On the other hand, if it is a non-reference field / frame / picture, nal_ref_idc is equal to 0. For any non-zero value, the larger the value, the more the importance of the NAL unit. In this case, it is equal to 3 (0x11) and is a reference field / frame / picture (In fact, it’s a SPS. I’ll tell you more later).

A frame is a complete image, A frame used as a reference for predicting other frames is called a reference frame. Frames encoded without information from other frames are called I-frames.

Mar 27, 2020 I have read online that .h264 sometimes drops frames. With raspivid you can capture the timestamps of each frame as well by using the -pts 

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. It does not necessarily means more quality, as long as all frames are being received they should be able to allow the decompression to work properly and the playback quality will be very similar at human view. 2016-11-25 · Download H264 Stream Analysis for free.

H.264 · I-frames are index frames that consume the most amount of data - because other frame types reference back to them, which in turn means a video has to 

As such, they are only used in inter-frame compression techniques. In older video encoding standards, such as MPEG-2, only one reference frame – the previous frame – was used for P-frames.Two reference frames (one past and one future) were used for B-frames 1 IntroductionThis document introduces the parameters and processes involved in managing coded frames within the H.264/AVC standard. This document is informative only and readers should refer to the standard for accurate definitions of the parameters and processes described here. 2015-04-22 iFrame is a digital video format developed by Apple.It is based on existing industry standards, such as AVC/H.264, AAC and QuickTime, and can be used with compatible Mac and PC applications..
