Nobody likes to see this. But what should you check when it happens?
Well first of all its a general error. And it tells you/the student that your recording will not be saved. That is important. At this point your recording is already gone. There is probably nothing you can do but re record.
Things to check
i) is the microphone capturing sound? Or the video camera capturing your picture.
If not, then there is nothing to submit or convert. And you might get this error.
ii) does a very short recording get submitted ok?
Sometimes longer recordings have problems at the server or browser level.
iii) what recorder are you using?
The two audio recorders look similar but are completely different. The video one is different again but in terms of troubleshooting its identical to the red5 audio recorder.
recordings get less reliable as they get longer. Best not to venture over 2 mins.
conversion to MP3 happens before the upload. If the file is too big it might spin forever and give up
if the upload begins but throws an error, the connection to the Moodle server is problematic. Check the browser console for errors related to the file being posted. Some servers restrict the upload file size. Thats a whole new ball game, but if thats the case small uploads will be working.
audio recorder/video recorder (red5):
if you can't play it back after recording....
then the file never arrived on the Red5 server.
Check the connection lamp on the recorder. Should be green. If its red or yellow your connection is bad (firewall? ) or the red5 server is down (happens.)
If you can play it back, but get the error message above ...
then the problem is that your file can't be collected from the Red5 server and copied back into Moodle.
- Turn off auto convert to mp3/mp4 in the filter settings and try again (or uncheck the mp3/mp4 checkbox on the recorder BEFORE recording). If conversion is the issue then its best to set up FFMPEG on the Moodle server and have PoodLL do its magic with that.
- Check the port settings in the PoodLL filter settings for HTTP. Your Moodle server will need to be able to do a server to server connection to that port on the Red5 server to pick up the recorded file.
