How to configure H.264 encoder bitrate when using H.264 encoder as part of the ISP graph

mrosar11 — Fri, 12 Jun 2026 15:30:13 GMT

We would like to know if the bitrate used for H.264 compression is configurable in the VSDK or if it is hardcoded when using the H.264 encoder as part of the ISP graph?

Hello @mrosar11,

I was not able to get an exact answer for your question with the available documentation.

I will raise this topic with the internal team and I will get back to you once I have their feedback.

Regards

Hello @mrosar11,

I have have received feedback from the internal team. You can configure the bitrate according to your needs using the mBitsPerMbrw member of the H264ENC_Config_t struct, for instance, you could add the following line in the isp_sonyimx224_h264enc sample project:

Let me know if you have more questions.
