Fansubbing with Linux in mind

[Starks]

And the patches created so far have been committed.

Greg. Once again, thanks a million.

[checkers]

No starks, thank you.

[Starks]

Eh? Aside from setting things in motion, I haven't done much to deserve thanks.

hello

mplayer -ass -vc ffh264vdpau /media/WDGP1TB-1/Macross\ Saga/plus/macrossplus1v3.mkv
.....
vo_vdpau: get_image failed003 ct: 0.044 0/ 0 25% 4% 1.4% 7 0
[VD_FFMPEG] Only buffers allocated by vo_vdpau allowed.
mplayer: libmpcodecs/vd_ffmpeg.c:1198: vdpau_get_buffer: Assertion `0' failed.

without codec works fine (using VDPAU output)

is problem of mplayer? or *vdpau codec...

thanks

[TheFluff]

try adding -vo vdpau

the vdpau (mplayer by nvidia) using vdpau output by default

I downloaded and built mplayer-export last night; the libass patches were included. The mencoder patch that Starks cites above also installed cleanly despite the changes to the libass source.

Any hints on a fansub that would put the new libass patches to the test? I have the Ubuntu Intrepid release version in /usr/bin and the newly-compiled version in /usr/local/bin so I could do some side-by-side comparisons.

The patch by nvidia (3402051) don't support ASS, so remove the -ass from the command line.

From the error message the file need more NUM_VIDEO_SURFACES_H264 than the 17 allocated by vdpau.

Can you give some info about your file, number of reference frame, number of bframe and if bpyramid is used.

im used mplayer by nvidia (3402051) compiled with ASS patch (http://greg.geekmind.org/mplayer/mpl...-ass-2nd.patch)

how to view this info from video?

the video without ASS patch works (without subs) (with/out ffh264vdpau (using vdpau output))

the video is the release Macross plus by KAA

[Miles Teg]

If it's the same file that I have (crc=667016D2) we have 16 ref frames, 5 bframe, b_pyramid

I can play the video with ffh264vdpau with a little change in vo_vdpau.c

ligne 96 of mplayer-vdpau/libvo/vo_vdpau.c should be :

#define NUM_VIDEO_SURFACES_H264 17

Change the 17 to 18, save the file, and recompile (a make will suffice) and normally the file should play (that work for me)

[sl1pkn07]

ok, it works. but other videos fault

GITS , metropolis, tekkon kinkret, Jin-Roh, a my goddess,... all 720p by Thora

VO: [vdpau] 1280x720 => 1280x720 H.264 HIGH VDPAU acceleration
Error 25 at libvo/vo_vdpau.c:1107 0.000 0/ 0 23% 9% 1.3% 6 0

is the problem surfaces? how to view these parameters? (bframes, reference frames, etc)

greetings and thanks

What is the difference between a build snapshot and mplayer-export?

[martino]

IIRC export is the result of doing 'svn export' which will download only bare sources without the metadata.

Error 25 is too much reference frame for the resolution (720p, I think it's something like 9)

If you don't care about the restriction of level 4.1 go to line 751 of mplayer-vdpau/libvo/vo_vdpau.c you should find :

    switch (format) {
    case IMGFMT_VDPAU_H264_MAIN:
    case IMGFMT_VDPAU_H264_HIGH:
        {
            // FIXME: Use "h->sps.ref_frame_count" here instead.

            // Level 4.1 limits:
            uint32_t round_width = (vid_width + 15) & ~15;
            uint32_t round_height = (vid_height + 15) & ~15;
            uint32_t surf_size = (round_width * round_height * 3) / 2;
            max_references = (12 * 1024 * 1024) / surf_size;
            if (max_references > 16) {
                max_references = 16;
            }
        }
        break;
    default:
        max_references = 2;
        break;
    }

After that and before the if (IMGFMT_IS_VDPAU(image_format)) simply write :

max_references = 16;

With that mplayer will always initialize 16 reference frames for all of your video, if the player still won't play (error 23) then your out of video RAM and nothing can be done (with 512Mb 16ref@720p ok but only 8 ref@1080p).

To know about all ref frame and all those thing open your video file with an hexa editor and search for the string x264 and you will have all the info, a program call mediainfo can also do that.

brother... are you the fucking master

VERY THANKS!

all videos works perfect!! 720p, 1080p and 480p!! with subtitles!!

Sounds right. The file mplayer-checkout-snapshot.bz2 at http://www.mplayerhq.hu/MPlayer/releases/ is about twice the size of mplayer-export-snapshot.bz2. Upon expanding, I see the checkout version has lots of .svn directories not present in the export version.

I just discovered the Kumaji project. I am salivating.

http://www.aegisub.net/2009/02/kumaji-explained.html
http://kumaji.sourceforge.net/

If you want to check out the code.

svn co https://kumaji.svn.sourceforge.net/svnroot/kumaji kumaji

Or view online...
http://kumaji.svn.sourceforge.net/viewvc/kumaji/

[jfs]

Before any misconceptions are created: Kumaji is useless in its current state.
It's nothing but a basic rasterisation framework for vector graphics and some test-cases and a single hacked together proof-of-concept text rendering program. There isn't much resembling subtitles in it, however that doesn't mean it's doomed or whatever, it just means it needs more work. I would love to get some real assistance (software design, code review or programming) for it, but read the blog post.

[Starks]

jfs. perhaps you should copy that message into a new topic.

[sl1pkn07]

hi!

the new version of mplayer by Nvidia include the ASS patch!!!

but not apply the Miles Teg patch
