ffmpeg で動画を結合する方法 2 mpd ファイル編(memo)
ffmpeg で動画を結合する方法
基本的な手順は上記の URL を参照しつつ実施しました。
上記の手順で詰まったところを補足しています。
環境
ffmpeg は今回 WSL 入れて、Ubuntu 上で下記を実施してインストールしました。
sudo apt install ffmpeg
手順
- mp4 ファイルを作成。作成方法は問わず。
- 下記コマンドを実行する
ffmpeg -re -i test.mp4 -map 0 -map 0 -c:v:0 copy -c:a:0 copy \ -filter:v:1 "scale=-2:360" -c:v:1 libx264 -profile:v:1 main -b:v:1 600k -c:a:1 aac -b:a:1 128k \ -f dash -window_size 5 -adaptation_sets "id=0,streams=v id=1,streams=a" \ -movflags +faststart test.mpd
