    Re: Efficiency of playing sound

    Since you have 100 samples played randomly don't bother trying to keep old Players in PREFETCHED or REALIZED states when they've played their content (the first time).

    In order to minimize memory...

    Re: J2ME: Audio uplink during an active call

    As noted in my other message, you can't access phone audio via standard J2ME interfaces.
  3. Re: how to interject stored sound bites into the live voice channel

    Are we still talking about access to sound in a phone call? That part hasn't changed over the years; the Java application doesn't have access there.
  4. Re: Developing a sound editing mobile phone s'ware

    Sound editing in J2ME is limited by the fact that there's no way to cut and concatenate media clips, or to access the media in decoded format, whether they are audio or video. If the editing...

    Re: Playing DTMF tones with nokia 3410

    Unless you generate wave files yourself within the application.

    EDIT: Of course, that is still not enough to pass the tones to the phone call.

    Re: Rounding of mediatime in different devices

    For starters, don't try to map your text events to media time with equals. Instead of "myTimeStamp == mediaTime" use "myTimeStamp <= mediaTime".

    Reducing the polling interval of the media time...

    Re: algorithms

    As said, HW implementation uses some specific multimedia accelerator or DSP instead of general purpose CPU to perform the media processing. Usually the algorithms for them are implemented by the...
  8. Re: can't play file from inputstream (no ending)

    There's nothing wrong with the file itself. The implementation probably reads the whole content during realize or prefetch. If if can't get the EOF properly then that might be the reason for the...

    Re: Mixing of two mp3 files using j2me......

    If the sampling rates of the raw PCM are the same then a simple sample by sample addition should do the work. Divide the result by some suitable constant if the addition overflows.
  10. Re: Can I draw any thing over the video capture area?

    No, you can't.

    JSR-234, Advanced Multimedia Supplements (AMMS), gives you tools to get Images on top of the video. AMMS is quite new specification and not available for any products yet.

    You...

    Re: how to use DataSource in MMAPI

    DataSource is a way to implement your own protocol handler or to create the content on the fly. In order to use it you will implement SourceStreams and DataSource yourself to decocde the content.

    The InputStream does not have a format of its own. Its the content, for instance MP3 file, in a stream.

    Re: Mixing of two mp3 files using j2me......

    Being able to use the same TimeBase for different players and content types is not directly related to mixing. Mixing works, if it works at all, even if you don't set the TimeBase.

    Looks like the device supports only one sound playing at a time. There's no way to get around that restriction.

    MMAPI 1.1 is binary compatible with MMAPI 1.0. The differences are in the documentation, not in classes or methods.

    MMAPI 1.1 mainly enhances the locators you give in createPlayer.

    How long is the wav file? If it's 20kb it shouldn't last more than 2.5 s. If you transfer the wav file alone to the phone, does it play?

    Random.nextInt() does not take a parameter.
