Copied. 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.

For a given H.264 stream level and resolution, you can deduce the worst case to be a 14-frame reordering delay. That doesn't mean you need to hold the first IDR frame for 14 frames. While a 14-frame buffer would be allocated, it could be used if needed only, such that getting IDR plus a sequence of P frames that only reference the previous frame would introduce zero latency.

about POCs, IIRC the spec requires POC=0 to be true and only true for IDR pictures, but i might misremember (would have to check the spec) Makes YouTube stream H.264 videos instead of VP8/VP9 videos Try h264ify if YouTube videos stutter, take up too much CPU, eat battery life, or make your laptop hot. Avidemux and h264 (with B Frames) April 12, 2012, 02:54:23 PM I have the following problem when cutting AVI files produced with x264 (either mencoder or ffmpeg) using avidemux 2.5.6: 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. 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 elenril h264_ps: make the PPS hold a reference to its SPS. Latest commit 5e31609 on May 1, 2017 History. It represents the relationship between them more naturally and will be useful in the following commits.

H264 frame reordering

This document is informative only and readers should refer to the standard for accurate definitions of the parameters and processes described here. 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.

Prohibit reordering max_dec_frame_buffering. 0 - 3. Referencing frame number is 3 (maximum). (note 1) The intervals between pictures defines as follows.

This document is informative only and readers should refer to the standard for accurate definitions of the parameters and processes described here. The decode picture buffer described in the H.264 specification is nothing but a suggestion for buffering and synchronization purposes. It is not required to artificially delay frames to achieve conformance, unless the sequence parameter set (SPS) explicitly mentions out-of-order (B) frames are present in the stream. 0 Kudos 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. This worked as expected until I decided to implement H.264 decoder and hit the famous B-pyramid (i.e. when B-frames serve as a reference for another B-frames or even P-frames).

by maximum motion detection enabled may cause increased video frame and The higher frame size variations of H.265/HEVC compared to H.264/AVC as observed in decoding, and frame reordering to give the original frame sequence. Reorder (when the Antenna was set to Satellite): correctly. x Sound or video may not work if the contents have a standard bitrate/frame rate above the compatible Frame/sec H.264 FMO / ASO / RS, VC1 SP / MP / AP L4 and AVCHD are not. Det är väl bara att konvertera till Mov/h264 då?

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. Reordering: According to AVC spec a decoder doesn't have to return a decoded surface immediately for displaying. It's true even in This paper proposes an adaptive reference frame re-ordering for H.264/AVC based multi-view video codecs. The algorithm relies on statistical analysis of block For I/B/P encoding, picture reordering is handled in application code by assigning the picture EncodePicH264_Params: Specific H.264 per-frame parameters. 2 Jul 2016 Sometimes we might want to reorder the reference frame list just for a particular slice.
