Error From Openmax Component

In practice, the state transitions will only occur for a component when conditions are exactly right for that component. This is the component handle returned by the call to the OMX_GetHandle function. [out]pStatepointer to the location to receive the state.

It's in Loaded State and I want it to pass in Iddle State. Each structure shall be sent one at a time, each in a separate invocation of the macro. pls help me how to solve this problem, how to configure libomxil-bellagio for cross compile best regards daisy Re: [Omxil-devel] Transition from Loaded to Iddle State From: Giulio URLINI - I send the command to pass in Iddle State (OMX_SendCommand) and I allocate my input and output buffers.

Error From Openmax Component

This is a non-blocking call in that the component will record the buffer and return immediately and then empty the buffer, later, at the proper time.

The component should return from this call within 5 msec. @param [in] hComponent Handle of the component to be accessed.

Referenced by audiodecEventHandler(), main(), parser3gpEventHandler(), and videodecEventHandler(). #define OMX_SetConfig ( hComponent, nConfigIndex, pComponentConfigStructure ) Value:((OMX_COMPONENTTYPE*)hComponent)->SetConfig( \ hComponent, \ nConfigIndex, \ pComponentConfigStructure) The OMX_SetConfig macro will send one of the configuration structures The core should return from this call within 20 msec. @return OMX_ERRORTYPE If the command successfully executes, the return code will be OMX_ErrorNone.

If the component receives the pause command while in the * Idle state, the component shall send all input buffers it holds to the * application, but shall not begin processing The TGA format is specified here. This is the component handle returned by the call to the GetHandle function. [in]cParameterNameOMX_STRING that shall be less than 128 characters long including the trailing null byte. click here now I use semaphore locked just after the SendCommand call and unlocked in the callback.

If variable $HOME is not set, the application tries to write the file in the root directory. Each structure shall be sent one at a time, in a separate invocation of the macro. This is a blocking call. And lots of that is staring at the screen in complete bewilderment as to why it isn't working, with no error messages or anything to tell me what is going on

Error From Openmax Component Using the GPU is not well documented. Then, in the doc "OpenMax Call Sequences", it's said "Waits for the EventHandler callback to arrive from the component which notifies the framework that the component state transition is complete (OMX_EventCmdComplete)".

Ports represent both the connection for components to the data stream and the buffers needed to maintain the connection. i downloaded the latest version >> libomxil-bellagio-,and then ./configure ,make,make install >> accroding to README . Component Individual blocks of functionality, including "sources, sinks, codecs, filters, splitters, mixers, or any other data operator." Types of components: Source: component with single output port Sink: component with single input It has to establish the format that it will accept from the input file by // set input image format OMX_IMAGE_PARAM_PORTFORMATTYPE imagePortFormat; memset(&imagePortFormat, 0, sizeof(OMX_IMAGE_PARAM_PORTFORMATTYPE)); imagePortFormat.nSize = sizeof(OMX_IMAGE_PARAM_PORTFORMATTYPE); imagePortFormat.nVersion.nVersion = OMX_VERSION;

  • This is the component handle returned by the call to the GetHandle function. @param pAppData pointer to an application defined value that was provided in the pAppData parameter to the OMX_GetHandle
  • Note that the memory location used for this buffer is NOT visible to the IL Client. @param [in] nPortIndex nPortIndex is used to select the port on the component the buffer
  • nParam1 contains the index of the port on which the buffer mark is applied.

enum OMX_PORTDOMAINTYPE OMX_Component.h - OpenMax IL version 1.1.1 The OMX_Component header file contains the definitions used to define the public interface of a component.

Otherwise the appropriate OMX error will be returned. @ingroup core */OMX_API OMX_ERRORTYPE OMX_APIENTRY OMX_Init(void);/** The OMX_Deinit method is used to deinitialize the OMX core.

A typical component creation will look like ilclient_create_component(decoder->client, &decoder->imageDecoder->component, "image_decode", ILCLIENT_DISABLE_ALL_PORTS | ILCLIENT_ENABLE_INPUT_BUFFERS | ILCLIENT_ENABLE_OUTPUT_BUFFERS) Decoding a JPEG image OpenMAX on the RPi has a standard component OMX.broadcom.image_decode. A major one is ILCLIENT_DISABLE_ALL_PORTS which - as might be expected - disables all ports of the component, to make it easier to transition to idle state later. The application shall allocate the correct structure and shall fill in the structure size and version information before invoking this macro.

We need to set up the input port for the decoder as in the last example.

The component should return from this call within 5 msec. @param [in] hComponent Handle of the component to be accessed. To ensure the array is sufficiently sized the client should: * first call this function with the compNames field NULL to determine the number of component names * second call this This is a blocking call. If you want RGB, you have to do it yourself or use another Broadcom component, the resize component.

The nParamIndex parameter is used to indicate which structure is being requested from the component. Also this is the handle of the component whose port, specified in the nPortOutput parameter will be used the source for the tunnel. When I use the parameter nBufferCountMin of the parameter OMX_PARAM_PORTDEFINITIONTYPE, the transition fails. > > Regards > > > > Kevin > > > > > > > >> Message du Thanks for the details Cheers, Giulio On 05/18/2010 05:11 PM, [email protected]

Definition at line 859 of file OMX_Core.h. The callback function is provided by the application. If the component has not had any settings changed, then the component should return a set of valid DEFAULT parameters for the component. You can't allocate buffers for it until a call has been made to enable it.

This is the component handle returned by the call to the OMX_GetHandle function. @param [in] nIndex Index of the structure to be sent. Please don't fill out this field.

Being exactly right means that all of the resources such as buffers have to be allocated and configured correctly, which is often not so easy. If the component reference count goes to zero, the component will be unloaded from memory. hello_video OMX API calls Here is a sequence of all the OMX API calls that the hello_video sample program makes (from raspberry pi raspbian sample image).

A component's determination of when an output port should * cease sending data is implemenation specific. * @ingroup buf */#define OMX_BUFFERFLAG_EOS 0x00000001 /** Start Time Buffer Flag: * * The source Returns:OMX_ERRORTYPE If the command successfully executes, the return code will be OMX_NoError. When you have assigned your allocated buffers with UseBuffer to any port or requested the component to allocate itself the buffers with the AllocateBuffer call the callback EventHandler is executed to Accesses component's methods.

I'm not sure to have tested this behavior. The component should return from this call within 5 msec. @param [in] hComponent Handle of the component to be accessed. This is the string that will get translated by the component into a configuration index. @param [out] pIndexType a pointer to a OMX_INDEXTYPE to receive the index value. @return OMX_ERRORTYPE If When Cmd has the value "OMX_CommandMarkBuffer" the components pot is given by the value of nParam.
