Runs ffmpeg with the supplied args. Blocking until finished.

Returns true if the binary we are using is the true ffmpeg. This is to avoid conflict with avconv (from the libav project), that some symlink to ffmpeg.

Creates a two pass job, which will execute FFmpeg twice to produce a better quality output. More info: https://trac.ffmpeg.org/wiki/x264EncodingGuide#twopass

Convert milliseconds to “hh:mm:ss.ms” String representation.

Converts a string representation of bitrate to a long of bits per second

Returns true if the binary we are using is the true ffprobe. This is to avoid conflict with avprobe (from the libav project), that some symlink to ffprobe.

Add additional ouput arguments (for flags which aren’t currently supported).

Adds new output file.

Adds new output file.

Adds an existing FFmpegOutputBuilder. This is similar to calling the other addOuput methods but instead allows an existing FFmpegOutputBuilder to be used, and reused.

List<String> args = new FFmpegBuilder()
  .addOutput(new FFmpegOutputBuilder()
    .setFilename("output.flv")
    .setVideoCodec("flv")
  )
  .build();

Create new output (to stdout)

Add additional ouput arguments (for flags which aren’t currently supported).

Add metadata on output streams. Which keys are possible depends on the used codec.

Builds the arguments

Returns a representation of this Builder that can be safely serialised. NOTE: This method is horribly out of date, and its use should be rethought.

Checks if the URI is valid for streaming to

Sets the Audio bit rate

Sets the number of audio channels

Sets the audio sample format.

See also: net.bramp.ffmpeg.FFmpeg.AUDIO_FORMAT_U8, net.bramp.ffmpeg.FFmpeg.AUDIO_FORMAT_S16, net.bramp.ffmpeg.FFmpeg.AUDIO_FORMAT_S32, net.bramp.ffmpeg.FFmpeg.AUDIO_FORMAT_FLT, net.bramp.ffmpeg.FFmpeg.AUDIO_FORMAT_DBL

Sets the Audio sample rate, for example 44_000.

Stop writing the output after duration is reached.

Set the number of video frames to record.

When doing multi-pass we add a little extra padding, to ensure we reach our target

Decodes but discards input until the offset.

Target output file size (in bytes)

Sets Video Filter TODO Build a fluent Filter builder

Sets the video’s frame rate

Set the video frame rate in terms of frames per interval. For example 24fps would be 24/1, however NTSC TV at 23.976fps would be 24000 per 1001.

Sets video resolution based on an abbreviation, e.g. “ntsc” for 720x480, or “vga” for 640x480

Match the stream by stream id (e.g. PID in MPEG-TS container).

Matches all streams in the program.

Matches the stream with number stream_index in the program with the id program_id.

Matches the stream with this index.

Matches all streams of this type.

Matches the stream number stream_index of this type.

Matches all streams with the given metadata tag.

Matches streams with the metadata tag key having the specified value.

Matches streams with usable configuration, the codec must be defined and the essential information such as video dimension or audio sample rate must be present.

Waits until a process finishes or a timeout occurs

Demux the inputstream

Read the magic at the beginning of the file.

Read headers we don’t know how to parse yet, returning the next startcode.

Executes when a new frame is found.

Executes when a new stream is found.

Parses a FourCC into a AudioEncoding based on the following rules: “ALAW” = A-LAW “ULAW” = MU-LAW P[type][interleaving][bits] = little-endian PCM [bits][interleaving][type]P = big-endian PCM Where:   [type] is S for signed integer, U for unsigned integer, F for IEEE float   [interleaving] is D for default, P is for planar.   [bits] is 8/16/24/32

Creates a URL to parse to FFmpeg based on the scheme, address and port. TODO Move this method to somewhere better.
