Codec Engine 2.25.05.16 Release Notes

June 2010

This Codec Engine Release is targetted to DaVinci and OMAP platforms, enabling users to instantiate and utilize both local and remote codecs. In addition to heterogenous devices (e.g. DM644x, DM6467, OMAP2530, OMAP3530, etc.), it supports single processor environments as well; specifically C64+ devices (e.g. DM643x, and DM648), ARM devices (e.g. DM355, DM365, OMAP3503) and x86 devices running Linux.

Introduction

The Codec Engine is a software platform for algorithm execution that satisfies the following, high-level goals:

• Robust - drives pre-integrated components with fully characterized performance.
• Easy to use - app developers specify what needs to be run, but not how or where.
• Extensible and Configurable - new algorithms can be added by anyone, using standard tools and techniques.
• Portable - API's are target, platform, and in many cases even codec independant.

Primary packages in this Codec Engine release are briefly described here. (There are others, see the Configuration Reference Guide documentation for a complete package list.)

• ti.sdo.ce - The Codec Engine runtime.
• ti.sdo.ce.video2 - The Codec Engine video component (supporting the XDM IVIDDEC2 interface). An example is also provided.
• ti.sdo.ce.video1 - The Codec Engine video component (supporting the XDM IVIDDEC1 and IVIDENC1 interfaces). An example is also provided.
• ti.sdo.ce.image1 - The Codec Engine image component (supporting the XDM IIMGDEC1 and IIMGENC1 interfaces). An example is also provided.
• ti.sdo.ce.speech1 - The Codec Engine speech component (supporting the XDM ISPHDEC1 and ISPHENC1 interfaces). An example is also provided.
• ti.sdo.ce.audio1 - The Codec Engine audio component (supporting the XDM IAUDDEC1 and IAUDENC1 interfaces). An example is also provided.
• ti.sdo.ce.osal - The Codec Engine OS Abstraction Layer. This package insulates CE from the OS it's running on, and provides a few Modules for customers to use (e.g. Memory).
• ti.sdo.ce.utils.trace - The Codec Engine utility package for trace. This includes the TraceUtils module. This makes tracing features easier to use by an application. It will be supported in this release, but may be replaced in a future release with an incompatible implementation.

Additionally, this release of the Codec Engine continues to support the deprecated XDM interfaces included in XDAIS 5.00. This support is provided in the following packages:

• ti.sdo.ce.video - The Codec Engine video component (supporting the XDM IVIDDEC and IVIDENC interfaces). An example is also provided.
• ti.sdo.ce.image - The Codec Engine image component (supporting the XDM IIMGDEC and IIMGENC interfaces). An example is also provided.
• ti.sdo.ce.speech - The Codec Engine speech/voice component (supporting the XDM ISPHDEC and ISPHENC interfaces). An example is also provided.
• ti.sdo.ce.audio - The Codec Engine audio component (supporting the XDM IAUDDEC and IAUDENC interfaces). An example is also provided.

Codec Engine is provided as non-rebuildable libraries. Source is provided for debugging and educational value, but is not intended to be modified. Modified sources will not be supported.

Some distributions of this product include a "cetools" directory containing some dependent products for convenience. Products included in this release are:

2.10

• New features
  • Updated C6x libraries to CG Tools 6.0.16
  • Added support for DM6467
  • Added support for IVIDDEC2 interface.
  • Added "experimental" asynchronous API support. Some customers have requested support for asynchronous VISA APIs. This release provides that support - with "experimental" quality. That is, the APIs are supported, but compatibility in future releases may be broken or removed/replaced completely. Customers should feel free to use these APIs in products, but look for further guidance and roadmap advice from TI as the product lifecycle continues.
• Updated Dependencies
  • XDAIS 6.10
  • Framework Components 2.10
    • For codecs that acquire EDMA3 channels via IRES, FC release notes state the appropriate, dependent EDMA3 LLD product version.

  SDSCM00023298	VIDDEC1 doesn't provide enough buffers for CIF decode (17 needed)

• The following enhancements were resolved:

  ID

  Headline

2.00

• New features
  • In Linux-based applications, Codec Engine is now callable from multiple processes. For environments that require DSP/BIOS Link (e.g. DM644x), users must use Link 1.40.05 P3. For single processor environments (e.g. DM355), no special instructions are required. Note that, as always, codecs that share resources must be configured into the same scratch group. These scratch groups span processes - so if two different apps use codecs that share resources, the system integrator must ensure they are placed into the same system-wide scratch group.
  • Support for the new IVIDTRANSCODE XDM API has been added. This provides a standard API for invoking video transcoding algorithms. See the Reference Guide for details.
  • Added cache management configuration to XDM 0.9-based remote image and video algorithms. Using this feature, it is possible to configure these interfaces to not writeback the output data buffers if, for example, these are being moved between internal and external (shared) memory using DMA. This can significantly improve performance of remote process() calls, as writing back large video or image buffers is time consuming. See the Configuration Reference Guide, specifically the ti.sdo.ce.video.VIDDECConfig/.VIDENCConfig (and similar modules in the ti.sdo.ce.image package) for details.
  • Applications can create remote instances of the same algorithm to run at different priorities. This enables applications to have, for example, background transcoding or encoding tasks running alongside real-time encode or decode operations that use the same codec. This is handled by adding the priority to the codec name during creation (e.g. "mpeg3dec:4"). See the Application Developer's Guide and API Reference Guide for details.
  • Improved trace usability with new CE_DEBUG environment variable. See the Application Developer's Guide for details.
• Updated Dependencies
  • Updated to XDAIS 6.00
  • Updated to Framework Components 2.00
  • Updated to CMEM 2.00
  • Updated to XDC 3.00.01
• The following defects were resolved:

  ID	Headline
  SDSCM00017691	viddec1_skel.c has wrong array index
  SDSCM00019236	SPHDEC1 and SPHENC1 stubs/skels don't support inArgs->data and outBuf->bufSize fields
  SDSCM00019266	VISA _create() calls with params.size "too big" cause assert for remote algs
  SDSCM00019432	XDM 1.00 stubs fail to initialize internal status->data.buf to NULL
  SDSCM00019767	Need to provide workaround for ISPHENC1/ISPHDEC1 creation params

• The following enhancements were resolved:

  ID	Headline
  SDSCM00010976	Provide per-codec instance priority configuration/modification
  SDSCM00015261	Codec Engine must be callable from multiple Linux Processes
  SDSCM00017409	Provide an example app demonstrating dynamically loading a CE .so
  SDSCM00018299	Add support for 'registering/unregistering' non-CMEM managed buffers in the Memory_ lookup tables

1.20

• General
  • Updated to XDAIS 5.21, which includes XDM 1.00 interfaces
  • Updated to DSP/BIOS Link 1.40.05 - this resulted in some necessary configuration-related changes
  • Updated to Framework Components 1.20.02
  • Updated to new XDC Tools 2.93.01
  • Updated to CMEM 1.04
  • Added examples for single-processor, environments (e.g. DM643x) - this includes placing executables into platform-specific directories, as well as demonstrating necessary caching techniques for cache-enabled environments.
  • Added Link Arbiter Daemon (LAD)
  • Added CERuntime_exit() for applications which want to erase any CE Runtime from their environment without exiting their application. This is useful if, for example, an application wants to switch between a Codec Engine based environment, and a custom DSP Link-based framework.
  • Moved examples into "Codec Engine-specific" namespaces (e.g., the previous codecs.viddec1_copy codec package is now the ti.sdo.ce.examples.codecs.viddec1_copy package).
  • Added configuration option to XDM 0.9-based video encoders to not manage the cache for the reconstruction buffers.
  • Added 'checked' builds to the distribution. This enables some parameter and usage validation to occur within the CE framework, helping to identify common coding errors in both applications and algorithms. Enabling this optional feature introduces some performance overhead, but is encouraged for those early in development. This can be enabled in the application configuration, as well as the Server (for systems with remote algorithms). See the documentation on the ti.sdo.ce.Settings Module's "checked" parameter in the Configuration Reference Guide.
• BIOS-based environments
  • Added LOG_events for profiling performance
• The following defects were resolved:

  ID	Headline
  SDSCM00014413	xdcpaths.mak requires FC installation in ".lite" release
  SDSCM00014540	CE OSAL requires presence of dsplink.dsp package even if it's used in a DSP/BIOS-only setting
  SDSCM00015336	Scale example's SCALE_Params struct does not have the required IALG_Params struct as its first element

• The following enhancements were resolved:

  ID	Headline
  SDSCM00013759	CMEM should support multiple processes
  SDSCM00014703	Add Memory_cacheWb() to OSAL

1.10

• General
  • Updated to C6x Codegen 6.0.7
  • Updated to DSP/BIOS 5.31.01
  • Updated to Framework Components 1.10.01
  • Updated to XDAIS 5.10, which includes XDM 1.00 beta interfaces
• CE Runtime
  • Added new methods to ti.sdo.ce.ICodec interface (getCreationStackSize(), getDaramScratchSize(), and getSaramScratchSize()) to make Server configuration easier. When codecs implement these methods, the XDC Tools are able to either:
    1. Auto-generate the DSKT2 scratch configuration, or
    2. Validate the scratch config (if the server integrator wants to continue explicitly configuring those values).
• VISA
  • Added support for XDM 1.00 Beta interfaces. (Previous XDM 0.9 interfaces continue to be supported)
• SPI (System Programming Interfaces)
  • Added VISA_setContext() and VISA_getContext() services for stub/skeleton/API authors.
• Documentation
  • Added "Adapter" application note describing how to integrate non-XDM codecs, as well as a technique for adding pre- and post- processing steps to existing codecs without modifying them.
• Examples
  • Added new, Linux-only example demonstrating how users can create a shared library from a single configuration, which can then be used by multiple applications.
  • Added a new example, explicitly describing the steps taking during configuration to better demonstrate the necessary configuration steps for users who want to integrate this into their own, custom build flows.
  • Modified example codecs, when possible, to utilize copy codecs now distributed in XDAIS 5.10. In this way, it's more clearly described what little XDC packaging is required to integrate an already XDC packaged Codec (independant of CE) into the CE framework.
• Defects
  • SDSCM00010422 - CE and CMEM should set the close-on-exec flag on any open file handles
  • SDSCM00005810 - Additional C++ testing required
  • SDSCM00004993 - GT no longer supports wildcards as second character
  • SDSCM00004805 - GT computes (a lot) during GT_?trace()
• Enhancements
  • SDSCM00010364 - GT needs productized
  • SDSCM00008121 - not possible to properly size RMS thread's stack
  • SDSCM00007887 - Support VISA_getContext/setContext SPIs
  • SDSCM00006616 - CE should ensure unique UUIDs
  • SDSCM00003992 - Add pre- and/or post- process example to codecs
  • SDSCM00002920 - ICodec should have a getScratchSize method

1.02

  • Introduced ti.sdo.ce.utils.trace.TraceUtils module.
  • Libraries are now provided in release builds. Previously, they were debug-only.
  • Introduced Engine_setTrace() API.
  • Added support for C++
• VISA Classes
  • Added extended XDM support to the remaining 3 classes (AUDENC, VIDENC, and SPHENC).
• Documentation
  • Addition of System Programming Interface (SPI) Reference Guide.
  • Codec Engine Server Integrator's Guide (SPRUED5)
  • Codec Engine Algorithm Creator User's Guide (SPRUED6)
  • Minor updates to the Codec Engine Application Developer's Guide (SPRUE67A)

• General
  • Many trace strings were modified/added.
  • C64P libraries built with 6.0.3 compiler.
• VISA Classes
  • Audio Encoding support has been added
  • Better compliance checking of "size" field. This field must be set correctly in the various VISA APIs, as it is now used to determine how much data to provide to the codecs.
  • Related to previous bullet, added extended XDM support to VIDDEC, VIDENC, AUDDEC, IMGDEC, and SPHDEC classes. There are limits to the size of the extended structures, and they must not contain pointers in the extended structures.
  • outArgs fixed to be provided in the case of a failed process() call (enabling inspection of extendedError).
  • Removed cache alignment validation of input buffers. When the application can ensure cache coherence, these buffers need not be aligned.
• Documentation
  • Minor updates to the Codec Engine Application Developer's Guide (SPRUE67A)

Upgrade Information

The Codec Engine packages are available in the "packages/" subdirectory of the product. If you have a previous release of the Codec Engine product, you can install this release next to it, and modify your application and/or server builds to use this newer release.

If you're using the DVEVM, this can be done by setting the CE_INSTALL_DIR variable in the Rules.make file at the top of the DVEVM distribution directory.

Compatibility Breaks!

• CE 2.25.05.16 requires system integrators to update to XDC Tools 3.16.00.18 (or newer).
• CE 2.25.05.16 requires Linux and WinCE system integrators update to DSP Link 1.64 (or compatible).
• CE 2.25.05.16 requires system integrators update to Framework Components 2.25.02.06 (or compatible).
• CE 2.25.05.16 requires system integrators update to XDAIS 6.25.02.11 (or compatible).
• CE 2.25.05.16 requires system integrators update to EDMA3 Resource Manager 01.11.00.02 (or compatible).
• CE 2.25.05.16 requires system integrators update to DSP/BIOS 5.41.00.06 (or compatible).

In order to address SDOCM00062629 (ICodec.serverFxns and .stubFxns shouldn't be 'readonly' so app and server cfg scripts can assign them), the ti.sdo.ce.ICodec interface changed 2 fields (.serverFxns and .stubFxns), removing the 'readonly' attribute so they can be overridden at config time by a .cfg script. The result is that any Modules that implement ICodec (e.g. if you've implemented your own ICodec-derived interface with your own stubs/skels), you need to remove the 'readonly' attribute from your <Module>.xdc file and rebuild your Module. Most users, including those that are simply using the standard VISA interfaces, will not have to do this.

Note, if you're upgrading from a release earlier than Codec Engine 2.24, be sure to review the Upgrade section for each of the releases between your current Codec Engine release and this one. Previous release notes are available in the relnotes_archive directory.

Compatibility Key Definitions

Compatibility keys are intentionally independent of Marketing product numbers and are intended to:

1. Enable tooling to identify incompatibilities between components, and
2. Convey a level of compatibility between different releases to set end user expectations.

Compatibility keys are composed of 3 comma-delimited numbers - M,S,R - where:

• M = Major. A difference in M indicates a break in compatibility.
• S = Source. A difference in S indicates source compability. That is, the user's source doesn't require change, but does require rebuilding.
• R = Radix. A difference in R indicates an introduction of new features, but compatibility with previous interfaces has not broken. If libraries are provided by the package, an application must re-link with the new libraries, but not rebuild from source.

Known Issues

• The IVIDDEC2FRONT VISA interface does not yet support remote algorithms. Until this support is added (and there's currently no plan to!), all IVIDDEC2FRONT algorithms must be local.
• Enabling the capture of remote, BIOS Logs via TraceUtils on any multi-core device other than DM644x is unsupported, and is likely to result in system instabilities. This issue has to do with ti/sdo/ce/bioslog/LogClient.c mapping and reading from a DM644x-specific memory location to perform time synchronization between the cores. Non-DM644x users are recommended to simply not use TraceUtils. Or if they do, to configure out the capture of remote BIOS Logs. More information will be made available at the Known Issues wiki article mentioned below.

See the Codec Engine Known Issues wiki article for issues found after these release notes were compiled.
