--- Comment #1 from Philippe Normand <pnormand at igalia.com> ---
m_audioTracks looks empty? This is with a RelWithDebInfo build:

(gdb) f 2

(gdb) p track
$1 = <optimized out>
(gdb) p m_audioTracks

$2 = {m_impl = {static m_maxLoad = 2, static m_minLoad = 6, m_table = 0x0, m_tableSize = 0, m_tableSizeMask = 0, m_keyCount = 0, m_deletedCount = 0}}
(gdb) p streamId
$3 = "511baabfffee5fa8069fe40b80215508"
