Question / Help OBS never finish recording, file lost even with MKV

[Molda]

Hi,
i am having weird problem with OBS recently. I am recording while streaming and after i stop the stream, the recording cannot be stopped. I have read that this can sometimes happen and all you have to do is avoid using mp4 and use MKV for example and even though OBS crash or something, you wont loose the recording. Problem for me is, that it doesnt happen "sometimes" but always! And even with the MKV method, i still loose the file.
Or to be precise, the file is there but always only few seconds or minutes long even though it should be several hours.
I am recording/streaming with my PC via elgato HD capture card from PS4 and i am using HDMI switch on my monitor to switch from seeing windows to see my PS4. Could this somehow be the problem?
Because from the logs, it seems, that there is some kind of a problem that is happening roughly around the time I switch the screen. (but on the other hand it happened also when i switched the screen with HDMI switcher before i started streaming/recording.

Here is a section of two logs from last two streams where it happened:

nobody can help?

turn down you bit rate and have the stream use your gpu instead of your cpu

why? can you elaborate this bit more? bit rate is already quite low and the CPU and the GPU are powerful enough i think, the usage while streaming/recording is not high

The recording settings you're trying to use are incompatible with your video card.
We need the full log.

settings incompatible with my graphics card? I have Nvidia GTX 970 and I have been using that settings without problems for months. But here is the full log attached. thanks

OBS Studio log did show something, that happens 6 minutes after NVENC started.

This might be the graphics card or drivers failing to correctly stop NVDEC (Nvidia decoder) from media source (ffmpeg_source) causing problems with NVENC. You can try to turn off "Use Hardware decoding when available" on your "Countdown" and other video sources.

Right after switching away from 'Transition to Whatever':
16:26:50.362: error: Failed locking nvenc input buffer: invalid version (15)
16:26:50.362: [NVENC encoder: 'streaming_h264'] nvenc_encode: Error encoding: Invalid argument
16:26:50.362: error: EncodePicture failed!: invalid version (15)

it is from the Possible NVENC encoder causes crashes when I switch scenes?

 

[Molda]

i havent find the "hardware decoding" option they were talking about anywhere in the OBS.

Look at Media Sources properties.
