The stream was generated with the Mainconcept AVC encoder and uses SEIs for frame timing, along with reflist reordering, so its a bit of a mess, but it is spec-compliant. h264 demuxSEIs for h264 demuxer doesn't support SEIs frame timing, → h264 demuxer doesn't support SEIs frame timing, comment:2 Changed 13 years ago by Jean-Baptiste Kempf. 2014-06-15 · Frame reordering is the concept of allowing frames to be decompressed in a different order than their display order. For almost all cases, leave this box checked for H.264 encoding. Some more advanced compressors use “frame reordering” to more efficiently represent movie data. Frame reordering is the concept of allowing frames to be decompressed in a different order than their display order.

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. Note that B-frames are not available when producing using H.264's Baseline h264_stream.c File Reference #include #include #include #include #include "bs.h"#include "h264_stream.h"Include dependency graph for h264_stream.c: There are so many variables in the h264 encoding: key frames (all, every x frames , automatic) Frame reordering (on, off) Data Rate (Automatic, restricted to x) Optimization(download, streaming, CD) and none of them seem to equate to anything in the literature about how long GOP codecs are specified. 25fps, Keyframe every 5 frames, 40000kbits/sec, download optimised is my best attempt, but 2021-04-09 [h264 @ 0x24c3100] number of reference frames (1+1) exceeds max (0; probably corrupt input), discarding one [h264 @ 0x24c3100] concealing 24 DC, 24 AC, 24 MV errors in P frame [h264 @ 0x24c3100] long_term_pic_idx overflow Input Frame structure frameFieldMode H264 Codec parameters Reordering done by NVENC SDK Encoder Order : I P B B P B B Reordering done by Application .

For our intended destination of the web, this is not an issue. If you are creating QuickTime movies for the iPhone or ATV, which have less processing power than our Macs, you would want to uncheck the 'Frame Reordering… Add H264 bitstream rewriting to limit frame reordering marker in header The VUI part an SPS may specify max_num_reorder_frames and max_dec_frame_buffering. These may cause a decoder to buffer a number of frame prior allowing decode, leading to delays, even if no frames using such references (ie B-frames) are sent. 2020-06-02 2010-11-02 2010-11-18 elenril h264_ps: make the PPS hold a reference to its SPS.

It is by far the most commonly used format for the recording, compression, and distribution of video content, used by 91% of video industry developers as of September 2019. B-frames: B-frames are bi-directional predicted frames.

For almost all cases, leave this box checked for H.264 encoding. Does this version of the H.264 decoder do frame reordering ? I didn't have any problem on H.264 Main profile video with the H.264 decoder from the 5.0 version. Now, with the same H.264 main profile streams, and changing the decoder version to 5.1, the first displayed images are not reordered as the were with the 5.0 version which was playing fine.

Then the frame, for which frame_num = last_reordered_frame_num + offset, is put in the n th place in the list, while the rest is shifted. The initial value of the last_reordered_frame_num is the frame_num of the slice, and it is updated with each reordering. We also have Quicktime’s native h.264 codec. This codec is limited to the Main profile and Premiere Pro limits Quicktime to single-pass operation. Checking the option for frame reordering will turn on the use of B frames.
