Yeah I finally got the decoder working on a frame to frame basis and got rid of the constant errors, at least as long as the stream is good.
I'm confused what you mean by "The encoder expects NAL units". I'm piping raw video data (via ffmpeg using yuv4mpegpipe format) into x264 which seems to work. Two questions for you? 1) Is live555 suitable for lossy physical layer transmissions or only for situations with a working UDP or TCP network? 2) Sometimes the video gets so corrupted over the wireless channel that the decoder seems to get stuck printing a constant series of errors and doesn't recover, even if the channel improves. Do you know of a way to restart or flush the decoder some way, or another way to get around this?
