about concat, thanks a lot #176

Open lwx2004 opened 2 years ago

Today I used jave2 to try to process audio files, such as merging two mp3 files. The version I used is 3.2.0. Oh my god, it actually provides a closed method to merge multiple files. I tried it and it didn’t work. The output file only contains one file data in the source file I specified. I took a look at the generated ffmpeg command, which did not contain concat but multiple -i parameters. But I took a look at earlier versions, such as 2.7.3, which included the concat statement when creating the ffmpeg command. Is this a bug? thanks

Could you please provide some more infos on this? For example the command lines generated in both versions?

I think we need to have two different concat versions. One for concating identical media files, as you use above (And was default in pre 3.2.0) And a second one including scaling/reencoding to concat different media formats

Sorry, I’m busy with other things recently, I’m going to test the parameters generated by the two versions now

lwx2004 commented 2 years ago

Could you please provide some more infos on this? For example the command lines generated in both versions?

version 2.7.3 ffmpeg -i concat:D:\test\test2.mp3|D:\test\test1.mp3 -vn -acodec copy -ab 320000 -ac 2 -ar 44100 -y D:\test\combine.mp3

version 3.2.0 ffmpeg -i D:\test\test2.mp3 -i D:\test\test1.mp3 -vn -acodec copy -ab 320000 -ac 2 -ar 44100 -y D:\test\combine.mp3
