Research direction
Start at the run_one_point_fast path and inspect the save_decoded_frame block using PNGWriter and ycbcr444_to_rgb. Compare the saved frame with the decoded tensor and the reported metrics, then verify that the saved image has matching colors and no PSNR drop.

Description
I try to save the decoded frame of DCVC-FM of run_one_point_fast, so I add the code below:
recon_writer = PNGWriter(args['bin_folder'], args['src_width'], args['src_height'])
and
if save_decoded_frame:
yuv_rec = x_hat.squeeze(0).cpu().numpy()
rgb = ycbcr444_to_rgb(yuv_rec[:1, :, :], yuv_rec[1:, :, :])
recon_writer.write_one_frame(rgb=rgb, src_format='rgb')
The metrics of saved json is as the paper report, but the result have obvious color differences and a 8dB PSNR drop.
