QUESTION

Does RTMP support the Display Orientation SEI Message in h264 streams?

Asked 2020-May-30 at 00:32

I'm streaming video h264 video and AAC audio over RTMP on Android using the native MediaCodec APIs. Video and audio look great, however while the video is shot in potrait mode, playback on the web or with VLC is always in landscape.

Having read through the h264 spec, I see that this sort of extra metadata can be specified in Supplemental Enhancement Information (SEI), and I've gone about adding it to the raw h264 bit stream. My SEI NAL unit for this follows this rudimentary format, I plan to optimize later:

Does RTMP support the Display Orientation SEI Message in h264 streams?

RTMP is unaware of the very concept. from RTMPs perspective, the SEI is just a series of bytes it copys. It never looks at them, it never parses them.

The thing that needs to support it, is the h.264 decoder (which RTMP is also unaware of) and the player software. If it is not working for you, you must check the player, or the validity of the encoded SEI, not the transport.

According to the the ffmpeg wiki, the way you described is exactly how it is intended to be done. To implement this you should write each image from your array into a single file according to the described naming conventions. I don't know if this will help with your performance issues though. Writing the images to files can be done following this answer:
