Streaming processing for video #212

Open Juszoe opened 2 years ago

Juszoe commented 2 years ago

I noticed that inference_realesrgan_video.py outputs the temporary frame to png file. This way takes up a lot of storage space(~500GB for 24min input and 4K output) when video have numerous frames. I optimized the code by streaming processing without temporary file. Howerver, inference_realesrgan_video.py has redundancy feature that hard to optimizing. I think inference_realesrgan_video.py need to focus on video-to-video so i delete some feature. My pull requests will be release soon.

我注意到inference_realesrgan_video.py会输出大量的临时png文件，当视频有大量帧的时候，这种方式会浪费大量的储存空间(~500GB for 24分钟输入/4K输出)。 通过流处理的方式可以在无需临时文件的情况下很好地优化代码，但是代码有些冗余功能难以优化，于是我就砍掉了这部分功能，因为我认为inference_realesrgan_video.py应该专注于video-to-video. 过段时间我会提PR

我删除了image input和imge output相关的功能 @xinntao 请问你认为这些功能还需要保留吗？
