Hi Rajesh, thank you for using picam!
Please just replace the picam binary with the newer version and everything should work fine. Also make sure that libcamera is enabled instead of the legacy camera stack.

FYI, picam 1.4.9 works on Raspberry Pi 4 if the legacy camera stuck is enabled in raspi-config > Interface Options.

Hi iizukanao, Thankyou so much for your prompt response, I am in a remote village from last two days, where my internet was not working so i could not see your answer, I will inform you to confirm after implementing your suggestions. Thankyou once again🙏🙏🙏🙏🙏 Rajesh

Hi iizukanao, Your picam version 1.4.9 is based on buster and there is only legacy camera support till buster I suppose, please correct me if I am wrong🙏🙏

You are correct. Bullseye is required to use libcamera.

• picam v1.4.9 is for legacy camera stack (Buster and Bullseye)
• picam v2.0.x is for libcamera (Bullseye)

Thankyou iizukanao, but does that mean that version 1.4.9 cannot be used with pi 4, as I am using the latest picam-streamer, which uses picam version 1.4.9 and does not work on raspberry pi 4 ? 🙏🙏🙏🙏

If you manually upgrade the OS and picam to the latest version, it should work on the Raspberry Pi 4.
