Important Note: install XDCTOOLS and TI CodeGen tools in directories that don’t have any spaces in their path name (default installation path for these tools may have spaces). Some of the DVSDK component builds fail if there are spaces in the installation path of these tools.

Installation and Usage

Please follow the Getting Started Guide for detailed installation and usage instructions.

Upgrade and Compatibility Information

The OMAP3530 DVSDK release is independently installable. No upgrade instructions are available with this release.

Host Support

This release supports installation and development on Windows XP workstations.

Dependencies

The only known dependencies are listed here.

Device Support

This release supports the Texas Instruments OMAP3530, OMAP3525 and DM3730 SoCs. It was verified on the OMAP3 and DM37x EVMs from Mistral Solutions.

Validation Information

A sanity test of the DVSDK WinCE 100 build 1.11.00.00 was performed before release to the system test team. The sanity test covered the following tests. The validation was done on OMAP35x EVM.

• Play AVI files with MPEG2, MPEG4 and H.264 video decoder and MP3 audio decoder using Windows Media Player. Some of the test clips used for testing and benchmarking can be found here. https://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/media/wince/index_FDS.html
• Run DMAI demonstration applications as described in Getting Started Guide.

In addition, this release has gone through a complete QA cycle.

Exceptions and Known Issues

• The default CMEM configuration does not support the execution of the C6accel_app sample application. Use the CMEM configuration in %DVSDK_INSTALL_DIR%\src\misc\cmem_c6accel.reg instead.
• SDOCM00078531   c6accel verification test failed.    
• SDOCM00078449   DMAI VIDEO DECODER for all codecs is broken on default build but it is working on the 720p special build.    
• SDOCM00078345   The FPS value of H264/MPEG4 decoder output goes down as soon as the graphics demo starts.    
• SDOCM00078341   For 720p, H264 and MPEG4 decoded video's FPS and Rending time becomes wors after rotation.    
• SDOCM00078264   MPEG4 streaming for 720 and D1/CIF is not working.    
• SDOCM00078262   DEV.DVSDK.WINCE.01.11.00.02 which 720p enabled cannot decode D1 and CIF formats h264.    
• SDOCM00078258   Corrupted speech while decoding a clip with properity 720, mpeg4, 30fps, 6Mbps and aac.    
• SDOCM00077780   On DVI output , the screen is Yellowish and the played clips also has yellowish color.    
• SDOCM00076504   Video capture driver - artifacts are seen in output    
• SDOCM00076457   SD card versus RAM - Video encode using capturetest app leads to lower frame rate when writing to SD card    
• SDOCM00076456   Video encode performance using capturetest app on omap3530 is lower than dm3730    
• SDOCM00076326   Playout of MPG file using ceplayer produces corrupted speech.    
• SDOCM00076057   DMAI App - video_decode mpeg4dec app hangs    
• SDOCM00074299   DVSDK 1.10: DirectShow filters for H.264 nd MPEG4 encoders do not support IAMStreamConfig::GetStreamCaps method 
• MP3 playback can only be done on the ARM. This results in higher ARM-side CPU load.
• AV synchronization is sometimes off for H.264 video clips at D1 resolution when the bitrate is high (e.g. >= 2Mbps) on Omap3530 ES2.1 silicon reading the media files from SD card. Performance can be improved by using ES 3.1 silicon with multiple block reads enabled for the SDIO driver.
• WMP cannot be run at the same time as DMAI applications, due to lack of an arbitrator of DSPLINK resources.
• When performing jpeg image encode using DMAI application of an image with dimension (height or width) that is not a multiple of 16, leads to distorted output. This is a JPEG encoder known limitation.
• When performing jpeg image encode using DMAI application, it was observed that using qfactor above 96 leads to misalignment in output image.
• When performing AAC audio decode using DMAI application, high tone heard in decoded file after an aac decode operation.
• When performing AAC audio decode using DMAI application, Mono files are decoded as dualmono during aac decode operations.
• DMAI application does not support 411p and 422i as possible chroma formats
• The default CMEM configuration allows JPEG encode and decode of images with resolutions upto 1280x720 (1MPixel) with YUV444, YUV422, YUV420 formats. Images of higher resolution can be encoded/decoded with appropriate increase in CMEM buffer configuration within limits of available memory
• Rotation may not work for Video codecs that are part of WinCE 6.0 running on ARM (e.g, MPEG1 video, WMV video). These codecs do not handle the stride information properly. Please contact Microsoft for further details.
• SDOCM00057731: MPEG2 Decoder: Flicker is observed at top of the display while decoding Mpeg2 streams of resolution 352x240 with video decode
• SDOCM00062310: MPEG2 Decoder: Generated yuv resolution is not same as the input stream resolution for some MP streams
• SDOCM00060533: MPEG2 Decoder: Unable to decode certain clips @ QCIF resolution
• Digital Video Test Bench is not supported with this release.

Defects Fixed in DVSDK WinCE 1.11.00.03 Patch 01

• Fixed issues related to installation and un-installation of DVSDK setup.exe. The source code and binaries are exactly same as the previous release DVSDK WinCE 1.11.00.02.
1. SDOCM00079755:            (DVSDK_WINCE)Previous version installed with no bump of ver num, uninstall will remove all versions of product
2. SDOCM00079751:            (DVSDK_WINCE) Uninstall of any one (BSP or GFX or DVSDK) will result in uninstalling all three.
3. SDOCM00079549:            DVSDK uninstall script incorrectly removes entire parent directory regardless of whether directory is empty or not

Defects Fixed in DVSDK WinCE 1.11.00.02

Defects Fixed in DVSDK WinCE 1.10.00.00

• MP4 containers are supported for decode in addition to AVI

Defects Fixed in DVSDK WinCE 1.00.00.05

• Updated direct show filters enable Video Rotation using VRFB for Video codecs running on the DSP (H.264 decode, MPEG2 decode, MPEG4 decode).
• Optimization in Multimedia framework, higher DSP clock speed as well as adjustment in display driver buffer settings improves multimedia performance. H.264 video clips at D1 resolution with bitrates of upto 2Mbps can be played without any AV sync issue on ES2.1 silicon with media files on SD card. MPEG2 and MPEG4 video clips at D1 resolution with bitrates upto 4Mbps can be played without AV sync issues. Performance is further improved by using ES 3.1 silicon with multiple block reads enabled for the SDIO driver.

Defects Fixed in DVSDK WinCE 1.00.00.04

• CERuntime_exit() API is called by TI multimedia filter when closing Windows Media Player. This should free up unused resources.
• Benchmarking (--benchmark option) is now supported in DMAI applications
• WMP hangs due to exception in timm.dll when unsupported input file is selected

Defects Fixed in DVSDK WinCE 1.00.00.03

• Reducing the window size of the Windows Media Player to a size smaller than the frame size may result in corrupted output.
• Video display is corrupted when part of the display window lies outside the LCD display.
• Directshow filters do not meet real-time and display is corrupted when video renderer operates in GDI mode (ie. when Windows Media Player is hidden by another window). This is because GDI mode requires YUV to RGB conversion of the DSP codec output frames.
• DMAI Video Encode - for both H.264 and MPEG4 files, error pertaining to contiguous buffer causes failure
• DMAI Image Encode - CMEM configurations to be provided for 1920x1280 and above resolutions
