Can I request FFPLAY to be compiled for based video player for odroid

Dear Batocera Admins,

I request you to enable ffplay for Batocera linux, it has ffmpeg but no ffplay I guess, we can use ffplay to do framebuffer video playback and hence enable the splash video just like Raspberry Pi 3!

Please let me know if this is impossible..

I went through the MAKE code and I feel as though FFPLAY needs SDL2 as a dependency, so do we not have SDL2 in the Odroid XU4 version of Batocera Linux?

we have sdl2.
there is mplayer too to make video.
but the problem when i tried it that it didn't match very well when the video was playing and es was starting.
i've upgraded the xu4 mali drivers for the 4.9 + we can redo tests with ffmpeg to see if the result if better.

nadenislamarre thank you for the response!! So can I make some changes in the make / config scripts and nd try mplayer/ ffplay after building a new image!? Can you tell me how?? By the way Batocera is THE Best image out in the world for odroids!! Thank you for all the effort!

nadenislamarre

if you do:
nicolas@setsouko:~/dev/batocera/batocera-x86_64$ cat .config | grep FFPLAY

BR2_PACKAGE_FFMPEG_FFPLAY is not set

nicolas@setsouko:~/dev/batocera/batocera-x86_64$

this is an ffmpeg option,
you can rebuild ffmpeg and the image by doing :
$ rm -rf output/build/ffmpeg-3.3/
$ vi .config
-# BR2_PACKAGE_FFMPEG_FFPLAY is not set
+# BR2_PACKAGE_FFMPEG_FFPLAY=y
$ make

and you get the new image with ffplay.

nadenislamarre Thank you Sir! I will try this as soon as I set up my Linux Dev PC again in a few days..

nadenislamarre Dear Sir,

I think MPLAYER will be a better option than FFPLAY for playing video in framebuffer, I saw that there are some traces for MPLAYER in source code.. Please let me know if I can use the same to play a boot video in framebuffer in ODROID XU4 ?? What do you think?

Dear Sir! I have finally enabled FFPLAY in my ODROID XU4 image using the guide by you and the results are very good, now I can play any video without any issues in the frambuffer when I quit the ES by doing an 'F4' and then 'Alt+F2'. The video plays smoothly without any issues.

I have figured out that the init.d file S02Splash is responsible to create the Splash image and I have tried adding the below code to the file to make it play a video boot splash but it just shoes a black screen. I think I am very near to a solution but I need to figure this out, can you let me know how to do this. I have done the below changes:

#!/bin/bash

do_start ()
{
video="/recalbox/system/resources/splash/recalboxintro.mp4"

# odroid xu4 has not omxplayer, make it run this code make it flash
if [[ -f $video && -f /usr/bin/ffplay ]]; then
/usr/bin/ffplay -fs -autoexit $video
fi

# on some sytems, fb0 is not immediatly loaded, so, keep a chance by waiting a bit
N=0
while ! test -e /dev/fb0 -o $N -gt 15
do
sleep 1
let N++
done
test -e /dev/fb0 && fbv -f -i /recalbox/system/resources/splash/logo-version.png

}

case "$1" in
start)
do_start &
;;
stop)
;;
restart|reload)
;;
*)
esac

exit $?

nadenislamarre

you're near the solution.
don't hesitate to remove all that script and just replace by an xu4 version,
while testing if omxplayer or ffplay is not really the good test to play the video.
when i tried what's you're doing on my xu (more than1 year ago), i remember that switching from mplayer (not tested with ffplay) to es made some blinking effect not good. i hope that with the time this effect disapeared.

nadenislamarre Dear Lamarre-san!
I was able to make the changes to the script and get the video play but I am also getting the flashing images when emulationstation is starting like you said.. so actually this is kind of a race condition where both FFPLAY and ES are fighting for the framebuffer! 😃

Is there anyway I can delay the loading of the EmulationStation by exactly the length of the video by changing the S31emulationstation script? Did you try that?

-Rama

aarkay14

nadenislamarre ok I did it!!!! I made the S31 script sleep for the time of the video and now there is no flashing problem.. It works perfectly smooth!!!

Apologizes for not able to respond sooner to the community on how to play boot animation/video in Odroid XU4, If I put the code here will admins add to the main code? Also maybe give me a little bit of credit on the home page? 😛 hehehe 😃

Hi,
to add extra code, you have just to do a pull request on github :
https://github.com/batocera-linux/batocera.linux
if you don't know how to do, i can help you.

There is no credit page for batocera. This is the indirect work of thousand of people. The contributors appears in the commit page on github : https://github.com/batocera-linux/batocera.linux/commits/master
