Failed on startup with multiple monitors (USB Monitor) #1
Comments

Could you please paste the output from $ ./ffscreencast --list |
|
I see, the problem is, that Please also dump the output of: /ffscreencast --slist --dry |
|
hey! thanks for the feedback... and sorry for my terse dump up there... I had to hit the road and thought I'd log it before i left... here's the dump from your original request: and here's the next dump: and I don't think it matters, but I'm running |
|
hey... fyi - taking a closer look at the dumps, I wonder if maybe it's because I might have grep and sed aliased in some way? I have the following: grep='grep -I --ignore-case' I'm sure you're aware, but you can force it to use the non aliased version in your scripts by preceding it with a slash, like: \grep etc... |
|
Could you also... a.) try it on a shell (possibly bash) where u don't have any aliases |
|
Can u pull the latest master code and try again. |
|
i pulled the latest and still the same issue. I also tried running it with a clean shell using the approach detailed here (bash --noprofile --norc) http://stackoverflow.com/a/9357501 and I get this: I tried another monitor with the same issue as well. I'm just thinking it over and realize that maybe the problem comes from the fact that one of my monitors is a USB based monitor? http://www.amazon.com/StarTech-com-USB-VGA-Adapter-USB2VGAPRO2/dp/B009L14FHI I've never head any other problems with it.... sorry for not mentioning it earlier.... but I don't think that's the issue anyway as I get the same error no matter which monitor I try... |
|
Maybe it's something to do with my ffmpeg? here's a dump of it's version info: |
|
No, it is simply that So the error must be with $ system_profiler SPDisplaysDataTypeCould you run the above command and paste the output of it. |
|
hey... i just ran that command and see that only 2 monitors are shown, though I have 3. and maybe this is what's missing? I can see USB info by dumping all system_profiler output to a file: Not sure if that's helpful. And definitely don't feel you have to chase this down for me... My use case (if the problem is the USB monitor) is probably < 5% of users, I'd think.... |
|
OK I see. The USB Display does not show any information about screen resolution, so the whole regex fails. I have added a check to remove the I pushed the changes, hope they work for you too. Could you also provide the following output with all three monitors attached: $ ffmpeg -f avfoundation -list_devices true -i '' 2>&1 |
|
And btw also when there is no privacy related output, could you paste (very long output) $ system_profiler |

changed the title
and for what it's worth I ran ffscreencast without external monitors attached on my laptop and it worked fine. |
|
and here's a dump of |
|
Thanks for the dumps. Anyway, the current build |
|
Sure... thanks for the effort... much appreciated! |
|
As it should work now with external USB monitors (with the drawback to not be able to get the screen resolution) I am closing. If there is still a problem on your side, please re-open. |
