[Sugar-devel] Etoys mp3 files

[Ajay Garg]

Well, there are two different issues ::

a)
First is the data-store issue.

As seen from the logs, the (mp3) file that was opened, was present in a USB
pen drive.
ANY ENTRY, when accessed via USB-pen-drive, will give this error (i.e. mp3,
jpeg, png - any file).

CAUSE ::
=======

The code in "carquinol" package, presumes the data-to-be-accessed coming
from the journal.



SOLUTION ::
==========

As happens with all entries that are accessed from USB pen-drives, these
entries too need to be copied first to the journal, to maintain
compatability.



SOLUTION-IMPLEMENTATION-REQUIREMENT ::
=====================================

The "etoys-sugar-code" is needed, wherein a flag may be passed to
objectchooser, to copy the file to the journal if invoked from etoys; and
subsequently access the journal-entry thereafter.

Bert, we will be grateful if you could provide the code-location for this.





b)
The second issue is the sound not playing.

I ensured that the following packages were installed on my non-XO laptop
(Dell-F14-laptop) ::

* gstreamer-plugins-bad
* gstreamer-plugins-ugly
* gstreamer-ffmpeg
* etoys
* squeak-vm
* squeak-vm-nonXOplugins

Thereafter, I downloaded the following MPEG file ::
http://samples.fileformat.info/format/mpeg/sample/567fd6a0e0da4a8e81bdeb870de3b19c/DELTA.MPG?AWSAccessKeyId=0V91BEFA7GM093MEVMG2&Signature=zvF6p5NE3Jz3oSKtyw2obyPosDQ%3D&Expires=1338322225


and tried playing via "Supplies" -> "Object Catalogue" -> "Multimedia" ->
"MPEGPlayer". However, I got the same "abandon" error, with the
second-last, and third-last stack-point error as follows ::

#####################################################################
primitiveFailed
    "Announce that a primitive has failed and there is no appropriate
    Smalltalk code to run."

    self error: 'a primitive has failed'


primFileValidMPEG: aPath
    "Check to see if the file is valid"
    <primitive: 'primitiveMPEG3CheckSig' module: 'Mpeg3Plugin'>
    self primitiveFailed
#####################################################################



SOLUTION ::
=========

I guess there is still some plugin missing on my Dell laptop.
But I have gone out of ideas to try.

Bert, we will again be grateful :)




Thanks and Regards,
Ajay
