I'm trying to encode AVFrames using the GPU from C code, so I was trying to see how ffmpeg's source code was doing it and asking for a pointer on it (or its location lol). I've already encoded directly with ffmpeg (to see its working) but I need to encode random AVFrames not an entire video. Also giving a yuv420 video to the Nvidia ENC samples produces a corrupted video.
nvenc is going to encode yuv video into h264 stream, I am not sure the output format is what you want. To get "random" frames encoded, you will have to do something like GOP=1 and mark all frames key frames somehow. Sounds like you are trying to create a slide show from random frames in a video stream? Pure theory YMMV... If you want to use nvenc directly you need to transform AVFrame to EncodeFrameConfig See NVENCSTATUS CNvEncoder::EncodeFrame(EncodeFrameConfig *pEncodeFrame, bool bFlush, uint32_t width, uint32_t height) Should be able to create your own convertAvFrametoEncoded REF: convertYUVpitchtoNV12 convertYUVpitchtoYUV444 Setting ecoded->yuv[0], encoded->yuv[1], encoded->yuv[2], dstwidth, dstheight from av_frame->data[0] av_frame->data[1] av_frame->data[2], av_frame->width, av_frame->height, av_frame->linesize but I think the output will not be a "VIDEO FRAME" Thanks cco _______________________________________________ Libav-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/libav-user
