Is bbb-recording-exporter compatible with BBB 2.6 and Greenlight 3.02??

[tecnomaster]

Hi @danielpetri1,

I hope you are fine.

Is bbb-recording-exporter compatible with BBB 2.6 and Greenlight 3.02??

I ask that because it looks like there are a lot of changes from BBB 2.3 and Greenlight 2.X.

If your answer is yes, excelent and thanks, I will install it.

If your answer is not, Are you planning to update it? When?

Thanks in advance for your very appreciated support on this matter.

No its not, the new included video format in 2.6 does everything but embeded chat in the mp4, and works great in greenlight some are looking to add chat as well in the video, but nothing planned.
is chat embeded important to you?

[tecnomaster]

Hi @hostbbb and thanks for your answer.

My problem is that, if you see the BBB 2.6 documentation at:
https://docs.bigbluebutton.org/administration/customize/#enable-generating-mp4-h264-video-output

It talks about 3 files located at:
/usr/local/bigbluebutton/core/scripts/

The files should be:

• video.yml
• presentation.yml
• screenshare.yml

However, the only file that I found there is presentation.yml where I uncommented (deleted the #) the "- mp4" option under video_formats, to have:

video_formats:
  - webm
  - mp4

Then I restarted BBB using:

sudo bbb-conf --restart

However, I don't see any change at the presentation or where is the mp4 file to be downloaded.

Could you tell me:

What I'm doing wrong?
Why I my BBB 2.6 doesn't have the video.yml and screenshare.yml files there?

Thanks in advance for your very appreciated support on this matter.

Hummm it looks like I just missed what is said at:
https://docs.bigbluebutton.org/administration/customize/#install-additional-recording-processing-formats

If I understand well, I first need to:

sudo apt-get install bbb-playback-video

and the follow the steps there.

Am I right?

[tecnomaster]

Ok. I got it. I will explain here the procedure so that anyone could do that:

Please read:
https://docs.bigbluebutton.org/administration/customize/#install-additional-recording-processing-formats

1. Install the required packages for new recordings formats:

sudo apt-get install bbb-playback-video
sudo apt-get install bbb-playback-notes
sudo apt-get install bbb-playback-screenshare
sudo apt-get install bbb-playback-podcast

Then, go into the right directory:

cd /usr/local/bigbluebutton/core/scripts/

and chmod 755 the new yml files:

chmod 755 video.yml
chmod 755 notes.yml
chmod 755 screenshare.yml
chmod 755 podcast.yml

Let's start with the videos. Edit the video.yml file:

nano /usr/local/bigbluebutton/core/scripts/video.yml
Uncomment at the end this:

  - mimetype: 'video/mp4'
    extension: m4v
    parameters:
      - [ '-c:v', 'copy', # Use working format codec defined in core/lib/recordandplayback/edl/video.rb
          '-c:a', 'aac', '-b:a', '128K',
          '-f', 'mp4', '-movflags', 'faststart' ]
    postprocess: []
  - mimetype: 'video/webm;codecs="vp09.00.41.08,opus"'
    extension: webm
    parameters:
      # Default single-pass encode
      #- [ '-c:v', 'libvpx-vp9', '-level', '4.1', '-b:v', '1800K', '-minrate', '900K', '-maxrate', '2610K',
      #    '-crf', '31', '-quality', 'good', '-speed', '2', '-tile-columns', '2', '-threads', '2',
      #    '-force_key_frames', 'expr:gte(t,n_forced*10)',
      #    '-c:a', 'libopus', '-b:a', '64K',
      #    '-f', 'webm' ]
      # Slower but better quality two-pass encode
      - [ '-c:v', 'libvpx-vp9', '-level', '4.1', '-b:v', '1800K', '-minrate', '900K', '-maxrate', '2610K',
          '-crf', '31', '-quality', 'good', '-pass', '1', '-speed', '4', '-tile-columns', '2', '-threads', '2',
          '-force_key_frames', 'expr:gte(t,n_forced*10)',
          '-an',
          '-f', 'webm' ]
      - [ '-c:v', 'libvpx-vp9', '-level', '4.1', '-b:v', '1800K', '-minrate', '900K', '-maxrate', '2610K',
          '-crf', '31', '-quality', 'good', '-pass', '2', '-speed', '2', '-tile-columns', '2', '-threads', '2',
          '-force_key_frames', 'expr:gte(t,n_forced*10)',
          '-c:a', 'libopus', '-b:a', '64K',
          '-f', 'webm' ]

Now the screensharing. Edit:

nano /usr/local/bigbluebutton/core/scripts/screenshare.yml
Uncomment at the end:

  - :mimetype: 'video/mp4; codecs="avc1.640028, mp4a.40.2"'
    :extension: mp4
    :parameters:
      - [ '-c:v', 'libx264', '-crf', '21', '-preset', 'medium', '-profile:v', 'high', '-level', '40', '-g', '240',
          '-c:a', 'aac', '-b:a', '96K',
          '-threads', '8', '-f', 'mp4', '-movflags', 'faststart' ]

Now, the standard presentation. Edit:

nano /usr/local/bigbluebutton/core/scripts/presentation.yml
Uncomment mp4 to be:

	video_formats:
	- webm
	- mp4

There is currently an issue where the recording formats are not automatically enabled when they are installed - see #12241 for details.

In order to enable the recording formats manually, you need to edit the file /usr/local/bigbluebutton/core/scripts/bigbluebutton.yml

cd /usr/local/bigbluebutton/core/scripts/
nano /usr/local/bigbluebutton/core/scripts/bigbluebutton.yml

and complete the following under steps:

steps:
  archive: "sanity"
  sanity: "captions"
  captions:
    - "process:presentation"
    - "process:video"
    - "process:notes"
    - "process:screenshare"
    - "process:podcast"
  "process:presentation": "publish:presentation"
  "process:video": "publish:video"
  "process:notes": "publish:notes"
  "process:screenshare": "publish:screenshare"
  "process:podcast": "publish:podcast"

Then execute:

systemctl restart bbb-rap-resque-worker.service
Go into Greelight/BBB and start a new meeting with webcam/audio, screensharing and write some notes.

Once the recording has been processed you should be able to see it like:

That's it ;-)

[hostbbb]

video_formats:
- webm
- mp4

this takes twice the disk space and is not really needed.. just use -mp4 and will play in IOS and all other browsers, the webm wont be used by players.
video_formats:
#- webm
- mp4

No its not, the new included video format in 2.6 does everything but embeded chat in the mp4, and works great in greenlight some are looking to add chat as well in the video, but nothing planned. is chat embeded important to you?

Hi @hostbbb,
Do you know any solution to have chat embedded in video with BBB 2.6?

[FSeifer]

Hello,
thank you for the instructions.
I only need the "video" format for my recordings, but currently they arent showing the used presentation..

Do I need to setup the other playback-modules as well?
e.g. "screenshare" "presentation" etc.?

Regards
FSeifer

[shurakenas]

Хорошо. Я понял. Я объясню здесь процедуру, чтобы каждый мог это сделать:

Пожалуйста, прочитайте: https://docs.bigbluebutton.org/administration/customize/#install-additional-recording-processing-formats .

1. Установите необходимые пакеты для новых форматов записей:

sudo apt-get install bbb-playback-video
sudo apt-get install bbb-playback-notes
sudo apt-get install bbb-playback-screenshare
sudo apt-get install bbb-playback-podcast

Затем перейдите в правильный каталог:

компакт-диск /usr/local/bigbluebutton/core/scripts/

и chmod 755 — новые файлы yml:

chmod 755 video.yml
chmod 755 notes.yml
chmod 755 screenshare.yml
chmod 755 podcast.yml

Начнем с видео. Отредактируйте файл video.yml:

nano /usr/local/bigbluebutton/core/scripts/video.yml Раскомментируйте в конце это:

  - mimetype: 'video/mp4'
    extension: m4v
    parameters:
      - [ '-c:v', 'copy', # Use working format codec defined in core/lib/recordandplayback/edl/video.rb
          '-c:a', 'aac', '-b:a', '128K',
          '-f', 'mp4', '-movflags', 'faststart' ]
    postprocess: []
  - mimetype: 'video/webm;codecs="vp09.00.41.08,opus"'
    extension: webm
    parameters:
      # Default single-pass encode
      #- [ '-c:v', 'libvpx-vp9', '-level', '4.1', '-b:v', '1800K', '-minrate', '900K', '-maxrate', '2610K',
      #    '-crf', '31', '-quality', 'good', '-speed', '2', '-tile-columns', '2', '-threads', '2',
      #    '-force_key_frames', 'expr:gte(t,n_forced*10)',
      #    '-c:a', 'libopus', '-b:a', '64K',
      #    '-f', 'webm' ]
      # Slower but better quality two-pass encode
      - [ '-c:v', 'libvpx-vp9', '-level', '4.1', '-b:v', '1800K', '-minrate', '900K', '-maxrate', '2610K',
          '-crf', '31', '-quality', 'good', '-pass', '1', '-speed', '4', '-tile-columns', '2', '-threads', '2',
          '-force_key_frames', 'expr:gte(t,n_forced*10)',
          '-an',
          '-f', 'webm' ]
      - [ '-c:v', 'libvpx-vp9', '-level', '4.1', '-b:v', '1800K', '-minrate', '900K', '-maxrate', '2610K',
          '-crf', '31', '-quality', 'good', '-pass', '2', '-speed', '2', '-tile-columns', '2', '-threads', '2',
          '-force_key_frames', 'expr:gte(t,n_forced*10)',
          '-c:a', 'libopus', '-b:a', '64K',
          '-f', 'webm' ]

Теперь демонстрация экрана. Редактировать:

nano /usr/local/bigbluebutton/core/scripts/screenshare.yml Раскомментируйте в конце:

  - :mimetype: 'video/mp4; codecs="avc1.640028, mp4a.40.2"'
    :extension: mp4
    :parameters:
      - [ '-c:v', 'libx264', '-crf', '21', '-preset', 'medium', '-profile:v', 'high', '-level', '40', '-g', '240',
          '-c:a', 'aac', '-b:a', '96K',
          '-threads', '8', '-f', 'mp4', '-movflags', 'faststart' ]

Теперь стандартное изложение. Редактировать:

nano /usr/local/bigbluebutton/core/scripts/presentation.yml Раскомментируйте mp4 так:

	video_formats:
	- webm
	- mp4

В настоящее время существует проблема, из-за которой форматы записи не включаются автоматически при их установке — подробности см. в #12241 .

Чтобы включить форматы записи вручную, необходимо отредактировать файл /usr/local/bigbluebutton/core/scripts/bigbluebutton.yml.

cd /usr/local/bigbluebutton/core/scripts/
nano /usr/local/bigbluebutton/core/scripts/bigbluebutton.yml

и выполните следующие шаги:

steps:
  archive: "sanity"
  sanity: "captions"
  captions:
    - "process:presentation"
    - "process:video"
    - "process:notes"
    - "process:screenshare"
    - "process:podcast"
  "process:presentation": "publish:presentation"
  "process:video": "publish:video"
  "process:notes": "publish:notes"
  "process:screenshare": "publish:screenshare"
  "process:podcast": "publish:podcast"

Затем выполните:

systemctl restart bbb-rap-resque-worker.service Зайдите в Greelight/BBB и начните новую встречу с веб-камерой/аудио, демонстрацией экрана и напишите несколько заметок.

После обработки записи вы сможете увидеть ее следующим образом:

Вот и все ;-)

The video opens but there is still no "Download" button. Tell me how can I download a video file?

[morexzamani]

Hi guys
First, thanks @tecnomaster for his notes.
But there are some issues yet! I need your help.

These solutions use the native packages and docs of BigBlueButton and are not related to the bbb-recording-exporter script!

If I use bbb-recording-exporter:

1. I must rebuild my meeting manually to show the video output format in the Greenlight. How can it be automatically?
2. The annotations of whiteboard are not present in output video :(
3. There isn't a download button for users to archive the MP4 output.

If I use native BigBlueButton solution:

1. Chats are not contained in the MP4 video output!
2. There isn't a download button for users to archive the MP4 output.

@shurakenas and @tecnomaster, have you found any solution for them? Or do you know another repositories to work well with BigBlueButton v3.0.13 to have the ability to download session recordings?

[shurakenas]

Привет, ребята. Во-первых, спасибо.@tecnomasterдля его заметок. Но есть ещё несколько проблем! Мне нужна ваша помощь.

Эти решения используют собственные пакеты и документацию BigBlueButton и не связаны со bbb-recording-exporterскриптом!

Если я использую bbb-recording-exporter:

1. Мне нужно rebuildвручную настроить videoформат вывода для встречи в Greenlight. Как это сделать автоматически?
2. Аннотации доски не присутствуют в выходном видео :(
3. Кнопки загрузки для архивирования выходного файла MP4 у пользователей нет.

Если я использую нативное решение BigBlueButton: 3. Чаты не содержатся в выходном видео MP4! 4. Нет кнопки загрузки, позволяющей пользователям архивировать выходной MP4.

@shurakenasи@tecnomaster, нашли ли вы какое-нибудь решение? Или знаете другие репозитории, которые хорошо работают с BigBlueButton v3.0.13, чтобы можно было загружать записи сессий?

Click video, in the video that opens, right-click in the video area, Save the video as
