How to write a Live555 FramedSource to allow me to stream H.264 live
22 juillet 2015, par GarvielI’ve been trying to write a class that derives from FramedSource in Live555 that will allow me to stream live data from my D3D9 application to an MP4 or similar.
What I do each frame is grab the backbuffer into system memory as a texture, then convert it from RGB -> YUV420P, then encode it using x264, then ideally pass the NAL packets on to Live555. I made a class called H264FramedSource that derived from FramedSource basically by copying the DeviceSource file. Instead of the input being an input file, I’ve made it a NAL packet which I update each frame.
I’m quite new to codecs and streaming, so I could be doing everything completely wrong. In each doGetNextFrame() should I be grabbing the NAL packet and doing something like
memcpy(fTo, nal->p_payload, nal->i_payload)
I assume that the payload is my frame data in bytes ? If anybody has an example of a class they derived from FramedSource that might at least be close to what I’m trying to do I would love to see it, this is all new to me and a little tricky to figure out what’s happening. Live555’s documentation is pretty much the code itself which doesn’t exactly make it easy for me to figure out.
