Hi Maxim, On my machine conversion to *.mp4 by latest code not being done.
I debug the conversion related code and It is not showing any error on console. So that’s why I ran conversion command from command line and it is showing : Unknown encoder 'libfdk_aac' . Do I need to upgrade any software like ffmpeg etc? Command I copy after debugging and ran to command line is below: E:\open-meeting\software\ffmpeg-latest-win64-static\bin\ffmpeg -y -itsoffset 00:00:03.624 -i E:\itutor\From-Maxim\openmeetings\openmeetings-server\target\server\webapps\openmeetings\streams\2\rec_13_stream_5af652f7-359f-4fc4-af72-ccaa1094ba48_2017_09_27_19_04_46.flv -i E:\itutor\From-Maxim\openmeetings\openmeetings-server\target\server\webapps\openmeetings\streams\2\rec_13_stream_7472625F-992B-BBEE-6C50-C37959682BD5_2017_09_27_19_04_46_FULL_WAVE.wav -c:v h264 -crf 24 -pix_fmt yuv420p -preset medium -profile:v baseline -c:a libfaac -c:a libfdk_aac -ar 22050 -b:a 32k -s 1024x576 E:\itutor\From-Maxim\openmeetings\openmeetings-server\target\server\webapps\openmeetings\streams\hibernate\62aa7f62-ca02-4a42-b45d-10cf7fd4ede1.mp4 Thanks, Amit From: Maxim Solodovnik [mailto:solomax...@gmail.com] Sent: Wednesday, September 27, 2017 4:47 PM To: K, Amit (MIND) <ami...@mind-infotech.com> Cc: user@openmeetings.apache.org Subject: Re: Warning!!!PossibleSpam Re: Warning!!!PossibleSpam Re: Recording stop case: 4.0.0: If existed unexpected Works as expected both locally and on demo server I need reproducible steps The error you are observing might be "displayed" due to stream is being closed twice This should not affect conversion process On Wed, Sep 27, 2017 at 6:11 PM, K, Amit (MIND) <ami...@mind-infotech.com<mailto:ami...@mind-infotech.com>> wrote: Hi Maxim, I cleaned all modules and build again and recording is saving successful as *.flv.

Jump to the conference room directly by using API call. 2. Click on the icon top right ( “Open new dialogue with sharing screen” title shown) to download JNLP (applet). 3. Run applet. 4. Now click on “Start Recording”. 5. After few minutes just close applet by click on Close button (Top right cross button in applet). Output: As cross button is clicked, recording stopped immediately and *.flv is created successfully but no conversion is done so no *.mp4 file created in /hibernate directory.

Stream is saving directly *.flv to /stream directory and converted to *.mp4 as we click on “Stop Recording” button and this .mp4 file is saved to /hibernate dir. But in case I closed recording application (applet) by close button (Upper right corner) then only *.fly file exist in “/stream” folder and no conversion process happened (*.mp4) so no *.mp4 file created in /hibernate folder. Actually *.flv file are more in size then than *.mp4 (What I observed) . If suppose for same recording *.flv is 10MB the corresponding *.mp4 will be around 2MB.

This is the day I need to say sorry twice in a single day for the information I provided to Maxim.. ☹ Actually I am not facing any error. I just want to confirm the behavior of the application in below scenario. I am in testing the recording feature on 4.0.0 version of OM. And my scenario is: 1. I downloaded recording applet. 2. Now click on “Start Recording” and started recording from conference type room. 3. Now normally we click the “Stop Recording” to stop recording. 4. But there may a situation that the application crashed (applet) or by mistaken Close button is clicked. So in that cases recording is stopped but may be some functions those should be executed after “Stop Recording” click event , not executed as recording is stopped by different way. So in this case the recording will be processed (conversion from .wav to mp4) normally or application will behave some different manner.
