#include <compression.h>
Data Fields | |
uint32_t | flags |
ORed combination of GAVL_COMPRESSION_* flags. | |
gavl_codec_id_t | id |
Codec ID. | |
uint8_t * | global_header |
Global header. | |
uint32_t | global_header_len |
Length of global header. | |
int32_t | bitrate |
Needed by some codecs, negative values mean VBR. | |
int | palette_size |
Size of the embedded palette for image codecs. | |
uint32_t | pre_skip |
Samples to skip at the start. | |
uint32_t | video_buffer_size |
VBV buffer size for video (in BYTES). | |
uint32_t | max_packet_size |
Maximum packet size or 0 if unknown. | |
uint32_t | max_ref_frames |
Maximum reference frames (if > 2). |
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 |
Samples to skip at the start.
VBV buffer size for video (in BYTES).
Maximum packet size or 0 if unknown.
Maximum reference frames (if > 2).
