Re: High definition video capture using PiCapture HD1

The -pts option is really what you want again. Thanks for pointing me to this - it is a big help to understand what is happening in the encoder. I ran some experiments, and you are correct that at 1080p 60fps the SoC is dropping some of the frames. The captured video plays seemed faithful to the so...

Re: High definition video capture using PiCapture HD1

Will you be adding support for 1080i? The PiCapture SD1 has RAM for deinterlacing NTSC and PAL sources, but we don't have that on the HD1 - it is designed for progressive video only. We have implemented a mode on the HD1 that works with 1080i by presenting each half-frame to the GPU at 960x540 reso...

Re: High definition video capture using PiCapture HD1

I'm not going to knock your achievement at all (it's really pretty impressive), but 1080P60? Seeing as you appear to be reusing the OV5647 camera modes those are set up to only allow up to 1080P30. Now you can feed data in faster and the SoC will try to handle it - I can't think of anything in the ...

Re: Composite video input using camera interface

Here are a few example captures using our solution: https://lintestsystems.com/sd1-examples 6by9, you are exactly right about how we are doing this. Of course, this is only standard definition video and so the quality of the result is limited by the source. There doesn't seem to be much degradation ...

Re: Composite video input using camera interface

I'll post a demo soon - the recordings I have now were made with copyrighted material using a DVD player and so we need to make some others. Right now we're not thinking of including audio, since there a lots of solutions out there for that and it is a challenging getting everything on a HAT size bo...

Composite video input using camera interface

After much trial and error, we have implemented an adapter that will capture composite video using the standard Raspberry Pi camera interface and software - no drivers or other changes are required. The adapter emulates the OV5647 camera and operates transparently to the RPi, so that Raspivid, Raspi...
