Hello Solomax! Thanks for you input again! I used only --enable-libmp3lame, since that was the only one mentioned in the installation instructions at http://incubator.apache.org/openmeetings/installation.html . Do the instructions need updating?
Anyway, I don't think I'm having problems with ffmpeg. I now looked a little bit deeper into this, doing the following: 1. I went to my conference room and recorded a 1 min 10 sec clip at the highest quality. 2. The final output file, flvRecording_35.avi has this length, but the video only plays until around 10 seconds, super fast, then it stops there, as expected since that has been the behaviour here all the time. 3. The flv file containing the video ingredient for flvRecording_35.avi, called rec_35_stream_d579934cc40ab48c8604eb35a2243a31_13_12_2012_13_10_28.flv, is also only around 10 seconds. So, how is the raw flv video data being generated in OM; I guess the problem lies there? And, to rephraze my old question: I don't want to generate the avi file since it only wastes space for me, and I want to improve the sound quality. What part of the code do I need to tweak for that? If I want to try out later versions of OM than 2.0, where can I download these? I'm afraid that I'm partially struggling with bugs that might already have been fixed in later releases. (The Upgrading instructions on the apache openmeetings web page only talks about how to make and restore backups, not how to upgrade the OM installation.)
