H.264 elementary bitstream viewer

[signalogic]

can you recommend an H.264 viewer ?

[dabrain34]

YUView is a good tool

ok thanks Brain, I will try it. I also found "H.264 Analysis" (Lei Xiaohua) based on h264bitstream

You may wish to try this online parsing site: https://mediainsight360.com/, which is capable of parsing raw H.264 streams.

Below is its brief introduction.

Introduction

MediaInsight is an online visual multimedia format analysis tool designed for audio/video developers and learners. Without installing any software, you can deeply analyze the internal structure of various media files directly in your browser. Through intuitive tree structures, hexadecimal data correlation, chart statistics, and other features, it helps users quickly understand the principles of audio/video container formats and locate various issues encountered during development.

Core Features

Extensive Format Support

Supports mainstream audio/video container formats, including:

• Video Containers: FLV, MP4, fMP4, MKV/WebM, MPEG-TS, MPEG-PS
• Audio Formats: MP3, M4A/AAC
• Streaming: RTP, HLS (m3u8), HTTP-FLV
• Raw Streams: H.264/H.265 Annex B

Multi-dimensional Analysis Views

• Media Info Overview: Quickly view basic file properties such as duration, bitrate, resolution, codec format, etc.
• Frame-by-Frame Analysis: Dive into detailed information for each frame, including PTS/DTS timestamps, frame type, frame size, etc.
• Packet-by-Packet View: For formats like TS and RTP, supports viewing raw packet structures
• Container Structure: Visualize MP4 Box trees, FLV Tags, MKV EBML elements, and other container hierarchies
• Field-Level Details: Each parsed field can be expanded to view, with corresponding hexadecimal raw data highlighted

Audio/Video Preview

• Video Frame Preview: Based on WebCodec technology, supports frame-by-frame decoding and display
• Audio Playback: Supports single-frame and continuous playback, covering MP3, AAC, G.711, and other codecs

Data Visualization

• Bitrate Distribution Chart: Intuitively displays video bitrate trends over time
• Frame Interval Chart: Analyzes frame interval distribution to quickly identify stuttering or frame drops
• Frame Type Statistics: I/P/B frame ratios at a glance

Thanks Haibo, we will try it
