07:46 nongio hi there is someone?

07:50 kylemcd hi
07:55 kylemcd hey nongio
07:56 nongio hi, I'm looking at some bugs on the issues list on github
07:56 kylemcd cool
07:56 kylemcd is there something you're looking for? or just want to help?
07:56 nongio just help...
07:57 kylemcd great!
07:57 nongio i've commented this one: https://github.com/openframewo​rks/openFrameworks/issues/2395
07:58 nongio seems to me that is a windows only bug, right?
07:58 nongio i've made a video with timecode to test
08:00 satoruhiga joined #openframeworks
08:05 kylemcd ah nice
08:05 kylemcd that's super helpful
08:06 kylemcd yes it does look like a windows only bug, i'll tag it
08:06 nongio good
08:07 kylemcd some good issues to look at are the oldest ones
08:07 kylemcd https://github.com/openframeworks/openFramework​s/issues?direction=asc&labels=&mileston​e=&page=1&sort=created&state=open
08:07 kylemcd also a great way to contribute would be by helping with the documentation -- a lot of it is empty right now
08:07 kylemcd https://github.com/openframeworks/ofSite
08:08 kylemcd it's a bunch of plain text markdown files like this:
08:08 kylemcd https://github.com/openframeworks/ofSite/blo​b/master/_documentation/gl/ofShader.markdown
08:08 nongio about the documentation I think that i'm not the right person…
08:09 nongio i can try but my english is not perfect

10:06 nongio is there any android open framework developer? I want to know the status of gles2 on android
10:14 Hurtzy joined #openframeworks
10:38 achim joined #openframeworks
10:50 nongio joined #openframeworks
10:52 admsyn nongio: yes android is supported by oF, and there's a few developers working on it
10:53 admsyn do you mean in the channel right now?
10:53 nongio yes sorry
10:54 admsyn I'm pretty sure with 0.8.0 we've got gles2, but I might just be confusing it with iOS (which does)
10:54 julapy joined #openframeworks
10:54 admsyn julapy: do you happen to know the status of gles2 on android?
10:54 admsyn :)
10:55 nongio yes I know about the iOS support...
10:56 admsyn I'll ask arturo in a sec :)
10:57 admsyn arturo says gles2 and 3 are supported on android
11:00 nongio thanks

11:43 bastidererste joined #openframeworks
11:44 asper joined #openframeworks
11:44 bastidererste back again... does ofPtr<ofQTKitGrabber> have a function to embed text into video?
11:45 bastidererste or how would i create an overlay like a logo and save it to disk?
11:57 admsyn so you want to render some text onto a video in a video grabber, and render that out to a file?
11:58 bastidererste yep...
12:00 admsyn I'm not sure if that's built in, might have to read each frame out to something like an ofPixels, then render it out with ofQTKitMovieRenderer
12:00 bastidererste ah, thats a good idea...
12:07 asper joined #openframeworks
12:11 bastidererste hmm... ffmpeg can do hard embed subtitles on the fly with a terminal command... i guess that's easier

16:50 dantheman_ loooooook good
16:53 jvcleave dantheman_ nice!
16:56 jvcleave going to implement recording next
17:02 dantheman_ not if I beat you to it
17:02 dantheman_ I'm trying to do that today
17:03 jvcleave cool - go for it :)
17:23 superFluid joined #openframeworks

17:48 dantheman_ jvcleave: this looks like an OK path to ffmpeg https://github.com/timscaffidi/ofxVideoRecorder
18:06 jvcleave nah - you wanna use OMX
18:08 jvcleave the raspvid app has an implementation but it uses MMAL - I would start by looking at that and porting it
18:09 dantheman_ raspvid
18:09 dantheman_ kk
18:09 dantheman_ where is the raspvid source?
18:10 dantheman_ https://github.com/raspberrypi/use​rland/blob/master/host_application​s/linux/apps/raspicam/RaspiVid.c?
18:10 jvcleave actually I did an MMAL//OF camera app that I need to publish
18:10 jvcleave but usually it is in rpi/firmware
18:10 dantheman_ gotcha
18:10 dantheman_ the userland
18:11 dantheman_ lol
18:11 dantheman_ I forgot how looking at real embedded code makes me wanna bang my head against the wall
18:11 dantheman_ well this isn't that bad
18:15 vade joined #openframeworks
18:17 asper joined #openframeworks
18:21 jvcleave actually it is here
18:21 jvcleave https://github.com/raspberrypi/userland/t​ree/7542fb5fb6bc9370b3a2d235cee64ee781c42​c61/host_applications/linux/apps/raspicam
18:22 jvcleave if you are just writing a recording app it may be easier just to control the raspivid binary - I am sure someone has probably written a python bridge
18:23 jvcleave the OF stuff will be more about textures, video in an app/controlling with OF
18:27 dantheman_ I want the textures
18:27 dantheman_ lol
18:29 dantheman_ args
18:30 dantheman_ you didn't mirror video grabber with the omxGrabber did you?
18:30 dantheman_ so there is no way to get the texture?
18:30 dantheman_ or the pixelRef
18:30 jvcleave it has textures
18:31 jvcleave mine does that is
18:31 dantheman_ really?
18:31 jvcleave raspivid doesnt
18:31 dantheman_ https://github.com/fakelove/omxCameraApp/b​lob/develop/addons/ofxOMXVideoGrabber.cpp
18:31 dantheman_ doesn;t see it
18:31 dantheman_ doesn't*
18:32 dantheman_ oh tex is just a public var
18:32 jvcleave omxVideoGrabber.tex is public - a little YOLO but you are a responsible person :)
18:33 jvcleave but yeah - I will put in a getTextureReference once I straighten it up
18:34 dantheman_ yer
18:34 dantheman_ lol
18:34 dantheman_ and a getPixelRef
18:34 dantheman_ but its all textures right
18:34 dantheman_ cause it is pulling them out of the GPU
18:35 jvcleave right - pixels are'nt that important
18:35 dantheman_ well maybe? if I'm doing openCV stuff
18:35 dantheman_ right?
18:35 dantheman_ cause you gotta get it all the way to a CVImage
18:36 jvcleave yeah - but you can readToPixels yourself currently - gonna be slow
18:37 dantheman_ yah
18:37 jvcleave omx has some crazy shit with face detection if that is what you are thinking
18:38 jvcleave search for face on this page - I don't know if the camera chip supports it http://www.jvcref.com/files/PI/doc​umentation/ilcomponents/prop.html
18:40 jvcleave Face Recognition Database File, Face Recognition Face Learning - wild
18:40 dantheman_ jvcleave: I'm just like playing
18:40 dantheman_ got a client stuff I'm thinking of trying to do with oF on the pi
18:41 dantheman_ we already have stuff working with python + rpi
18:42 jvcleave fakelove - is that you?
18:43 jvcleave nm - i see your name in the commit
18:43 dantheman_ yah that is new day jbo
18:44 dantheman_ job*
18:44 dantheman_ i'm trying out this ffmpeg stuff
18:44 dantheman_ see how it works
18:44 jvcleave yeah - I am curious if it is fast enough
18:44 dantheman_ http://fakelove.tv/
18:44 dantheman_ new day jorb
18:44 dantheman_ them made me full time
18:46 jvcleave nice!
18:49 jvcleave vade: I was curious if you saw this http://www.snappylabs.com/blog/snappy​cam/2013/07/31/iphone-king-of-speed/
18:50 dantheman_ jvcleave: that is nice
18:51 jvcleave yeah - it was interesting how they found the speed on the CPU

20:29 dantheman__ hmm
20:29 dantheman__ looks like this might not be fast enough
20:29 dantheman__ jvcleave: ^^
20:41 dantheman_ joined #openframeworks
21:01 dantheman_ jvcleave: how far along are you with the capture stuff
21:01 dantheman_ cause I don't think ffmpeg is gonna be fast enough

22:01 laserpilot joined #openframeworks
22:45 GuidovanPossum joined #openframeworks
23:04 jvcleave dantheman: haven't started any recording implementation
23:04 dantheman wordy
23:04 dantheman yeah ffmpeg is too screwy
23:04 dantheman it doesn't really work
23:04 dantheman I'm gonna have to do it the proper way
23:05 laserpilot gross
23:08 jvcleave it could be tricking - I am not sure whether it can have both textures and an encoder
23:08 jvcleave tricky
23:13 dantheman jvcleave: I would really only want the encoder
23:13 dantheman for me
23:13 dantheman atleast
23:14 dantheman idk I'm reading that the ffmpeg for raspbin isn't any good
23:15 jvcleave ffmpeg isn't great anywhere really - it's just amplified on the RPi
23:16 jvcleave I use it in ofxOMXPlayer to primariily get the codec info
23:16 jvcleave it does that really well
23:40 admsyn joined #openframeworks
23:42 dantheman yeah
23:43 dantheman i'm getting raspivid up and compiling
23:43 dantheman might just modify it for the work stuff and back port it to OF
23:43 dantheman args c
23:43 dantheman written by hardware guys
