Audio concat #336

Closed rekha-gm closed 2 years ago

rekha-gm commented 2 years ago

I'm converting two different audio formats to mp3 using the below command. String[] nonmp3ToMp3 = new String[]{"-y","-i", path, "-acodec","libmp3lame",convertedFinalOutput};

I want to concatenate converted audios using the below command String[] mergeCmd = new String[]{"-y","-i","concat:"+convertedAudio1+"|"+convertedAudio2,"-c","copy",finalOutput};

It's concatenating, but, second audio is not getting played as there is difference in bitrates. Below is the output with error. Please let me know command to concatenate two audios with different bitrate and different formats.
