OBS recording cuts short and freezes

[abisert]

Hi OBS Forums,
Today, I tried to record Roblox with OBS to little to no success.

I tried to record a few videos under 10 minutes with it only coming out to about 5-10 seconds max. There is also a fifty second video where there's only a single frame for most of the video.

Some of my specs include:
Processor: AMD E1-6010 APU with AMD Radeon R2 Graphics 1.35 GHz
RAM: 4.00 GB (3.43 GB usable)

17:33:04.595: Output 'adv_file_output': Number of lagged frames due to rendering lag/stalls: 15026 (74.9%)
17:33:06.337: Video stopped, number of skipped frames due to encoding lag: 2207/2251 (98.0%)

AMD APUs are notoriously weak, both on the GPU and CPU sides. Real-time video encoding is an extremely demanding task, especially when also playing a video game. Worse, the AMD AMF encoder uses game-rendering resources (also OBS GPU-time housekeeping resources) so can't be used to offload encoding, as it's already overloaded too. That system RAM is below minimum, and APUs also use it for (very slow) video memory, which OBS uses extensively.

To have a chance of success, you'll likely need to use x264 Software with the Ultrafast preset or low-CPU option (in Simple output mode), run OBS as Administrator, set your game's video options to the lowest settings possible with vsync enabled to limit the GPU usage as much as possible. You may also need to downscale even further than 720p.

Really though, your system is significantly below the performance specs needed to actually use OBS.

Alright, thank you so much for the advice.
