09/27/2022, 10:55 PMCould it be related to GST_PLUGIN_SCANNER?
a
able-gigabyte-21598
09/27/2022, 10:55 PMno, the error is
Copy code
gst_matroska_mux_video_pad_setcaps (): /GstPipeline:pipeline/GstBin:input: \nCaps changes are not supported by Matroskas

09/27/2022, 10:55 PMegressrec01 | (egress:21): GStreamer-WARNING **: 223722.873: 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.

09/27/2022, 10:56 PMthe track changed from 360x640 to 540x960, which matroska mux does not allow

09/27/2022, 10:57 PMI’m currently building a tool to better reproduce and test this case, and we should have a better fix in 1.4.2
able-gigabyte-21598
09/27/2022, 10:58 PMfor now, downgrading to v1.2.0 will fix it but you will receive .ivf files instead of .webm files
s
some-painter-46967
09/27/2022, 10:58 PMSo you're suggesting I use 1.2.0 ??
a
able-gigabyte-21598
09/27/2022, 10:59 PMyes, if you need this to work immediately
able-gigabyte-21598
09/27/2022, 10:59 PMotherwise, I will be releasing 1.4.2 sometime this week once I’m confident in the new fix

some-painter-46967
09/27/2022, 11:00 PMyes it should work for my client
some-painter-46967
09/27/2022, 11:00 PMOh, that's very good news.
some-painter-46967
09/27/2022, 11:07 PMYes, it continues to record with v120 without giving an error. thank you for your help.
What are your suggestions for stable operation in long (1 hour) broadcasts?
a
able-gigabyte-21598
09/27/2022, 11:22 PMit probably is taking a long time to finalize/upload the file
able-gigabyte-21598
09/27/2022, 11:23 PM0 byte file is a sign that the process was killed before it was able to complete
able-gigabyte-21598
09/27/2022, 11:23 PMmake sure it’s being stopped with StopEgress and that the docker container isn’t being killed
able-gigabyte-21598
09/28/2022, 6:18 AMJust pushed 1.4.2 - I was able to reproduce in 1.4.1 but not 1.4.2, but let me know if you see it again
