    Yes, in theory OpenML does what you want.

    The only issue is that you must have an OpenML module (like a driver) for your particular hardware. This module would have to be provided by your hardware...

    I haven't looked at all that is available; I know that for AVI files, there is an API built into Windows. And I think (but I'm not certain) that the QuickTime API from Apple handles MPEG.

    Yes, UST is implemented. However, the SDK only comes with a software UST source (it relies on the system clock, which is not accurate enough to be compliant with the spec). For a proper UST source,...

    Re: Avi and mpeg

    OpenML is an I/O API; it interfaces with capture and playback boards to capture live video feeds into memory buffers, or play back from memory buffers.

    It is not a File I/O API. It has no...

    Re: OpenML SDK 1.1 now on sourceforge

    The release notes are not yet ready.

    The changes are very minor -- mostly, they involve the new copyright notices (that go along with the open-sourcing).

    I believe I fixed a couple of the bugs...

    Re: QT

    I haven't actually tried, so perhaps there are issues I'm not considering, but in theory OpenML should be independent of your choice of UI toolkit. Unlike OpenGL, which interacts with the display...
  9. Re: OpenML, Sourceforge and Unsupported Press Release

    The OpenML SDK will indeed be released as open source, on SourceForge.

    Due to a variety of small delays, the release has not happened as soon as we hoped, but it is on the way.

    Thank you for...

    Re: OpenML vs OpenCV

    I've just taken a quick look at OpenCV, and it seems to me that it is focused on image processing -- not on image acquisition. If this is the case, you could use OpenML to capture your video, and...

    Re: PARAM_ENUM_NAMES length

    Indeed, this is an inconsistency between the spec and the current sample implementations. I'll check to see which we should be fixing.

    Thank you for pointing this out.

    Re: ML on Windows CE

    Yes, I'd also love to hear about ports to Windows CE!

    Out of curiosity, are there any Windows CE devices that can do video I/O, or are we mostly talking about audio here?

    Re: Playing multiple voices

    John,

    this is a good question. At first glance, it would seem that ML does not support multiple voices and hardware mixing (but I'm no audio expert, so I could be wrong). In this case, the...

    Re: A Basic question

    Hi John,

    If I understand correctly, you want to copy files from a disk (i.e.: file-system operations, rather than video capture operations), and then "serve" them to subscribers (over the Web,...

    Re: Supported Hardware

    I don't have a definitive list of manufacturers either, unfortunately. For sure, SGI and DVS support ML, I'm not sure about anything else.

    For a board to be supported *natively*, it definitely...

    Indeed, this is (another) bug. Note however that the di/dd interface is not actually part of the ML spec -- it is part of the reference implementation, for which the API is not set in stone the way...

    Re: ML_OPEN_XCODE_MODE default

    Jarno:

    yes, I see what you're saying. This certainly seems to be a bug -- it should be possible to change the default mode; it shouldn't matter that one enum is "less than" the other.

    It would...

    Re: nullxcode test failure

    I don't think this is a bug in nullXcode.

    It is more likely a bug in the test program, which has perhaps not been kept up to date. In this particular case, I don't know why the length of the UST...

    Re: ML_OPEN_XCODE_MODE default

    Hello Jarno,

    There should be nothing preventing you from choosing a different xcode mode -- as long as the device (transcoder) you are using supports the mode. I assume you're trying the nullxcode...

    Re: How to open ML_SDK_installer.wip

    I'm a bit confused as to why you need the installer project? That project is used to prepare the SDK for distribution, producing the package that you have (presumably) installed on your...

    We're talking 'video monitor' here, not computer monitor. If your video monitor is NTSC (525-line), it will have 486 active lines, no more. If your video monitor is PAL (625-line), it will have 576...
