No Audio To Transcode Causes Video Stream To Freeze
We've been running on Wowza 3.6 for a while with no issues. The sources streams are H.264/Speex coming from the Flash player. I am transcoding them with audioonly - using passthrough for the video and AAC for the audio. The output Flash stream plays fine as does the transcoded stream for iOS.
After upgrading to Wowza 4.1.1 we've discovered a strange issue. The issue only seems to affect the iOS stream. When there is audio in the source stream, everything seems fine, but as soon as the person stops talking and there is no audio, the iOS stream freezes. Then it picks up again when the person starts talking.
Since I couldn't copy the configuration files I'm guessing there is something in this new version that is not configured correctly. I'm running the live-lowlatency StreamType and the only packetizer is the cupertinostreamingpacketizer.
