20230403 Call NVIDIA's hardware-accelerated wmv video transcoding to MP4 format through ffmpeg under WIN10
2023/4/3 15:50
I recently learned Japanese, and most of the videos I found in Japanese pronunciation are in MP4 format, and a few are in WMV format. PR2023 does not seem to recognize WMV format.
So: the almighty ffmpeg is here!
Manually specify the codec
Check the codec of vc1 through ffmpeg -codecs | findstr "vc1"
You can see that there are vc1_qsv dedicated to i card and vc1_cuivid decoder dedicated to N card
Add the parameter -c:v to specify the decoder: ffmpeg -c:v vc1_cuvid -i input2.wmv -c:v h264_nvenc output.mp4 (choose the corresponding codec according to your graphics card, I am an N card here, so I chose vc1_cuvid as decoder, h264_nvenc as encoder)
It can be seen that the transcoding speed is very fast, and the hardware codec is also fully utilized, and the CPU usage is also low.
Also note that the default encoding output of nvenc is 2000k bit rate, you can manually set the bit rate to reduce the loss of image quality.
ffmpeg -c:v vc1_cuvid -i input2.wmv -c:v h264_nvenc output.mp4

During the transcoding process, the consumption of CPU and GPU is relatively large, maybe the computer I use is relatively old/classic!
