For live events a feed is provided via HD/SDI (embedded audio), which is passed to two VBrick H.264 encoders that send the RTMP streams to Wowza 3.1.1. The stream is then viewed using jwPlayer 5.9.
If I set the audio sample rate to 48Khz in the encoders we experience audio syncing issues, but at a perfect pitch. If I set the audio sample rate to 44.1Khz, the audio syncing issues no longer exists, but the pitch is much lower and very obvious.
Any ideas as to how I can solve this.
