Invalid path issue when trying to save decoded frames

I have a some YUV videos I want to run tests on but the test_video script fails with the following error:

FileNotFoundError: [Errno 2] No such file or directory: 'out_bin\\clic_mini\2b2883e1147e879ed7c423e0beccf3edde46d98462c26c965f1286086aba7df5_1922x1080_30fps_yuv420p_299frames_56kbps.yuv_q0.mp4/out.yuv'

What I think is happening:

• Line 466 in test_video.py: args['curr_rec_path'] = args['curr_bin_path'].replace('.bin', '.mp4')
• Line 291 in test_video.py: output_yuv_path = args['curr_rec_path'].replace('.yuv', f'_{total_kbps}kbps.yuv')

This two lines cause the output path to look like: out_bin\\clic_mini\2b2883e1147e879ed7c423e0beccf3edde46d98462c26c965f1286086aba7df5_1922x1080_30fps_yuv420p_299frames_56kbps.yuv_q0.mp4

However, inside YUV420Writer:

class YUV420Writer():
    def __init__(self, dst_path, width, height):
        if not dst_path.endswith('.yuv'):
            dst_path = dst_path + '/out.yuv'
        self.dst_path = dst_path
        self.width = width
        self.height = height

        self.file = open(dst_path, 'wb')

Since output_yuv_path end with .mp4, dst_path will end up as: out_bin\clic_mini\2b2883e1147e879ed7c423e0beccf3edde46d98462c26c965f1286086aba7df5_1922x1080_30fps_yuv420p_299frames_56kbps.yuv_q0.mp4/out.yuv'.

This create a path that goes through a directory that does not exist - 2b2883e1147e879ed7c423e0beccf3edde46d98462c26c965f1286086aba7df5_1922x1080_30fps_yuv420p_299frames_56kbps.yuv_q0.mp4, and as a result the line self.file = open(dst_path, 'wb') fails.

I currently don't see any mistake in the way I invoked the script, so any help would be appreciated.

Start in test_video.py at lines 291 and 466, then inspect YUV420Writer's destination-path handling. Reproduce the failure with a YUV420 test video and verify that the output path is treated consistently, so saving decoded frames no longer appends out.yuv beneath an .mp4 path.
