[video_player_avplay] AudioTrack channel issue

[mhoeckner]

Dear Samsung Team,

in our MPD (attached) we got three audio tracks. Two for 'de' and one 'en'.

1. de audio 2.0
2. de audio 5.1
3. en audio 2.0

video_player_avplay identifies the tracks with =>
[I] flutter: trackId: 0 | language: de | channel: 2 | bitrate: 210765
[I] flutter: trackId: 1 | language: de | channel: 0 | bitrate: 361898
[I] flutter: trackId: 2 | language: en | channel: 0 | bitrate: 210765

Shouldn't it be
[I] flutter: trackId: 0 | language: de | channel: 2 | bitrate: 210765
[I] flutter: trackId: 1 | language: de | channel: 6 | bitrate: 361898
[I] flutter: trackId: 2 | language: en | channel: 2 | bitrate: 210765

Since the label of mpd audio track is missing, we have to check if there is a 5.1 available with the help of bitrate - that is not very reliable from my point of view.

What does 'channel' mean?

Thank you in advance,
best regards
Markus
