[PATCH] mf frames count
by Ötvös Attila 15 Apr '06

15 Apr '06

Hi All! I created small patch with mf stream. The new options: count = number frames of one image file Example: mplayer mf://jpeg_files/*.jpg -mf fps=25:type=jpeg:count=100 or mencoder mf://jpeg_files/*.jpg -mf fps=25:type=jpeg:count=100 -ovc ... Time until change image: 1/fps*count = 1/25*100 = 4s Create from 1 images to 10min time length video (eg. DVD menu): mencoder mf://jpeg_files/001.jpg -mf fps=25:count=15000 -ovc ... Best regards! Attila

Hi, This patch supresses zero-length frames being mistaken for keyframes during regeneration of the AVI index ("-forceidx").

[PATCH] fix realaudio in mkv
by Roberto Togni 03 Apr '06

03 Apr '06

Hi all, this patch adds audio packet descrambling to mkv demuxer and changes extradata to conform to the new ad_realaudio decoder interface. The same extradata format and packet order is also used by lavc real decoders. There is one problem created by this patch: in the old version the codec filled sh->i_bps (nAvgBytesPerSec) based on the flavor value, while now the codecs don't do it anymore (and that would not be possible anyway with the lavc codecs). In real demuxer i solved the problem by taking i_bps from the MDPR header, is there some field in matroska that can be used to fill that value? Else the only option is to create a table with bitrates like it's done for sipr codec (sipr is the only codec where flavor or bitrate is used to select the codec subtype). Only cook is tested (samples/Matroska/realaudio/nosound.mkv). Mosu, can you comment on this? Ciao, Roberto

.developer cruft
by Rich Felker 03 Apr '06

03 Apr '06

hey, i've been trying to clean up old/broken/etc. cruft in mplayer code an i realized the hated build system where everything gets rebuilt unless you touch .developer is still in place. as much as coreteam liked forcing users to perform such favors on them, i think it's time we remove the need for users to 'touch .developer' in order to have sane build dependencies. does anyone reject to: - removing support for .developer - fixing dependencies so that version.h is handled correctly. - moving the old .libdeps hack i added out of etc and making it part of the default makefile for automatic subdir dependency handling. - removing the dependency on configure that forces rebuild whenever configure has changed (it's wrong anyway since configure needs to be rerun first). ?? rich

[PATCH] asf demuxer fix
by Alban Bedel 02 Apr '06

02 Apr '06

Hi, i looked a bit at the asf demuxer. This whole thing with the asf descrambeling will also fail if several demuxer are opened at the same time. So while at it i fixed that too. Unless someone speakup i'm going to commit this patch in the next hours. Albeu

[PATCH] vd_ffmpeg: crash on changing colorspace and extradata handling
by Reimar Döffinger 02 Apr '06

02 Apr '06

Hi, attached are to patches to vd_ffmpeg. The first one avoids a crash when the colorspace changes during decoding (e.g. mf://*.jpg when the jpgs use different chroma subsampling, like 00.jpg and 04.jpg in incoming). This is done by properly reinitializing the vo in this case, so that the get_buffer function returns large enough buffers. The second patch passes extradata on as default, instead of having this large list of all codecs that need it. This one may be more reason for discussion (and testing) I guess. Greetings, Reimar Döffinger

Need help with interlaced images and strides
by Walter Belhaven 01 Apr '06

01 Apr '06

Hi, I'm attempting to implement a slight variation of the 'tinterlace=0' filter, and it's clear that I just don't "get" the stride implementation in mplayer, or just how interlaced images are stored. Can someone point me to some info on this? I've read everything I can find, including all of the technical documentation. I even think I understand the entire filter interface and most of what's going on in vf_tinterlace.c, but there's a disconnect somewhere. Here are the details. To convert 720p/60Fps HD "video" to 480i/60fps SD "video" for burning to DVD-Video (capital F's mean Frames, little f's mean fields), I'd like to take, say, the even lines from Frame 'j', and, say, the odd lines from Frame 'j+1'. At a high level this is what the tinterlace=0 filter does, but not quite. In order to test the concept and to get things working, I'm making my changes "in place" to tinterlace=0. The changes I've made are as follows: vf_tinterlace.c::config() 1. passed 'height' and 'd_height" to next filter, rather than height*2 and d_height*2 vf_tinterlace.c::put_image() 1. requested an image of 'mpi->height' instead of 2x that in vf_get_image 2. set 'dmpi->fields' to MP_IMGFIELD_INTERLACED. Also tried setting MP_IMGFIELD_TOP_FIRST. 3. changed all occurrences of dmpi->stride[n] to twice that value, in all calls to memcpy_pic. 4. changed all height's to height/2 in calls to memcpy_pic. I get core dumps if I don't, and it makes sense to me to make this change. 5. Used a single stride offset when copying the 2nd field I'm clearly missing something, because the resulting output doesn't look interlaced, especially with two carefully crafted JPG images I'm using for testing. Any help would be appreciated. Thanks, WB __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com

[PATCH] cmov detection and draw_alpha fixes
by Alban Bedel 31 Mar '06

31 Mar '06

Hi, since i added the box backgrounds in the osd menu i noticed a nasty bug with the draw alpha functions. They happily overflow leading to some nice distortions :/ So i went on to fix that, the mmx version are trivial to fix just change the final paddb to a paddusb. However for the generic i386 asm for rgb24/32 i didn't found a nice and quick solution w/o using cmov (their probably is or ?). So i used cmov and let the rest fallback on C. Sadly cmov is not present on all cpu, currently it is only used in lavc under a #if __CPU__ >= 686. However their are some 586 with cmov (for ex the AMD Geode which is a 586 with cmov and mmx). So i added a proper test to configure and cpudetect.c. Albeu
