Compression of recordings

[Mikael Kurula <al...@gmail.com>]

Dear All,

First of all thanks for a great product! I installed OpenMeetings earlier in the week, and after some testing, I am greatly impressed. I hope to be able to use OM for my teaching instead of the unreliable proprietary software we currently use. I would be recording over 4h of teaching every week and I am a bit concerned over how much disk space this would require. 

I just made a test with my laptop's standard resolution 1280x800 with webcam at 30 fps. It seems 4 hours of this video would consume about 5/4 GiB of disk space. I find this quite much, and on the other hand I would not mind reducing the quality of the recordings a bit. (It is intended that the students participate live, not that they study archived recordings.) Is it somehow possible to tell ffmpeg to make a smaller-resolution video with higher compression to save space?

Friendly greetings,
Mikael

Hello!

Now I have not had any problems making recordings, since I stopped sharing the screen within recording. Anyway, I guess this should be reported as a bug in the tracker?

I do have some other questions on the topic of recording too, not bugs.

1. I would like to have better sound quality, since I suppose the sound requires little bandwidth compared to the video anyway? Are the sound quality parameters hard-coded into openmeetings or is it possible to increase the settings somewhere?

2. Is it possible to avoid creating the avi file? I have not yet found a purpose for it, and from what I can understand it doubles the space consumed by a video. (Huge amounts of data in my case.)

3. When I record at the setting "high quality", the video and sound are more or less in sync, but the frame rate seems very low: movements are not at all fluent. When I try to set it to "very high quality", the video is more or less equally jerky, but it proceeds very fast, so the video finishes way before the sound.

I wonder if the problem in 3. could be that I have a slow server? It is a 2 GB RAM/single processor 2 GHz virtual machine. I could not find any hardware recommendations of OM on the web.

Thanks again!

Mikael

Ok, I now tried making a test recording at smaller size. It did again not
work, and my log is being filled with messages such as the following:

Re: Compression of recordings

[Maxim Solodovnik <so...@gmail.com>]

to reduce size you can
1) change the area recorded
2) change the quality in the applet (the worst is 10fps + 3/8 picture size)

[Mikael Kurula <al...@gmail.com>]

Thanks for your quick reply, Maxim! Do you mean that I should reduce the
screen reso (does this help?) or does the screen sharing quality dropdown
also affect recording quality?

I'd like to avoid changing the code if possible. Then I'll rather try to
find more hard disk space. :)

Cheers,
Mikael

I'm afraid you need you need to
1) reduce recording/screensharing quality
or
2) modify OM code and add additional ffmeg parameters

Re: Dealing with MySQL timeouts

[Maxim Solodovnik <so...@gmail.com>]

You should run GUI or command line install after changing db.
Or maybe backup/restore if you need your rooms, users etc.

I have the same problem on recordings and I am taking same response about com.mysql.jdbc... kind of reports from the system. I have also checked that  "autoReconnect=true" option is already given on the connection string and also checked the permission or the connection of mysql server but could not find a proper solution.

I have the same problem on recordings and I am taking same response about com.mysql.jdbc... kind of reports from the system. I have also checked that  "autoReconnect=true" option is already given on the connection string and also checked the permission or the connection of mysql server but could not find a proper solution.  Is there a bit more specific information about error message?

The last packet sent successfully to the server was 90,881,924 milliseconds ago. is longer than the server configured value of 'wait_timeout'. You should consider either expiring and/or testing connection validity before use in your application, increasing the server configured values for client timeouts, or using the Connector/J connection property 'autoReconnect=true' to avoid this problem.

I have the same problem on recordings and I am taking same response about com.mysql.jdbc... kind of reports from the system. I have also checked that  "autoReconnect=true" option is already given on the connection string and also checked the permission or the connection of mysql server but could not find a proper solution.

Re: Dealing with MySQL timeouts

[Mikael Kurula <al...@gmail.com>]

Thanks, Solomax! I'm very grateful for your speedy and constant help! I created an issue in JIRA about the MySQL timeouts.

I now tried switching back to Derby by renaming derby_persistence to persistence and restarting the OM server. Fine. Then I tried connecting with the web browser and I got the attached error message. In the log I got the curses below.

Friendly greetings,
Mikael

Re: Dealing with MySQL timeouts

[Maxim Solodovnik <so...@gmail.com>]

Hello Mikael,

I can point to the 2 MySQL advantages:
1 it performs faster
2 you can query it while OM is running :)

If you don't like MySQL you can use postgres or oracle, or write
persistence.xml to the DB of your choice :)

I never saw timeout issues with MySQL. But feel free to file JIRA issue if
you feel you found a bug :)

Re: Dealing with MySQL timeouts

[Mikael Kurula <al...@gmail.com>]

Hi again!

Now I had no problems with recordings and mysql timeouts, even if I don't think the OM server has been used for days.

Anyway, since poor reliability was the only reason for me to switch away from the previous web conference software I was using, I'm not happy with the prospect of losing OM-recordings because of mysql timeouts. Therefore I now ask: why is mysql recommended? What are the drawbacks of using the default derby persistence?

Another question: I find it a bit difficult to follow the discussions here in the mailing list. Besides, this seems to be a clear bug, not an issue about how to use OM. Should I file a bug report in the issue tracker? Also, after some testing I might have a few other bugs and feature requests to report.

Re: Dealing with MySQL timeouts

[Mikael Kurula <al...@gmail.com>]

That's unfortunate... If it's of any help, then I'm using a CentOS 6 server
with the following version of mysql:

mysql  Ver 14.14 Distrib 5.1.66, for redhat-linux-gnu (x86_64) using
readline 5.1

My version of openmeetings is this:
apache-openmeetings-incubating-2.0.0.r1361497-14-07-2012_1108.tar.g<http://www.apache.org/dyn/closer.cgi/incubator/openmeetings/2.0-incubating/apache-openmeetings-incubating-2.0.0.r1361497-14-07-2012_1108.tar.gz>
z

and the version of the J connector is mysql-connector-java-5.1.22.tar.gz

We are using OpenJPA (not Hibernate)
and already have "TestOnBorrow=true" and DB connection pool :(
not sure what else can be done ... Never saw such exception on my machines

Re: Dealing with MySQL timeouts

[Mikael Kurula <al...@gmail.com>]

Good morning!

Very nice to see that this issue generates interest. By googling I found
these discussions:

http://wiki.pentaho.com/display/ServerDoc2x/Configuring+for+MySQL
http://www.coderanch.com/t/564390/Tomcat/CommunicationsException-tomcat-mysql

I would assume this is the problem. Can the solution outlined in the first
link solve the problem for OM as well?

Friendly greetings,
Mikael

Re: Dealing with MySQL timeouts

[Mahmut TEKER <te...@gmail.com>]

Hi,

There is a connection between this error (or info) and recording and 
sharing of the OM (or I guess like that). I have the same problem on 
recordings and I am taking same response about com.mysql.jdbc... kind of 
reports from the system. I have also checked that  "autoReconnect=true" 
option is already given on the connection string and also checked the 
permission or the connection of mysql server but could not find a proper 
solution.  Is there a bit more specific information about error message?

Thanks,

_Mahmut

Re: Dealing with MySQL timeouts

[Maxim Solodovnik <so...@gmail.com>]

The only time I have seen MySQL timeout was

MySQL wait_timeout was set to very small value (connection was dropped
immediately)

I never seen errors with such huge numbers

I saw your issue regarding recording, I'll hopefully will take a look at it
(Or maybe Sebastian will have some time)

Re: Dealing with MySQL timeouts

Hi again!


Today I have another question. As I understand, it is recommended to integrate OpenMeetings with MySQL. This I did, but it seems I run into problems with MySQL timeouts because of inactivity overnight, getting the following error message in the openmeetings.log:

Caused by: com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: The last packet successfully received from the server was 90,881,924 milliseconds ago.  The last packet sent successfully to the server was 90,881,924 milliseconds ago. is longer than the server configured value of 'wait_timeout'. You should consider either expiring and/or testing connection validity before use in your application, increasing the server configured values for client timeouts, or using the Connector/J connection property 'autoReconnect=true' to avoid this problem.

I found rather conflicting information on the appropriateness of setting autoReconnect=true when I googled. What is the recommended way of dealing with this in OpenMeetings?


I don't know if it is related or not, but these errors showed up when I finished a test recording. Then when I tried to go and watch the recording, I only get "The recording is not yet ready for watching" and it seems the recording didn't consume any disk space.


Id' be most grateful for any help!

Mikael
