Im working on a video editing project and im using ffmpeg for video rendering
To play video before rendering i wana show it to user and i thought of using ffplay
ffplay -i C:/Users/thota/OneDrive/Desktop/VET/test.mp4 -filter:a "volume="1.0",atempo="1.0"" -vf "transpose=2,transpose=2,setpts=1/"1.0"*PTS,scale="1280*720"" -aspect 16:9 D:/videos.mp4output.mp4
but this is giving an error:
Failed to set value 'volume=1.0,atempo=1.0' for option 'filter:a': Option not found
ffplay only recognizes -vf/-af for video and audio filters respectively.
-af "volume=1.0,atempo=1.0"
