Once I want to encode one of the frames into a JPEG, I use the UIC library to copy that frame of RBG data int Here's the problem: I'm trying to meet a spec. for a client in which they have specified an H.264 with NO frame reordering and 44.1 kHz/320 Kbps AAC audio. I have attempted this using two methods: 1. setting up a profile within a .mov container, and 2. as a .mp4. My issues/questions are as follo Recommend:c++ - Ffmpeg decode H264 video from RTP stream very slow am and ffmpeg to decode.

An inter coded frame is divided into blocks known as macroblocks.After that, instead of directly encoding the raw pixel values for each block, the encoder will try to find a block similar to the one it is encoding on a previously encoded frame, referred to as a reference frame. If you increase the number of Key frames (reducing the interval) you are turning the H264 more Frame by Frame compression once you are sending more frames with the full image coding.

H264 frame

No other frames (P and B) can be fragmented, so if there is packetization-mode=1 in SDP , then it means that the I-Frames are fragmented, and therefore if you read 0x7C as first byte, then it is I-Frame. 2019-03-02 I-frames are the key to the compression and following P and B-frames can use the data in I-frames to save on bits. However, what I would find interesting is knowing how the encoder determines which frames should be I-frames and which should be P's and B's and pull their data from them. We have a stream that is stored in the cloud (Amazon S3) as individual H264 frames. The frames are stored as framexxxxxx.264, the numbering doesn't start from 0 but rather from some larger number, say 1000 (so, frame001000.264).
