The first thing to do would be to figure out what is the part of code that is the bottleneck which is slowing down the video analysis. The function takes a CFDataRef containing the compressed video frame and a frame time (provided by the client from the bitstream) which is packaged in a frame info dictionary. 1 frame per second would be -r 1, one frame every four seconds would be -r 0. Reference frames is the number of frames that the encoder can search for redundancies while encoding, which can impact both encoding time and decoding complexity; that is, when producing a B-frame or P-frame, if you used a setting of 10, the encoder would search until it found up to 10 frames with redundant information, increasing the search time. the first frame of the video would be at index 0 I want to know the index of each key frame in the video frames. 264 video on iOS. ffmpeg will decode a/v, and be much slower than ffprobe (you can speed it up slightly if you disable audio -an) you can use ffprobe to output the framecount directly, but they are not decoded, thus essentially instant. It can be done with local files quite easily (just seek frame that is N-1 where N is current frame), but it won't work in many streaming scenarios (unless you buffer frames, but that won't be memory efficient with HD files). Each subframe has its own header that specifies how the subframe is encoded. When we're ready with decoding all the frames (note that this code doesn't decode any postponed packets), we cleanup using av_parser_close() and avcodec_close(). Does anyone know how to decode H. h264 / AVC Codec with all the usual information was returned to me along with the structure of the h264 video. 264 video in slice mode, how will I now, when a single slice is ready (for example to further processing)? As I understand vpu_IsBusy() and vpu_WaitForInt() are useful only when I want to encode frame by frame (not slice by slice). Reading one frame with this method takes 2 milliseconds on my computer. The frame is encoded by using only Intra Frame Prediction. 264/MPEG-4 AVC (Part 10) standard. I have accomplished this for JPEG streams quite easily and now I have the task of MPEG4 and h264.
