[openmeetings-user] Re: Quality in the recordings
Hello, I am very interested too in recordings improvement and I downloaded this last version, r3822. I made a recording in a room and downloaded it into avi but when I see it on my local computer with vlc in the codec properties I can see that the frame rate is 1 I don't know how openmeetings deals with the frame rate in the code but maybe something is missing at some calculation. In my log I can see the following: DEBUG 06-17 09:46:50.039 FlvRecorderConverter.java 247229 633 org.openmeetings.app.data.flvrecord.converter.FlvRecorderConverter [openmeetings.TaskExecutor-1] - START previewFullFLV # DEBUG 06-17 09:46:50.040 FlvRecorderConverter.java 247230 634 org.openmeetings.app.data.flvrecord.converter.FlvRecorderConverter [openmeetings.TaskExecutor-1] - [Ljava.lang.String;@d07503 DEBUG 06-17 09:46:50.040 FlvRecorderConverter.java 247230 640 org.openmeetings.app.data.flvrecord.converter.FlvRecorderConverter [openmeetings.TaskExecutor-1] - ffmpeg -i /home/chema/Escritorio/ Openmeetings/webapps/openmeetings/streams/hibernate/flvRecording_1.flv -vcodec mjpeg -vframes 1 -an -f rawvideo -s 2176x1360 /home/chema/ Escritorio/Openmeetings/webapps/openmeetings/streams/hibernate/ flvRecording_1.jpg Regards.

Dear Sebastian, I'm sorry if I didn't understand the topic, but in the first post, lucimara julia talks about losing frames in the recording, that was my point too. So, the question is this: is there any way to do that the raw video has a higher framerate??something similar to the live video image???

Also the framerate has hardly sth. todo with the *quality* ... meaning of *sharpness* of the recording. The AVI that you download has (if you record with quality setting of *hihg* in the screensharer app) it has 1:1 the same size and quality as you can see it on your screen. So how much more quality can there be?! Same as initial mentioned = you cannot create a better output as you have in the input.

Re: [openmeetings-user] Re: Quality in the recordings
*is there any way to do that the raw video has a higher framerate?* = you would need to increase the quality in the screensharing client, which results in a bandwidth need multiple times more then what we have now. Think about it, your webcam has a frame rate of 32 fps, it is about lets say roughly 124x86 pixels, you have 70KByte/sec. 1280x1024 at 32 FPS would mean, 700 KByte/sec = No chance to get that through the network. Currently Screensharing has around 90KByte/sec, which is often still too much, so there are those buttons to decrease the quality of the screen, that results in less Bandwidth (but hardly *text-on-screen* readable) screensharing. Also the ScreenSharingCodec works different from a usual codec, because of the nature of screen use. So if you have the time of course you are welcome to start testing, debugging and implementing sth alternative with better results but we also spend quite some time to get it at the current level.
