Question / Help Failed to start recording with AMD encoder

So I recently installed the latest version of OBS Studio (20.0.1) and the AMD encoder plugin from https://obsproject.com/forum/resour...-framework-encoder-plugin-for-obs-studio.427/. However, every time I try to record using the H264/AVC Encoder (AMD Advanced Media Framework) encoder, it tells me "Failed to start recording
Starting the output failed. Please check the log for details.

NOTE: If you are using the NVENC or AMD encoders, make sure your video drivers are up to date."

I have updated my AMD drivers to the latest (17.8.1) and reinstalling OBS Studio and the plugin (a lot), but none of that worked. Sometimes when I reinstall the plugin, it lets me record once. However, when I stop the recording and start again, it gives me the error message.

Earlier this year I was using an OBS Studio version from January(?) and the encoder settings had AMD Video Coding Engine H.264 Encoder (Media Foundation) on the list. Nothing happened when I used it, so in July, I installed an earlier version of the plugin, and using AMD Video Coding Engine H.264 Encoder (Media Foundation) worked. More recently, something came up that led to me reinstalling OBS Studio and the plugin, but having done that, the encoder settings now listed both H264/AVC Encoder (AMD Advanced Media Framework) AND AMD Video Coding Engine H.264 Encoder (Media Foundation). After I chose H264/AVC Encoder (AMD Advanced Media Framework), applied, and exited the settings, AMD Video Coding Engine H.264 Encoder (Media Foundation) no longer showed up on the list. Unfortunately I do not have the log files for the previous versions of OBS Studio and the plugin.

I don't understand how this could have worked a month ago and then break after updating. I have used the same laptop.
 
I am having the same issue, and have gone through the steps of ensuring up-to-date drivers and uninstall/reinstall, but I am still getting the "Failed to start recording. Starting the output failed. Please check the log for details. NOTE: If you are using the NVENC or AMD encoders, make sure your video drivers are up to date." error message.
 
Update your GPU drivers if you haven't already, or better yet perform a clean install for them.

I updated to the recommended (17.7.1 or 17.1.2) and it wouldn't work, so i updated to the optional drivers 17.8.1. still doesn't work

As a clean install? That's impressive if you managed to do that in less than 2 minutes. Your issue is that the encoder is available, but can't be initialized:
Code: 
21:50:11.962: [AMF] <Id: 9> Failed to initialize encoder, error AMF_ENCODER_NOT_PRESENT (code 36)

I would need a more verbose log from OBS, enable the "Debug" option in the encoder settings and then start OBS with --verbose --unfiltered_log appended to the shortcut. Be aware that the produced log will likely be several megabytes big, so you will have to compress in using WinRar, 7-zip or similar before uploading.

As a clean install? That's impressive if you managed to do that in less than 2 minutes. Your issue is that the encoder is available, but can't be initialized:

no i had already updated drivers from before. they weren't clean installs though, they were just updates from older driver versions. i updated them because of this problem, and that didn't work, so i made this post

i enabled the debug thing in both the streaming and recording settings and added "--verbose --unfiltered_log" to the end of Target in the shortcut options. the file isn't actually big though, 42kb. did i miss something?

That log is weird. It manages to successfully create a H264 encoder on both DirectX 11 and DirectX 9, but when it comes to actual encoding it fails. This is very likely a driver bug, by what it's caused is hard to say.

ok so i used AMD's clean uninstall thing, then reinstalled the drivers. it installed driver version 17.7.2, but when i tried obs, the AMD encoding option wasn't there, and it wouldn't appear after reinstalling obs studio and the plugin. so i updated from 17.7.2 to 17.8.1. the amd encoding option is there again.

i was able to record ONCE after reinstalling and updating the drivers to 17.8.1, as my log file will hopefully show (i don't know how to read them lol) but then it wouldn't start recording again after i stopped it

Code: 
22:30:03.634: [AMF Runtime] [22:30:03.634][AMFEncoderVCE]    Error: ..\..\..\..\..\runtime\src\components\EncoderVCE\EncoderVCEImpl.cpp(843):AMF_ERROR 1 : AMF_FAIL: Init() - Could not change encoder state

Looks like an actual driver bug, report it through the driver report form. I will open an issue on the AMF issue tracker for this too.

how/where do i do that?
 
So, i had the same problem on my hp laptop, i installed the latest version of the graphics driver, and when the laptop restarted, obs wouldn't open, it would just crash. So, i right-clicked on the shortcut on the desktop, and ran the compatibility checker, it ran its course, and optimized the settings for obs, and obs runs perfectly now.
