[PATCH] Fix potential overflow in get_metadata
by Clément Bœsch 19 Dec '10

19 Dec '10

There is at least one potential heap overflow in mplayer.c:get_metadata: meta = malloc (8); sprintf (meta, "0x%08X", sh_video->format); So here is a patch to change the way "meta" is handled in this function. -- Clément B. Not sent from a jesusPhone.

[PATCH] Allow gmplayer the use of non-UTF-8 filename encoding
by Ingo Brueckl 19 Dec '10

19 Dec '10

Hi, so far, the gmplayer cannot handle non-UTF-8 filename encoding (but set to an arbitrary locale). The patch allows the (GLib) filename encoding to be in an arbitrary locale (given by gtk environment variable G_FILENAME_ENCODING), and the GUI dialogs will display and handle these filenames correctly.

[PATCH] proper version info for git.mplayerhq.hu
by Rudolf Polzer 17 Dec '10

17 Dec '10

I attached a small patch that, if mplayer is compiled from mplayer.git, uses the git commit hash instead of UNKNOWN as version info. The format will be: git-<commithash>-<gccversion> if mplayer is built from "master", and git-<closest commithash on master>-<commithash>-<gccversion> if mplayer is built from another branch. In my case, at the moment it prints: MPlayer git-15dfe0a-ceba2bd-4.4.1 (C) 2000-2010 MPlayer Team It changes nothing if run from a svn repository. Best regards, Rudolf Polzer

[PATCH] Use BUFLENGTH for buf defined in draw_image
by Marco Aurélio Graciotto Silva 15 Dec '10

15 Dec '10

In libvo/vo_png.c, the variable 'buf', used to create the output PNG filename, has a constant size of 100. However, vo_png.c already defines and uses a constant, BUFLENGTH, for a similar purpose at config(). So, I changed draw_image() to use BUFLENGTH instead of 100 as its size. Regards, Marco

MPlayer creates a "fake" Apple
by İsmail Dönmez 13 Dec '10

13 Dec '10

Hi; This is the most amusing bug I've ever encountered. Attached is a snapshot of MPlayer running on Snow Leopard, using corevideo as video output. Notice that there are two Apple logos, one real (the one on the left) and one a cheap imitation (the one on the right). I am wondering how this is happening :-) Regards, ismail

Output filename prefix for PNG output
by Marco Aurélio Graciotto Silva 12 Dec '10

12 Dec '10

Dear MPlayer developers, I was wondering if Mplayer couldn't add a prefix to the filename of the PNG created using PNG 'video' output. I searched the mailing list and I could find just one post regarding this (http://lists.mplayerhq.hu/pipermail/mplayer-dev-eng/2007-October/054281.html) but it was about writing everything to just one file (instead of several files). Thus, I created a small patch that allows the usage of a prefix for the PNG output filename. The new option is "outfile", which is used to define the 'png_outfile_prefix' variable. The default behaviour is the same as Mplayer currently has (default value for 'png_outfile_prefix' is an empty string), so backwards compatibility is kept. I also changed the BUFLENGTH value, so I could use the same value for the buffers at vo_png.c (they are all used for the same purpose, setting the name of the output path or filename). I also defined a saner value (255 as max path+file name) instead of the mixed 100 (as defined in 'draw_image' function) and 500 (as of 'config' function). Besides this, I also did minor indentation fixes. The patch was created against MPlayer svn #32678. Regards, Marco Aurelio

MPlayer linking takes forever on MinGW
by Georgi Petrov 06 Dec '10

06 Dec '10

Hi, Fresh msys/mingw (GCC 4.5.0), just installed. Fresh SVN revision of MPlayer, just downloaded. YASM added. Everything compiles fine, but the linking takes forever and never finishes. I tried waiting 2 hours on a very, very fast system. 2% CPU usage by ld.exe, 100MB/s writing to mplayer.exe and... nothing. I tried on my old msys/mingw 100% working configuration first (GCC 3.x.x) and the result was the same. I attach config.log, gzipped. Any ideas? I'm trying for 6 hours and I have no success so far.

Subtitles modules
by Clément Bœsch 04 Dec '10

04 Dec '10

Hi, subreader.c is huge file with lots of various, and I was planning to extract specific subtitles format functions into sub modules, just like libmpdemux, libmpcodecs, etc. So first step, I'd like to just put specific format functions into specific files: sub/st_jacosub.c sub/st_microdvd.c sub/st_sami.c sub/st_subrip.c ... This will be the first tricky thing since some formats have specific hacky global variable such as previous_sub_end. If I'm not wrong the second step would be to define some instance and info struct just like with at least init, read, postproc, dump and close function. The automatic type detection could be ported in the init function of each type. Does anyone has a grudge against this, or see a big obstacle? Regards, -- Clément B. Not sent from a jesusPhone.
