FT900 play video demo issue
« on: June 05, 2018, 05:46:24 PM »

Hello,

I downloaded the AVI playback demo inside the EVE demo page but I found the following issues:

  • SD card filesystem mounting crashes without modifying the code (moving it after FT900_Config();)
  • The LoadImageMFifo(); function stays looped for whatever reason

I did modify the definitions for my MM900EV3A with the 7 inch 800x480 display (newheaven)

I appreciate any help

Hello,

Yes there is a problem with this example on the website. I am waiting for it to be updated.

For now you can find the modified example at the following link, including the files that need to be placed on the SD card for this example to run:

FT_App_PlayVideo_SD_Fix.zip

FT_App_PlayVideo_SD_Files.zip

The example runs ok and the SD card can be mounted:

Code: [Select]

Welcome to Video Player Example ...

---------------------------------------------------------------------
 SD Card inserted!
 Mounted successfully.


Now I would like to point to a better example here:

FT81xLiftDemoWithVideo

We do have an additional edit that does full screen but that's not available on the FTP site yet.

This example demonstrates how to use more of the video features of EVE.

Also note that EVE is not primarily optimised as a video player so there may be compromises between video size and frame rate.

Best Regards,
FTDI Community

Hello, I will try the fix and the lift demo.

Well I'd say EVE works very well in video playback, even at 60fps! My coworkers are impressed by the performance.

Could you notify me when the new demo is available in your FTP?

Regards

Excuse me intrusion, recently in MCU of great features such as STM32F767 or Teensy 3.x we have made to play videos of resolution 795x475 pixels with audio.

I have used the examples of the administrator a few messages above, and I do not see fluidity in these files. I have to remember, with an application to convert .avi files with sound, the minute goes up to only 13MBytes, while the examples of FTDI and without sound, every minute is 100MBytes ...

The fps used is at 25, great quality.
The audio is compressed in Mu-Law Mono with sampling frequency of 8000Hz

In this link I put the file for your test. https://drive.google.com/open?id=1uCh_utiiPVWy4C01Xd7Hyqv1T31byWtL
This file of 1 munute and 21 seconds, only 24,5MBytes

In fact, we have used the special library from our repository; https://github.com/FT81xMania/GD23ZU

Regards.
