Want to store video frames to memory

[Rajdeepc]

Hi, Is they any way I can modify the output param to store the frames in memory instead of writing them to files? My use case is to extract the frames from video and transfer them to canvas ctx to porduce an apng.

also want to know, every time i use filter and output file to disk, then add watermark and create a new ffmpegcommand from disk， this is very cumbersome

this is a example, https://github.com/fluent-ffmpeg/node-fluent-ffmpeg/issues/1144#issuecomment-1895508239

if you want to export to other image formats, you need to find Hex signature (https://en.wikipedia.org/wiki/List_of_file_signatures) and re-divide the memory chunks
