Charles thanks for your answer. I've already compiled using the Nvidia SDK, the thing is that SDK example code is.. uhm.. so I was trying to read FFmpeg's source code instead looking how were you using it. Reading the nvenc.c code and correct me If I'm wrong but setting up an AVCodecContext, calling ff_nvenc_encode_frame with a frame and receive a packet to write would do it? _______________________________________________ Libav-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/libav-user
