This conformant component accepts audio and video frames and writes
the data to a file with a given file format. The format of the file is
determined by the extension of the given target filename. A stream
cannot be added once the component has moved to the executing
state. The file will be closed when an EOS is received on all enabled
ports or when there are no remaining enabled ports. Once the file is
closed, it may not be re-written, nor another file written, until the
component has been transitioned back to the loaded state.
| Port | Index | Notes
|
| 170 171 | OMX_IndexParamPortDefinition
| Query / set the format of the stream on the input port specified.
|
| OMX_IndexConfigBrcmPortStats
| Query for the port statistics for the given input port. Arriving
buffers are counted, with the number of frames and bytes also counted.
|
| OMX_IndexParamBrcmCRC
| Query for the latest CRC for input data on this port.
|
| OMX_IndexParamCodecConfig
| Sets the codec config structure. When tunneled, this is automatically
queried by the component on the tunnel output port, so only needs to
be set when the port is acting in non-tunneled mode.
|
| OMX_IndexParamBrcmDataUnit
| Sets the type of data delivery for the encoded data
(OMX_DataUnitCodedPicture or
OMX_DataUnitArbitraryStreamSection). By default the component
assumes OMX_DataUnitArbitraryStreamSection, but will also issue
a OMX_IndexParamBrcmDataUnit request when tunnelling the input
port to find out the value it should use. Note that most structured
container formats require fully framed input data.
|
| OMX_IndexParamBrcmDrmEncryption
| Query / set DRM encryption scheme for data written on the input port.
|
| 170 | OMX_IndexParamAudioPortFormat
| Query / set the audio port format. This port supports several audio
formats, and doesn't support any conversion.
|
| OMX_IndexParamAudioMp3
| Query / set the MP3 properties of the audio stream.
|
| OMX_IndexParamAudioAac
| Query / set the AAC properties of the audio stream.
|
| OMX_IndexParamAudioPcm
| Query / set the PCM properties of the audio stream.
|
| OMX_IndexParamAudioWma
| Query / set the WMA properties of the audio stream.
|
| OMX_IndexParamAudioVorbis
| Query / set the Vorbis properties of the audio stream.
|
| OMX_IndexParamAudioAmr
| Query / set the AMR properties of the audio stream.
|
| 171 | OMX_IndexParamVideoPortFormat
| Query / set the video port format. This port supports several video
formats, and doesn't support any conversion.
|
| OMX_IndexConfigBrcmOutputBufferFullCount
| Query the number of times the output buffer has filled up. This is a rough guide to
whether or not the output destination (SD card typically) is keeping up. This
configuration value can be monitored via OMX_IndexConfigRequestCallback.
|
| OMX_IndexConfigRequestCallback
| Set whether we enable a callback to the client when the value of this
index structure changes. Only supported for the
index OMX_IndexConfigBrcmOutputBufferFullCount.
|
| OMX_IndexParamVideoAvc
| Query / set the H264 properties of the audio stream.
|
| OMX_IndexParamVideoH263
| Query / set the H263 properties of the audio stream.
|
| OMX_IndexParamVideoMpeg4
| Query / set the MPEG4 properties of the audio stream.
|
| | OMX_IndexParamContentURI
| Query / set the target filename. Currently the format of the URI is
assumed to be a file that the component can directly access using the
file system.
|
| OMX_IndexParamBrcmOutputBufferSize
| Query / set the output buffering size in bytes. This is a hint to the underlying handler,
and may be ignored.
|
| OMX_IndexParamBrcmMaxFileSize
| Limit the maximum file size that can be generated. An error will be reported when
this size is reached.
|
| OMX_IndexParamBrcmCRCEnable
| Query / set whether this component should calculate CRCs on all input
data received. Setting this index resets CRCs on all ports to zero.
CRC calculation defaults to off.
|
| OMX_IndexConfigBrcmIOPerfStats
| Query for statistics about I/O (e.g. file media) performance. Set whether or not
this component captures these statistics (off by default) by changing the
bEnabled field. Other fields are read-only and will be ignored upon set.
