done thnx you but other problem: iphone is not supporting to filter effect on phone when im joining(merging) video...
ffmpeg -i video.mp4 -filter:v "fade=in:color=white:st=5:d=1, fade=out:color=white:st=44:d=1,format=yuv420p" filtered.mp4 ffmpeg -i intro.mp4 -c copy -bsf:v h264_mp4toannexb -f mpegts temp1.ts ffmpeg -i filtered .mp4 -c copy -bsf:v h264_mp4toannexb -f mpegts temp2.ts ffmpeg -i "concat:temp1.ts|temp2.ts" -c copy -bsf:a aac_adtstoasc output.mp4 when i am sending output.mp4 video via whatsapp. then android users can see all part of video but iphone user cant see filtered affected part. iphone user is hearing only audio of filtered video. now whats problem? thank you. pdr0 <p...@shaw.ca>, 21 Nis 2020 Sal, 18:24 tarihinde şunu yazdı: > Cemal Direk wrote > > Hi, im using this code > > > > "ffmpeg -i video.mp4 -filter:v "fade=t=in:color=white:st=0.5:d=1" > > -filter:a > > "afade=in:st=0:d=1, afade=out:st=44:d=1" -c:v libx264 -c:a aac > output.mp4" > > > > then output is wrong codec. i can not open output.mp4 at any player. > > but i dont give to color=white parameter to command i can open > > output.mp4... > > whats the problem when i adding color parameter to command?(:color=white) > > > > how can i solve this problem? > > I'm assuming you are using "regular" yuv420p input. > > The default color for fade is black.
