Compression format.
This defines parameters of the compression. The most important value is the gavl_codec_id_t. Formats, which support a global header, store it here as well.
Usually there must be an associated audio or video format, because some containers need this as well.
| uint32_t gavl_compression_info_t::flags |
ORed combination of GAVL_COMPRESSION_* flags.
Codec ID.
Global header.
Length of global header.
| int32_t gavl_compression_info_t::bitrate |
Needed by some codecs, negative values mean VBR.
Size of the embedded palette for image codecs.
| uint32_t gavl_compression_info_t::pre_skip |
