(The input is anycodings_ffmpeg 720x480 with a 32:27 sample aspect ratio. but squishes it vertically and anycodings_ffmpeg adds pillarboxing anyway. I've tried -vf anycodings_ffmpeg scale=768:432:force_original_aspect_ratio=decrease,pad=768:432:(ow-iw)/2:(oh-ih)/2, anycodings_ffmpeg which produces a 768x432 16:9 video from a anycodings_ffmpeg 16:9 input. I anycodings_ffmpeg want them to scale up or down to fit within anycodings_ffmpeg the desired output size (768x432), anycodings_ffmpeg preserving their aspect ratio by anycodings_ffmpeg pillarboxing when necessary. I want to anycodings_ffmpeg concatenate them into one long video, like a anycodings_ffmpeg playlist, which means re-encoding them. I have a number of videos of varying sample anycodings_ffmpeg and display aspect ratios(and different anycodings_ffmpeg framerates and timebases). For example, try the following command line: ffmpeg -i input.avi -vf scale1280:720 output.avi, to cut out unwanted.

The setsar filter sets the Sample (aka Pixel) Aspect Ratio for the filter output video. Does FFmpeg use GPU?įFmpeg uses Video Codec SDK If you have an NVIDIA GPU which supports hardware-accelerated video encoding and decoding, it's simply a matter of compiling FFmpeg binary with the required support for NVIDIA libraries and using the resulting binaries to speed up video encoding/decoding.
