How to get time and length of file?
by shane bradley 22 May '03

22 May '03

I am writing a java application for mplayer. Most people are saying why use java....I am doing this has a grad project of sorts. I use Mplayer as an engine of sorts. My question are this: 1) I use slave mode to interface with mplayer(props to mplayer for that), I can run the commands that I need with that. The only problem is how do I retrieve the current time and total length of file. I am reading standard in, is there some way to pipe just the time out? 2) Also is there a way to get the info of a song, such as Artist, Genre...etc. with Mplayer? 3) Another thing, is there a way to start Mplayer without the info that comes up every time you start the app? later, shane Bradley Go Canes... _________________________________________________________________ Help STOP SPAM with the new MSN 8 and get 2 months FREE* http://join.msn.com/?page=features/junkmail

[BUG] segfault with some mpg with main-cvs - not with 090-cvs
by Pierre Lombard 22 May '03

22 May '03

Hi, I've uploaded to mplayerhq ftp two mpg samples that crash mplayer main cvs but they work with the 0.90 branch: seg11_with_mpcvs-ok_with_090.mpg (1) seg11_with_mplayercvs_ok_with_mplayer090.mpg (2) I've tried several compilation options, the distro is a debian sid. If it can't be reproduced, please tell me, I'll submit a proper bugreport. (1) I've not the sample underhand right now but I'll send the backtrace if the crash can't be reproduced.

patch for previously described bug
by Greg Stark 17 May '03

17 May '03

So I'm not sure if this video file is corrupt or if there's a bug elsewhere but it seems read_video_properties() doesn't check its arguments at all. I'm a bit puzzled why no video stream is found but I don't really have any solid evidence that there is a valid video stream either. I added a check for the lack of a video stream and now at least I just get a clean exit: ASF: No video stream found. ASF: No audio stream found -> no sound. Video: Cannot read properties. No stream found. Exiting...

Still getting seg fault on end of every video
by Greg Stark 17 May '03

17 May '03

Am I the only one still seeing this seg fault on the end of every video? This seems to be the same old config parser bug where it uses a string constant somewhere in setting up the config structures and then some other component tries to overwrite it. I've been seeing this bug continuously since, oh, a few months ago. This is from a fresh checkout from CVS with ./configure --enable-smb --enable-dvdnav --enable-menu --enable-gui --enable-live #0 0x409b102b in memcpy () from /lib/libc.so.6 #1 0x080b3082 in copy_opt (opt=0x84151a8, dst=0x8376520, src=0x855cbd8) at m_option.c:42 #2 0x080b2e99 in m_option_set (opt=0x84151a8, dst=0x8376520, src=0x855cbd8) at m_option.h:236 #3 0x080b2115 in m_config_pop (config=0x8555ab8) at m_config.c:121 #4 0x080a26a6 in play_tree_iter_step (iter=0x855bf18, d=1, with_nodes=0) at playtree.c:558 #5 0x0809acc5 in main (argc=6, argv=0xbffffc94) at mplayer.c:3483 -- greg

Audio channels messed up in 6 channel mode
by Zoltan Hidvegi 15 May '03

15 May '03

When I play 5.1 ac3 audio, the audio channels are mixed up. Initially, the Center/LFE is swapped with the rear surround, however seeking during playback can rotate the outputs. I've uploaded a sample to ftp://mplayerhq.hu/MPlayer/incoming/6.1_test.avi. Play it, and seek back a few times at the beginning to see the soud output moving between speekers. This happens with mplayer-0.90rc5 as well as with the current CVS. I use alsa-0.9.2, and it happens both with -ao alsa9 and with -ao oss (using alsa oss emulation). My motherboard is the Asus A7N8X deluxe, and I'm using the integrated nForce2 audio. The mplayer -v output is included below.

[BUG] segfault with very long file names in 0.90-cvs and main-cvs
by Pierre Lombard 15 May '03

15 May '03

Hi, Looks some stack overflow in playtree I guess (already reported a few months ago). The playtree code does not seem most obvious to me so if anyone more fluent with it could check this... I don't have the exact project name underhand but the mplayer mozilla plugin folks should add some URL length check if not already done. The tests are done on a K7 and IIRC there was some report that they did not crash on PPC. *With 0.90-cvs: mplayer `perl -e 'print "A"x99999'` segfaults #0 0x400a809b in FT_Done_FreeType () from /usr/lib/libfreetype.so.6 (gdb) bt #0 0x400a809b in FT_Done_FreeType () from /usr/lib/libfreetype.so.6 #1 0x080b5500 in done_freetype () at font_load_ft.c:1104 #2 0x0808583b in main (argc=2, argv=0xbffe7244) at mplayer.c:3387 mplayer `perl -e 'print "A"x9999'` is OK *With main-cvs: mplayer `perl -e 'print "A"x99999'` segfaults (gdb) bt #0 0x0809e647 in m_config_pop (config=0x41414141) at m_config.c:99 #1 0x080923c9 in play_tree_iter_step (iter=0x84297a8, d=1, with_nodes=0) at playtree.c:558 #2 0x0808717c in main (argc=2, argv=0xbffe7244) at mplayer.c:3457 mplayer `perl -e 'print "A"x9999'` segfaults #0 free_str_list (dst=0x8421a30) at m_option.c:396 396 for(i = 0 ; d[i] != NULL ; i++) (gdb) bt #0 free_str_list (dst=0x8421a30) at m_option.c:396 #1 0x080a0209 in copy_str_list (opt=0x83162a0, dst=0x8421a30, src=0x8421a30) at m_option.c:574 #2 0x0809e713 in m_config_pop (config=0x84247c0) at m_option.h:236 #3 0x080923c9 in play_tree_iter_step (iter=0x842bec0, d=1, with_nodes=0) at playtree.c:558 #4 0x0808717c in main (argc=2, argv=0xbfffd1d4) at mplayer.c:3457 Best regards, -- Pierre
