While I am not a lawyer, my understanding is that if you use parts of LGPL-ed code(as source, not external library), you should open-source your application.

Unless you have permission from the copyright holders, of course.

Well, last 20 minutes or so I was reading through LGPL and I didn't see such clause, but again, I am not a lawyer. And even if LGPL allows that I highly doubt that is the case with abc and blessn900.

Remember, copyright holders are free to do with their code whatever they want, including giving permission or relicensing as they see fit.

That's entirely another matter :D
And I'm sure that, once informed, the copyright holders (Felipe or Nokia or both) will deal properly with this issue.

What should I do? Anyone can help me?
Thanks.

Your /root/ directory is probably full.
Try this:

Code:

gst-launch-0.10 -v v4l2camsrc device=/dev/video0 ! video/x-raw-yuv,width=1280, height=720!dspmp4venc !avimux!filesink location=/home/user/MyDocs/test.avi

OK, if you say so, I am not knowledgeable enough on the matter to argue :D

TBH I don't want some kind of license war, would prefer to play it gently, i.e. those who have the software purchased/installed to ask the author for the source code. But if there is no development in a week or so, I will inform Felipe, judging from his blog and other sources he will not leave the things as they are ;).

contents of lib/dsp goes to /lib/dsp
contents of usr/lib goes to /usr/lib

Thanks freemangordon, this really helped. Now ABC is functional again.

Re: [HOWTO]Watch 720p videos on n900 [09.12.2011 VIDEOCALL WORKS]

Any reason to upgrade to the newer libgstdsp if you dont use ABC?

new libgstdsp is in no way related to abc, you can upgrade if you wish, it has several fixes compared to current one, but better wait until I finally make up my mind and decide how to distribute all this stuff.

Re: [HOWTO]Watch 720p videos on n900 [09.12.2011 VIDEOCALL WORKS]

installed latest libgstdsp..this file is related to image quality for pictures right?..when i capture a picture with the cam, then go to image viewer, see details and the image quality always show 85,5%..is this normal?..thought the debate was between 95 and 100%..so i am kind of disapointed..or is just an image viewer bug?

No. Also the "latest" is on the first page, the library i've attached a few posts ago was intended as a test whether it fixes the problem with ABC. When there is a new release I will announce it here.
