morning folks!
17:00
Bertl
MEETING TIME!
17:00
Bertl
please /msg me if you want to report anything
17:01
vup
is here
17:06
Bertl
vup: do you want to report anything?
17:06
vup
nope, was quite busy with other stuff...
17:07
Bertl
okay, guess it will be a short meeting then
17:07
Bertl
se6astian is still on his way back to Vienna
17:07
Bertl
our intern, yasmin, is missing again, and there is not too much to report from my side
17:08
tpw_rules
my thesis is almost done so my free time is set to expand soon. i don't believe i ever got login information for the new setup vup
17:10
Bertl
okay, so I did some more tests with the Magewell PCIe device
17:10
Bertl
and it seems to work reasonably well with a small test tool written around the SDK they provide
17:11
Bertl
did some test runs with 1mio frames captured over 3 HDMI ports at the same time
17:11
Bertl
and we got about 10-20 bad frames per input under 'normal load' conditions
17:11
Bertl
mostly dropped frames but also some frames which did not pass the hash test
17:12
Bertl
I think this can be improved further by using a dedicated system instead of a desktop which is also used for many other things during captuer, but even if not, the failure rate is quite low
17:13
Bertl
(note this was already done with the 2048x1080p60 mode, so increased amount of data)
17:14
Bertl
that's it from my side for today, and if nobody else wants to report anything, also the conclusion of this short meeting
17:14
Bertl
se6astian might report more stuff when he finally arrives ...
17:17
Bertl
off for now ... bbl

thanks for taking care of the meeting bertl

quick reports from my side:
19:07
se6astian
I tested the rock pi 4 with the magewell device and after resolving an issue with the 5V lab power supply and switching to a PD usbc one the magewell works as expected
19:08
se6astian
testing actual full fps capture was hampered by the too slow nvme ssd
19:08
se6astian
benchmarks showed it cannot reach the 311MB/s combing in
19:08
se6astian
and just has comparison maxed out the CPU power of the rockpi
19:09
se6astian
so my plan now is to source a high end nvme ssd
19:09
se6astian
and benchmark that and test it on the rockpi
19:09
se6astian
beside that I improved the raw capture software tools and conversion scripts a bit here and there for raw video capture
19:10
se6astian
so signs are good that the rockpi could become a very small mobile recorder hardware platform
19:10
se6astian
thats it from my side for this week
