[FFmpeg-devel] [PATCH V1 2/6] lavc/aac_adtstoasc: use initialized var for avpriv_mpeg4audio_get_config

[Jun Zhao]

From: Jun Zhao <barryjzhao at tencent.com>

avpriv_mpeg4audio_get_config will use MPEG4AudioConfig.chan_config to get
the MPEG4AudioConfig.channels, but if we use a uninitialized variable,
we will get an indeterminate channels, add an explicit initialization
for this case.
