Please add a binary image we can directly flash on ESP32 using the flashtool.

I have installed the esp32 requirements and i get an error on compile for this:

AudioVideoExample:3:21: error: soc\rtc.h: No such file or directory
 #include <soc\rtc.h>
                     ^
compilation terminated.
exit status 1

An anybody help?

Hello

I read the comments on your Youtube page.

I'm curious to know if any of those comments have given you ideas that might lead to the display in color?

thanks

Hi Bitluni,

I have posted this on your Patron as well, I hope you don't mind me posting here too.

I have tried the Composite video on my -ordinary TV- and it works perfectly but when I try it on a car monitor device like this one: https://www.amazon.co.uk/gp/product/B0056WJP1M it shows the image but flashes on and off about twice a second, would you have any idea why this would be?

I have also tried a FPV screen and had similar results.

Thanks for any help or advice.

Anthony.

Could the image2header conversion happen directly on the esp32 and so allow for example to convert the image from an esp32-cam directly to a composite tv or would that be too much processing for the esp32 to do that in real time?

(Sorry for asking this here but maybe someone has an idea how to do that :)

I'm getting such a fussy signal on one of those small CRT TVs:
https://www.youtube.com/watch?v=3TDNHkneLm0
Playing around with VHold and whatnot, this is literally the best I can get it.

Does anyone have advice about what to try? Perhaps capacitors somewhere? Resolution change doesn't seem to help

It's weird because normal composite video feed from, say a raspberry Pi 1 / camcorder, etc is just fine so I can't imagine what's different with this?

example:
http://www.rinkydinkelectronics.com/h_utft_fonts_101.php

It just displays monochrome video and not like grayscale, same result in both pal and ntsc on same tv

I have used CompositeVideoSimple example as video source for 5.8GHz FPV transmitter, but it does not work correctly. The signal is there but it is somewhat unstable. I can see part of the image on one frequency, another part on another frequency, sometimes whole image for a few seconds. I have tried 3 different transmitters a none of them work and when I use common camera as a source the image is crystal clear. Tried to change PAL/NTSC, resolution but it does not help. Looks like something is out of sync. Can you recommend me some parameter I could try to change ? Thank you...

Hello,

I read that the ESP32-D2WD has 2 megabytes of embedded flash memory.

Would this be usable as graphics memory for your ESP32CompositeVideo project or would it be too slow?

I have an old camera with composite video out. And I think to start use it.

Sorry for my English. 😄

I was wondering if I could use a external dac since the esp32 s3 doesn't have one.
like this one from adafruit: https://www.adafruit.com/product/935 ?
I already have it I just need to know how if possible

I noticed that the compiler errors/warnings exist in version 2.0.0 of the esp32 core for Arduino IDE, but in versions 2.0.4, 2.0.3 (2.0.2 and 2.0.1 not tested), it just doesn't display anything. 2.0.0 still works though.

Hi,

I want to be able to synchronize this to an external video signal so I can generate an OSD overlay.

But the synchronization part is seemingly impossible!

I'm made a test circuit with an LM1881 sync separator and I have modified the composite output library so that the clock source for the I2S DMA is set to the APLL. I can then modify the APLL registers with rtc_clk_apll_enable() and have very fine frequency control over the I2S DMA output.

I then wrote a Phase Frequency Detector type PLL 'loop' in order to lock onto the external VSYNC signal. It compares the VSYNC pulse to when data is written I2S DMA and tries to get them into sync by adjusting the the APLL regs and hence the frequency that the data is pushed out.

I can get reasonably close to a 'lock' but no matter what I do there is always about 1 line of jitter which is not acceptable for drawing an OSD.

I also tried a 'dumb' solution where the external VSCYN simply triggers the function to write to the I2S buffer but this still jitters badly....

Anyone with an ideas, please help, I am stuck :(

I have an ESP32 WROVER and I have found if I even enable PSRAM the system loses sync and the text slowly moves down the screen.

I am not sure as to why as the buffers should still be in main ram unless arduino-esp32 changed the functioning of malloc in respect to PSRAM lately.

Hello, just uploaded buth sketches (unmodified) from this repo onto my Sparkfun ESP32 dev board. It keeps rebooting, here is the serial monitor output:

I just got this program to play with it, but it doesn't work the first time.

Arduino version is 1.8.5. Not sure about ESP32 core version, but I downloaded that into Arduino/hardware manually. If I remember correctly, I downloaded it from the ESP32 Arduino core github.

You probably don't need this, but here are my upload settings:

Flash Mode: QIO
Flash Size: 4MB
Partition Scheme: Minimal (tried also with Default, same problem)
Flash Frequency: 80Mhz
PSRAM: Disabled
Upload Speed: 921600
Core Debug Level: None

I can't imagine there would be any recursive behavior or large stack allocations to cause this, so it seems pretty odd.

Unfortunately I just downloaded this and I have zero understanding of the code thus far.

Here is the zip I downloaded. The only modification I made was to the sketch name, just to make it more unique. I do not think that would be the problem though.

Hello,
I have no image on my DVD car player screen which has a composite input.
The FabGL library and ESP_8_BIT library both give me a correct output ("esp32-dali-clock" project works), but because I really enjoy the tutorials from your youtube channel I would like to stick to your library to develop projects on my esp32
I use latest version of arduino ide, and a esp32 devkit
I tried both PAL and NTSC, they both don't work.
Regards and thank you for all your work ! :)

please help

The analog video standard can be "hacked", that instead of 480i/576i, 240p/288p image can be displayed. It works that instead of the image alternating between even/odd lines each frame, its always sent to even lines instead.
Could it this feature be added into this software? (Its currently running in 240p anyway, but the image is send as interlaced, so it flickers. the progresive mode could reduce the flickering a lot)
