v0.4.0

Release notes

Features:

• Add integration of the 2A library for the AE/AWB to the GstTIOVXISP element
• Add unit tests for the tiovxdlcolorblend element

Bug Fixes:

• Fix segmentation fault when using tiovxdlcolorblend followed by tiovxmosaic element

Known Limitations:

• By using the IMX219 DCC files in the current PSDK version the element is failing to process images from this sensor. The IMX390 DCC files make the element work with IMX219 captures, but gives incorrect output images.

v0.3.0

Features:

• Add support for ISP plugin
• Add support for LDC plugin
• Handle EOS on MISO pads independently, which allows Mosaic and Colorblend to continue streaming even if one pad has stopped

Bug Fixes:

• Fix copy from a non-TIOVX buffer when stride and width differ on the input image and the destiny vx_image.
  • This affected pipelines that read from filesrc and multifilesrc.
• Fix negotiation with HW decoders

Miscellaneous:

• Add unit tests for:
  • SISO
  • SIMO
  • Colorconvert
  • Mosaic
  • DLPreproc
  • LDC

Known Limitations:

• ISP plugin only supports a single NV12 output
• ISP doesn't perform feedback from the AE WB library

v0.2.3

Features:

• Add background image support to the mosaic

Bug Fixes:

• Fix assertions on multiscaler
• Fix caps leaks on SISO
• Add timestamp information to MISO
• Fixate format on multiscaler src caps

Miscellaneous:

• Use GST_PERFORMANCE logging when copying a buffer

v0.2.2

Bug Fixes

• Fixes an issue where the multiscaler downstream buffer pool allocation sequence caused a memory leak.

v0.2.1

Bug fixes

• Update README with current released GStreamer elements and version.
• Fix issues when releasing allocated memory in the case when multiple GstTIOVX elements are used in the same pipeline.
• Fix memory leak in SIMO class.
• Fix caps renegotiation issues in the tiovxmultiscaler element.

v0.2.0

Features

• Add tiovxdlcolorblend element.
• Add tioxdlpreproc element.
• Add tiovxmosaic element.
• Add MISO base class.
• Add support for PSDK RTOS 8.0.
• Add HotDoc documentation to project repository

Bug fixes

• Fix miscellaneous critical assertions.
• Fix assertions when using multiple consecutive tiovxmultiscaler elements.
• Fix double free issues.
• Fix issues with previous unit tests.
• Fix output buffers not containing timestamp information in the SIMO base class.
• Add support for cases when upstream elements do not query, negotiate or use the buffer pool proposed by GstTIOVX elements.

Known issues

• There are some thin black lines in the output of some frames coming from the tiovxmosaic element.
• There is an issue with the preproc module handling VX_TYPE_INT8 data type. Both the test application. Incorrect results are being generated no matter the format of the input image (NV12/RGB).

v0.1.0

Features:

• Add GstTIOVXSiso class
• Add GstTIVXSimo class
• Add GstTIOVXColorconvert
• Add GsTIOVXMultiscaler
• Add unit tests for Multiscaler and VideoConvert.
• Enabled auto-indexing of code for documentation and updated for all new functions.

Known limitations:

Multiscaler:

• The ROI size custom pad property is not supported, current limitation of TIOVX modules API.

Known issues:

• I420 content is corrupted for some resolutions
