DM365 capture pipeline

Frank Talbot

Other Parts Discussed in Thread: TVP7002

I have been trying for a frustratingly long time to get simple H.264 encoding of a D1 composite capture working on the DM365EVM. I was expecting this to essentially work out of the box, but I'm clearly doing something wrong.

I'm using the Arago 2.6.37 git kernel, linux-davinci branch, updated just a few days ago, with the default configuration for the DM365EVM. It compiles and boots fine.

I'm using TI's H.264 2.30.00.04 production codec. That part works fine; I can encode the sample file.

Originally, I tried to reuse my VPFE capture code that I had for DM6446... which didn't work because that code was compiled against a 2.6.28 kernel that didn't use the Media Controller API. I updated the code to use the MC API, only to find out the encoder only accepts YUV420SP frames, not the UYVY frames from the CCDC capture node that I had been using.

After searching around, it seemed I needed to use the DaVinci Resizer hardware to convert the UYVY frames to the NV12 that the encoder expects. So, I change my device chain to look like this:

tvp514x ---> DAVINCI CCDC ---> DAVINCI PREVIEWER ---> DAVINCI RESIZER ---> DAVINCI VIDEO RSZ output

All of the pads are formatted as 720x480, V4L2_MBUS_FMT_YUYV8_2x8, although I attempted to set the pixel format to V4L2_MBUS_FMT_NV12_1x10 only to have the
driver return V4L2_MBUS_FMT_YUYV8_2x8, anyways. VIDIOC_S_FMT on the resizer output successfully set the format to NV12, though, so I thought it might still work.

Firing up the application, however, saw my capture thread going into the VIDIOC_DQBUF ioctl for the resizer output and never returning...

Digging around, I found the mt9p031_ccdc_prv_rsz_loopback_mmap.c example app in the PSP. Not exactly the same chain, but I was mostly concerned about the "prv, rsz, and mmap" elements, since those were the parts I couldn't get working. This example program set up a few more IOCTLs (for which the only documentation I could find was related to the 2.6.10 kernel version of the drivers... a bit out of date), so I figured I was missing yet more configuration. I attempted to adapt the code to configure my situation, but still my capture thread hangs in DQBUF.

Here is the code to set the whole thing up (note: it's a C++ app, the mediaDevice_ object has an overloaded [] operator to give me its entities by name and the >> operator handles linking magic... trying to help out readability for whoever inherits this code after I jump off a cliff from frustration :) ):

Another function calls the STREAMON ioctl, but when I go to DQBUF, that call never returns. I don't have this problem with the "DAVINCI VIDEO CCDC output", but that doesn't give me the right format for the encoder.

What am I doing wrong? Is this generally the correct method to do D1 composite capture and H.264 encode using TI's encoder on the DM365, or am I off the mark?

If the resizer has two outputs associated with the RSZ_S_CONFIG, which one ends up at /dev/video4? And, if it's output1, how do I configure it to be YUV420SP (there's no pix_fmt field for output1...)?

Thanks in advance for any help...

Hi,

Not sure which branch you are using as linux source use this branch

http://arago-project.org/git/projects/?p=linux-davinci.git;a=shortlog;h=refs/heads/dvsdk

in which NV12 support has been added. and for the examples refer this branch

http://arago-project.org/git/projects/?p=examples-davinci.git;a=shortlog;h=refs/heads/422-420SP

and refer resizer_ss.c which has support for NV12 support.

Thx,

Hi Prabhakar,

Thanks for your response. I am using the dvsdk branch of the linux-davinci repository.

I've seen the resizer_ss.c example, but that has the resizer working off of single shot mode using user supplied buffers. If I were to capture from the CCDC directly, then pass that buffer into the resizer in single shot mode and then pass the result from that into the encoder, I'd be incurring at least an extra buffer of memory overhead. It's not quite what I want. I'm wondering how to set up the capture pipeline so that I can stream NV12 frames directly from the video output node, with the resizer being chained off of the previewer and CCDC in continuous mode. Is this simply not possible with the DM365? I'd be a little baffled if TI wrote an encoder that doesn't work off of their own capture hardware without having to jump through hoops...

Thanks again; I'd appreciate any more insight.

Ryan

The attached application depicts NV12 output in continuous mode

([TVP7002]--->[CCDC]--->[PRV]--->[RSZ]--->[Video node] media pipeline)

You can use this application as reference and change accordingly as per requirement.

Frank,

as you have mentioned in DQBuf your application is not coming out, i doubt your interrupts are generating.

can you check wether you are gettinginterrupts or not inside your ISR by just putting some printk's.

Hi Prabhakar,

Thanks again for your help. I have adapted the file you sent; the only step I was previously omitting was setting the DV preset on the resizer output, which I set to V4L2_DV_480P59_94.

Unfortunately, it is still hanging in the DQBUF call. However, I did notice something in the kernel output that I hadn't before... there is an error message saying, "invalid mbus code" As far as I can tell, this comes from vpfe_capture.c in the mbus_to_pix function in the kernel. I modified the printk on line 153 to tell me which code is being specified, expecting to see 8211 for V4L2_MBUS_FMT_NV12_1x20, but instead it says the code is, "0". I have set the media bus format on every pin in the chain except for the resizer output sink (because it gives me an error if I try)... so I'm not sure where that 0 is coming from, but I would bet it's integral to the problem.

Any ideas? Thanks again for your continued help.

Hi Frank,

I have created a application as you need, [tvp514x]--->[CCDC]--->[PRV]--->[RSZ]--->[Video node]

This application is tested for PAL, If you need NTSC appropriately change it.

Attached is the application.

Hi Sujit,

I added the printks to vpfe_isr and vpfe_vdint1_isr in vpfe_capture.c, and I see that vpfe_isr is indeed being called (the one that is triggered off of VINT0), but my DQBUF still hangs indefinitely.

Any idea what might be the problem, in this case?

Thanks.

Prabhakar,

Wow, thank you for taking the trouble to do that. This application does indeed do what I want, and it works. I modified it to use memory mapped I/O and it still works. I am adapting the code into our existing framework, but still running into the DQBUF hang, even though VINT0 is firing as it should be. Our code is configuring things with the same parameters as yours, although in a slightly different order... I will try modifying the order to match yours if that is critical.

Thanks again, I will post my eventual success here. At least now I know that what I want to do is indeed possible!

Hi Frank,

Thanks Good to hear that it works.

May be in your case you are missing, the queuing of right size buffers,

because of which it keeps on waiting for DQBUF IOCTL.

Thx,

Hi Prabhakar,

Well, I have some interesting, and confusing, news: I changed the order of the configuration calls in our code to match the application that you wrote, and it worked! Except, it only worked for one run... the next time I ran the application, it again hung inside of DQBUF. Frustrated, I ran the application you generously provided just to check my sanity, and it *also* hung inside of DQBUF...

I rebooted the EVM, and at first our application failed to MMAP one of the capture buffers, then your application (which I modified to use MMAP instead of USERPTR) also failed to MMAP the last capture buffer. The next run, however, was successful, for both applications.

So, I tentatively have a working application, but it bothers me still that even your application sometimes hangs in DQBUF, and also these random MMAP failures that can be resolved by simply trying to run the application again...

I would appreciate any thoughts you might have on this, and once again thanks for your help.

Oh, and as for the buffer size, as you mentioned in your comment above, I use the size returned by MMAP from the driver, so it should be correct...

Hi Frank,

I tested the application which I provided to you, but I see no issues as you mentioned.

Hi Prabhakar,

Yes, it was pretty strange to have the application you provided hang; it hadn't done that before. I'm not certain what went wrong. It has not happened since.

Aside from the occasional video buffer allocation failure by the video capture driver, my application now seems to be working well.

Thanks again for all of your help!

Frank

Hi Prabhakar,

OK, one more problem: while testing performance of our application, I noticed that frames were being dropped fairly regularly (nominal framerate is 30fps). I went back to your test application, and ran it for 10 seconds, and noticed that it also dropped frames. In fact, in the log you attached above, you can see some of the frames have 40ms and one even 80ms in between them.

We can't really afford to drop frames for our application; do you have any insight as to why this is happening?

Best regards,

Frank

Hi Frank,

Not sure about your application, But the app which i had attached was performing

file operation(frames are written to file), If you can remove this file operation,

and check the exact frame rate achived.

Thx,

Hi Prabhakar,

Our application sends the captured frames to the H264 encoder, which then performs file I/O, but the capture portion runs in its own thread at the highest priority in the system. Even without the encoder or file I/O threads running, though, the capture rate was not keeping up.

I removed the 'fwrite' call from your application, and added the frame timestamp deltas to the output. The result is attached; there are several frame periods well into the 80ms range and beyond. Can you confirm this is the case for you, as well?

Just as an update, we found the reason we were still having frame drops: the camera connections at the camera side were loose! This was causing intermittent signal issues and thus dropped frames.

Thanks again for all the help.

Hi,

This thread seems to indicate, that the "dvsdk" branch is better to use than the "official" latest PSP-release supporting dm365 (using tag "v2.6.37_DAVINCIPSP_03.21.00.04")

Is that correct?

Thank you!

I'm not sure that the "dvsdk" branch is better, but I remember reading something about it being necessary for DM368. Maybe somebody from TI can shed some light on the subject. You might want to start a separate thread, though.
