Subject: AVRCP: Get track duration using GetPlayStatus command
X-Git-Tag: android-x86-4.4-r3~8565
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=b926af1c4f4b58fbddd846db4b0b5fb1070cab92;p=android-x86%2Fexternal-bluetooth-bluez.git

AVRCP: Get track duration using GetPlayStatus command

Some stacks, notably broadcom, don't send track duration together with
other metadata so it has to be set using GetPlayStatus.
