## Data Fields
int | flags
| ORed combination of GAVL_COMPRESSION_* flags.
gavl_codec_id_t | id
| Codec ID.
gavl_buffer_t | codec_header
| Global header.
int | bitrate
| Needed by some codecs, negative values mean VBR.
int | palette_size
| Size of the embedded palette for image codecs.

| Samples to skip at the start.
int | video_buffer_size
| VBV buffer size for video (in BYTES).
uint32_t | codec_tag
int | block_align

## Detailed Description

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.
