Tizen Developers

You can Capture Screenshots of Gear S3 by:

Pressing the Home key and swiping from the left of the screen to the right.

http://www.samsung.com/ca/support/skp/faq/1119830

But, I haven't seen any procedure of screen recording yet.

Check your Watch:

/usr/bin/screen_recorder

Ask S.msung why you need ROOT for this...

enlightenment_info -dump_topvwins /opt/usr/home/owner/media/Images

This is how I was able to capture screens on Tizen 3 and 4... also root only...

Best Regards

sh-3.2$ screen_recorder -f RGB4 -c 1 -o 360,360 -p 30 -b 1000000 -t Video -m 0
It's a console application
++ capture = Still
++ format = RGB4
++ output size(width,height) = 360,360
++ fps = 30
++ bitrate = 1000000
++ filepath = Video

No idea why...

But I am not able to capture Videos in Tizen 3...

Gear S3 creates 0 Byte files... and SM-Z400 saves only 1 KB Header... or it crashes and device reboot...

screen_recorder -f AR24 -o 360,360 -m 0 -t /tmp/videoAR24

screen_recorder -f XR24 -o 360,360 -m 0 -t /tmp/videoXR24

?

Security?

Best Regards

Hmmm...

Maybe something else work... Found in Google... because screen_recorder shows something like this:

(screen_recorder:3352): GStreamer-CRITICAL **: gst_mini_object_unref: assertion 'mini_object->refcount > 0' failed
last_error(32) code(0) id(0)

https://stackoverflow.com/questions/49270207/how-to-record-audio-and-video-in-gstreamer

My output on my SM-R760...

sh-3.2# gst-launch-1.0 -e v4l2src ! queue ! x264enc ! h264parse ! queue ! qtmux0. alsasrc ! 'audio/x-raw,rate=44100,depth=24' ! audioconvert ! audioresample ! voaacenc ! aacparse ! qtmux ! filesink lo
cation=test.mp4
WARNING: erroneous pipeline: no element "v4l2src"

Maybe someone else can find correct settings faster...

100 years later I found this... as all my other attempts failed... durig F&ing not existing documentations...

No idea if someone will share better solution... as it seems again "Top Secret"... like all in Tizen...
