Bug in aio-grab ?

Hi everybody

i think there is a bug in aio-grab

if you set A/V setting in the follow mode:

Video Output: DVI
Mode :1080i
Refresh: 50Hz
Display 4:3 content as : Pan&Scan
Display >16:9 content as : Letterbox

and you try to grab a video screenshot an error occour

	Source code
1 2 3 4 5 6 7	root@dm800:~# grab -v -r 720 -j 80 AiO Dreambox Screengrabber v0.81 Detected STB: Brcm7401 Grabbing Video ... Bus error root@dm800:~#

same problem with v0.81 and v0.83

If you change Pan&Scan in Pillarbox, grab work fine

any Idea?

probably too less memory, try it with a swapfile enabled

Hi Gutemine
I found this problem on a dm800 PVR, i couldn't test on a 8000 or 7025 because i don't have a Box

I use Ghost git repo, and i found the problem on a pure CVS and on my image, i don't think is a memory problem, there was 50Mb free and 64Mb on swap during the test.
Could you try to test on your dream?

I can not test it on my 7025 either, but the same Bus Error was reportet when people tested my screensaver dameon on 800s which is also based on the latest grab AiO code

The problem was not reported on 8000s

Ciao

Aio was written by Seddi and not DMM, so you are waiting in the wrong queue :-)

So just tried to reproduce the error here. I cant reproduce on my 8k, and I cant reproduce on my 800. But my 800 works with an older
software version at the moment, didnt update for a long time

Hmm ... "Bus Error" at this stage means we cant access the decoder memory, mostly its an alignment failure means the decoder chip doesnt
report us the right memory address where the actual image is stored. So at this point there is nothing wrong inside the sourcecode. The address
is always accessed the same way, so if there is a bug in the source it should not work with "pillarbox" as well. Maybe there is a bug inside the
driver. So I will test again when I updated my 800 in the next days. Maybe I can reproduce the error there.
