Have you tested this with video/audio files, is time seeking working?

@dr-dimitru
tested it with static files (images, docs)
need to test it with audio/video files for time seeking.

I will let you know once i will test it.

@salmanhasni waiting for test results

So you need test results for:

• Standart request for static and streaming files (seeking may or may not work)
• Download (with ?download=true query) for static and streaming files (browser should show remaining time and speed)
• Streaming (with ?play=true query) for static and streaming files (time seeking must work)

@salmanhasni any news on your end?

@dr-dimitru sorry for the delay response, i was out for vacations.
I have tested static (images etc) and dynamic files ( video, audio),
standard and download request works fine, where as time seeking having issue in streaming files ( with ?play=truequery).

@dr-dimitru I am able to make this PR work, but for that I need to write the below redundant code (logic already exist in serve() method but only for readableStream == null) for making stream videos work with time seeking.
Should i refactor it ?

    if http.request.headers.range
      partiral = true
      array    = http.request.headers.range.split /bytes=([0-9]*)-([0-9]*)/
      start    = parseInt array[1]
      end      = parseInt array[2]
      end      = vRef.size - 1 if isNaN(end)
      take     = end - start
    else
      start    = 0
      end      = vRef.size - 1
      take     = vRef.size

    if partiral or (http.params.query.play and http.params.query.play == 'true')
      reqRange = {start, end}
      if isNaN(start) and not isNaN end
        reqRange.start = end - take
        reqRange.end   = end
      if not isNaN(start) and isNaN end
        reqRange.start = start
        reqRange.end   = start + take

      reqRange.end = vRef.size - 1 if ((start + take) >= vRef.size)

      if self.strict and (reqRange.start >= (vRef.size - 1) or reqRange.end > (vRef.size - 1))
        responseType = '416'
      else
        responseType = '206'
    else
      responseType = '200'

    var remoteReadStream;

    if responseType == "206"
      remoteReadStream = bucket.file(path).createReadStream({start: reqRange.start, end: reqRange.end});
    else if responseType == "200"
      remoteReadStream = bucket.file(path).createReadStream();

    self.serve(http, fileRef, fileRef.versions[version], version, remoteReadStream);

Just pass remoteReadStream as 5th argument to serve() method.
No need write more code, see this example: https://github.com/VeliovGroup/Meteor-Files/blob/master/demo/lib/files.collection.coffee#L86

@salmanhasni looks like I'm wrong...
Is there a way to .createReadStream form bucket with start and end?

@dr-dimitru Yes we can.

Sorry for my side, I just forgot to pass reqRange parameter in createReadStream() method call for responseType "206", please see the above update code.

@salmanhasni
Sounds like you made it work, right?
If so, does tests passed?
If tests is passed re-open this PR, and I'll merge it. :)
