Pandora Timeshifting App: Main Discussion Thread


Recommended Posts

Here's a bug (I think) for someone to look into. In Mp3Processor.java, in function joinMp3s, the accumulated file array might be wrong. The "for" loop exits with a 'LOG.debug("no more mp3 found in dir"); return;' when a non-directory, non-mp3, non-recent file is found. If that happens before the plugtmp (or plugtmp-x) directory is processed in the "for" loop, the function doesn't recurse and process that directory. That can be seen in the log file output when the same file is saved multiple times with the wrong filename and tagging. The determination of "non-recent" is in isFileRecent, where it appears that "recent" is within 3 hours. When you delete the plugtmp (and/or plugtmp-x) directory and start clean, you can see the problem happen 3 hours into the running of the program.

Until fixed, I think stopping the program, cleaning up, restarting, should eliminate that problem.

Comments? Am I all wet?

Actually that would explain a lot.

What if it deleted the files once it moved them? I mean really if it can't move them while they are playing then it won't remove anything being played, right?

Hi,

Carmen describes exactly my problem with the wrong MP3 file names.

Thanx for checking the sources.... (I can't do this...)

But that can also happens after 6 files ... That mean it bugs up in 30 minutes.... I've tested it and stopped recording after that.....

Any program fix for that ? Pandora 7.4 Omega ?

Without that fix I can't use the jar... :cry:

Folks .. Proof your recorded files !!! Often you'll find e.g. an Audioslave Track and in real it's Stereophonics or so.... Not so funny :cry:

Just have a look at the recorded files & listen to them..... You'll find the differences !!!

I'm having a problem with my install. The app loads, but the pandora player doesn't. I followed the install instructions 100%. though i had to re-install flash 8.

You downloaded the wrong version. Scroll down the N00bs guide to the SECOND set of download and install instructions and try again.

Thanks alot, that fixed things up. :D

great program, excellent work, until...oops. i mistakenly upgraded to flash player 9, and realized too late this is a no-no. i read back thru the thread, uninstalled 9, reinstalled 8, reinstalled pandora's jar, etc. tried everyting i could think of, but when mozilla opens, no player opens. any suggestions? any chance program will be written for palyer 9?

You can download Flash Player 8 HERE

But first you have to unistall Flash Player 9 by downloading THIS

Hope this helps cuz this is a great little app :D Props to you MrDave2176!

I just maintain and try to debug what we got. The real props go to the folks who coded the original and have made verion-worthy leaps in the code.

I figured out that last.FM has changed their sight ever so slightly . So that has broken all of the Picture, fan, and bio links.

I've got it fixed, but I'll be putting in some other fixes to the skins files and I am looking at this 'recent' file' thing.

you can look at that part for yourself. THis is in Mp3Processor.java

    public static void joinMp3s(List<File> mp3s, File lookinDir) throws IOException {

        LOG.debug("n***processing directory: " + lookinDir.getName() + "***n");

        File[] files = lookinDir.listFiles();

        sortFilesByLastModified(files);



        //uncomment to print files in each working directory

        //printFiles(files);



        for (File currentFile : files) {

            if (!currentFile.isDirectory()) {

                if (isMp3(currentFile)) {

                    LOG.debug("mp3 found adding currentFile: " + currentFile.getName());

                    mp3s.add(currentFile);

                } else {

                    if (isFileRecent(currentFile)) {

                        LOG.debug("recent non mp3 file found: " + currentFile.getName() + " - will continue to next file");

                        continue;

                    }

                    LOG.debug("non-recent non mp3 file found: " + currentFile.getName() + " - will continue to next file");

                    continue;

                }

            } else {

                joinMp3s(mp3s, currentFile);

            }

        }

        LOG.debug("n***Finished directory: " + lookinDir.getName() + "***n");

        return;

    }

What I've done is forced it to recurse through all of the directories before giving up. This is less than efficient, but until I hear a better idea, that's what I'm working with.

I just cannot get this to finish working for the life of me. When I go to it, and have it on cruise control, it never seems to finish downloading a song. It just says "Fetching ID3 information and tagging MP3 for artist." and then never goes past that until that song ends and it goes into the next one.

I am looking at this 'recent' file' thing.

        LOG.debug("n***processing directory: " + lookinDir.getName() + "***n");

...

        return;

    }

What I've done is forced it to recurse through all of the directories before giving up. This is less than efficient, but until I hear a better idea, that's what I'm working with.

Here are some additional thoughts:

1-I "solved" the problem temporarily by creating another account under XP (pro version, don't know if it makes a difference), and running JUST this app there. (I.e., running just the jar and the firefox localhost page, no other programs, no other tabs/windows in firefox.) It gets its own temp dir and the "recent"-checking code should be OK there. The app continues to run even after switching back to another account.

2-I suspect that the reason the "recent" code was created was to speed up the search of the TEMP directory. I thought that shouldn't be too much of a problem. I looked at my TEMP directory and found almost 1000 files there. Even that many may not be much of a problem, I don't know the timings involved. But, it was very easy to delete most of the files there without affecting anything, reducing any potential problem. So, people might take a look at their TEMP directories and clean things up.

3-The orginal joinMp3s() might be OK with a slightly different isFileRecent() function. Instead of:

    private static boolean isFileRecent(File file) {

        Date now = new Date();

        Calendar calendar = Calendar.getInstance();

        calendar.setTime(new Date(file.lastModified()));

        calendar.add(Calendar.HOUR, 3);

        return now.before(calendar.getTime());

    }

How about something like:

    private static boolean isFileRecent(File file) {

         static Calendar calendar_to_compare = NULL;

        static Calendar calendar_this_file = Calendar.getInstance();

        boolean bool_return_value = TRUE;



        if ( calendar_to_compare == NULL ){

            calendar_to_compare = Calendar.getInstance();

            calendar_to_compare.add(Calendar.HOUR, -1);

         } else {

            calendar_this_file.setTime(new Date(file.lastModified()));

            bool_return_value = ( date_to_compare.compareTo(calendar_this_file) < 0 );

        }

        return bool_return_value;

    }

(My java's probably not correct, but hopefully you get the idea.) This will "break" if Pandora ever starts up and waits over an hour to create the plugtmp directory, but should limit the number of files inspected.

same as mine and when i even pause the song so it dosent go to the next it will finally say it saved. When i go to play the song its a completely diffrerent song and its always 1.10 mb!!!!! pissing me off. i put cruise control off and do im manually around the middle/end of song. any ideas dave?

I am not having this problem, so it is tough to say why it it is happeneing to you. Try turning off the cddb lookup and see if it is still doing it. Then I'd know what is where the problem lies.

Hi, I've been using this app for a couple days now, but just today it stopped working for me. Before that, except for a few occassional bugs it worked perfectly fine. Now I click on the batch file and everything on the page loads but the pandora player itself, making it useless. I have the latest version of java, and have flash 8, and the only changes I've made are switching from zonealarm to kaspersky and a few extra plugins and CSS changes on firefox. I thought it might be the kapersky that was doing it so I disabled it and tried it again a couple times but it still didnt work, so I have no idea what to do. Any help would be greatly appreciated. :)

When installing the newer yahoo messenger be careful it seems to

want to install flash 9 even when version 8 is installed. I think that

is what caused my initial problem previously posted, when i had to

search for the removal and installation if flash 8. :?

still only grabbing 1.10 mb of song and labeling wrong.

nanajeebus what version of are you using? It sounds like you are using an older version (below 7.3)? Find the latest and try that version

I wasn't sure, so I just 'uninstalled' my current version and installed the new one, 7.3.1, but i'm still having the same problem.

everything is ok, i just report this error:

"unable to retrieve bio from last.fm: Connection timed out: connect"

i'm behind a firewall, does it matter? even if pandora is working?

there is a way to change the time out value for sending info to las.fm?

Last.fm has changed it's site and so until i get the newer version up the lastfm bio lookup stuff is not working.

I THINK this is the only file with changes, I could be wrong, but feel free to try it.

running 7.3, with flash 8; have tried reinstalling several times...still run into same problem, which has only started happening recently.

run bat file, app loads. grab files sits in "fetching" mode until song is over and next song begins. sometimes "not running firefox" error appears, sometimes not. while second song is playing, either grabs first song listing first song as grab, or grabs first song listing second song as grab. in either case, song is only couple hundred kb, about 1 min.

even after running thru several songs, not always running properly.

anyone else get this? any suggestions?
