Error ffmpeg when using only CPU

[MoonDragon-MD]

Hi I tried the new version v2.2.0, with Docker and with CPU only, the result is that it can't create videos with ffmpeg because it uses NVIDIA codecs, you should add a check if it is CPU use “normal” codecs, thanks for your great work!!!

Though you put “check_gpu_available” is not sufficent, maybe a docker problem.

However I solved it by replacing “h264_nvenc” with “libx264”. (step7 & step12)

One idea would be to do a check if the /*/*NVIDIA*.so file exists, which in fact is what it would go to.

1. open "step7_merge_sub_to_vid.py" , Line 84 changed: ### gpu_available = check_gpu_available() gpu_available = False # 强制用CPU,因为没有安装NVIDIA GPU驱动，如果有NVIDIA GPU驱动可以打开上面的注释

2. open "step7_merge_sub_to_vid.py" , Line 73 changed: ### gpu_available = check_gpu_available() gpu_available = False # 强制用CPU,因为没有安装GUP驱动，如果有驱动可以打开上面的注释 if gpu_available: rprint("[bold green]Using GPU acceleration...[/bold green]") cmd.extend(['-map', '[v]', '-map', '[a]', '-c:v', 'h264_nvenc']) else: cmd.extend(['-map', '[v]', '-map', '[a]'])

@alittlegoldfish The problem with using this method is that if I have cuda support for other operations I cannot then use it, instead you should add a check for the file “libnvidia-encode.so.1” and if it does not exist use “libx264” (Or at least add it as a fallback) instead of “h264_nvenc” @Huanshere
