How to implement RTSP streaming using IMX RT1170

Ragnar — Tue, 31 Oct 2023 12:25:49 GMT

Hello,

I want to stream the OV5640 camera that comes with the IMX RT1170-EVK board through Ethernet in the VLC player via RTSP protocol. To do that I have gone through the below examples "evkmimxrt1170_lwip_httpsrv_bm_cm7" and "evkmimxrt1170_enet_1g_txrx_multiring_transfer_cm7" but I'm unable to send the camera data buffers as input. So, I would like to know the following:

1. How to create the RTSP server or else is there any SDK example for that if there is any please mention that?

2. How to configure the camera data output buffers as input to that RTSP streaming?

Regards,

Ragnar.

Hi @Ragnar,

I'm afraid we do not have any example code or use case that has enabled an RTSP server with any of our i.MX RT devices and therefore I'm unable to provide support of this feature. The most I can provide for you is this knowledge base article that includes an application note describing the development for H.264 video decoding on an RT device: https://community.nxp.com/t5/i-MX-RT-Knowledge-Base/Application-Note-AN12562-Development-of-H-264-video-decode-on-RT/ta-p/1114085

That said, the i.MX devices are proven and have many more resources about this topic. As clients usually go for these devices for streaming over RTSP:

Sorry for the inconvenience this may cause.

Hello @EdwinHz ,

No problem, isn't there any way to display the camera data in the web page using IMX RT1170 as they done here https://dronebotworkshop.com/esp32-cam-intro/ in the ESP32-cam, and isn't there any other way in IMXRT1170, to transfer streaming data through Ethernet. Any example which streams through Ethernet will be helpful for us. Thanks for your reply.

Regards,

Ragnar.

Hi @Ragnar,

The implementation you seek of video streaming via ethernet with an RT device is definitely possible, we just do not have any implementation example that uses RTSP. However, you can take a look into the SDK examples for our solutions like the SLN-TLHMI-IOT-RD based on the RT1170 series or the SLN-VIZNAS-IOT which is based on the RT1060 series. These solutions are more approximate to the ESP32-cam you mention, and both have WiFi enablement. Although we do not have any example code specific for the RT1176, I recommend you to take a look into the SLN-TLHMI-IOT-RD SDK.

BR,
Edwin.
