We explored latency in H.264 transport for UAV/UAS and based on our analysis, much of the capture to display latency apparently comes from H.264 P and B frame reordering in a GoP, which requires

Also frame reordering (which Compressor should have) allows the  15 Jun 2014 Frame reordering is the concept of allowing frames to be decompressed in a different order than their display order. For almost all cases, leave  6 May 2013 Checking the option for frame reordering will turn on the use of B frames. Adobe Premiere Pro h.264 MOV Container. Options, Profile, M Size, B  Normal scenecut detection decides whether a frame is a scenecut after the B- frames are a core element of H.264 and are more efficient in H.264 than any  On Vimeo they say that Frame Ordering should be turned off. your preset for compressor and I got the same file size I get with H.264 at the same compr rate. Just set AsyncDepth to 1.

I know video encoder will do frame reorder for GOP with B pictures.I am not sure if my understand is correct! GOP input to encoder (it's raw data but I just ma 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. A frame or field of video is decoded from an access unit (a series of NAL units including one or more coded slices making up a coded picture). The decoding order of 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.

5.10. Frame with macroblock pairs.

4 Sep 2014 There are so many variables in the h264 encoding: key frames (all, every x frames , automatic) Frame reordering (on, off) Data Rate (Automatic, 

Frame rate: provat current och 50. Key frames: Automatic. Frame reordering: provat både på och av. Compressor  Reordering code must not mix pictures before and after MMCO_RESET.

2. Decoded frames must be outputted in presentation order (PTS in increasing). Implementation must take care of frame reordering;. 3. Do as little memory

As you might remember I decided to make decoders output frames on synchronous basis, i.e. if a frame comes to the decoder it should be decoded and output and in case when the codec support B-frames a reordering might happen later in a special frame reorderer. B-frames: B-frames are bi-directional predicted frames. As you can see in Figure 5, this means that when producing B-frames, the encoder can look both forwards and backwards for redundant picture information. This makes B-frames the most efficient frame of the three.

GOP input to encoder (it's raw data but I just map it as GOP for better understand). I(1) B(2) B(3) P(4) B(5) B(6) … If ref_pic_list_reordering_flag is 1, the reordering process is repeatedly carried out until reordering_of_pic_nums_idc is 3. Reordering process (list0; simplified) (similar for list1): Initialise a pointer (refIdxL0) to point to the first reference picture index (0) While reordering_of_pic_nums_idc ≠ 3 B-frames (frame reordering in the QuickTime dialog box) – allows B-frames (bidirectional frames). Weighted predictions (--weightp & --weightb) – allows referring to different reference frames using different weightings which are then combined, especially useful for fades.

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. h264_stream.c File Reference #include #include #include #include #include "bs.h"#include "h264_stream.h"Include dependency graph for h264_stream.c: 4:3 - 2304 × 1728 (Source Frame) = 144 x 108 (Sample Frame) = 15,552 pixels per rowNote these Source Frame resolutions are both greater than the H.264 2048x2048 limit. Video Stabilization at these higher resolutions can be successfully utilized when not associated with H.264 encoding.

If you want to save the I-frame as a JPEG image, you still need to "transcode" the video frame i.e. you first need to decode the I-frame using a H264 decoder and then encode it using a JPEG encoder. This is so because the JPEG encoder does not understand a H264 frame, it only accepts uncompressed video frames …

Surveillance Pro fully supports) with its full frame regeneration is still way better from the viewpoint of security, the industry trend seems to move towards H264. You can reorder — reposition — channels in the Favourite 3 - To shift (pan) the camera frame, press (left) or. (right). Part 10 AVC (H264), VC-1, WMV9.

Yes, I'm using libavformat for both reading and writing frames. Therefore my thought was too, that no reordering has to be performed. And now I know that's really not necessary because av_interleaved_write_frame works perfectly if the correct dts values are actually passed to it. I simply didn't pass them before and let libavformat calculate ffmpeg -h encoder=h264_nvenc.
