audiocogs / jsmad Goto Github PK

when a file's end is reached, jsmad throws

Uncaught Header decoding failed
Mad.Frame.decodeframe.js:366
refillplayer.js:62
(anonymous function)player.js:92
AUDIOLIB.SinkClass.processaudiolib.js:2550
bufferFill

then it starts throwing

Uncaught TypeError: Cannot read property 'flags' of null
Mad.Frame.decodeframe.js:362
refillplayer.js:62
(anonymous function)player.js:92
AUDIOLIB.SinkClass.processaudiolib.js:2550

This is because it's trying to do subarray on something that isn't a typed array. I have a fix ready.

the readme indicates that only MPEG-1 Layer III is supported, but when I tried an mp2 ( MPEG-1 Layer II - http://en.wikipedia.org/wiki/MPEG-1_Audio_Layer_II) in the demo, it worked just fine. Is this an accident, or did someone make a fix to enable Layer II?

Refering to https://github.com/ofmlabs/jsmad/blob/master/src/frame.js#L111

Specs says that the 16-bit crc comes after the frame header. Therefore the skip should be located at https://github.com/ofmlabs/jsmad/blob/master/src/frame.js#L172.

Mad.Player needs some hooks so that people can add visualizations or whatever postprocessing to the audio.

That's the mp3 that fails.

The way I have hacked track switch is a kill() followed by another playUrl(). This is obviously isn't optimal and there has to be some kind of way to switch the streams and have it play gracefully from the new stream. The way it works now 1 or 2 seconds of the previous track play when it switches to the next.

Any ideas/help hints would be much appreciated. This works stellar even in the face of that one issue 👍

hi, i had a quick look at the sources and it looks to me as if you are expecting what ever file is played, to be loaded completely.

how can i use jsmad to play a live stream?

i want to use it to play live captured system audio for my h264 remote console
