Homebrew Homebrew app [Release] Video player for 3DS

Core_2_Extreme said:

Yes.
But on OLD3DS use 144p because the resolution is too high for OLD3DS to decode.

Yes, 800px mode is enabled. I mostly notice the artifacts when a video has a lot of red in it, almost like the resolution of the color is half rez or something no matter what scaler I've used (Nearest, Bilinear, Lanczos).

Super sampling down from resolutions higher than native makes that particular issue go away, though in recent testing it doesn't seem to make too much difference beyond that when I use good scaler.

If you want to watch youtube video on your 3ds, you can use thirdtube (developed by @windows_server_2003)

On NEW 3(2)DS, it is recommended to use patched Luma3DS for better performance.​

Performance
Decoding speed depends on encoder option, video type, video scene, etc...
This table shows average fps, so you may hear stutter audio if you use this framerate.
(Lower video resolution or framerate in that case)
Software decoding in this table uses only one thread not multi-threaded decoding.

3D conversion guide V2
i fully automated the command so you only need to change the INPUT and it will do everything else for you

if you have nvidia maxwell gpus or newer (+- GTX 960 and newer) you can use hardware acceleration version of commands to speed up the converting a lot.
replace the INPUT at the beggining with your movie file name. dont change ANYTHING else.
it will spit you out movie1.avi and movie2.avi
For videos and films longer than 1 hour and 30 minutes, use these commands:

Code:

ffmpeg -i INPUT -vf scale=800:240:flags=neighbor scaled.mkv && ffmpeg -i scaled.mkv -filter_complex "split[l][r];[l]stereo3d=sbsl:ml[left];[r]stereo3d=sbsl:mr[right]" -map [left] -map 0:a -c:a copy left.mkv -map [right] -map 0:a -c:a copy right.mkv && mkdir 1 && mkdir 2 && ffmpeg -to 1:30:00 -i right.mkv -c:v copy -c:a copy .\1\right.mkv && ffmpeg -to 1:30:00 -i left.mkv -c:v copy -c:a copy .\1\left.mkv && ffmpeg -ss 1:30:00 -to 3:00:00 -i right.mkv -c:v copy -c:a copy .\2\right.mkv && ffmpeg -ss 1:30:00 -to 3:00:00 -i left.mkv -c:v copy -c:a copy .\2\left.mkv && ffmpeg -i .\1\left.mkv -i .\1\right.mkv -map 0:v:0 -map 0:a:0 -map 1:v:0 -vcodec mjpeg -b:v 3M -ac 2 movie1.avi && ffmpeg -i .\2\left.mkv -i .\2\right.mkv -map 0:v:0 -map 0:a:0 -map 1:v:0 -vcodec mjpeg -b:v 3M -ac 2 movie2.avi

Hardware accelerated version:

Code:

ffmpeg -i INPUT -vf scale=800:240:flags=neighbor  -c:v h264_nvenc -maxrate 100M -b:v 12M -minrate 6M scaled.mkv && ffmpeg -i scaled.mkv -filter_complex "split[l][r];[l]stereo3d=sbsl:ml[left];[r]stereo3d=sbsl:mr[right]" -map [left] -map 0:a -c:a copy -c:v h264_nvenc -maxrate 100M -b:v 12M -minrate 6M left.mkv -map [right] -map 0:a -c:a copy r-c:v h264_nvenc -maxrate 100M -b:v 12M -minrate 6M ight.mkv && mkdir 1 && mkdir 2 && ffmpeg -to 1:30:00 -i right.mkv -c:v copy -c:a copy .\1\right.mkv && ffmpeg -to 1:30:00 -i left.mkv -c:v copy -c:a copy .\1\left.mkv && ffmpeg -ss 1:30:00 -i right.mkv -c:v copy -c:a copy .\2\right.mkv && ffmpeg -ss 1:30:00 -i left.mkv -c:v copy -c:a copy .\2\left.mkv && ffmpeg -i .\1\left.mkv -i .\1\right.mkv -map 0:v:0 -map 0:a:0 -map 1:v:0 -vcodec mjpeg -b:v 3M -ac 2 movie1.avi && ffmpeg -i .\2\left.mkv -i .\2\right.mkv -map 0:v:0 -map 0:a:0 -map 1:v:0 -vcodec mjpeg -b:v 3M -ac 2 movie2.avi

if you have video shorter than 1 hour and 30 minutes use these commands

Code:

ffmpeg -i INPUT -vf scale=800:240:flags=neighbor scaled.mkv && ffmpeg -i scaled.mkv -filter_complex "split[l][r];[l]stereo3d=sbsl:ml[left];[r]stereo3d=sbsl:mr[right]" -map [left] -map 0:a -c:a copy left.mkv -map [right] -map 0:a -c:a copy right.mkv && ffmpeg -i left.mkv -i right.mkv -map 0:v:0 -map 0:a:0 -map 1:v:0 -vcodec mjpeg -b:v 3M -ac 2 movie.avi

hardware accelerated version:

Code:

ffmpeg -i INPUT -vf scale=800:240:flags=neighbor -c:v h264_nvenc -maxrate 100M -b:v 12M -minrate 6M scaled.mkv && ffmpeg -i scaled.mkv -filter_complex "split[l][r];[l]stereo3d=sbsl:ml[left];[r]stereo3d=sbsl:mr[right]" -map [left] -map 0:a -c:a copy -c:v h264_nvenc -maxrate 100M -b:v 12M -minrate 6M left.mkv -map [right] -map 0:a -c:a copy  -c:v h264_nvenc -maxrate 100M -b:v 12M -minrate 6M right.mkv && ffmpeg -i left.mkv -i right.mkv -map 0:v:0 -map 0:a:0 -map 1:v:0 -vcodec mjpeg -b:v 3M -ac 2 movie.avi

And if you wonder why it needs to be split in two, why not just lower the bitrate...
If you put the 3hour movie into the 4GB, it would look like this...

Nice JPEG ヾ(•ω•`)o
that why it needs to be split into two

if you have MacOS or Linux, you need to convert it manually

Spoiler: OLD GUIDE

SPLITTING (skip if your movie is shorter than 1 hour and 30 minutes)
3DS uses Fat32 which has max 4GB file size. Avi needs at least 3Mb/s with the resolution that 3ds uses to look averagely good (6Mb/s with the 2 video tracks)
with that bitrate, it can fit only fit 1 hour and 30 minutes. but most movies are longer. so we need to split it. use these commands

Code:

ffmpeg -to 1:30:00 -i YOURMOVIE -vf scale=852:240:flags=neighbor -c:a copy part1.mkv

Code:

ffmpeg -ss 1:30:00 -i YOURMOVIE -vf scale=852:240:flags=neighbor -c:a copy part2.mkv

hardware accelerated version

Code:

ffmpeg -to 1:30:00 -i YOURMOVIE -vf scale=852:240:flags=neighbor  -c:a copy -c:v h264_nvenc -minrate 5M -b:v 12M -maxrate 100M part1.mkv

Code:

ffmpeg -ss 1:30:00 -i YOURMOVIE -vf scale=852:240:flags=neighbor  -c:a copy -c:v h264_nvenc -minrate 5M -b:v 12M -maxrate 100M part2.mkv

do the following commands to both parts of your movie
3d in video files is side by side in one video track. we first need to extract the 3D into two separate video track so we can convert it to the format that 3ds needs
select either the side by side command or top/bottom command based on your source video

side by side video:
open command prompt in the same directory as your media file, and copy the command, and change INPUT to your video files

Code:

ffmpeg -i INPUT -filter_complex "split[l][r];[l]stereo3d=sbsl:ml[left];[r]stereo3d=sbsl:mr[right]" -map [left] -map 0:a -c:a copy left.mkv -map [right] -map 0:a -c:a copy right.mkv

hardware accelerated version:

Code:

ffmpeg -i INPUT -filter_complex "split[l][r];[l]stereo3d=sbsl:ml[left];[r]stereo3d=sbsl:mr[right]" -map [left] -map 0:a -c:a copy -c:v h264_nvenc -maxrate 100m -b:v 18m -minrate 10m left.mkv -map [right] -map 0:a -c:a copy -c:v h264_nvenc -maxrate 100m -b:v 18m -minrate 10m right.mkv

top/bottom video

We need to convert the top bottom video to side by side video

Code:

ffmpeg -i INPUT -vf stereo3d=abl:sbsl -c:a copy output.mp4

hardware accelerated version:

Code:

ffmpeg -i INPUT -vf stereo3d=abl:sbsl -c:a copy -c:v h264_nvenc -b:v 20m -maxrate 100m -minrate 10m output.mp4

now you have side by side video. use the command in "side by side video" section to separate it


now we have the separate left eye video track and right eye video track
The actual conversion
in this step, we take the left eye video and right eye video and put it into 1 file with two video tracks that the 3DS consumes

Code:

ffmpeg -i left.mkv -i right.mkv -map 0:v:0 -map 0:a:0 -map 1:v:0 -vcodec mjpeg -s 426x240 -b:v 3M -ac 2 movie.avi

Copy the output file onto your SD card and play it

Cropping the leterboxing so its 16:10 and fill whole screen (OPTIONAL] (DONT DO THIS IF YOU ARE NOT WELL FAMILIAR WITH FFMPEG!)
the video will be stretched, but will fill the whole screen
first, export some frame from the left/right video. then open the frame with gimp (can be photoshop). select everything except the black borders
copy the information about the selection, and paste it into this command (replace out_x with the selection width, out_y with selection heigh, X and Y with the start position of the selection)(replace the LEFTRIGHTVIDEO with your source movie source):

Code:

ffmpeg -i LEFTRIGHTVIDEO -vf "crop=out_x:out_y:x:y:" crop.mp4

follow the code in left/right video to separate the files into left right files

Would people be interested in "GUI" version of the 3D convertor? And it could also convert 2D videos into the correct format? (so you dont need to duck with ffmpeg?) https://gbatemp.net/threads/release-video-player-for-3ds.586094/post-9575227

Well, 4 months after promising the GUI, i finally got time to do it
it will be able to take input video, and convert it to standard video, hori hd video, and 3ds video, and it can take both left/right and up/down 3D videos. It can also output to mjpeg, mpeg and h264.
you can also select which downscale do you want to use, either lanczos, nearest neighbor, or "mix" (downscales to double of 3ds resolution with lanczos, and then downscales to 3ds resolution with neighbor)
In the future, i am gonna also add a wii mode, which converts videos for WiiMC

Small disadvantage is that its Windows only (since its made in C# and Windows Forms), but if someone uses linux, he propably knows how to use command line...
