problems running simple_player.exe

Hi,
I was able to compile the application simple player on VC++ abd able to generate simple_player.exe. while trying to run this application with an mpeg1 input like:

simple_player.exe mpeg1mp2.m1v -p perf_data.txt -vfw


i get the following prints:

Usage: ????????e???????p????????w???????????
[-s(ilent)]
[-b(lind)]
[-n(atural temp)]
[-u(nrendered audio)
[-d(einterlacing)
[-i
[-t
[-p (must be in quotes if it contains gaps)]
[-v
-in the case of -vfwf>]
[-a
-in the case of -afwf]
[-f]
(-l |stream>(must be in quotes if it contains gaps)



which means probably that the options are not correct from my side. i am attaching the input bitstream for your reference mpeg1mp2.m1v.

A quick one from senior members would be really appeciated

Hi abhishek,

The UMC simple_player sample utilizes the UMC decoders, where I dont see any existing decoder for MPEG1 video.

Did you try an MPEG-2 stream or other video format supported by the UMC, in order to validate the built simpl_player.exe you have?

Please refer to the readme.htm, included within the simple_player project directory, and locate the current supported formats by the application; also, check the codec folder to see the full list of the sample implementations, UMC currently have.

Regards,

Hi,
thanks for the reply.

Although MPEG1 decoder is not specifically listed in the readme doc of the application but the file umc_mpeg1_dec.cpp in the mpeg2_dec/src folder. even otherwise i am pretty sure that the mpeg1 decoding is done by ipp although the code is present under mpeg2_dec folder.

Hi abhishek,

Are you building for UNICODE character set? If so, try another option, and let me know how is it going then.

Hi abhishek,

Its good to know that your problem got solved.

Also, Im curious to know about the MPEG-1 decoding results with UMC, if you dont mind to share this result as well.
