Hi Dolevo Jay, i have a quastion for you: also i am writing a C program that use h264 to encode video read from file.
I saw the example decoding_encoding.c that generates a video from dummy pictures... but how do I replace this part and read and encode my video? Can you help me, there are other examples or books available? Thanks!!! 2013/10/14 Dolevo Jay <[email protected]> > Hi all, > > I have encoder and decoder application in separate projects.
