#4344 new defect

XSUBs are too low in PAL video, on PS3

Description

Hi,

I'm making test with subtitles, and when I try to convert a PAL VOB to Xvid with embed subs (idx/sub to xsub) it looks ok in VLC, but stretched and off the screen in PS3.
It seems that only happens with videos with height over 480 pixels, because 720x480 subs are ok in PS3.
It's like the PS3 thinks the bitmap subtitle are 720x480 and stretches them to 720x576, so lower subs are off the screen.

Does the "-scodec xsub" encoder has any options?? I didn't find any info about xsub encoder, nor any parameters in FFMPEG documentation.
Are the bitmaps fullscreen or clipped? Is there a way to set position of subs?

It's like the bitmaps are 720x576 but marked somewhere as 720x480??

Summary of the bug:
How to reproduce:

ffmpeg -i input -scodec xsub output
ffmpeg versión N-70148-g418be7c
built with gcc 4.9.2 (GCC)

Currently, FFmpeg has almost nothing to manipulate the contents of subtitles (either bitmap or text, for that matter). If your source had a certain resolution, then most likely the output file will have subtitles with the same resolution, and there are no options to change that.

I don't know if it's a bug of DivX subtitles, because I remember also happened with AVIAddXSubs, but it can change the Vertical Position of subtitles.

But, in the source code https://www.ffmpeg.org/doxygen/0.6/xsubenc_8c-source.html I think there are x, y, width and height parameters. It should be possible to change them, although subs may be higher in VLC, but they will look ok in PS3.

comment:3 Changed 17 months ago by edumj

With DivXMux.exe the subs are Ok, and it always makes Subtitle Track of 640x480 with any video resolution (like 720x540). May be that's why subs are too low if ffmpeg takes 720x576 as the sub resolution, when xsubs should be always 640x480.

There should be some way of passing xsub_encode fuction width and height parameters (and not let it take video source resolution) or just make xsubs always 640x480 like DivXMux does.

PD: It doesn't happen only in PS3, also in TV's and DVD's.

If you want to help with this ticket, please provide the FFmpeg command line that produces the incorrect output together with the complete, uncut console output (and point to the input sample) and, if possible, a "correct" output from the same source.

Ok, I will, but I found this sample in your samples directory https://samples.ffmpeg.org/sub/small.divx and they have the same problem: ok in VLC, but too low in TV (half off the screen).

Ok, I found this VOB in yours sample folder:

https://samples.ffmpeg.org/sub/starwarssub2.vob

It's PAL and has lots of Vobsubs.

I convert it to AVI, scaling video to 720x400 (with scale filter) and embeding XSUBs with this:

"ffmpeg.exe" -palette "000000,000000,000000,000000,000000,000000,000000,000000,000000,000000,000000,000000,000000,111111,ffffff,000000" -i "starwarssub2.vob" -map 0:v -map 0:a:0 -map 0:s:1 -scodec xsub -f avi -c:v libxvid -b:v 1500k -vtag XVID -c:a libmp3lame -b:a 128k -vf scale=720:400,setsar=sar=1/1 "starwarssub2 a xsub, scale 720x400.avi"

This is the output:

Appart from the fact that with "-s", setsar filter doesn't seem to work, the only difference I see in the output is:

with -s option:

Stream #0:2: Subtitle: xsub (DXSB / 0x42535844), 720x400

with scale filter:

Stream #0:2: Subtitle: xsub (DXSB / 0x42535844)

Does the -s option try to scale subtitles?

Because the subtitles looks the same (only looks different in VLC, and only if I don't scale video). But all of them looks the same and are too low (half off the screen) in TV.

PD: That doesn't happen with IDX/SUB createad with TXT2Vobsub, neither with NTSC DVDs, so it seems to happen only with PAL DVDs.

Please provide a "correct" variant of the same file.

comment:8 Changed 17 months ago by edumj

I made this with Divxmux starwarssub2 (.vob).divx but using different IDX/SUB, because without IFO the only way to extract Vobsub from a VOB, is with Mencoder, and with IDX/SUB extracted by Mencoder, DivxMux? freezes!

If you want the exact subs, this is another test with a PAL DVD:

"%~dps0\ffmpeg" -palette "ffffff,000000,444444,ffffff,000000,000000,000000,000000,000000,000000,000000,000000,000000,000000,000000,000000" -i "%~1" -map 0:v -map 0:a:0 -map 0:s:2 -scodec xsub -t 60 -f avi -c:v libxvid -b:v 1500k -vtag XVID -c:a libmp3lame -b:a 128k "%~dps0\%~n1 720x576.avi"

And the output:

And the subs are bad:

VTS_01_1 720x576 ffmpeg.avi -> Bad! (ffmpeg+xsub)

But, if I extract Vobsubs with PgcDemux? in .sup format, convert .sup to idx/sub with sup2vobsub and mux into .avi with DivxMux?, the subs are Ok:

VTS_01_1 720x576 paDivxMux.avi -> AVI without subs (ffmpeg)

VTS_01_1 720x576 DivxMux.avi -> Ok! (ffmpeg+PgcDemux?+sup2vobsub+divxmux)

Convert to AVI with ffmpeg (without subs):

"%~dps0\ffmpeg" -i "%~1" -map 0:v -map 0:a:0 -t 60 -f avi -c:v libxvid -b:v 1500k -vtag XVID -c:a libmp3lame -b:a 128k "%~dps0\%~n1 720x576 paDivxMux.avi"

Please run the following two command lines and test the output files:

$ ffmpeg -i VTS_01_1\ 720x576\ DivxMux.avi -scodec copy -acodec copy -vcodec copy out1.avi
$ ffmpeg -i VTS_01_1\ 720x576\ DivxMux.avi -scodec xsub -acodec copy -vcodec copy out2.avi

How do they play compared with the input file?

comment:10 Changed 17 months ago by edumj

They are Ok. XSUBs keep same size and position as the input file.

I supose ffmpeg always keeps xsub original size (640x480 re-scaled by DivMux?), but if vobsub has an original size of 720x576 (PAL DVD Subpictures) without re-scaling, they are too big for a xsub.

I think XSUBs where made not thinking on PAL... and only right resolutions are 640x480 or 720x480, because NTSC DVDs look Ok!

comment:11 Changed 17 months ago by edumj

One more strange thing:

With same IDX/SUB (made with Txt2Vobsub or extracted from NTSC DVDs) muxed with ffmpeg or divxmux, they look different in VLC (x and y position):

ffmpeg:

divxmux:
http://i47.photobucket.com/albums/f169/edumj/Starship_Troopers-ccextractor-xsub-divxmux%20640x480.png

But in TV, only y position is different!

ffmpeg:
http://i47.photobucket.com/albums/f169/edumj/Starship_Troopers-ccextractor-xsub-ffmpeg%20720x480%20oacute%20720x576iquestiquest%20en%20TV.png
divxmux:
http://i47.photobucket.com/albums/f169/edumj/Starship_Troopers-ccextractor-xsub-divxmux%20640x480%20en%20TV.png

And they are the same size, even ffmpeg says they are 720x576:

Stream #0:2(es): Subtitle: xsub (DXSB / 0x42535844), 720x576 (default)

I don't know which size are really IDX/SUB made with TXT2Vobsub in .sub, but in .idx it says 720x576 (it's not reliable), and may be that's why ffmpeg says that?

ffmpeg:

"ffmpeg" -palette "000000,000000,ffffff,ffffff,000000,000000,000000,000000,000000,000000,000000,000000,000000,000000,000000,000000" -i "ccextractor.idx"	-i "Starship_Troopers.vob" -f avi -c:v libxvid -b:v 1500k -vtag XVID -c:a libmp3lame -b:a 128k -c:s xsub "Starship_Troopers-ccextractor-xsub-ffmpeg.avi"

So, nor divxmux neither ffmpeg resize subs? But some flag tells VLC to change position and size (sometimes they are stretched!), but PS3 or standalone players doesn't use them... and then why only changes vertical position??

PD: With PAL, it must be sup2vobsub who resizes PAL VobSubs? to ???x???...

Does attached file show subtitles with correct size on your TV?

comment:13 Changed 17 months ago by edumj

No, I only see upper subtitles, lower gets cutted.

I'm pretty sure subtitles get cut at 480.

Does your TV only allow playback of PAL and NTSC mpeg4 asp in avi or also random resolutions?

comment:15 Changed 17 months ago by edumj

Well, the PS3 allows AVIs with higher resolutions, I've tried with 1440x1080 and XSUBs, and the subs were very small... And any other resolutions (720x540, 700x400, 720x400, 640x... etc..)

I also tried with 2 LG DVD Players, and 3 different televisions (CRT, LCD, and 4K LG Smart TV) so, the problem it's not the TV nor the Standalone Players. It's something about XSUBs resolution specification.

Did you tested it in your TV? Mine are all PAL. Anyone can try if it happens also in NTSC Players?

I can make PS3 captures if you want.

Do you know how to extract bitmaps from .sub? Subrip doesn't seem to work very well with idx/sub, and I can't keep them full size (always cropped).

Also, I could author a NTSC DVD and a PAL DVD, and put 720x480 and 720x576 subpictures, for testing size or offset changes...

comment:17 Changed 16 months ago by cehoyos

I wanted to ask you to test what happens if you put xsub subtitles into videos with both higher resolutions like 1440x1080 and much lower resolutions than pal or ntsc but I don't have command lines to test right now.

comment:18 Changed 16 months ago by edumj

Ok, with lower video resolutions (like 320x480 and 640x480) they are also cutted, and look exaclty the same size as with 720x576.

Wiht higher resolutions (like 1440x1080 and 1920x1080) they are full but smaller, because they are scaled down and top-center aligned (if I made them with DivMux? they also scaled down, but appear in an upper position because of their 480 height)

I can make some captures if you want.

Txt2VobSub makes 720x576 and 720x480 IDX/SUB (acoording to "size" in .idx file), but I found out that they really are 720x576 always and they just get cutted when .idx says "size: 720x480" (because the lower parts of the bitmaps are empty and it's ok to cut at 480). I mean, they must know that the max height for XSUB is 480 and they don't put subtitles lower tan that.

I'll try what happens with DivXMux and full height 720x576 VobSub? extracted with Mencoder, because when I extract them with PGCDemux and convert to idx/sub with sup2vobsub, upper subs go down and I don't know if DivXMux scales down to 640x480 or just aling bottom (but then the upper subs should be cutted!?)

comment:19 Changed 16 months ago by edumj

I've tested, and it seems that DivXMux does this:
1-Crop every bitmap (like SubRip?).
2-Pad them to 640x480 (bottom center aligned).

VLC captures with a yellow drawbox to see subtitles full size:

DVD Subtitles extracted to IDX/SUB are 720x576:

IDX/SUB Subtitles converted to XSUB with DivXMux are 640x480:
http://i47.photobucket.com/albums/f169/edumj/IDX-SUB%20to%20DivXMux%20640x480.png

You can see original upper subs go down with DivXMux because of the cropping an padding (but text is same size). They look not well bottom-centered in VLC, but ok in TV.

I don't know if ffmpeg can do this automatic cropping and padding to 640x480, but at least it could scale them down to 720x480 or 640x480 (or just "-1:480" to keep AR and because in TV they seem always top-centered, so no matter the width?).
