troubles compiling on cygwin, portability issues
by D Richard Felker III 31 Jul '02

31 Jul '02

I've been trying to compile mplayer on cygwin, and the process hasn't gone at all smoothly. First of all, mplayer's inttypes.h defines: typedef signed char int8_t; typedef signed short int16_t; typedef signed long int32_t; typedef signed long long int64_t; All of these should be good, but the stupid cygwin sys/types.h goes and defines the following conflicting types: typedef char int8_t; typedef short int16_t; typedef int int32_t; typedef long long int64_t; Bleh. Perhaps I managed to get an old version of cygwin on the computer I'm testing on (I'm not familiar with cygwin at all; I just used the setup program on the website to install it), so let me know if it's just something dumb on my end. A few other problems arose while I was experimenting with stuff. Now, it turns out my broken SDL was trying to force the build into mingw mode (eew), but I think these issues should still be fixed, since they might cause portability problems on other systems: 1) ao_mpegpes.c tries to include sys/ioctl.h, which doesn't exist. IMHO this should only be included when DVB is enabled; it's not needed for output to file. 2) spudec.[ch] use u_int and u_char typedefs. This is total nonsense -- it's just shorthand for "unsigned int" and "unsigned char" -- and so it should be fixed IMO. If no one objects I can commit cleanups for both these issues. Again, they should not be problems with cygwin in true cygwin mode (and I confirmed that they're not), but they could potentially cause trouble porting to other systems in the future. Now on to more problems. I can't seem to find any information on how to build a working cygwin copy of SDL. The broken SDL configure script builds the whole thing in mingw mode, which seems not to work with cygwin. Now, I know there's been success using mplayer on windows, so apparently someone knows how to get a working copy of SDL. Since this seems to be a nontrivial task it should probably be documented in the DOCS somewhere... Oh, and sorry for mixing user/dev stuff in this message; it's sorta hard to divide it up well. Rich

Y422P support
by Arpi 31 Jul '02

31 Jul '02

Hi, libavcodec has YUV 4:2:2 planar supoprt (PIX_FMT_YUV422P) used by the mjpeg decoder, and by teh deinterlace filter too. but, mplayer doesn't have IMGFMT for the _planar_ 422, the current vd_ffmpeg calls y422p->yuy2 converter to workaround it... we should introduce IMGFMT_422P or better, and add support for that in swscaler. afaik, teh swscaler can handle any planar yuv formats internaly, so this shouldn't be too hard to implement.

[PATCH] lavc deinterlace filter, try 2
by Joe Rabinoff 31 Jul '02

31 Jul '02

Hi, As per the recommendations, I wrote a simple filter, vf_lavcdeint.c, which adds support for avcodec's deinterlacer. It's based on vf_lavc.c and (loosely) on some ffmpeg code. It won't be compiled if USE_LIBAVCODEC isn't defined. The lavc deinterlacer works fine, although I honestly can't tell the difference between it and the builtin ones, at least on my test sequence. This is my first time working with the project, so you might want to check that I understood the architecture well enough not to do anything stupid. Please let me know if there are things I should change. Joe Rabinoff PS -- the mplayer code is fun to work with. Kudos to the designers.

[PATCH] screen width fix on vo_x11.c
by Kazunori Ueno 31 Jul '02

31 Jul '02

Hello. I'm Kazunori Ueno. % mplayer -vo x11 -xy 2 XXX.avi If the screen size of 'XXX.avi' is 320x240, this command should make the mplayer window and its size should be 640x480. But the option '-xy N' cause no effect with vo_x11 video output driver and the window size is not changed. Following patch fixes this problem. --- Kazunori Ueno / Univ. of Tokyo.

For some reason it doesn't like it at all on NT4. So, I have to disable. Same goes for GL, spits out lots of errors/warnings for GL on my system, mostly due to the fact I have NO GL support for my card. Can't use another card, this is not my personal machine... > Is someone working on DLL support ? I asked cygwin guys how to make > Windows API calls. I am slowly looking at it.

It shows EXACTLY how to get it working for you. I have included it below just for you. :) (and anyone else that doesn't have it that wants it...) > Rich > /S. Smith PS. Myself, Sylvain Petroelle (spelling?), and Atmos are all working kind of parallel on making mplayer work in cygwin. They are having better luck with getting patches applied, I guess. Occassionally I send one, look through the archives, there are several from me that will get you going. -- Get your free email from www.linuxmail.org Powered by Outblaze

[PATCH] configure: exit after wrong or misspelled options
by Diego Biurrun 31 Jul '02

31 Jul '02

Hi all! This trivial patch to configure makes it quit after stumbling over an unknown or misspelled option instead of just printing an error message and continuing. As some posts on -users lately showed this error message may get lost in the noise, so this hopefully helps avoid problems and spurious bug reports.

Hi, this is a small patch for the mplayer cvs version-string, so that the true last cvs update and not just the last cvs update in the top level directory is shown in the version-string. Andreas

FYI: multi-angle-dvd's
by Robos 30 Jul '02

30 Jul '02

Hi A short time ago someone asked what multi-angle dvd's are available. Today I received amazon.de's special offer which includes 2 multi-angle-dvd's, being: MIB - Collectors Edition and Hannibal. And they are rather cheap! ;-) http://www.amazon.de/exec/obidos/tg/feature/-/274578/ref=mm_prm_hv7sf_t_pr_4 Hope that was of interest, Robos
