I’m a beginner with FFmpeg. I’m trying to convert MOV files to MP4 using an Intel GPU (QSV), but it’s not working. I used the following Python script:

def convert_video_mov(input_file, output_file):
    command = [
        'ffmpeg',
        '-i', input_file, 
        '-vf', 'scale=1920:1080', 
        '-c:v', 'libx264',  
        '-b:v', '2500k',  
        '-r', '30',  
        '-y',
        output_file 
    ]

    
    subprocess.run(command)


input_video_path = ['IMG_4413.MOV', 'IMG_4437.MOV']

for i in range(len(input_video_path)):
    convert_video_mov(input_video_path[i], "[conv]"+input_video_path[i])

When I run this script, I encounter the following errors:

[h264_qsv @ 0000012e3d198d40] Current pixel format is unsupported
[h264_qsv @ 0000012e3d198d40] some encoding parameters are not supported by the QSV runtime. Please double check the input parameters.

[out#0/mov @ 0000012e3d12acc0] Nothing was written into output file, because at least one of its streams received no packets.

I tried running ffmpeg -formats and saw the following two lines related to MOV:

  E  mov             QuickTime / MOV
 D   mov,mp4,m4a,3gp,3g2,mj2 QuickTime / MOV

Is there a way to solve this problem? Thank you for any replies!

I tried Intel GPU to convert MP4 to MP4 (changing the size, bit-rate), it works.
