将帧推入FFmpeg缓冲区

Question

I am trying to push the extracted frames from a video (which I did using ffmpeg) into the FFMPEG buffer. I have looked into the buffer source files of ffmpeg such as buffersrc.c and fifo.c to figure out if I can do that, but I couldn't figure out. Can anyone please tell me a way to do it?

Answer 1

I think what you looking for is av_write_frame() and av_interleaved_write_frame() functions. Look for small projects on github those uses these functions, so you can see how to set up RAW stream and begin to send frames.

Hope that helps.
