[SOLVED] Sony Bravia - Aspect Ratio fixing

_Updated 01/08/2012_

The following is just a discussion on what has to be implemented in future Serviio versions (version 1.0) for this to work. You won't be able to pass any custom parameters to FFmpeg as of now.

Since version 1.0 Serviio use the following solution (2) , it was implemented and fix the Sony Aspect Ratio issue.


I worked on ffmpeg option to use for Sony Bravia TV Aspect Ratio fixing.

1) This is the best solution
- no need to use the zoom option on Sony Bravia Menu
- All pixels are displayed
- Correct Display Aspect Ratio
- But there is a CPU overhead for the upscaling into hd resolution

ffmpeg option to use with AVI files <720 height resolution
With DAR > = 16:9
"-vf "scale=1280:1280/dar/sar","pad=1280:720:(ow-iw)/2:(oh-ih)/2:black","setdar=4:3"
With DAR < 16:9
"-vf "scale=720*dar*sar:720","pad=1280:720:(ow-iw)/2:(oh-ih)/2:black","setdar=4:3"



2) An alternative - same that PS3 Media Server/Mencoder option -, resulting less cpu overhead, but some pixels (16) are lost on left and right side !!
- add padding to have a 16/9 aspect ratio (top/bot or left/right depends of the source format ratio)
- Change DAR=4/3

-vf "pad=max(iw,ih*16/9):max(ih,iw/16*9):(ow-iw)/2:(oh-ih)/2:black,setdar=4:3"

Explain:
With DAR > = 16:9
-vf "pad=iw:iw/16*9:(ow-iw)/2:(oh-ih)/2:black","setdar=4:3"
With DAR < 16:9
-vf "pad=ih*16/9:ih:(ow-iw)/2:(oh-ih)/2:black","setdar=4:3"


3) Workaround for testing purpose

I found out that the TV doesn't deal with non-HD stuff properly! so I need to expand/upscale to a HD : 1280x720 resolution.

Re: Sony Bravia - Aspect Ratio fixing

For the moment, this is the ffmpeg option I use (simplify: no need to know the input resolution):

-vf "scale=1280:-1","pad=1280:720:(ow-iw)/2:(oh-ih)/2:black","setdar=4:3"

- The original file is scale into HDTV format with 1280 pixel width, and same input DAR(1280x1280/inputDAR)
- Then padding with black bar to a 16:9 display ratio (1280x720)
- And DAR is set to 4:3 ratio.

see FFMPEG documentation
for details.

Re: Sony Bravia - Aspect Ratio fixing

Zip, do you think we could add an "FFMPEG Custom Options" to the ffmpeg command line when transcoding is used (like PS3 Media Server with mencoder custom option : Such as "-vf softskip,expand=::::1:16/9,dsize=4/3") ?
I already opened a ticket for that feature : https://bitbucket.org/xnejp03/serviio/i ... n-renderer

Example of ffmpeg custom option : -vf "scale=1280:-1","pad=1280:720:(ow-iw)/2:(oh-ih)/2:black","setdar=4:3"
In fact, that could be a first step for Sony Aspect ratio fixing.

I'd rather Serviio generating these values based of the file information and profile automatically.

OK, so now I'll look for other input resolutions (1920x1080).

Re: Sony Bravia - Aspect Ratio fixing

Brilliant findings illico, one of the biggest issues with the Sony Bravia TVs is this, it affects when playing .avi and streaming video with latest beta.

I dont mind a temporary fix, can you include this custom ffmpeg code on Sony tv profile to be injected when it's executed?

Re: Sony Bravia - Aspect Ratio fixing

I have this same problem on my Sony KDL 40EX403. The 1024x576 MKV files (which get transcoded as AVC) look perfect though - excellent picture quality and correct aspect ratio.

Re: Sony Bravia - Aspect Ratio fixing

I just installed Mezzmo Media Server to test and they use FFMPEG as their transcoding engine and they fixed the aspect ratio for Sony Bravia
This proves this can be done with ffmpeg

A temp option whilst you figure out how to do it dynamically would be great. I gotta say Serviio is by far the best DLNA server out there. I've looked at them all. The only thing missing for me is transcoded M4V/H265+AC3 into MPEG-PS+AC3 having the correct aspect ratio. I've got it working with MediaTomb with the "-aspect 16:9" option. So I switch back and forth as needed, but try explaining that to my wife.

Here's my script in case it helps...

#!/bin/bash
INPUT="$1"
OUTPUT="$2"
DAR=`ffprobe -show_streams "${INPUT}" | grep -m 1 'display_aspect_ratio' | awk -F= '{ print $2 }'`
FPS=`ffprobe -show_streams "${INPUT}" | grep -m 1 'avg_frame_rate' | awk -F= '{ print $2 }'`
AC3_TRACK=`ffprobe -show_streams "${INPUT}" | grep ac3 -B10 | grep 'index=' | awk -F= '{ print $2 }'`
/usr/bin/ffmpeg -y -i "${INPUT}" -threads 2 -g 15 -vcodec mpeg2video -sameq -acodec copy -map 0:0 -map 0:${AC3_TRACK} -copyts -aspect 16:9 -r ${FPS} -sn -f vob "${OUTPUT}"

I should've clarified...this is the script I call for my MediaTomb setup. MT allows you to call an arbitrary script and pass two parameters (input and output filenames). Thought it could help Serviio devs.

Re: Sony Bravia - Aspect Ratio fixing

I don't know why Sony don't fix this aspect ratio issue.
Ps3ms have to manipulate MEncoder to play the correct ratio
I don't how Mezzmo uses to manipulate ffmpeg, but have noticed the encoding compared to Serviio is under par, so much jaggies on edges, it's like watching an old Playstation One game!
Never tried MediaTomb but I'd like stay with Serviio as my ONLY one stop shop media server.
Would be great if this can be fixed as I hate pressing zoom on remote every time a file is transcoded.

So far, so good. I did try to do it programmatically by querying the DAR and then using that. I found that some files didn't have this set and decided to just brute force it to 16:9. I'll freely admit I'm a total hack and sure there's a better way with some error checking. e.g. use DAR when possible and then use 16:9 when all else fails.
