Interface Muxer

  • All Known Implementing Classes:DefaultMuxer, InAppMuxer
[@Deprecated](https://developer.android.com/reference/java/lang/Deprecated.html "class or interface in java.lang")public interfaceMuxer

Deprecated. com.google.android.exoplayer2 is deprecated. Please migrate to androidx.media3 (which contains the same ExoPlayer code). See the migration guide for more details, including a script to help with the migration.

Abstracts media muxing operations.

Query whether sample MIME types are supported and add all tracks, then write sample data to mux samples. Once any sample data has been written, it is not possible to add tracks. After writing all sample data, release the instance to finish writing to the output and return any resources to the system.

Method Detail

-

addTrack

int addTrack​([Format](../Format.html "class in com.google.android.exoplayer2")format)
      throws[Muxer.MuxerException](Muxer.MuxerException.html "class in com.google.android.exoplayer2.transformer")

Deprecated.

Adds a track with the specified format. Parameters:format - The Format of the track.Returns:The index for this track, which should be passed to writeSampleData(int, java.nio.ByteBuffer, long, @com.google.android.exoplayer2.C.BufferFlags int).Throws:Muxer.MuxerException - If the muxer encounters a problem while adding the track.

-

writeSampleData

void writeSampleData​(int trackIndex,[ByteBuffer](https://developer.android.com/reference/java/nio/ByteBuffer.html "class or interface in java.nio")data,
                     long presentationTimeUs,
                     @com.google.android.exoplayer2.C.BufferFlags int flags)
              throws[Muxer.MuxerException](Muxer.MuxerException.html "class in com.google.android.exoplayer2.transformer")

Deprecated.

Writes the specified sample. Parameters:trackIndex - The index of the track, previously returned by addTrack(Format).data - A buffer containing the sample data to write to the container.presentationTimeUs - The presentation time of the sample in microseconds.flags - The C.BufferFlags associated with the data. Only C.BUFFER_FLAG_KEY_FRAME and C.BUFFER_FLAG_END_OF_STREAM are supported.Throws:Muxer.MuxerException - If the muxer fails to write the sample.

-

addMetadata

void addMetadata​([Metadata](../metadata/Metadata.html "class in com.google.android.exoplayer2.metadata")metadata)

Deprecated.

Adds Metadata about the output file.

-

release

void release​(boolean forCancellation)
      throws[Muxer.MuxerException](Muxer.MuxerException.html "class in com.google.android.exoplayer2.transformer")

Deprecated.

Finishes writing the output and releases any resources associated with muxing.

The muxer cannot be used anymore once this method has been called.

Parameters:forCancellation - Whether the reason for releasing the resources is the export cancellation.Throws:Muxer.MuxerException - If the muxer fails to finish writing the output and forCancellation is false.

-

getMaxDelayBetweenSamplesMs

long getMaxDelayBetweenSamplesMs()

Deprecated.

Returns the maximum delay allowed between output samples, in milliseconds, or C.TIME_UNSET if there is no maximum.

This is the maximum delay between samples of any track. They can be of the same or of different track types.

This value is used to abort the export when the maximum delay is reached. Note that there is no guarantee that the export will be aborted exactly at that time.
