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, 

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.
