    YV12 viewer

    Hi!

    Iím trying to display an YV12 image. I capture it from my mobile device and send to a PC via wireless. I send the data taken from the mobile device directly, without doing anything with it. Then, in the PC, I want to view it but I donít know what to do with the raw data.

    I tried to convert to RGB but when I visualize it, itís different from the image taken with the device (since I preview the image in the mobile device at the same time).

    The goal is to do a conference system between the mobile device and the PC using c++. Iím using DirectShow too, if itís of any help.

    Thanks.

    this might help. The format you mention looks aggravating, to say the least, but it *is* an open format and many sites on the web describe it, this one had source code.

    Thanks for the reply but it's just the other way round...I would need conversion from YV12 to RGB but I wanted to know if I can give the renderer the YV12 raw data directly without any conversion, since the conversion doesn't work for my application (I don't know why not).:(

    you cannot just display this format in directdraw - it is a form of mpeg compression (its the basis for several codecs) so you will have to turn it into rgb *or* embed an mpeg player and a find a codec that can handle this format.

    My bad, I thought that link had both to and from conversions.

    As for understanding the format YUV formats, this page might be of value: http://www.fourcc.org/yuv.php.
