CasparCg new installation unexpected behaviour

kush1991 · June 17, 2018, 11:01am

I upgraded my caspar installation a couple of days back; built the Server from the “server-master” VS2017 and got the client from the pre built repository, i.e. Nov 2017 build. When I am using a FFmpeg producer for the “AMB.mp4” I see a complete blue screen on the screen consumer. Similarly when i play the default template “caspar_text.ft” I see a diagonally cut output on the screen consumer

. There are also some errors thrown in the console window, most of which are due to the media-scanner not running.
Console Log:

Initialized ffmpeg module.
Initialized oal module.
Initialized decklink module.
Initialized screen module.
Initialized html module.
Initialized flash module.
Initialized newtek module.
Initialized bluefish module.
Initialized image module.

Can you check what exact revision you built please. It should be at the beginning of the log or the window name for the console window.

There have been some recent changes that sound very similar to this, but that should all be resolved now.

If you could try some versions from builds.casparcg.com to find out when this issue started that would also be really helpful.

kush1991 · June 17, 2018, 12:17pm

Thank you for the quick reply Julusian.
The server snapshot was from “11-Jun-2018”, and I tried with the “16-Jun-2018 20:55” build from the link you provided and the problem still is the same;

in the above screen capture the blue background is the AMB.mp4 playing in the background and the caspar_text.ft in foreground with no mixers applied.

I am a cpp developer, could you point me to the similar issue to your knowledge, I would be more then happy to help.

Julusian · June 17, 2018, 1:52pm

Hmm, that’s interesting… If you could try the one from 30th that will help determine if it could have been caused by the changes I am thinking.

Could you also make sure you are using latest graphics drivers, to try and rule that out as a cause.

The changes in question are:

In particular the solid blue could be something wrong with the result of the perspective calculations, and the half could be similar. (these are both things I had occur while doing the original pr)
I’m not aware of anyone else trying this on an amd card, so they could be more picky.

kush1991 · June 17, 2018, 2:04pm

I have not digged into the code yet, but from the builds i figured out, the problem does not exist in the 2nd-May build but starts from 4-May and worsens ahead.
I will check with the drivers, and also see the probable commits between the dates and get back.

Thank you Julusian

(just a quick note aside, as always with these kinds of GPU related issues: please make sure you’re on the latest drivers. I know, it might be superfluous to state, but people sometimes forget after all)

kush1991 · June 18, 2018, 3:43pm

@mint thanks for the pointer, and its not superfluous to state, I know drivers can be a real pain at times; by the way the drivers are updated.
And I checked the fix for #989 #999 issue as you stated @Julusian and reverted it, the problem seems to be fixed to a level, the blue screen instead of the video, renders the video now but clipped diagonally,
