x264具有SPS和PPS的IDR存取单元 [英] x264 IDR access unit with a SPS and a PPS

问题描述

我试图在h.264中编码视频，当用苹果分析HTTP Live Streaming工具时，媒体文件分割器将通过媒体文件验证器，我在分割的MPEG-TS文件上收到两个错误

$ b $警告：媒体段包含视频轨道，但不包含任何具有SPS和PPS的IDR访问单元。
警告：7个样本（17.073％）在轨道257（avc1）中没有时间戳。

经过几个小时的研究，我认为IDR警告涉及到在正确的位置没有关键帧分段的MPEG-TS文件，所以在我的ffmpeg命令中，我设置了-keyint_min 1，以确保在每个帧的关键帧，但这没有工作。

虽然会是很高兴得到一个答案，如果有人可以说明什么是具有SPS和PPS的IDR访问单元，或者什么时间戳警告意味着我将非常感谢，谢谢。

I am trying to encode video in h.264 that when split with Apples HTTP Live Streaming tools media file segmenter will pass the media file validator I am getting two errors on the split MPEG-TS file

WARNING: Media segment contains a video track but does not contain any IDR access unit with a SPS and a PPS.
WARNING: 7 samples (17.073 %) do not have timestamps in track 257 (avc1).

After hours of research I think the "IDR" warning relates to not having keyframes in the right place on the segmented MPEG-TS file so in my ffmpeg command I set -keyint_min 1 to ensure keyframes where at every frame, but this didn't work.

Although it would be great to get an answer, if anyone can shed any light on what a "IDR access unit with a SPS and a PPS" is or what the timestamps warning means I would be very grateful, thanks.
