[Question] iPad Live TV not working. (1 Viewer)

[justinbyoung]

I can't get live TV working properly at any quality setting on our iPad 3 using MPExtended 0.5.4. I get a still frame and stop start distorted audio. Other sources are fine. I can play back a transcoded 1080p mkv without a problem. Also I can play back live TV on my Android phone via Ampdroid without a problem.

My server is a 4 core i5, so it shouldn't be a horsepower problem with transcoding, especially as playback on Android is perfect. The iPad is running iOS 7.02, but I also had the problem on iOS 6.02. Any ideas what might be causing my iPad problem?

I have included the relevant service.log entries below.

I don't know the exact cause of your problem but I had a similar issue with my iPhone.

Here's what I did - add a custom streaming profile for live tv.

Go to "C:\ProgramData\MPExtended" and open "StreamingProfiles.xml" in a text editor.

Add the following lines to the file. This should be inserted after the end of one of the other profiles, look for a </TranscoderProfile> and put it after this. Select this profile via the web interface for live tv.

    <TranscoderProfile>
      <Name>iOS TV Streaming</Name>
      <Description>HD-quality HTTP Live Streaming profile</Description>
      <HasVideoStream>true</HasVideoStream>
      <MIME>video/MP2T</MIME>

      <MaxOutputHeight>360</MaxOutputHeight>
