I'm trying to build my own application based on the UMC framework from the IPP Media Samples, v5.0.017. I can play AVI and MP4 files using simple_player, and MJPEG AVIs play fine with the UMC example (from the UMC manual). But when I change the UMC example to use MPEG4VideoDecoder instead of MJPEGVideoDecoder, the program runs, seeming to process every frame, however not one frame is decoded for rendering. I'm not surprised that the MPEG4 decoder needs to be treated differently from the MJPEG decoder, but after searching for the last 3 days through simple_player.cpp, avsync.cpp, codec_pipeline.cpp, and umc_mpeg4_video_decoder.cpp, I'm still at a loss as to what I should do to get the MPEG4 decoder to work.
Any suggestions would be greatly appreciated!
P.S. As further note for when Intel updates the documentation: FIOReader is not built by default on Linux for IA32. The UMC example depends on FIOReader and thus cannot be built without modification. Changing FIOReader to FileReader works, but I don't know what difference (if any) this makes.
