gst123 fails to play mp4 video file

English Multimedia
1

Hi,
my linux box has been upgraded from LEAP 15.2 to LEAP 15.3.

Eventually I discovered that gst123 fails to view mp4 video file, while totem, ffplay and xine render them fine. By the way, gst123 is able to play audio files (verified with mp3).

Multimedia stuff is installed from packman repository.

Starting gst123 with debug activated shows that it switches file extension from .mp4 to .str and thus fails to open that file. Anyway this is only reported as warning.

LANG=C GST_DEBUG=2 gst123 /home/name/Downloads/sample_640x360.mp4

Later it does fail due to not found renderer!


0:00:00.428190119 11383 0x7f5fb00ad850 ERROR                default cogl-gst-video-sink.c:1266:cogl_gst_video_sink_parse_caps:<coglgstvideosink0> could not find a suitable renderer

But what might be missing? Gstreamer based totem is happy.

What should I check?

An SRT file or SubRip (.srt) file is one of the most common types of raw closed caption file formats or subtitle formats.

Thank you. So trying that .srt is just an option and explain why it’s reported as warning.

So, remaining question is, what to check to resolve renderer issue. I forgot to mention that ff renders video and cheese works with USB web cam too.

More info:

gst123 --full-version
gst123:    0.3.5
GStreamer: 1.16.2-0
GTK+:      2.24.32
GLib:      2.62.6

Deleting gstreamer cache does not help. But first run after clearing gstreamer cache every application using gstreamer (e.g. totem), show this message once:

(totem:23119): GStreamer-WARNING **: 09:31:06.715: External plugin loader failed. This most likely means that the plugin loader helper binary was not found or could not be run. You might need to set the GST_PLUGIN_SCANNER environment variable if your setup is unusual. This should normally not be required though.

Conclusion: it’s a warning, an external plugin loader seems not to be installed.
gstreamer cache gets rebuilt and totem starts playing video.

My setup has NVIDEA graphics card and uses nouveau driver, that runs fine. Packages libvdpau1 and libvdpau_nouveau are in place. But libgstvdpau is not. Might this trigger the issue? No, it does not.

GStreamer: 1.16.2-0

No updates? Check what repos you’re using. Leap 15.3 has 2 new repos from SLE.

My system knows

Update repository with updates from SUSE Linux Enterprise 15
Update repository with debuginfo for updates from SUSE Linux Enterprise 15

Is that ok?
