** ok, let's try what
|
||||||
|
let's try default video out after i turn on the screen sharing from cl part
|
||||||
|
|
||||||
|
with code cleaned up i can start the share, that's nice
|
||||||
|
|
||||||
|
gst-launch-1.0 pipewiresrc path=90 ! videoconvert ! autovideosink
|
||||||
|
|
||||||
|
let's also try to add opengl processing
|
||||||
|
gst-launch-1.0 pipewiresrc path=90 ! videoconvert ! gltransformation rotation-z=45 ! glimagesink
|
||||||
|
|
||||||
|
so, this kind of works
|
||||||
|
gst-launch-1.0 pipewiresrc path=90 ! videoconvert ! capsfilter caps="video/x-raw,format=RGBA" ! glupload ! gltransformation rotation-z=45 ! glimagesink
|
||||||
|
|
||||||
|
even if the thing is small
|
||||||
|
|
||||||
|
** trying to figure out why gl things open a small window
|
||||||
|
*** one that works
|
||||||
|
GST_DEBUG=4,caps:5 gst-launch-1.0 pipewiresrc path=90 ! videoconvert ! autovideosink
|
||||||
|
has
|
||||||
|
deterministic way of creating a stream-id

|

|
|
||||||
|
well, i guess i can just open the window full size
|
||||||
|
|
||||||
|
*** ok! looks like it does stream full resolution.
|
||||||
|
now. i'd want to open the displaying pipeline programmatically
|
||||||
|
and then maybe try to dynamically change params
|
||||||
|
|
||||||
|
i guess even without a window embedding, just starting a window is good enough
|
||||||
|
but also, hm.
|
||||||
|
|
||||||
|
do i need any ui for the video window? i really don't think so.
|
||||||
|
maybe let's figure out the missing cursor
|
||||||
|
gst-launch-1.0 pipewiresrc path=90 ! videoconvert ! capsfilter caps="video/x-raw,format=RGBA" ! glupload ! gltransformation rotation-x=-15 ortho=True ! glimagesink
|
||||||
|
gst-launch-1.0 gltestsrc ! gltransformation rotation-x=-45 ortho=True ! glimagesink
|
||||||
|
|
||||||
|
|
||||||
|
** am i not getting into Create Session? after the Start?
|
||||||

|
||||||
|
(also note that here are cursor options)
|
||||||
|
|
||||||
|
** ok, let's try writing this in java then
