Unsupported presentation (0x20400003)

Question

so I'm trying to get a really simple livestreaming system running through Azure Media Services. I've got ffmpeg installed on a Raspberry Pi w/ a USB camera, and I'm just trying to get the camera feed received through Azure so I can start tinkering with the Media Player. The ffmpeg command appears to run without a hitch, but whenever I attempt to preview the stream, I get a the following error:

"The video playback was aborted due to a corruption problem or because the video used features your browser did not support. 0x20400003"

The 0x0400003 part of the code is listed in the docs (http://amp.azure.net/libs/amp/latest/docs/index.html#error-codes) as meaning the presentation of the video is not supported, but I can't find what that actually means in terms of what's wrong.

I'm using the following ffmpeg command for encoding,

ffmpeg -v verbose -framerate 30 -r 30 -i /dev/video0 -vcodec libx264 -preset ultrafast -acodec libfdk-aac -ab 48k -b:v 500k -maxrate 500k -bufsize 500k -r 30 -g 60 -keyint_min 60 -sc_threshold 0 -f flv rtmp://{Azure channel address}/channel5

which results in the following output:

I'm not sure if the header errors are significant, as the program continues to run as expected, but please let me know if there's anything here that's blatantly an issue, or whether there's a meaningful explanation for what the presentation issues are.
