Hi, Ed!

Hope you're doing well by doing good, and staying healthy while you're at
it.

I just installed wxcam and get a warning message when I start it; see
attached.

I'll try to find the proper ffmpeg command line syntax to test my webcam.

Regards,

Rich

Ben,

It is the recording that has precedence over the streaming. I need to look
deeply into what FCC provides for webinars, but I'll probably want to record
the speach and slides for a webinar and view them to understand how it comes
across to attendees. I don't know that live streaming would be useful in
developing business.


As an example, if you were looking to create a tutorial where you walk
through using an application on your computer as you narrate what you are
doing, OBS is a very good solution since it can combine a video feed of
your desktop with a video feed of your face (webcam). Either live, through
a streaming server or recorded to a file on your hard drive for sharing
later. Works well on Slackware which is nice.


I'll make time to view the 5+ hour master course in using OBS. And of course
it works well on Slackware. :-) Most things do, including me.

Thanks for the useful insights.

Stay healthy,

Rich

It helps to know what you are looking to accomplish. OBS is interesting
since it can be used to either record or stream. It also mixes audio/video
sources so it's useful for podcasting applications. For a communication
tool then your search will probably take you in a very different direction.

As an example, if you were looking to create a tutorial where you walk
through using an application on your computer as you narrate what you are
doing, OBS is a very good solution since it can combine a video feed of
your desktop with a video feed of your face (webcam). Either live, through

Alexander,

I installed it and looked at the introductory video for the Master Class.
Looks really good.

I need to better understand which software is better for recording from the
camera and which is better for displaying what's on the screen here. I don't
know that I'll do any streaming.

Since I'm new to all this I need to learn terminology, software, file
formats, and what I don't know that I need to know (Rumfield's
unknown-unknowns).

All suggestions and pointers to resources is very welcome.

Thanks,

Rich

As a possible alternative, I've been using OBS Studio for webcam recording,
in addition to streaming and recording some games, and it's worked pretty
well for me in that role, and that's available for Linux.

Ed,

Yep, there were 48 dependencies not installed here. Took a while to get them
installed but vlc did build. Looks like it needs a detailed user guide.


webcamoid looks interesting, I'll have to check it out.


The UI when it's loaded is quite distracting. Cute, but distracting.

I'll look at that, too.

What I want to do first is in the 'screen capture' category rather than the
'webcam capture' category. I use impressive to present the beamer PDFs in my
presentations and I need to learn how to display the pdf 'slides' using
impressive during a webinar. Attendees can see it full screen (I'll be
speaking, too) and I will have it in a window within the webinar hosting
software. Much to learn and now's the time to learn it.

Stay well,

I've used VLC before.  Its a swiss army knife for video playback with
capture capability.  Crazy big dependency list.  It may be a bit
overkill if all you what is a simple webcam software.

webcamoid looks interesting, I'll have to check it out.

wxcam on Slackbuilds,org. VERY minimal and few bells and whistles.  I
might drop it when Slackware current -> 15.0 in favor of maybe webcamoid.

For the crusty command line crowd, ffmpeg will also capture, see
https://trac.ffmpeg.org/wiki/Capture/Webcam

QT4 and QT5 have test utilities, "QT V4L2 Test Utility" and "QT V4L2
capture utility"

[PLUG] Webcam capture software

[Rich Shepard]

My research found two linux applications for webcam capture: vlc and
webcamoid. Has anyone experience with these and will share thoughts on
preferring one ove the other?

TIA,
