Question / Help Video from capture card behind audio

[Mist_Shark]

I am using a capture card (AVerMedia Live Gamer HD) to stream game play to twitch from various consoles. I have streamed 2 different games from the Nintendo Switch and one Wii game on WiiU with no issues but when I try to stream a game from my PS4 the video from the game ends up behind the audio. When I watch my stream I hear what I've done in game first before it happens visually.

During the stream covered by the log file I encountered an issue where the game audio was way out of sync that I fixed by getting the capture card source to refresh. The issues where the game video comes way after the audio usually happens and becomes more noticeable after the stream has been live for more than 2 hours. The game video being behind the game audio from the capture card was happening on a different PC with a different capture card as well.

Just noticed I linked the wrong log. The one from my original post was from yesterday and I didn't notice any issues (was streaming a Nintendo Switch game).

This is the one I meant to post above (game is on PS4).

Does anybody know how to fix this?

Hmm, from your log:

11:31:37.546: warning: Could not update timestamps for skipped samples.
11:31:37.559: adding 21 milliseconds of audio buffering, total audio buffering is now 42 milliseconds
11:31:38.141: adding 21 milliseconds of audio buffering, total audio buffering is now 64 milliseconds
11:31:44.521: warning: Could not update timestamps for discarded samples.
11:31:44.547: warning: Could not update timestamps for skipped samples.

Plus a ton more audio buffering increase messages. First guess would be that you're overloading your system PCIe bus somehow, causing the audio to lose sync. The PS4 captures at a higher resolution than the Switch/WiiU, so this could account for why it works there but not with the PS4.

I have my PS4 set to 720. Running the same PS4 games and streaming them with another stream software (at the same resolution) and not having any issues at all with the game audio and video falling out of sync.

(Edit) thx for the reply btw

Forgot to say there was one game I played on the WiiU virtual console (Metroid Fusion) that when streamed had the same issue where the video fell behind the audio.

Are you able to run a test using AverMedia's software to see if the audio is desyncing?

Timestamp issues like this should be fixed in the latest version of OBS, and I'm wondering if something in the capture card itself is failing/faulty.

This was happening with an Elgato HD external capture card as well. And ì am running the same games with a different streaming software and the Avermedia card and not having any issues at all with audio/video desync
