- (*
- * IMPORTANT: The official FFmpeg C headers change very quickly. Often some
- * of the data structures are changed so that they become incompatible with
- * older header files. The Pascal headers have to be adjusted to those changes,
- * otherwise the application might crash randomly or strange bugs (not
- * necessarily related to video or audio due to buffer overflows etc.) might
- * occur.
- *
- * In the past users reported problems with USDX that took hours to fix and
- * the problem was an unsupported version of FFmpeg. So we decided to disable
- * support for future versions of FFmpeg until the headers are revised by us
- * for that version as they otherwise most probably will break USDX.
- *
- * If the headers do not yet support your FFmpeg version you may want to
- * adjust the max. version numbers manually but please note: it may work but
- * in many cases it does not. The USDX team does NOT PROVIDE ANY SUPPORT
- * for the game if the MAX. VERSION WAS CHANGED.
- *
- * The only safe way to support new versions of FFmpeg is to add the changes
- * of the FFmpeg git repository C headers to the Pascal headers.
- * You can accelerate this process by posting a patch with the git changes
- * translated to Pascal to our bug tracker (please join our IRC chat before
- * you start working on it). Simply adjusting the max. versions is NOT a valid
- * fix.

- * IMPORTANT: The official FFmpeg C headers change very quickly. Often some
- * of the data structures are changed so that they become incompatible with
- * older header files. The Pascal headers have to be adjusted to those changes,
- * otherwise the application might crash randomly or strange bugs (not
- * necessarily related to video or audio due to buffer overflows etc.) might
- * occur.
- *
- * In the past users reported problems with USDX that took hours to fix and
- * the problem was an unsupported version of FFmpeg. So we decided to disable
- * support for future versions of FFmpeg until the headers are revised by us
- * for that version as they otherwise most probably will break USDX.
- *
- * If the headers do not yet support your FFmpeg version you may want to
- * adjust the max. version numbers manually but please note: it may work but
- * in many cases it does not. The USDX team does NOT PROVIDE ANY SUPPORT
- * for the game if the MAX. VERSION WAS CHANGED.
- *
- * The only safe way to support new versions of FFmpeg is to add the changes
- * of the FFmpeg git repository C headers to the Pascal headers.
- * You can accelerate this process by posting a patch with the git changes
- * translated to Pascal to our bug tracker (please join our IRC chat before
- * you start working on it). Simply adjusting the max. versions is NOT a valid

- * Public Metadata API.
- * The metadata API allows libavformat to export metadata tags to a client
- * application using a sequence of key/value pairs. Like all strings in FFmpeg,
- * metadata must be stored as UTF-8 encoded Unicode. Note that metadata
- * exported by demuxers isn't checked to be valid UTF-8 in most cases.
- * Important concepts to keep in mind:
- * 1. Keys are unique; there can never be 2 tags with the same key. This is
- * also meant semantically, i.e., a demuxer should not knowingly produce
- * several keys that are literally different but semantically identical.
- * E.g., key=Author5, key=Author6. In this example, all authors must be
- * placed in the same tag.
- * 2. Metadata is flat, not hierarchical; there are no subtags. If you
- * want to store, e.g., the email address of the child of producer Alice
- * and actor Bob, that could have key=alice_and_bobs_childs_email_address.
- * 3. A tag whose value is localized for a particular language is appended
- * with a dash character ('-') and the ISO 639-2/B 3-letter language code.
- * For example: Author-ger=Michael, Author-eng=Mike
- * The original/default language is in the unqualified "Author" tag.
- * A demuxer should set a default if it sets any translated tag.

- * IMPORTANT: The official FFmpeg C headers change very quickly. Often some
- * of the data structures are changed so that they become incompatible with
- * older header files. The Pascal headers have to be adjusted to those changes,
- * otherwise the application might crash randomly or strange bugs (not
- * necessarily related to video or audio due to buffer overflows etc.) might
- * occur.
- *
- * In the past users reported problems with USDX that took hours to fix and
- * the problem was an unsupported version of FFmpeg. So we decided to disable
- * support for future versions of FFmpeg until the headers are revised by us
- * for that version as they otherwise most probably will break USDX.
- *
- * If the headers do not yet support your FFmpeg version you may want to
- * adjust the max. version numbers manually but please note: it may work but
- * in many cases it does not. The USDX team does NOT PROVIDE ANY SUPPORT
- * for the game if the MAX. VERSION WAS CHANGED.
- *
- * The only safe way to support new versions of FFmpeg is to add the changes
- * of the FFmpeg git repository C headers to the Pascal headers.
- * You can accelerate this process by posting a patch with the git changes
- * translated to Pascal to our bug tracker (please join our IRC chat before
- * you start working on it). Simply adjusting the max. versions is NOT a valid
- * fix.

- * Pixel format. Notes:
- *
- * PIX_FMT_RGB32 is handled in an endian-specific manner. An RGBA
- * 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
- * big-endian CPUs.
- *
- * 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], 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.
- *
- * For all the 8bit per pixel formats, an RGB32 palette is in data[1] like
- * for pal8. This palette is filled in automatically by the function
- * allocating the picture.
- *
- * Note, make sure that all newly added big endian formats have pix_fmt&1==1
- * and that all newly added little endian formats have pix_fmt&1==0
- * this allows simpler detection of big vs little endian.

- * IMPORTANT: The official FFmpeg C headers change very quickly. Often some

- * otherwise the application might crash randomly or strange bugs (not
- * necessarily related to video or audio due to buffer overflows etc.) might
- * occur.
- *
- * In the past users reported problems with USDX that took hours to fix and

- * support for future versions of FFmpeg until the headers are revised by us
- * for that version as they otherwise most probably will break USDX.
- *
- * If the headers do not yet support your FFmpeg version you may want to
- * adjust the max. version numbers manually but please note: it may work but
- * in many cases it does not. The USDX team does NOT PROVIDE ANY SUPPORT
- * for the game if the MAX. VERSION WAS CHANGED.
- *
- * The only safe way to support new versions of FFmpeg is to add the changes
- * of the FFmpeg git repository C headers to the Pascal headers.
- * You can accelerate this process by posting a patch with the git changes
- * translated to Pascal to our bug tracker (please join our IRC chat before
