Segmentation fault with AMD GPU on start #79
Description
Describe the Bug
This was previously mentioned on loki's repo here, but since it hasn't been addressed, and this is the currently maintained repo, I figured I'd mention it here as well.
The debug logs output no errors, however the program segfaults and exits without any additional context. It seems to only occur on AMD GPUs since all other reported instances of this error happened on AMD GPUs, however I could be mistaken.
In the previous issue, it was narrowed down to the free_ctx method in sunshine/video.cpp.
void free_ctx(AVCodecContext *ctx) {
//avcodec_free_context(&ctx);
}
Commenting out this line allows Sunshine to run, although I'm sure that's not the proper solution.
Expected Behavior
The program is expected to open and start normally, but instead a segmentation fault occurs.
