This happens to me on both our productive and our test server (Moodle versions 3.5.1 (Build: 20180831) and 3.5.2 (build 20180910))
PHP Version is 7.0.27-0+deb9u1
- I set both post_max_size and upload_max_filesize in my php.ini to 2G
- Course upload limit is also set to site default (500G)
- I have no problem uploading large files via drag and drop
- RecordRTC still stops after 10 seconds
Any ideas what else could be the problem?
