RPI Processing Video

i play with the spec. video lib for Raspberry Pi and Processing and could not play any video
( while video capture worked ) so i suspected the GStreamer thing used from it.

now i see also at forum same question:
https://discourse.processing.org/t/glvideo-not-working-on-pi-4-running-processing-3-5-3/13661
and start digging.

https://pi.processing.org/libraries/
https://github.com/gohai/processing-glvideo

also check local with

dpkg -l | grep gstreamer1


shows on a updated RASPBIAN BUSTER
are rev GSTreamer installed 1.14 ( one time 1.15 )
( while @gohai talks about a rev 1.12 provided in his library )



0.0 new install:
https://downloads.raspberrypi.org/raspbian_full_latest
burn with etcher to a >= 8GB uSD card
( best like SunDisk Ultra A1 (U1) 16GB while the much more expensive (U3) cards for video recommended,
it is not verified RPI 1 ..3 can perform ( USB2 card reader? )
for RPI4 i have no info regarding this, i know it has USB3, but for the uSD card reader too?


0.1 new Processing install

curl https://processing.org/download/install-arm.sh | sudo sh




0.2 new video lib install ( via contribution manager )
first:
+ set RPI to

sudo raspi-config


/ 5 interfacing options
// P1 camera / enable

/ 7 advanced options
( NOT NEED TO DO or UNDO )// A7 GL Driver Legacy == disabled )
//A3 MEMORY SPLIT / 128

Processing IDE / Tools / add Tool... / Libraries / GL Video // 1.3 Gottfried Haider
test examples
video ( get white video window , on mouse click and wait get timeout error )
and capture ( should work if camera installed )


1.0 now i try to build that video thing again:
..your sketchbook Processing/libraries/glvideo/library/

cp building-gstreamer.txt building-gstreamer.sh



chmod +x building-gstreamer.sh



nano building-gstreamer.sh


// first line copy [ctrl][k][ctrl][u]
first line disable with #
copy line change
/ aptitude / apt -y /
save [ctrl][o][ctrl][x]

./building-gstreamer.sh


( an hour ( on the RPI3B+ hardware ) of running info though the terminal )

restart Processing
but no change, ( so actually what should i expect to be new? )
check on
/glvideo/library/glvideo.jar
is still the old one.


now i delete the new subdirs again ( was wrong, but this is my bLOG, not a MANUAL )
/orc
and
/patchelf
but esp. the original / resulting
/linux-armv6hf

and run the build again to see if it is now recreated??
GRRR
mkdir: cannot create directory ‘/home/pi/linux-armv6hf’: File exists


2.0 ok now i copy that directory ( created by the first build ) back to
/libraries/glvideo/library/linux-armv6hf ( what i deleted above )
and test processing again
NOT LUCKY

i see that possibly less than half the files only where created by that build, no idea what is wrong with my setup or buildfile...


3.0 please, i know that is the most bad hack i ever tried,
but i use that resulting ( incomplete ) home/pi/linux-armv6hf content:
* new install library
* verify same problem
* copy the new build files into / over

and restart the processing sketch:

WOW, it worked???

* i will put the zip of the new files here, but the hack is too bad, you can try to copy that new files into.
this i verify insofar as i download and copy into the prior also checked other RASPBIAN stretch uSD.
( and only tested with that one example "SingleVideo" but works here too)

* also if you follow this build procedure, it changes your system, so make sure you work on a extra uSD system setup



update,
with 2019-09-26-raspbian-buster-full.zip
release_notes

GL video 1.3
video and camera not work anymore!

while updating my "old"&"repaired" system, no problem, still all works.

not try a build on the new one up to now, but want test
https://github.com/processing/processing-video/releases/tag/r6-v2.0-beta4

ok, after deleting video and GLvideo library i unzip
r6-v2.0-beta4/video-2.0-beta4.zip
( as video )
and play movie and RPI camera OK



while that was good news, sure i try that same lib on my old system
and a-- it not found the camera and -b- had error on play video.
