現在、FFMPEGに2つのビデオを並べて配置しています。コマンドは次のとおりです。
ffmpeg -i input.mov -vf "[in] scale=1280:720, pad=2*1280:720 [left]; movie=right.mov, scale=1280:720 [right]; [left][right] overlay=1280:0 [out]" -b:v 1000k -vcodec libx264 -an sidebyside.mp4
私は今、オーディオを管理する必要があります。私は指定しようとし続けます:
-acodec libfaac -ac 2 -map 0:1 -map 0:2
最初の入力から 2 つのオーディオ チャンネルを取得して使用します。エラーが発生し続けます:
[aformat @ 0x7febf2e01fc0] auto-inserting filter 'auto-inserted resampler 0' between the filter 'src' and the filter 'aformat'
[aresample @ 0x7febf2e02180] [SWR @ 0x7febf40dd000] Input channel layout isnt supported
Error opening filters!
どのビデオがオーディオを提供するかを指定する最良の方法を探しています! アドバイスをありがとう!
完全な出力は次のとおりです。
