Hi, I'm surprised by the audio artifacts when upsampling. Did you compile with the `samplerate` support?
I'll have to have a look at the encoder cutting the first seconds of the audio. We've never had such issue before and it looks like a pretty big one. One thing you can try meanwhile is to use the %gstreamer encoder and set it to encode in ogg/flac.
