With the DVB-T2 channels in Germany, which use the AAC LATM 5.1 codec, the audio stutters.
The latest version of KODI nightly build, however, works without problems.
And even the latest version of KMPlayer from the Playstore processed AAC LATM 5.1. without stutters.
Both kodi and kmplayer are using the ffmepg library and both are working.
By the way:
The LAV codec in Windows is also based on ffmpeg and had the same problem. This was already fixed in June in the release 0.7. The reason for the audio problem should be Program Config Elements (PCE) in the AAC stream.
Maybe these hints help in solving the problem.
It is a pity that only the MXPlayer has problems with AAC LATM 5.1.
MXPlayer is my favorite player. I therefore hope for a solution of the problem.
