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

[Nutchanon Wetchasit]

Follow-up Comment #2, patch #8747 (project gnash):

Patch 3 of 5:
See the attached `0006_use-correct-8bit-pcm-ffmpeg-codec.patch`

Originally, FFmpeg backend mistakenly used a _signed_ 8-bit PCM codec ID
<http://git.savannah.gnu.org/cgit/gnash.git/tree/libmedia/ffmpeg/AudioDecoderFfmpeg.cpp?id=516a6cae2301c582b54d7f00188c8e22c5d76c1b#n186>
when decoding Flash's 8-bit PCM `UNCOMPRESSED`/`RAW` sound, which is actually
an _unsigned_ 8-bit PCM <https://savannah.gnu.org/bugs/?45722#comment26>
data.

This patch corrects it by using an unsigned PCM 8-bit codec ID
(`AV_CODEC_ID_PCM_U8`) instead.
