int av_open_input_stream(com.sun.jna.ptr.PointerByReference ic_ptr,
 AVFormatLibrary.ByteIOContext pb,
 String filename,
 AVFormatLibrary.AVInputFormat fmt,
 AVFormatLibrary.AVFormatParameters ap)

Allocates all the structures needed to read an input stream. This does not open the needed codecs for decoding the stream[s].

av_open_input_file

int av_open_input_file(com.sun.jna.ptr.PointerByReference ic_ptr,
 String filename,
 AVFormatLibrary.AVInputFormat fmt,
 int buf_size,
 AVFormatLibrary.AVFormatParameters ap)

Open a media file as input. The codecs are not opened. Only the file header (if present) is read.

Parameters:

ic_ptr - the opened media file handle is put here

filename - filename to open.

fmt - if non NULL, force the file format to use

buf_size - optional buffer size (zero if default is OK)

ap - additional parameters needed when opening the file (NULL if default)

Returns:

0 if OK. AVERROR_xxx otherwise.

av_alloc_format_context

AVFormatLibrary.AVFormatContext av_alloc_format_context()

av_find_stream_info

int av_find_stream_info(AVFormatLibrary.AVFormatContext ic)

av_read_packet

int av_read_packet(AVFormatLibrary.AVFormatContext s,
 AVFormatLibrary.AVPacket pkt)

av_read_frame

int av_read_frame(AVFormatLibrary.AVFormatContext s,
 AVFormatLibrary.AVPacket pkt)

Return the next frame of a stream. The returned packet is valid until the next av_read_frame() or until av_close_input_file() and must be freed with av_free_packet. For video, the packet contains exactly one frame. For audio, it contains an integer number of frames if each frame has a known fixed size (e.g. PCM or ADPCM data). If the audio frames have a variable size (e.g. MPEG audio), then it contains one frame. pkt->pts, pkt->dts and pkt->duration are always set to correct values in AVStream.timebase units (and guessed if the format cannot provided them). pkt->pts can be AV_NOPTS_VALUE if the video format has B frames, so it is better to rely on pkt->dts if you do not decompress the payload.

Returns:

0 if OK, invalid input: '<' 0 if error or end of file.

av_seek_frame

int av_seek_frame(AVFormatLibrary.AVFormatContext s,
 int stream_index,
 long timestamp,
 int flags)

Seek to the key frame at timestamp. 'timestamp' in 'stream_index'.

Parameters:

stream_index - If stream_index is (-1), a default stream is selected, and timestamp is automatically converted from AV_TIME_BASE units to the stream specific time_base.

timestamp - timestamp in AVStream.time_base units or if there is no stream specified then in AV_TIME_BASE units

flags - flags which select direction and seeking mode

Returns:

>= 0 on success

av_read_play

int av_read_play(AVFormatLibrary.AVFormatContext s)

start playing a network based stream (e.g. RTSP stream) at the current position

av_read_pause

int av_read_pause(AVFormatLibrary.AVFormatContext s)

Open a write only packetized memory stream with a maximum packet size of 'max_packet_size'. The stream is stored in a memory buffer with a big endian 4 byte header giving the packet size in bytes.

Parameters:

s - new IO context

max_packet_size - maximum packet size (must be > 0)

Returns:

zero if no error.

pbuffer - to a byte buffer

Returns:

the length of the byte buffer
