
http://download.opensuse.org
$ ldd /usr/bin/cawbird |grep gst
	libgstreamer-1.0.so.0 => /lib64/libgstreamer-1.0.so.0 (0x00007f9c78b8f000)
$ readlink -f $(ldd /usr/bin/cawbird |grep -oE '\S+/\S+gst\S+')
/usr/lib64/libgstreamer-1.0.so.0.1806.0

[Sifrqitt]

gst-play-1.0 version 1.16.2
GStreamer 1.16.2

libgstreamer-1.0.so.0 => /lib/x86_64-linux-gnu/libgstreamer-1.0.so.0 (0x00007f37984da000)

/usr/lib/x86_64-linux-gnu/libgstreamer-1.0.so.0.1602.0

v1.16? It's possible that it's not the same issue as above but that's quite an old version (December 2019 with 1.16.3 released in October 2020 before they moved to 1.18) so it could be that it has issues with newer videos or something.

I've released a fixed version of the Snap Packaged release of Cawbird that I maintain.
