[Gnash-commit] [patch #8747] Patches to fix 8-bit PCM sound wailing/crashing in FFmpeg media backend

[Nutchanon Wetchasit]

Follow-up Comment #1, patch #8747 (project gnash):

Patch 2 of 5:
See the attached `0005_dont-skip-resampling-8bit-audio.patch`

Originally, FFmpeg backend ignored non-16 bit audio
<http://git.savannah.gnu.org/cgit/gnash.git/tree/libmedia/ffmpeg/AudioResamplerFfmpeg.cpp?id=516a6cae2301c582b54d7f00188c8e22c5d76c1b#n52>
when checking whether
it needed to call FFmpeg/libAV audio resampler, if user's
FFmpeg/libAV version didn't have both `swresample.h` and `avresample.h`.

This patch makes sure it always consider the possibility that source sample
format is not 16-bit (which is the case when original sound data is 8-bit
PCM),
and invoke the resampler accordingly.
