Bug#756329: vlc: Fix usage of AVFrame to avoid crashes

[Andreas Cadhalpun]

Package: vlc
Version: 2.1.4-1
Severity: important
Tags: patch

Dear Maintainer,

in modules/codec/avcodec/audio.c one finds:
     AVFrame frame;
     memset( &frame, 0, sizeof( frame ) );

According to the documentation of libavutil this is wrong:
"sizeof(AVFrame) is not a part of the public ABI, so new fields may be 
added to the end with a minor bump."

This code will crash, when used with a different AVFrame at runtime than 
was available at compile-time.

The attached patch fixes this problem.

Best regards,
Andreas
