That's bad... The driver contains file sp5x_32.dll which is registered in system.ini file as [drivers32] VIDC.SP54=SP5X_32.DLL Seems that the codec is called SP54 - hope that it's used to decompress the data. > All I can do is to code the driver and let you or anyone find the > decompression function... Maybe we can dump some data, create AVI file from that and try to decode the file using that codec. -- Ondrej Zary -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
