Question

Need help please with an error and also a glitch in my .swf :)

Ok so I will explain the two problems I am having with my Media Player at the moment and I hope I can explain it clear enough for anyone to understand

Problem #1:


I was getting an error which was error #1009 null object reference etc etc etc...

I fixed that by adding the following lines:

my_sound = new Sound();

my_channel = new SoundChannel();

Now I am getting another error which seems to be because I am streaming mp3's from a external .xml file which I am loading into my media player with the URLLoader.

The error I am getting now is:

ArgumentError: Error #2068: Invalid sound.

          at flash.media::Sound/play()

          at BasicPlayer_fla::MainTimeline/dropIt2()[BasicPlayer_fla.MainTimeline::frame1:378]

Which I may be wrong saying this but I believe I am getting this error as the audio is being streamed and the variable for what I previously had in my code:

var my_sound:Sound;

var my_channel:SoundChannel;

I had these variables already stated to hold my sound and soundchannel objects.


The error is at line 378:

// function dropIT2

// dropping slider

function dropIt2(e:Event):void

{

          if (song_paused == false)

          {

                    if (isDragging == true)

                    {

                              stopDrag();

                              var fullTime:int = Math.floor(my_sound.length/1000);

                              //my_sound.length:int = Math.ceil(my_sound.length /(my_sound.bytesLoaded / my_sound.bytesTotal));

                              var newPos:Number = fullTime/685.5 * Math.floor(seekBar_mc.sliderSeek_mc.x * 1000);

                              pausePosition = newPos/2;

                              my_channel.stop();

                              gotoAndPlay(2);

                              my_channel = my_sound.play(newPos);   <------ Line 378

                              song_paused = false;

                              isDragging = false;

                    }

          }else

                    {

                              isDragging = false;

                              seekBar_mc.sliderSeek_mc.stopDrag();

                              pausePosition = fullTime / 100 * Math.floor(seekBar_mc.sliderSeek.mc.x * 1000);

                              //seekBar_mc.sliderSeek_mc.visible = false;

                    }

}


How can I fix this if I am streaming audio with an .XML external file which I created with Dreamweaver.


Problem #2:

Ok and onto the second problem.

Whenever I try to run my mediaplayer with the following code it was working and the scrubber bar was moving automatically with the song in my ENTER_FRAME function. Now it doesn't and when I go to play a song the trackknob is stuck in a spot along my scrubber bar like it is glitched or something???

Here is my media player and as you can see when I start the song with the playSong() function the trackknob doesn't start at the start of the scrubber bar.

Here is my enterframe function:

// Add listener to trigger [onEnterFrame] function below

addEventListener(Event.ENTER_FRAME, onEnterFrame);

function onEnterFrame(event:Event):void

{

          // Get full time

          var tallytime = (my_sound.length/1000);

          var totalmins:Number = Math.floor(tallytime /60);

          var totalsecs = Math.floor (tallytime) % 60;

          if (totalsecs < 10)

          {

                    totalsecs = "0" + totalsecs;

          }

          timerText_txt.text = ( " " + totalmins+ ":" + totalsecs);

          // End get playing time

          // Get playing time

          var totalSeconds:Number = my_channel.position/1000;

          var minutes:Number = Math.floor(totalSeconds /60);

          var seconds = Math.floor (totalSeconds) % 60;

          if (seconds < 10)

          {

                    seconds = "0" + seconds;

          }

          completeText_txt.text = ( " " + minutes+ ":" + seconds);

          // End get Full time

          /// progress bar code...

          var estimatedLength:int = Math.ceil(my_sound.length / (my_sound.bytesLoaded / my_sound.bytesTotal));

          var playbackPercent:uint = 100 * (my_channel.position / estimatedLength );

          // I want my position bar to be 200 pixels wide on completion so I multiply the percentage x 2

          seekBar_mc.sliderSeek_mc.x = playbackPercent * 2;

          seekBar_mc.sliderSeek_mc.x = seekBar_mc.sliderSeek_mc.x;

          // make the loaded progress bar that lives under the playhead progress bar grow dynamically

          var loadedPercent:uint = 100 * (my_sound.bytesLoaded / my_sound.bytesTotal);

          seekBar_mc.sliderSeek_mc.x = loadedPercent * 2;

}

How can I go about fixing this any help is appreciated thank-you.

#1:

you might have a problem in your dropIt2 fucntion:

you are using an anonymously

stopDrag()

and later on (in the same function:)

seekBar_mc.sliderSeek_mc.stopDrag();

without having insight in how your dragging/dropping is supposed to work  I can only guess that both refer to the same object(?)

if, you should use sth like:

e.currentTarget.stopDrag();

#2:

if you are using mp3 files to stream you can`t calculate the length of the sound file with this formula:

var estimatedLength:int = Math.ceil(my_sound.length / (my_sound.bytesLoaded / my_sound.bytesTotal));

since mp3 (and most lossy codecs) don`t distribute their filesize uniformly over the runtime (you would have to use a lossless format like wav for that to work)

so you will have to include the runtime of your playlists`songs into the xml files which you can then use:

var myDURATION = my_songs[mySong].@DURATION;

to start, it doesn't appear my_sound has any actual associated sound.  ie, you're not using a sound class from your library and you're not loading a sound using my_sound.

Yeah I am not loading a sound using my_sound but it have the my_sound variable to hold a sound object for my media player, I am loading sounds into my Media Player using a XML List.

// function playSong

function playSong(mySong:Number):void

{

          // extract the song details from the song XML data node

          // use the @ sign to retrieve the attributes an XML node

          // store the specific data in local variables.

          // the value of mySong will be passed to the function when we call it:

          var myTitle = my_songs[mySong].@TITLE;

          var myArtist = my_songs[mySong].@ARTIST;

          var myURL = my_songs[mySong].@URL;

 

          songTitle_txt.text = myTitle; // display song title to text field on stage

          songArtist_txt.text = myArtist; // display song artist to text field on stage

 

          // test if the channel has anything in it,

          // if it does, then stop the channel and proceed with the rest of the code

          // used by NEXT and PREVIOUS functions

          if(my_channel)

          {

                    my_channel.stop();

                    my_channel.removeEventListener(Event.SOUND_COMPLETE, onForward);

          }

 

          my_sound = new Sound(); // creates a new sound object

          my_sound.load(new URLRequest(myURL)); // load the song object to stream

          my_channel = my_sound.play(); // stream the song file into the sound channel

          my_channel.addEventListener(Event.SOUND_COMPLETE, onForward); // when current song stops, play next song

If you see in my playSong Function I have already created a new sound object and then I am loading a URL request from my XML List.

again, if

my_channel = my_sound.play(newPos); 

executes before an mp3 completes loading into my_sound, you will trigger a 2068 invalid sound error.
