DLP2021LEQ1EVM: DLP2021LEQ1EVM

Part Number: DLP2021LEQ1EVM

Tool/software:

I’m using the DLP2021LEQ1EVM along with DLP Composer for converting images and videos to bitplanes. While the image conversion is quick, I’ve noticed that video processing (around 7 seconds) takes about 20-30 seconds.

Could you let me know if DLP Composer supports GPU acceleration for faster video-to-bitplane conversions? If so, I’d appreciate any details on supported GPUs or how to enable this feature.

Thank you for your assistance!

  • Hi Hariom,

    I will get in touch with one of our team members to see where we are on this and if it is possible. We will get back to you soon!

  • Hi Hariom,

    DLP Composer does not support GPU acceleration for video conversion. Disabling the compression should decrease the conversion time, but will result in a larger binary. I'll propose this feature to the DLP Composer team, but I suspect this feature will be considered low-priority since the conversion time isn't normally too critical for our customers. Do you have a specific use-case that would require decreasing this conversion time?

    Thanks,

    Andrew

  • Hi Andrew,

    Thank you for the information. The use case we’re considering requires faster processing for real-time applications where generating the image and uploading it in minimal time is a key performance metric. GPU acceleration could significantly reduce delays in this scenario. Disabling compression for faster conversion might work temporarily, but the larger file sizes could be a concern. If this feature can be prioritized, it would greatly benefit our evaluation process.

  • Hi Hariom,

    I'm going to experiment with multi-threading the video to BMP conversion to speed this up. Alternatively I may try using FFMPEG, though I'm not sure we'll see any performance improvement using that instead of multi-threading the current implementation. I'll report back soon with my findings.

    Thanks,

    Andrew

  • A new tool is being developed to speed up the conversion process. This thread will be updated if/when the software is released.
