Sketches (esp32-cam, rtos and rtos all frames) severe lag #7

Closed Captainoddvious closed 3 years ago

There is a huge amount of delay in the web stream through browser, 5-10 seconds and frame rate is very poor. With standard example webcam sketch i can get ~4-8 fps with uxga, is there something i am missing?

The only time I had this issue was due to a faulty esp32-can module. Some of them are really poor quality. As you can see on the video in this post, esp-eye was streaming with practically no delay at all to multiple browser windows....

I have it using two different t-camera v1.6.2 and am seeing quite a bit of lag with uxga. Depends on resolution camera is set to and whether you select allframes (which obviously spools), so I am getting by with VGA mode. Regardless, it looks to me as there is one task only handling all clients. Often, in threaded environments, a thread per connection is used. Is there much work in looking at a task per client? It may or may not help with the lag. Is it worth an experiment? Even if they might be xx.xx.xx.xx:81/1..10 for example (pretending to be 10 different cameras on different streams rather than 10 clients on one stream). Just brain storming ;)

It already creates a dedicated task per video stream. Please read the code before posting. I do not have severe lag on my esp-eye and esp32-cam modules, so not sure what is going on in your case. Sorry.

Cheers. Not fully tested yet. Understood.

Sorry - did not mean to be rude. I can only fix what I can replicate, and so far I was not able to. I observe a little lag at higher resolution, but still am able to stream at ~10-15 FPS. I attribute it to the latency of the PSRAM. The only time I had a really severe lag (it wasn't even a lag - it was not streaming at all) was some (probably bootlegged) esp32-cam unit. Never happened since. The network latency plays a role. If you streaming via the internet it will be slower. The fastest of course is on WiFi/same router.

I didn't take it as rude, so don't sweat that. I get you can't test everything. I will poke about to see what I can discover. You've provided some hints, thanks.

Anyway, not sure I am able to help here. Particularly I do not own the device you are using and it is not even listed as supported. What I observe is this: https://youtu.be/bsAVJSZeSmc A near-real-time performance on ESP-EYE (and slightly worse on ESP32-CAM)
