Object detection with NPU - h264 streams - h264 camera - rtsp

avaf · July 23, 2023, 8:25pm

Update 2:

Added support for:

rtsp (h264)
rtmp (h264 / flv)
http (h264 / flv)
v4l2 (h264)

Unfortunately, i haven’t found a way to fix latency on rtmp and http, usually 5 secs.

Currently I only have access to rkr4.

avaf · July 25, 2023, 10:03pm

I tested it with X11. I had to remove some optimizations due to license issues, but still fine with X11. I am just facing some issues with raw h264 coming from cameras, rkdev2 keeps resetting from time to time with kernel 5.10.110 if using dma32 on 4GB, it does not happen with kernel 5.10.66. Looks like one will need to remove that on kernel 5.10.110 if the board has 4GB. But i think the code is ready to be published.

I fixed it here, and now I am able to render NV12 10-bit, NV15/NV16, so basically, HEVC and H264 are working here in my version.

BTW, @boogiepop, you should review (when possible) h264_rkmpp_decoder, it get stuck on a second session.

boogiepop · July 28, 2023, 9:08pm

what do you mean by the session?

avaf · July 28, 2023, 10:41pm

If you run it the first time, decoding is OK. Run the second time and it gets stuck. I think it puts the board in a somewhat unstable state, i couldn’t access the directory i was working on and after a reboot had to give permission to my user to access the directory tree (the one i was working…). I haven’t looked at the code but i ‘think’ some resetting or releasing is missing.

Update:
Perhaps is some video stream format causing this. Tried a few ones now and it seems OK.

When can I use this with frigate for object detection? And what are the requirements for this to run?

avaf · July 29, 2023, 8:47pm

frigate is python/docker, ff-rknn is C/C++ for performance. rknn with python is available long ago, i don’t know why there was no interest in integrating it into frigate. Most of the AI people here in the forum are python experts, i am not.

(https://github.com/avafinger/ff-rknn#system-requirements)
Note: Some pixel format breaks RGA3 if the board has more than 4GB of RAM, but it has been fixed, waiting to be pushed.

FFmpeg is getting ready for HW Encoding, it is not hard to add the encoder to it and make it a simple NVR, but for a real NVR it needs multithreading and some optimizations to be re-written.

avaf · August 5, 2023, 3:29pm

I played a bit more with ff-rknn on X11 and added some parameters to detect a single object.

DISPLAY=:0.0 ./ff-rknn -i ~/weston/apps/videos_rknn/vid-13.mp4 -x 960 -y 540 -l 960 -t 0 -m ./model/RK3588/yolov5s-640-640.rknn -b 40 -o bird -a 60

Where -a = confidence, and -b = alpha-blend mask

Some benchmarks showed still reasonable to display 12 streams and record a screencast at the same time. I tried to use the NPU SRAM to reduce DDR bandwidth described here: (https://github.com/rockchip-linux/rknpu2/blob/master/doc/RK3588_NPU_SRAM_usage.md) and ROCK 5B Debug Party Invitation but the results were not good.

avaf · September 1, 2023, 9:01pm

Here i push the results to an RTMP server and play back in real-time with ffplay.

Avinadad_Mendez · January 30, 2024, 3:20pm

The code is really useful, but recent SDL commits ( https://discourse.libsdl.org/t/sdl-sdl-syswm-h-has-been-removed-and-replaced-with-window-properties/47246 ) break the code.

Some older SDL commits ( https://discourse.libsdl.org/t/sdl-sdl3-with-hardware-acceleration-for-rockchip-platform-mali-blob/41325 ) also lack some other required functions

Maybe SDL3 is still too unstable. In any case, can you suggest a specific SDL3 commit where this code compiles and works? I will try some other commits in-between these 2

avaf · February 1, 2024, 12:45pm

I think SDL3 api is changing a lot.

Last commit i have:
a94d724f17d7236e9307a02ec946997aa192778e

The hardware acceleration for Rockchip is still applied on the latest SDL3 commit, but i think if you have Panfrost enabled this is really not necessary, it was meant for libmali and should be harmless.

Avinadad_Mendez · February 1, 2024, 1:01pm

Hello, thanks again for your code and your help

I have a couple of questions about the code:

I see it only supports H264. Does it not support Raw NV12? Is there some technical limitation? My camera stream is Raw NV12.

For hardware acceleration. Is it good enough to just have Open GL ES support during compile, or do I also need SDL_Rockchip to show up as ON ?

For some reason I am not able to get SDL_Rockchip appear as enabled during compile, even though I have full hardware acceleration on X11 and EGLFS on my board. I have to also say I am using RK3566 and I am compiling everything from Buildroot Cross Compiler, maybe I am missing a flag or something?

Thanks again for giving the community such a nice code!

avaf · February 1, 2024, 1:22pm

Not a limitation, a feature. It use DRMPRIME and dma-buf. It should be changed drom DRMPRIME to NV12 here:

github.com

avafinger/ff-rknn/blob/main/ff-rknn.c#L798


    }


    video = input_ctx->streams[video_stream];
    if (avcodec_parameters_to_context(codec_ctx, video->codecpar) < 0) {
        av_log(0, AV_LOG_ERROR, "Error with the codec!\n");
        avformat_close_input(&input_ctx);
        avcodec_free_context(&codec_ctx);
        return -1;
    }


    codec_ctx->pix_fmt = AV_PIX_FMT_DRM_PRIME;
    codec_ctx->coded_height = frame_height;
    codec_ctx->coded_width = frame_width;
    codec_ctx->get_format = get_format;


#if 0
    while (dict = av_dict_get(opts, "", dict, AV_DICT_IGNORE_SUFFIX)) {
        fprintf(stderr, "dict: %s -> %s\n", dict->key, dict->value);
    }
#endif

and modify drm_rga_buf to use virtual buffer instead of dma-buf, FFmpeg return vbuffer in NV12 format:

github.com

avafinger/ff-rknn/blob/main/ff-rknn.c#L173


                              const enum AVPixelFormat *PixFmt)
{
    while (*PixFmt != AV_PIX_FMT_NONE) {
        if (*PixFmt == AV_PIX_FMT_DRM_PRIME)
            return AV_PIX_FMT_DRM_PRIME;
        PixFmt++;
    }
    return AV_PIX_FMT_NONE;
}


static int drm_rga_buf(int src_Width, int src_Height, int wStride, int hStride, int src_fd,
                       int src_format, int dst_Width, int dst_Height,
                       int dst_format, int frameSize, char *buf)
{
    rga_info_t src;
    rga_info_t dst;
    int ret;
    // int hStride = (src_Height + 15) & (~15);
    // int wStride = (src_Width + 15) & (~15);
    // int dhStride = (dst_Height + 15) & (~15);
    // int dwStride = (dst_Width + 15) & (~15);

You probably using Panfrost.

dmesg|grep -i panfrost

Note: There some minor changes you should pay attention, like:

github.com

float prev_frmrate = 0.0; // avg frame rate
Uint32 currtime;
Uint32 lasttime;
int loop_counter = 0;
const int frmrate_update = 25;


enum AVPixelFormat get_format(AVCodecContext *Context,
                              const enum AVPixelFormat *PixFmt)
{
    while (*PixFmt != AV_PIX_FMT_NONE) {
        if (*PixFmt == AV_PIX_FMT_DRM_PRIME)
            return AV_PIX_FMT_DRM_PRIME;
        PixFmt++;
    }
    return AV_PIX_FMT_NONE;
}

github.com

avafinger/ff-rknn/blob/main/ff-rknn.c#L356


        else if (clr == 7)
            SDL_SetRenderDrawColor(renderer, 255, 255, 255, SDL_ALPHA_OPAQUE);
        else
            SDL_SetRenderDrawColor(renderer, 0, 0, 255, SDL_ALPHA_OPAQUE);
        SDL_RenderRect(renderer, &rect);
    }


    SDL_RenderPresent(renderer);
}


static int decode_and_display(AVCodecContext *dec_ctx, AVFrame *frame,
                              AVPacket *pkt)

    int ret;

Avinadad_Mendez · February 1, 2024, 1:40pm

Hello, thanks a lot

I am not using Panfrost, I am using libmali, but I might have had some old files pending clean-up along the way, I really experimented a lot when trying to get GPU acceleration. I will do a make clean and try again.

Avinadad_Mendez · February 1, 2024, 6:04pm

Hello, I tried make clean, and did make again, still no SDL_Rockchip.

I did “dmesg | grep -i panfrost” and nothing showed up

“– SDL_ROCKCHIP (Wanted: ON): OFF” This should be ON, correct? I am using Buildroot crosscompiler so maybe I am missing something

avaf · February 1, 2024, 7:18pm

Yeap.

Sorry. I can’t help with buildroot, i don’t crosscompile, i do everything natively.

I think you should change this line to be able to crosscompile:
dep_option(SDL_ROCKCHIP “Use ROCKCHIP Hardware Acceleration video driver” ON “UNIX_SYS;SDL_CPU_ARM32 OR SDL_CPU_ARM64”

Try:

dep_option(SDL_ROCKCHIP “Use ROCKCHIP Hardware Acceleration video driver” ON “UNIX_SYS” OFF)

Avinadad_Mendez · February 2, 2024, 3:07pm

It still doesn’t work, I’ll do my research. You’ve helped plenty already! Thanks a lot
