Deinterlacing in DM368 based on Hardware Accelerator

Other Parts Discussed in Thread: OMAP3530, DM3730

Hello Sir,

We have DM368 based custom board. We are facing problem of deinterlacing in video recording. According to our understanding two methods are available to resolve the deinterlacing problem.

1. By using interlaced encoding.
    We followed the following links to set the Input video types as Interlaced in H.264 encoder configuration. At this link, output storage mechanism was         not described. So we would like to know, how output video stored in memory?

2. Another solution is by using deinterlacing algorithm. For DM368, DVSDK 04_02_00_06 is the latest release of DVSDK. In this DVSDK, deinterlacing algorithm support is not available. We gone through the forums and found that TI provides hardware accelerated based De-Interlacing algorithms with DVSDK. We download the latest release(04_03_00_06) of dvsdk for DM3730 because for DM368 it is not available. In DVSDK 4_03_00_06 Deinterlacer support is available for OMAP3530. We would like to know is it feasible to use the provided deinterlacing algorihtm with DM368? If yes, then how we can use this deinterlacing algorithm for DM368?

Thanks & Regards

  • Hi,

    For Solution #2, the OMAP3530 device has a DSP core. If the deinterlacing algorithm runs on the DSP, it will not be able to run it on DM365 which does not include a DSP core.

    The DM365 H264 Encoder supports interlaced encoding.

    Did you try to configure the encoder to support this feature?

    thanks
