How to decode using libx264 package?

Question

Environment: Ubuntu 16.04, package libx264-148

I am looking at decoding some x264-encoded data using libx264 library. I found a sample at https://code.videolan.org/solaris/x264/raw/7d35ba6bf080610d8f144f4270e961c69ba14f1c/x264.c. It is using APIs such as x264_decoder_open and x264_decoder_decode. However, when I examine /usr/include/x264.h, I see APIs only for encoding such as x264_encoder_open and x264_encoder_encode. There are no APIs for decoding. I am wondering if I am missing something. Are we supposed to use the same APIs for encoding as well as decoding? Also, pointer to any code sample will be highly appreciated. Regards.

PS: It is a similar issue with x265.h as well.

You're not missing anything. x264 doesn't decode, its an encoder only

Thank you szatmary. Is there any alternative library to decode? What is ffmpeg using? – Peter May 05 '17 at 03:21
Ffmpeg uses ffmpeg. They wrote their own. – szatmary May 05 '17 at 03:21
