Streaming Video From an SD Card on the ESP32.

Turned out to be a bit easier than expected - we can now play video from the SD Card! Once again we're using my custom PCB from www.PCBWay.com/?from=atomic
I really need to get a new board designed and manufactured - it's getting a bit bonkers now with all the wires...
The GitHub repo with the code is here: github.com/atomic14/esp32-tv
The Cheap Yellow Display I mentioned at the end of the video can be got here: s.click.aliexpress.com/e/_DFo...
It really is remarkably cheap for what you get. Audio needs a bit of tweaking, but it works.

Had posted this question earlier, but it seems yt sadly censored it because it had a URL. Can have a look at this S3 board design I made and clarify what needs to be changed about it (if anything), aside from adding boot and reset buttons and a better USB port? Thanks in advance!: oshwlab dotto commo/allonesuncorp/esp32-board (Yes, the dotto commo is a . and a com)

[@OMNI_INFINITY]

PS: Can TwoWire do 3 i2c bus instances or is it called TwoWire because it can only make 2? Trying to add an OLED to an ESP32 project that already has 2 sensors on 2 TwoWire i2c buses.

[@carljay4021]

How can I find this board?

[@ChunkySteveo]

Awesome work, as always, Chris! Keep up the great work!!!!! My daughters have requested several versions of the tiny tv already!!

[@atomic14]

Get them the bits and set them building their own version :)

Great ad always- i’ve been waiting to binge these!

[@raevod6361]

I absolutely love this video, please keep it up.

[@atomic14]

Thanks! More videos in the works - though I won't have quite as much time over the next few months.

[@petebowcott8348]

Brilliant, thanks for this Atomic14

[@atomic14]

No problem - glad you liked it :)

[@lastmagmarian9116]

Fun fact: The particular adapter you are using already has the grounds connected.

[@atomic14]

As soon as I read your comment I did think "doh, they'd have to be connected, they are both ground" - so easy to miss obvious things!

[@BrianLough]

Awesome work!

[@atomic14]

Thanks Brian!

[@SinanAkkoyun]

Yes, another gem of a video!

[@atomic14]

Thanks!

[@arunsp4576]

I've been watching all of your videos recent times and you are really 👍 awesome i got plenty of knowledge from you sir ☺️ i would like to thank you for providing the stuffs which I've been stuck for a long time

[@atomic14]

Thanks! That’s great to know.

[@PsychogenicTechnologies]

Cool, nice work! Going to be interesting updating the files on that hardwired SD card... maybe stream from the network, hah :-)

[@atomic14]

The micro SD can be popped out from the adaptor. What would be really nice though is the ESP32 acting as a mass storage device when it's plugged in. Not sure if that's possible with an S3.

[@BRUXXUS]

Oooh, I'd like to try making a little wearable pin that plays videos! That could be a fun project. Maybe a little screen on a hat? :) Thanks for these fun projects!

[@atomic14]

I've got a round display that I think would make a really cool badge. In theory, you could fit everything on a PCB behind it including the battery.

[@BRUXXUS]

@@atomic14 That could be so cool! I do live streams on Twitch and have a hat with some little ws2812b LEDs, and chat can control the colors and effects. I think it would be really fun to let them be able to play GIFs on a badge with a screen. :)

[@SojournerDidimus]

Another crazy idea: "precompile" the video decoding on the PC, pushing effectively an ARM executable onto your SD card dedicated to this exact video playback.

[@zoenagy9458]

wow ton of work!

[@atomic14]

Thanks! It was a fun project and came together surprisingly easily.

[@rklauco]

Now you can use the same AVI format for streaming :)

[@atomic14]

Might work - though AVI is definitely not designed for streaming. It could work a nice intermediate format though - maybe preprocess the videos into it before streaming.

[@carlatashkadeh5890]

Very cool!

[@atomic14]

Thank you!

[@piconano]

There are only a few ESP32 modules with built-in colour LCD I know of; MaTouch series, DIYmalls 3.5", and LILYGO T-Display (without the SD card or touch). I think I'll buy a DIYmalls. It's so damn impressive for only CAD $40 I plan to make a Wifi monitor for my security camera running RPi-Cam-Web-Interface. Thanks for the inspiration.

[@atomic14]

The Cheap Yellow Display is very cheap - search for "ESP32-2432S028R" the audio is a bit crap, but there are some hacks to make it much better.

[@piconano]

@@atomic14 bought the "MaTouch_ESP32-S3 Parallel IPS with Touch 4.3" [google search] Made by same people at makerfabs but with an ESP32-S3, IPS capacitive touch... Cheap enough to give it a try. Keep up the great work.

[@atomic14]

Great - there are so many really nice modules out there at really reasonable prices. And having everything already wired up removes so many annoying bugs with breadboard and dodgy jumper wires.

[@piconano]

@@atomic14 Agreed. Also, I wouldn't be able to build one for that price.

[@jovialcupid9687]

Google "esp32c2 7" AliExpress"' They are relatively cheap, 30$

[@ethzero]

Very nice 👍

[@atomic14]

Thanks!

[@bk-go6905]

What is the spi clock speed with LCD? What is frame rate, and are you redrawing the entire screen every frame?

[@atomic14]

We're running the SPI at 80MHz and getting 15fps - with some tweaking I think we could reach 20-25fps. The whole screen is redrawn for each frame.

[@kerogre256]

I got a very bad experience with mosquitoes this year and decide I will make laser zapping auto aiming using microphones(using 4xESP32 as microphone ) in the room to triangulate position of flying mosquitoes .... I know i know it absurd but I need to try it, and it prabobly will not work due latency(all need to be done under 0.002s)

[@atomic14]

That sounds absolutely fantastic!

[@pwbarrett7]

I've built the project to use the CYD - is there anything else I need to change to use the SD card instead of streaming?

[@atomic14]

In the platformio.ini file Ithink it’s already set up to use the SD Card. You just need to select - cheap-yellow-display configuration when you build. If that’s not working can you raise an issue on GitHub repo.

[@argentinomacrifuevidaltamb3772]

Excellent video, it works!!!! I have the cheap-yellow-display and it doesn't go more than 5 frames per second, any way to improve it? Thank

[@atomic14]

There’s a weird conflict at the moment with enabling DMA on the display and using the SD Card. Need to investigate what the issues is as it feels like it should work.

[@argentinomacrifuevidaltamb3772]

@@atomic14 Ok perfect, thanks for your quick response. Congratulations, your work is excellent. Best regards✌

[@argentinomacrifuevidaltamb3772]

@@atomic14 I found this in a forum post SDcard and display use the different pins for spi interface. Display uses HSPI_HOST and DMA channel 1. SDCard uses VSPI_HOST an DMA channel 2. Change the DMA channel in the SDCard.cpp file this: ret = spi_bus_initialize(spi_host_device_t(m_host.slot), &bus_cfg, SPI_DMA_CHAN) ; for this one: ret = spi_bus_initialize(spi_host_device_t(m_host.slot), &bus_cfg, 2) ; SPI_DMA_CHAN fixed to 2. This changed a lot and the video is displayed much better with almost no frame loss. When the video is very long after 4 minutes it gets a little slow but very little I don't know if it is the final solution but the change is significant. Stay tuned to your comments. Regards

[@argentinomacrifuevidaltamb3772]

@@atomic14 Corrected, in larger videos I only lower the quality and it works smoothly on the yellow screen.

[@CharlieAmezquita-fc4vx]

You should use a amplifier, because the esp32 will prob struggle with audio out

[@jonathanr4242]

Can you use CYD or Clem's big yellow display?

[@atomic14]

Yep, it should work on pretty much any ESP32 board - the CYD is pretty handy as it's got the SD Card and display.

Can you attach a battery with it and make it portable And also mention the power consumption while it is running I need this information because I am doing a similar type of project like almost 80% same Please respond it will help me

There’s a battery charger on the board. I have no idea how much current it draws when running.
