Issue with seek when running in Node

[richardlevy]

Hi,

I've implemented a Node based Aurora player, which plays FLAC and (some!)MP3. I added seek functionality last night by simply using player.seek() but I get this error:

TypeError: Cannot call method 'once' of undefined at Player.seek (/Users/rich/Development/AV/player.js:132:18)

The undefined object is a queue object :

132 : this.queue.once('ready', (function(_this) {

Which I assume is internal to the player as I haven't created or initialized any form of queue.

Have I missed something in the node environment?

Thanks
Rich

What kind of file are you trying to play? There is currently no seeking support in flac.js (see audiocogs/flac.js#8)

I tried with MP3 and FLAC.

Maybe this comment can help.
The point is flac.js uses seektables to perform a seek. As it's not an accurate way of seeking, it will jump to the closer seek point rather than calculating the right point to continue playing the song.

Indeed, if the file has a seektable with seek points every seconds, seeking should work well.
So if seeking fail, adding a proper seektable to a flac file with metaflac might help:
metaflac --add-seekpoint=1s *.flac

I manage to get seeking work with the above command. Once a song has a seektable, I can use seek while it plays.

I don't know if this could be of any help as you're working "in the node environment" (I've done it in the browser), but I think it's worth mentioning it.
