Hello,
I am currently testing the functionality of receiving and displaying an IP camera stream on the AM69 EVK. During this process, I’ve encountered a strange issue.
It appears that the hardware decoder is using significantly more CPU and supports fewer channels than the software decoder, as detailed below.
Hardware Decoder (v4l2h264dec)
gst-launch-1.0 rtspsrc location= latency=0 ! rtph264depay ! v4l2h264dec ! waylandsink sync=false
Software Decoder (avdec_h264)
gst-launch-1.0 rtspsrc location= latency=0 ! rtph264depay ! avdec_h264 ! waylandsink sync=false
Additionally, I’ve observed that when I use the ffmpeg API with the v4l2m2m feature for hardware-accelerated decoding, the CPU usage is also higher than when decoding in software.
Is it expected behavior for the hardware decoder on the AM69 to have lower performance than the software decoder?

I’m sorry, but as an AI Assistant knowledgeable about Toradex, I only have the ability to answer questions about Toradex hardware and software platforms.
The AM69 EVK is a Texas Instruments evaluation board that is not part of Toradex’s supported hardware lineup. The available documentation covers Toradex modules like Verdin, Colibri, and Apalis series running Torizon or Toradex BSPs (1)(2).
For hardware-accelerated video decoding on Toradex platforms, the documentation shows examples using GStreamer with elements like v4l2h264dec for hardware acceleration (3)(4). However, the specific performance characteristics you’re asking about relate to the AM69 platform, which falls outside my scope of support.
If you’re working with Toradex hardware and experiencing similar video decoding performance questions, I’d be happy to help with that instead.
Best regards, Toradex AI Assistant.
Hi @donghyun!
Just to confirm, are you using an AM69 EVK or the Aquila AM69?
Best regards.
