I have downloaded and compiled umc_video_enc_con and umc_h264_dec_con applications from ipp-samples. Problem of wrong h264 decoding I solved as it is discussed in http://software.intel.com/en-us/forums/showthread.php?t=55409 . In result i received *.yuv file of YUV420 format (that I have specified in input parameters of application). After this I tried to encode received *.yuv file. For this I changed in h264.par only name of source file (*.yuv), horizontal_size and vertical_size (as in input file for umc_h264_dec_con.exe). After this I executed ">umc_video_enc_con h264 h264.par some_file.h264". In result I received some_file.264 that cannot be opened (error is occured while opening with WMP, for example) and cannot be viewed in GSpot.
All the applications execute without any errors (number of frames decoded by umc_h264_dec_con.exe and encoded by umc_video_enc_con.exe is equal).
Can anybody explain me what have I done wrong? Why encoded file can't be opened?
