Playback on Amlogic TV Box


Ceth

Recommended Posts

I have a generic Amlogic based TV box running Android 4.4.2.

 

The Android app plays Live TV properly but the Android TV app (1.1.21g) halts and stutters.  It can direct play files with no problems.

 

I think the problem is related to HLS Adaptive Playback as described here:
https://github.com/google/ExoPlayer/issues/926

 

If I disable the OMX.amlogic.avc.decoder.awesome codec inside of /system/etc/media_codecs.xml, playback doesn't halt but CPU decoding is too slow and is unusable.  In another thread Luke says that HLS adaptive streaming is turned off on the server, so I'm not 100% sure if that is the issue.

 

Regardless, this looks like some buggy Amlogic firmware, but I'm curious as to why it works with the regular Android app, but not the Android TV app.  Is playback different between the two and is there a way to force the Android TV app to use a different method for Live TV?  Even with the Amlogic AVC decoder disabled, the Android app still plays the transcoded stream correctly, so it must be using a different hardware decoder entirely.

Assuming this is just Live TV, you should try again with the new version of the app that should be available very soon.
