Sound replacing stopped working

ffmpeg.exe -i new_audio.mp3 -i audio_and_video.mp4 -c copy out.mp4

not works with:
ffmpeg-20190730-b3b7523-win64-shared.zip
ffmpeg-20190821-661a9b2-win64-shared.zip

works with ffmpeg-20190608-b6ca032-win64-shared.zip and earlier.

[Carl Eugen Hoyos]

Please provide the failing command line together with the complete, uncut console output to make this a valid ticket.

Change since 11d3b03fcb2baae4324aac9481b9bd4a171d4345

The MP3 demuxer does not set any stream disposition, so the MP4's audio stream is scored higher.

Workaround is to map explicitly:

ffmpeg.exe -i new_audio.mp3 -i audio_and_video.mp4 -map 1 -map -1:a -map 0:a -c copy out.mp4
