Start playing a network-based stream (e.g. More.Īvformat_seek_file ( AVFormatContext * s, int stream_index, int64_t min_ts, int64_t ts, int64_t max_ts, int flags)ĭiscard all internally buffered data. More.Īv_seek_frame ( AVFormatContext * s, int stream_index, int64_t timestamp, int flags) More.Īv_read_frame ( AVFormatContext * s, AVPacket * pkt) More.Īv_program_add_stream_index ( AVFormatContext *ac, int progid, unsigned int idx)Īv_find_best_stream ( AVFormatContext *ic, enum AVMediaType type, int wanted_stream_nb, int related_stream, AVCodec **decoder_ret, int flags)įind the 'best' stream in the file. More.Īv_find_program_from_stream ( AVFormatContext *ic, AVProgram *last, int s)įind the programs which belong to a given stream. Read packets of a media file to get stream information. More.Īvformat_find_stream_info ( AVFormatContext *ic, AVDictionary ** options) Open an input stream and read the header. More.Īvformat_open_input ( AVFormatContext **ps, const char *url, ff_const59 AVInputFormat * fmt, AVDictionary ** options) Like av_probe_input_buffer2() but returns 0 on success. More.Īv_probe_input_buffer ( AVIOContext *pb, ff_const59 AVInputFormat ** fmt, const char *url, void *logctx, unsigned int offset, unsigned int max_probe_size) Probe a bytestream to determine the input format. More.Īv_probe_input_format ( ff_const59 AVProbeData *pd, int is_opened)Īv_probe_input_format2 ( ff_const59 AVProbeData *pd, int is_opened, int *score_max)Īv_probe_input_format3 ( ff_const59 AVProbeData *pd, int is_opened, int *score_ret)Īv_probe_input_buffer2 ( AVIOContext *pb, ff_const59 AVInputFormat ** fmt, const char *url, void *logctx, unsigned int offset, unsigned int max_probe_size)

In the lavf API this process is represented by the avformat_open_input() function for opening a file, av_read_frame() for reading a single packet and finally avformat_close_input(), which does the cleanup.Īv_find_input_format (const char *short_name)įind AVInputFormat based on the short name of the input format. A packet contains one or more encoded frames which belongs to a single elementary stream. Demuxers read a media file and split it into chunks of data ( packets).
