问题 I have an app, where users record audio and then "send" to each other. I'm writing "send", because actually the file is stored on server, and just provided to the recipient, when they want to listen. My issue is, that I need to reformat the recording (currently .caf) to .mp3, so they will be both smaller and so I can play them with the audioplayer I'm using. My question then is: Is it possible to have a cloud function trigger on user upload, that would take the .caf file, convert it and in

问题 I've been trying to mix an audio mp3 with a video mp4 while retaining the mp4 audio. This is working with . ffmpeg -y -i video.mp4 -i audio.mp3 -filter_complex "[0:a][1:a]amix=inputs=2:duration=longest[out]" -map 0:v -map [out] output.mp4 I'm now trying to adjust the volumes of the sound files (video 0.5, audio 1) as part of the mix. I've been trying things like ffmpeg -i 020c276b-face-4bb3-9169-e8969c1232ba.mp4 -i test.mp3 -filter_complex "[0:a]aformat=sample_fmts=fltp:sample_rates=44100

问题 I am using firebase storage to upload audio from my android app and then download and play in my app. The audio file gets uploaded but when I play it from firebase storage,it comes in a video format like image below and does not play the audio.

Uri file = Uri.fromFile(new File(fileName)); //filename is audio stored in my phone's local

问题 I'm currently using child_process and command-line mplayer to play audio on the local machine, with my Node.JS application. This works, but it's not really an excellent solution. My biggest issue is that it takes 500ms from mplayer is started to audio starts playing. Are there better ways to play audio? Preferably compressed audio, but I'll take what I can get. 回答1: I think what you asking is there any good modules that work with audio in the nodejs ecosystem? Whenever you have this type of
