Hi Mikel,
I think that your problem comes from the fact that the simple.mp4 media
file only has one audio channel but the encoder requires sources with two
audio channels. You should try to either change the source file to a video
with stereo audio or else set channels=1 in the encoder.
While looking at your issue, I made some changes in the gstreamer code. If
you can, feel free to test the latest github code.
