Blank (gray) event frames in the output video

[mohsij]

Hi,

I've been using the latest version of v2e and it seems that some frames are either blank (gray) or the event pixels are all less intense than the last frame. The object in the input video is moving consistently. The last good commit for me is 1edd9e3d2b30435edf4759ffc1c3703c572c73c0 where the event frames look consistent and I get no blank frames.

My run command is: v2e -i frames --overwrite --input_frame_rate=10
--timestamp_resolution=0.1 --disable_slomo --auto_timestamp_resolution=False
--dvs_exposure duration 0.1 --output_folder=event_data --overwrite --pos_thres=.15 --neg_thres=.15
--sigma_thres=0.3 --dvs_text events.csv --output_width=1280 --output_height=720 --cutoff_hz=30 --avi_frame_rate=10
--refractory_period 0 --dvs_aedat2 None

What was changed after that commit that I could get blank frames?

Thanks
