In order to provide support it is required the logs of media serve during the period of time where files are recorded

Logs can be found in /var/log/kurento

We have been making some tests and our recommendation for you is to record using WEBM format and later post-process and transcode the media to the format you want. Recording needs to take place in live mode and some MP4 players don't like the container format required for that. Using WEBM in combination with a post-processing step (for which you can use ffmpeg) is probably your best option for avoiding such type of incompatibilities.

Close this item due to inactivity.

Dear FIWARE coach,
we forward you an update request received from a CreatiFI applicant we are
not able to solve.
Please let us know if you need direct contact with the submitter.
Thanks.

**********************************

Previously, we've been trying to use kurento server to record a webcam
videos in browser, save them on the server as mp4 files and send them to
our video processing backend.

Kurento uses webm as a default but that extension is not supported by
Windows Media Services (used by our backend) so we were forced to try to
use a mp4 saving format.

First attempt ended up with empty files generated by Kurento. After few
issues created and few discussions on github and [tutaj nazywa tego serwisu
do zgłaszania usterek w kurento] we have been told, that it's a common
issue when kurento is configured to use mp4 and we should change it to webm.

We have tried that recently but that issue is still there - kurento
produces empty, 0 byte webm files which are obviously corrupted and are not
able to be processed by ffmpeg nor Windows Media Services.

Basically this is the "status report" on the solution that FIWARE expert
has been provided to us before: "We have been making some tests and our
recommendation for you is to record using WEBM format and later
post-process and transcode the media to the format you want. Recording
needs to take place in live mode and some MP4 players don't like the
container format required for that. Using WEBM in combination with a
post-processing step (for which you can use ffmpeg) is probably your best
option for avoiding such type of incompatibilities."

However, even after changing the video format to webm as it has been
suggested to us – the 0-file-size problem persists.
The question is then - is there anything else that can be done about it?

We have tested again and WebM recording is working perfectly on the media server. You probably have some kind of issue in your application. If you want to receive useful help, you should provide more useful diagnose information. In particular, (I already asked for this without success) the following

1. Clean logs of your media server while reproducing the problem. For obtaining clean logs, stop your media server first, remove all previous logs, and re-start the media server again.
sudo service kurento-media-server stop
remove log files in /var/log/kurento*
sudo service kurento-media-server start
execute your application and make it fail
send us the log

2. Full information on your media server version. For this, execute
kurento-media-server -v
and send us the result

3. Your source code. We are not supporting coffee script. You hould provide us your application code in JavaScript or Java if you want us to be able to help you.

4. A precise description of what you want to do in your application. For example, RecorderEndpoint is configured by default for recording both audio and video. If you try to record only video with default configuration, RecorderEndpoint will block waiting for the audio without droping anything into the target file.

Best regards.

Dear FIWARE coach,
we received an updated from a CreatiFI applicants.
CreatiFI phase 1 finishes on 15th of July.
The developer needs an answer asap.
Could you provide some hints?
Thanks in advance.

Here are the details:

1. Logs:

4. We're trying to record audio and video using webRTC recorder (and save
it to webm). It was recording files pretty well for a few times when we
started working on it but, after some time, it stoped. Without making any
changes to the JS code. It's apparently an issue with the backend

Hi,

Try to upgrade to the latest stable version of KMS. Do (in your KMS machine) the following:
sudo apt-get update
sudo apt-get upgrade

If this does not solve the problem, your only option is to migrate to KMS v 6.0, but this requires some more extra work given that you need to support trickle ice.

You can find and example of recorder/player supporting trickle ice here (browser code):
https://github.com/Kurento/kurento-tutorial-js/tree/master/kurento-recorder

Best regards.

We didn't receive further comments on this. We close the issue.

Dear FIWARE coach,
we forward you an update request received from a CreatiFI applicant we are
not able to solve.
Please let us know if you need direct contact with the submitter.
Thanks.

Dear,
we have upgraded kurento to 6.0.1 and used the js client recorder you
provided above but our setup is still broken.

ALL the files (both in webm and mp4 format) have 382 bytes of size and
ffmpeg says they are corrupted (so we can't use them). Kurento log for each
recording session looks like that:

Dear,
sorry, but we re-submitted a ticket on 30th of July, but up to now no
feedback.
The CreatiFI applicants need ASAP some feedback in order to fix him issues.
Can you reply to us something asap, please?

Hi,
Sorry for the late reply. Most of the Kurento team takes holidays during the first two weeks of August.

In relation to your request, we have validated the RecorderEndpoint capability in KMS v6.0.1 and, in our tests, everything seems to be working correctly. In the Kurento public mailing list nobody is reporting such type of problems after KMS v 6.0.1. On the other hand, we have possitive reports of having MP4 format working correctly now. This makes us think that there may be some type of problem with your application or with the way in which you are trying to use/configure Kurento Media Server. In order to unblock the situation, I suggest the following:

1. Please, share with us your application code as well as build/deploy/execution instructions so that we can reproduce the problem in our testbeds.
2. If this is not possible, we may need to use a more agile communication channel such as Skype or equivant, so that we can discuss with you in real-time what you are doing.

Let us know which of the options you prefer.

Dear,
the applicant did a skype call with Prof. Luis Lopez, the Kurento GE
expert, and the issue has been fixed.
Thxs to Prof. Luis Lopez.

You can close the ticket.

BR
