Expected Behavior

I used the official version before the beta version, and the replay buffer was saved normally at that time

Current Behavior

The screen is dark! ! I can't see the game screen! ! yes! ? ! ?
Beta1 and Beta2 had the same phenomenon, rc1 had the same phenomenon, sad if it's a bug that hasn't been discovered yet.

Steps to Reproduce

1.start replay buffer
2.Save videos up to the number of seconds set in the replay buffer
3.Something... the screen is dark and only the audio is playing...
...

Anything else we should know?

First (already the last column) I'm a Japanese OBS fan, and I'm writing using Google Interpreter. thank you!

First, the number of seconds I set for the replay buffer is 480s.
And if you save the replay at 480s or less, the video file will be saved normally with both video and audio.

I don't know if it's necessary, but the video file when saving a replay is not a thumbnail notation of the video, but a video icon when loading... (sorry if it's hard to understand)
It usually shows a thumbnail of the video

Pretend to be loading no matter how many minutes or hours you wait (see image

)

Confirmed this with about 8 minutes of replay buffer running, ffprobe tells me the video stream's headers are broken:

[mov,mp4,m4a,3gp,3g2,mj2 @ 0x140604f50] stream 0, missing mandatory atoms, broken header
[mov,mp4,m4a,3gp,3g2,mj2 @ 0x140604f50] Could not find codec parameters for stream 0 (Video: h264 (avc1 / 0x31637661), none(bt709), 1280x720): unspecified pixel format
Consider increasing the value for the 'analyzeduration' (0) and 'probesize' (5000000) options
