I want to play a audio book file xxx.m4b in a web app, but I can't find a package to handle the m4b file. I find a possible package called ffmpeg but I have no idea how to implement it. How can I play a audio book file in a web app or just natively in my desktop?

The actual task is to play mp3 file that should be embedded with the electron app.
I placed the mp3 file near my electron app "main.js".
I wanted to play it using some "sound-play" (https://github.com/nomadhoc/sound-play) package using bridge api, but it didn't worked out, sound is not playing.
So I want to just play it using an audio element (which seems to be more universal), but I don't get what src url I should supply to it. And then I wonder how to correctly add an additional asset to the built version (I'm using electron-builder).
Working with extra/local resources in election apps is kind of obscure topic for me. Advice would be appreciated.
My scenario is to pull data from a RTSP source via ffmpeg, send it to nginx-rtmp, and use nginx to provide hls playback. There are quite a lot of tutorials and q&a's on the internet. I followed this one:
https://docs.peer5.com/guides/setting-up-hls-live-streaming-server-using-nginx/
However, it miserably failed. To make things simpler to understand, I would like to ask the core question:
Who is responsible to create the m3u8 playlist file?
I tried to experiment in two steps: first, try to push a local mp4 file and play it back via HLS:
Following the above tutorial, I try to use ffmpeg to push a local mp4 file to nginx-rtmp, and use videojs to play it. The browser reported error:
VIDEOJS: ERROR: (CODE:4 MEDIA_ERR_SRC_NOT_SUPPORTED) No compatible source was found for this media.
Secondly, I have successfully saved the video file pushed to nginx-rtmp as a series of FLV file, and I know that I can use exec_push to call ffmpeg to convert flv to a format that is compatible with HLS. Again, here the core question is, howto create and UPDATE the m3u8 file as new video data is coming in endlessly.
For now, I would like experts to help me tackle the first question -- playback static mp4 file through HLS. Any tutorials on m3u8 playlist and mpeg-ts files are also much appreciated!
The nginx-rtmp module by itself creates and updates the playlist as new segments arrive.
To troubleshoot check if the .m3u8 files are created under the folder specified in hls_path of your nginx conf. Rest is just nginx serving a file using http.
If that works try the HLS url directly in safari (safari got inbuilt HLS player) or in Chrome (Play HLS M3u8) extension enabled.
If that works the problem must be with your player.html
In the Additional Steps section at the foot of MAS: Packaging your app, I read:
To ensure proper validation [of your NWJS app for the Mac App Store], you have to check those steps:
Delete the FFMPEG library:
rm "YourApp.app/Contents/Frameworks/nwjs
Framework.framework/Libraries/ffmpegsumo.so"
Note: Currently, FFMPEG library cannot be submitted to Mac App Store as is.
When I delete the FFMPEG library, if my app includes (ogg) audio files and attempts to play them, the app crashes. I assume that this is because the FFMPEG library is essential for audio playback.
Does this mean that the current Mac-App-Store-friendly NWJS build (nwjs-macappstore-v0.12.3-osx-x64) does not support audio? Or is the an alternative audio library that I can use with it?
I am developing a phonegap application for iOS and Android. In iOS, recorded sound format is .wav and in android, it's .amr/.mp3. After recording, audio file gets uploaded to a web server.
I need to convert these files from .amr/.wav to .mp3 after upload - what options do I have?
I've read about ffmpeg and ffmpeg-php. Will that work with shared hosting? If yes, can someone provide any link to install it?
Any converter, which will work with shared hosting of justHost cPanel?
any php class which can send my audio file to ffmpeg server and get back mp3 file? Just thinking.
Any other option?
I don't mind the method - I need the the required output.
I've seen a tutorial about how to play local files using a background agent in WP7 Mango but it specifically states that the tutorial is related to local files:
http://msdn.microsoft.com/en-us/library/hh202978(v=VS.92).aspx
Does a similar tutorial exist for streaming files from the web?
I've used the same tutorial, and it works fine if you want to play something like a podcast that is stored as an mp3 file on a webserver. You just set an absolute Uri in the audiotrack.
I don't think you need to use the specific Streaming project unless you are doing live streaming.
