- * Decodes a video frame from \p buf into \p picture.
- * The avcodec_decode_video() function decodes a video frame from the input
- * buffer \p buf of size \p buf_size. To decode it, it makes use of the
- * video codec which was coupled with \p avctx using avcodec_open(). The
- * resulting decoded frame is stored in \p picture.
- *
- * @warning The input buffer must be \c FF_INPUT_BUFFER_PADDING_SIZE larger than
- * the actual read bytes because some optimized bitstream readers read 32 or 64
- * bits at once and could read over the end.
- *
- * @warning The end of the input buffer \p buf should be set to 0 to ensure that
- * no overreading happens for damaged MPEG streams.
- *
- * @note You might have to align the input buffer \p buf and output buffer \p
- * samples. The alignment requirements depend on the CPU: on some CPUs it isn't
- * necessary at all, on others it won't work at all if not aligned and on others
- * it will work but it will have an impact on performance. In practice, the
- * bitstream should have 4 byte alignment at minimum and all sample data should
- * be 16 byte aligned unless the CPU doesn't need it (AltiVec and SSE do). If
- * the linesize is not a multiple of 16 then there's no sense in aligning the
- * start of the buffer to 16.
- *

- * @param[in] buf the input buffer

- * Pixel format. Notes:

- * color is put together as:
- * (A << 24) | (R << 16) | (G << 8) | B
- * This is stored as BGRA on little endian CPU architectures and ARGB on

- *
- * When the pixel format is palettized RGB (PIX_FMT_PAL8), the palettized
- * image data is stored in AVFrame.data[0]. The palette is transported in
- * AVFrame.data[1] and, is 1024 bytes long (256 4-byte entries) and is
- * formatted the same as in PIX_FMT_RGB32 described above (i.e., it is
- * also endian-specific). Note also that the individual RGB palette
- * components stored in AVFrame.data[1] should be in the range 0..255.
- * This is important as many custom PAL8 video codecs that were designed
- * to run on the IBM VGA graphics adapter use 6-bit palette components.

-How to download an build ffmpeg for UltraStar Deluxe on Mac OS X:
-
-1. Open a terminal.
-
-2. cd into the Game/Code/lib/ffmpeg/src/MacOSX directory
-
-3. Run the following command:
-
-svn checkout svn://svn.mplayerhq.hu/ffmpeg/trunk ffmpeg
-
-4. The compile ffmpeg. I made a script for this:
-
-./build_ffmpeg.sh
-
-5. On OS X you have to patch the the dylibs. Run the following
- script. It patches the dylibs and copies them to the
- lib/ffmpeg dir:
-
-./copy_and_patch_dylibs.sh
-
-
-You're done.
