Question / Help OBS not recognizing source video

[Nico Lumermann]

Hello my friends,

So I have a flight simulator and love streaming my flights:
https://www.youtube.com/channel/UCFrr16hu6X_-mnVaIGJZ5MA

The above is not to advertise... just to show you the application.

So I connected 3 GoPros to the Magewell HDMI USB and all three work perfect.

However, I tried installing OBS in a separate PC to be able to "display screens" and get more audio sources. When I installed in the new PC.... OBS does recognize the USB cards but the video is not coming through. I then purchased and installed an Armedia capture card and a Magewell dual HDMI capture card to try my 3 GoPros that way... same problem. It only happens in this PC. The other one is fine. Here is the log file if helps:

Anyone knows what the errors in the log file could mean? in particular this:

01:37:30.847: [CoreAudio encoder]: CoreAudio AAC encoder not installed on the system or couldn't be loaded
01:37:30.847: [AMF] Encountered Exception during AMF initialization: Unable to load 'amfrt64.dll', error code 126.

Probably you are missing some important components (64bit) for your Windows. Anyway, try to run OBS Studio 32-bit (look for start menu shortcut, or application folder).

Edit: CoreAudio AAC is external encoder - not required (maybe faster a bit).
amfrt64.dll - is AMD hw encoder, you have much better encoder by NVIDIA on board.
libcef.dll...obs-browser.dll - just typical messages from full version of the obs that shipped with the Browser Source plugin (used to place html pages as sources into scenes) - it compiled from the bigger chromium project, so there is always some messages left - just ignore it.

Edit 2: Also, look for updated direct show components, codecs, drivers etc.

None of those errors are relevant, the one you should look into is this:

01:37:32.676: DShow: Run failed (0x80004002): No such interface supported

Perhaps you have some broken DirectShow filter installed.

Same issue.
Bought HD-3000 and couldn't get it to work with OBS. Also couldn't get it working via VLC either.
Took it back and swapped for Logi C920 - no difference!!

Both cameras worked with Skype and Camera app on PC.

Very frustrating. Yet to see anyone actually identify a fix, or OBS respond with anything. Are they ab;e to reproduce and then investigate?
