20150910 07:00:13 <elect> hi
20150910 07:31:40 * jvanek (jvanek@anon) has joined #jogamp
20150910 08:32:47 <xranby> monsieur_max: hi, i did not expect any lag issues with sound enabled because that is what we usually test
20150910 08:33:04 <xranby> monsieur_max: thus i kind of expected that maybe we had lag issues with sound disabled
20150910 08:33:18 <xranby> but as you said, you see lag issues regardless
20150910 08:33:26 <xranby> which is unfortunate
20150910 08:33:33 <xranby> and needs to be investigated
20150910 08:33:58 <xranby> OS? + graphics card? + GPU driver ? + Windo manager ?
20150910 08:34:08 <xranby> move file format?
20150910 08:34:23 <xranby> elect: the driving went well
20150910 08:34:28 <xranby> back and alive and happy etc
20150910 08:34:44 <elect> why so much driving, if I may ask
20150910 08:35:04 <xranby> work doing well
20150910 08:35:17 <xranby> causes new installations
20150910 08:35:26 <elect> cant do it remotely?
20150910 08:35:29 <xranby> on swedish laboratory hospitals
20150910 08:36:05 <monsieur_max> os : win + linux , cards : ati , nvidia ( gtx 970 ) , driver official in every cases, newt
20150910 08:36:11 <monsieur_max> and file is webm
20150910 08:36:15 <xranby> well.. no, not in situations when there is a clause in the contract saying that the devices must be setup and ready for testing on a certain date
20150910 08:36:27 <monsieur_max> xranby: i can upload you the video if you want to try by yourself
20150910 08:36:42 <xranby> monsieur_max: when to the lags happen?
20150910 08:36:45 <elect> ah
20150910 08:37:20 <xranby> when do...
20150910 08:37:29 <xranby> monsieur_max: yes please
20150910 08:38:05 <monsieur_max> xranby: it's quite visible at teh beginning where there's a big panning
20150910 08:38:09 <monsieur_max> ok hold on
20150910 08:38:31 <xranby> it would be interesting to see how this video is packed
20150910 08:38:42 <xranby> if there is many I, P or B frames
20150910 08:38:58 <xranby> I frames is full image in one frame, p frame uses the past image
20150910 08:39:07 <xranby> and B frames uses both the past and a future frame
20150910 08:40:00 <xranby> thus stuttering may occour if there is a lot of B frames without the frames it depend on have been processed
20150910 08:40:31 <xranby> audo frames are interleaved between the image frames
20150910 10:17:44 <xranby> http://dranger.com/ffmpeg/tutorial05.html this page describe How Video Syncs , PTS and DTS, I P and B frames
20150910 10:18:47 <xranby> the above tutorial have been updated to 2015 libav/ffmpeg api and syncing strategies
20150910 10:19:11 <xranby> thus a worth read for anyone interested in video player internals

20150910 14:46:22 <gouessej> hi
20150910 14:46:31 <gouessej> xranby: I have some questions for you
20150910 14:47:12 <gouessej> xranby: Does the JVM start noticeably faster with the compact1 profile?
20150910 14:48:53 <gouessej> xranby: When you don't use JARs, is the startup measurably fast on a Raspberry 2?
20150910 14:49:12 <gouessej> xranby: What are the other options to reduce the startup time?
20150910 14:51:40 <gouessej> xranby: I plan to use one of these packages to feed my tool and support ARM https://github.com/libgdx/packr/issues/35#issuecomment-135903158 Is it a good idea?
