FFmpeg .net crash: Value cannot be null. (Parameter 'ptr')

Post by VocalFan »

Me and the leading developer are confused on why this crash is occurring. In Ryujinx, we use FFmpeg for decoding H264 videos for NVdec emulation, however, it seems that on AMD GPUs on linux, we get an exception of: Value cannot be null. (Parameter 'ptr'). I will try to provide any additional information if requested. All Nvidia GPUs seem to not have to exception, either, from GDK's continuous testing for the issue.

In the github issue you posted about this, you mentioned that it is a recent thing. Does that mean it used to work for those AMD pc's with that specific video? Does it happen with every video now or only that specific one?
If you think the issue is solved, edit your original post and add the word solved to the title.

It occurs with ALL FFmpeg videos. Megamix crashes on the "Sega" video, NASB crashes on the main menu, Deemo crashes on any videos, some SSBU final smashes crash as well due to being a cutscene video. I was able to play Megamix a few months before this, now they all crash.
