Screen recorded file is very large using "super+r" key.

[vivek338]

Hi,

I am working on screen recording project on imx8m-mini with weston desktop. Screen is done using "super+r" key from keyboard. Conversion is done using below command:-

wcap-decode capture.wcap --yuv4mpeg2 > capture.y4m

 capture.y4m is very large file and also have large conversion time.

How to reduce the converted size and reduce conversion time.

Please help!

Hello @vivek338 

There are many ways that I believe can help to you to improve. At first, lowering the frame rate can significantly reduce the file size.

Also you can use H.264 directly during capture instead of raw YUV. The wcap-decode tool outputs raw YUV4MPEG2 format, which is very large. Instead, use a tool that allows for more efficient encoding as ffmpeg.

I hope this information can helps to you.

Best regards,

Salas.

Hello @vivek338 

I am not an expert of this topic, but one can try to look the GStreamer documentation, it appears you can do it with GStreamer.

Maybe this link can be useful for you:

I hope this information can help to you.
