    Moin,

    Did anyone use that videodecoder in the last 2 years? I'm able to compile it and run it, but i don't get a proper decoded video at all.

    Here's the command line i use to decode (from a MPEG transport stream) on both a nios system and a PC:

    mpeg2dec -t 0x45 -v -o pgm /mnt/listra.mpg

    On the nios system i get also lots of decoded pictures, but all looking totally garbled. When i compile the same decoder with the native gcc on my PC and decode the same stream, the pictures look OK.

    Other Software is running perfect on the nios system; also no errors or suspicious warnings during compilation and decoding. Exactly the same problem with newer versions of mpeg2dec.

    Any idea, what's going wrong here?

    Cheers,

    WK
