Initialize device capabilities submodule. @see avdevice_capabilities_create() for more details.
If extensions are defined, then no probe is done. You should usually not use extension format guessing because it is not reliable enough
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 submodule. @see avdevice_capabilities_free() for more details.
Returns device list with it properties. @see avdevice_list_devices() for more details.
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.
Comma-separated list of mime types. It is used check for matching mime types while probing. @see av_probe_input_format2
A comma separated list of short names for the format. New names may be appended with a minor bump.
No fields below this line are part of the public API. They may not be used outside of libavformat and can be changed and removed at will. New public fields should be added right above. ****************************************************************
< AVClass for the private context
Size of private data so that it can be allocated in the wrapper.
Raw demuxers store their codec ID here.
Close the stream. The AVFormatContext and AVStreams are not freed by this function
Read the format header and initialize the AVFormatContext structure. Return 0 if OK. 'avformat_new_stream' should be called to create new streams.
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). @return 0 on success, < 0 on error. When returning an error, pkt must not have been allocated or must be freed before returning
Pause playing - only meaningful if using a network-based format (RTSP).
Start/resume playing - only meaningful if using a network-based format (RTSP).
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.
Seek to a given timestamp relative to the frames in stream component stream_index. @param stream_index Must not be -1. @param flags Selects which direction should be preferred if no exact match is available. @return >= 0 on success (but not necessarily the new offset)
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.
Get the next timestamp in streamstream_index.time_base units. @return the timestamp or AV_NOPTS_VALUE if an error occurred
