◆ codec_tag
const struct AVCodecTag* const* AVInputFormat::codec_tag |
◆ create_device_capabilities
◆ extensions
const char* AVInputFormat::extensions |
If extensions are defined, then no probe is done. You should usually not use extension format guessing because it is not reliable enough
◆ flags
Can use flags: AVFMT_NOFILE, AVFMT_NEEDNUMBER, AVFMT_SHOW_IDS, AVFMT_GENERIC_INDEX, AVFMT_TS_DISCONT, AVFMT_NOBINSEARCH, AVFMT_NOGENSEARCH, AVFMT_NO_BYTE_SEEK, AVFMT_SEEK_TO_PTS.
◆ free_device_capabilities
◆ get_device_list
◆ long_name
const char* AVInputFormat::long_name |
Descriptive name for the format, meant to be more human-readable than name. You should use the NULL_IF_CONFIG_SMALL() macro to define it.
◆ mime_type
const char* AVInputFormat::mime_type |
Comma-separated list of mime types. It is used check for matching mime types while probing.
- See also
- av_probe_input_format2
◆ name
const char* AVInputFormat::name |
A comma separated list of short names for the format. New names may be appended with a minor bump.
◆ next
◆ priv_class
const AVClass* AVInputFormat::priv_class |
◆ priv_data_size
int AVInputFormat::priv_data_size |
Size of private data so that it can be allocated in the wrapper.
◆ raw_codec_id
int AVInputFormat::raw_codec_id |
Raw demuxers store their codec ID here.
◆ read_close
Close the stream. The AVFormatContext and AVStreams are not freed by this function
◆ read_header
Read the format header and initialize the AVFormatContext structure. Return 0 if OK. 'avformat_new_stream' should be called to create new streams.
◆ read_packet
Read one packet and put it in 'pkt'. pts and flags are also set. 'avformat_new_stream' can be called only if the flag AVFMTCTX_NOHEADER is used and only in the calling thread (not in a background thread).
- Returns
- 0 on success, < 0 on error. When returning an error, pkt must not have been allocated or must be freed before returning
◆ read_pause
Pause playing - only meaningful if using a network-based format (RTSP).
◆ read_play
Start/resume playing - only meaningful if using a network-based format (RTSP).
◆ read_probe
Tell if a given file has a chance of being parsed as this format. The buffer provided is guaranteed to be AVPROBE_PADDING_SIZE bytes big so you do not have to check for that unless you need more.
◆ read_seek
int(* AVInputFormat::read_seek) (struct AVFormatContext *, int stream_index, int64_t timestamp, int flags) |
Seek to a given timestamp relative to the frames in stream component stream_index.
- Parameters
-
stream_index | Must not be -1. |
flags | Selects which direction should be preferred if no exact match is available. |
- Returns
- >= 0 on success (but not necessarily the new offset)
◆ read_seek2
int(* AVInputFormat::read_seek2) (struct AVFormatContext *s, int stream_index, int64_t min_ts, int64_t ts, int64_t max_ts, int flags) |
Seek to timestamp ts. Seeking will be done so that the point from which all active streams can be presented successfully will be closest to ts and within min/max_ts. Active streams are all streams that have AVStream.discard < AVDISCARD_ALL.
◆ read_timestamp
int64_t(* AVInputFormat::read_timestamp) (struct AVFormatContext *s, int stream_index, int64_t *pos, int64_t pos_limit) |
Get the next timestamp in stream[stream_index].time_base units.
- Returns
- the timestamp or AV_NOPTS_VALUE if an error occurred
