H264 frame viewer

Three ways come to my mind (if you are looking for something free, otherwise google "h264 analysis" for paid options):

1. Download the h.264 parser from (from this thread @ doom9 forums)

2. Download the h.264 reference software

3. libh264bitstream provides h.264 bitstream reading/writing

This should get you started. By the way, the h.264 bitstream is described in Annex. B. in the ITU specs.

I've created a Web version - https://mradionov.github.io/h264-bitstream-viewer/

Based on h264bitstream and inspired by H264Naked. Done by compiling h264bitstream into WebAssembly and building a simple UI on top of it. Output information for NAL units is taken from H264Naked at the moment. Also supports files of any size, just will take some time initially to load the file, but navigation throughout the stream should be seamless.
