After Upgrade: "...because the format is not supported"

[RudiFueller]

After the upgrade from 1.34 to 1.36 (CentOS 8, rpmfusion, first 1.36.1, now 1.36.3, no difference) the web interface shows "The video could not be loaded either because the server or network failed or because the format is not supported". This is somehow a little bit strange, because

1. old videos can still be viewed
2. downloading and viewing the new videos works as well in an external viewer like vlc.

I looked through numerous log files without any success, but have to admit that I am not a zoneminder expert. If you could point me in the right direction it would be really appreciated. I would be happy to provide the necessary config + log files.

Are you encoding? The encoding code is all new and will actually try to write the event files as h265. Also each encoder needs some default settings.

My advice is to select h264 as the codec and set crf=23 in encoder options for best UI.

[RudiFueller]

Yes, I am using ffmpeg. I am not absolutely sure where and how to switch these options.

I tried in Options / Images the FFMPEG_OUTPUT_OPTIONS and set

-crf 23 -vcodec libx264

Unfortunately I still get in the zmc_*.log:

06/06/21 18:41:26.652365 zmc_m2[132357].ERR-zm_videostore.cpp/256 [Failed to create hwdevice_ctx]

I am not sure if this describes the error. Thanks, iconnor for the quick reply but apologies for me being too dumb. Could you please advice a little more...

Those options are set in Storage for each camera.

Thanks, bbunge. This solved it.
