Gleb Mazovetskiy b7076549a3 osg-ffmpeg-videoplayer: Fix crash on ARM
osg-ffmpeg-videoplayer handled frame allocation incorrectly.

It used a `vector<uint8_t>` as its buffer, meaning the addresses could
did not respect alignment.

Instead, changes it to use `AVFrame` as buffers, allocated via `av_image_alloc`.

We also now only allocate the buffer once, instead of on every frame,
which should improve the framerate of videos.

Fixes the following crash on startup on ARM:

> Invalid address alignment (signal 7)

Fixes #5807
