Hi Vlad,
Thank you for ur reply. Now i have compiled
apiexample.c/output_example.c and also finished my program
test_encode_decode.c to encode and decode YUV video stream via mpeg4
encoder/decoder,
and it works fine.Instead of parsing the local file by calling
av_open_input_file and so on, my program can deal with the realtime video
stream (get from DVR) by directly calling avcodec_encode_video and
avcodec_decode_video methods. But now , i encounter a problem: when i use my
program(the prev program: test_encode_decode.c) to decode H264 video stream
using h264 decoder, it will be OK on windows using MFC, but NOT in linux.
The two platform has the same codes. After debugging for a long while, i
still donnot know why. Can somebody guide me how to deal with this?
Best Regards,
xutm
