RTSP Camera Streaming Failure for 2K/Above Full HD Resolution on NXP i.MX8M Plus FRDM (4GB RAM)

[Kaustubhnaik45]

The RTSP camera streaming pipeline using GStreamer on the i.MX8M Plus FRDM board (4GB RAM) fails when processing high-resolution video streams (2K or above Full HD).

The system successfully initializes the pipeline and establishes an RTSP connection. However, during playback, the pipeline terminates with the following errors:

• Internal data stream error
• streaming stopped, reason not-negotiated (-4)
• Could not write to resource (Received end-of-file)

This issue is observed specifically with high-resolution (≥2K) H.265 streams, indicating that the platform is unable to negotiate or sustain the required decoding pipeline.

Key Observations:

• GStreamer pipeline works for lower resolutions (e.g., 1080p)
• Failure occurs during caps negotiation or decoder stage
• Hardware decoder (v4l2h265dec) likely hitting limitations
• System is running:
  • Linux Kernel: 6.6.x (scarthgap)
  • Yocto-based NXP BSP
• Board configuration: i.MX8M Plus FRDM with 4GB RAM

Hi,

Thank you for your interest in NXP Semiconductor products,

This issue is regarding the encoding/decoding operations for H.265 2K frames, i.MX 8M Plus supports only 1080p as seen in the documentation.

Hi,

Thanks for confirming that i.MX 8MPlus supports H.265 up to 1080p@60fps.

Could you please clarify whether the device can decode a 2560×1440 (1440p) H.265 stream at a very low frame rate (e.g., 5 fps)?

Is the 1080p limit a hard resolution limitation of the VPU hardware ?

Hi, 

First of all, thank you for your reply.

Based on your clarification that the i.MX 8M Plus supports only up to 1080p . I would like to ask if you could suggest any alternative suitable processors or development boards  that supports 2K (1440p) RTSP streaming, particularly .

Thank you in advance for your guidance.

Hi @Kaustubhnaik45,

Please refer to i.MX 95 Reference Manual,

The VPU domain consists of a H.264/H.265 VPU codec, a motion JPEG encoder, and a motion JPEG decoder for image and video compression applications.
