novice — Mon, 05 Jul 2004 13:15:18 GMT

hai ,

i passed a yuv file through an encoder and got a .mpg4 file ..i wanted to get info from the file like the header , fps etc ...i did open the mpg4 file in a text editor and found all hexa decimal numbers ...

is there anyway to decode these info .. is there anything like a bitstream parser to get the info ..i basicaly need a tool or atleast a way to decode these information from the mpg4 file ..

Do you use IPP 4.0 MPEG-4 encoder sample ? It creates only raw mpeg4 streams ( *.cmp ).

Hi,

you can use mp4decoder sample from IPP v4.0, during decoding file it create .STA file with such information.
