I think I found the problem. Evidently Logitech doesn't send standard MJPEG formatted video. I found this reference online:
The Logitech C270 webcam utilizes a proprietary, embedded H.264 stream within a Motion-JPEG (MJPEG) format. While MJPEG is a standard format, the C270 adds H.264 data to the ...

Decoding MJPEG From USB Camera (ESP32-P4)
I have an ESP32-P4 Function Board that I'm using to decode MJPEG data from a USB Logitech C270 camera. I have the UVC demo working and can see MJPEG images at about 25FPS over WiFi to a PC. I am trying to add code to display the video on the LCD that is connected to the eval board. When I attempt to ...

Re: ESP32-P4 Example Build Error
Instead of trying to build the demo project using my Windows 10 PC, I decided to try it on my Mac Mini M1. I was able to build the project without any issues using the exact same steps. I still need to figure out why Windows 10 won't build it for me, as this is my work computer and the Mac is my ...

Re: A2DP-Sink Audio Sample Rate (Need 48KHz)
I haven't solved this issue yet. I was able to connect at 48KHz SBC with my chromebook and my TV, so I know it can do 48KHz. I have tested many Android phones and IPhones and could only connect at 44.1KHz. I tried to use developer mode on the Android devices, but it always reverted back to 44.1KHz ...

A2DP-Sink Audio Sample Rate (Need 48KHz)
Using the A2DP-Sink project, I need to change the audio connection rate to 48KHz. I haven't had any success yet. It will only connect at 44.1KHz. Does anyone have any experience changing this setting?

Bluetooth (A2DP) Audio to Wifi (HTTP) Bridge Possible???
Is it possible to receive audio from a bluetooth source (such as a phone) and re-transmit it out the Wifi interface via HTTP so that multiple ESP32 boards could receive/decode the audio? Basically I want to the ESP32 to bridge my audio out as an "internet radio" device (aac or mp3). Does anyone have ...

ld_acl.c error
Does anyone have any idea what this error means?
ASSERT_ERR((((uint16_t)clkoff1 << 0) & ~((uint16_t)0x000007FF)) == 0), in ld_acl.c at line 302
I don't have ld_acl.c source file in my SDK. I guess it's inside a pre-compiled library.

ESP32 Development on a Pinbook Pro
In case you are interested in developing ESP32 IDF projects on a PineBook Pro, it does work. I just had to compile the xtensa tools on the PineBook Pro first. I use the "make menuconfig", "make", "make flash", and "make monitor" commands to configure, build, program, and monitor debug output from my ...

GPIO36 GPIO Input Glitches With BT/A2DP
I am using GPIO36 as a button input. It normally works fine. If I enable bluetooth audio I notice very fast pull-down pulses. These pulse occur about 0.5sec rate when BT A2DP isn't connected to my phone. When it initially connects to my phone, the glitches still occur at the same rate. If I then ...
