I have an issue using ffmpeg with V-Ray exr.

I'm trying to export .mp4 from .exr, so ihave used this command

ffmpeg.exe -y -start_number 1 -framerate 25 -i D:\temp\WAC_TEST\what_about_cooking_sq01_p040_rendering_main_publish_v000.%4d.exr -pix_fmt gbrapf32le D:/out_vray_exr.mp4

I have verified parameters using

ffmpeg.exe -y -start_number 1 -i D:\temp\WAC_TEST\what_about_cooking_sq01_p040_rendering_main_publish_v000.%4d.exr

Result :

Input #0, image2, from Input #0, image2, from 'D:\temp\WAC_TEST\what_about_cooking_sq01_p040_rendering_main_publish_v000.%4d.exr': Duration: 00:00:02.00, start: 0.000000, bitrate: N/A Stream #0:0: Video: exr, gbrapf32le, 2840x1210 [SAR 1:1 DAR 284:121], 25 fps, 25 tbr, 25 tbn

Finally, Exported video are unreadable by windows player and KMplayer

I can play the video using VLC. but i got stuttering frame like this: https://www.youtube.com/watch?v=C8MawpkKGfc

To understand this behaviour i have export .exr sequence to .png and i got this

I also tried this command with a simple cube animation using mantra on Houdini, it's just work perfectly, but if i export this cube animation using vray, i got stuterring frame and this strange behaviour.

Thank you.
