lavc-Options for *BEST* quality?
by Sven Over 14 Feb '03

14 Feb '03

Hi, all. I"m affraid I'm not up-to-date with all that lavc-options. (E.g. what is qpel?) So, my question to the experts in this list: what are the options to use with lavc if I want to get highest possible quality for a given bitrate. CPU-time (almost) does not matter. Thanks in advance.

>Not exactly. The start is mjpeg, then after a small amount of time it's sorenson (iirc). Hence the >audio desync if you just skip the mjpeg. Well, it is my time to also say 'not exactly' :) The audio desync comes from the movie having two (2) audio tracks. mplayer plays both at once, and not in sequence as the windows player does. there must be a flag somewhere in the movie that explaing this behaviour. >I'm not convinced the current mplayer structure would take enjoy changing codecs on the fly much. Yes, Arpi has mentioned that, but it works nevertheless...

strange tv input behavior
by Marcin Bukat 14 Feb '03

14 Feb '03

Hello! I found strange tv input throught AverMedia capture card behavior. If I connect tv antenna into card, I can watch or recodrd signal without major problems. Yesterday I wanted to copy VHS record using my old VHS player. I connected antenna output from player to antenna input in capture card and selected channel mentioned in player's manual. I've got sound but no video (first green, second blue screen). The line I used to play was (similar to thouse I use to watch tv): mplayer -tv on:driver=v4l:channel=37:width=640:height=480 -vo xv I discoverd also that I have continouse streem of such messages in syslog: Feb 13 20:13:57 PCB kernel: bttv0: aiee: error loops Feb 13 20:13:57 PCB kernel: bttv0: resetting chip Feb 13 20:13:57 PCB kernel: bttv0: PLL: 28636363 => 35468950 ... ok Feb 13 20:13:57 PCB kernel: bttv0: irq: SCERR risc_count=1f56b074 Feb 13 20:13:57 PCB kernel: bttv0: irq: SCERR risc_count=1f56b054 Feb 13 20:13:57 PCB last message repeated 3 times Any idea? wodz

realmedia, num_of_packets and DATA chunks
by Olivier Galibert 14 Feb '03

14 Feb '03

That format is interestingly crap. In some cases you get: Packet 17737 / 17739 00C8442F: packet v0 len=1015 id=1 pts=461035 rvd=0 flags=0 block: hdr=0x1, len=1143, offset=0, seqnum=2 Packet 17738 / 17739 00C84826: packet v0 len= 166 id=1 pts=461035 rvd=0 flags=0 block: hdr=0x81, len=1143, offset=147, seqnum=2 [chunks=1 subseq=2] Packet 17739 / 17739 00C848CC: packet v0 len=1016 id=1 pts=461099 rvd=0 flags=0 block: hdr=0x1, len=1384, offset=0, seqnum=3 Packet 17740 / 17739 00C84CC4: packet v0 len= 406 id=1 pts=461099 rvd=0 flags=0 block: hdr=0x81, len=1384, offset=387, seqnum=3 [chunks=1 subseq=2] Packet 17741 / 17739 00C84E5A: packet v0 len= 570 id=0 pts=461147 rvd=0 flags=0 Packet 17742 / 17739 [...] Which shows you can't trust num_of_packets in the first place. But then you can have: Packet 17686 / 17688 0063DEAC: packet v0 len= 603 id=15 pts=2543091 rvd=0 flags=2 unknown stream id (15) Packet 17687 / 17688 0063E107: packet v0 len= 62 id=15 pts=2543091 rvd=0 flags=2 unknown stream id (15) Packet 17688 / 17688 0063E145: PING, version=17473, len=5441 "PING" means stream_id=33 (I was going on a wrong hypothesis). In fact there is: 0063e140: 80a8 9a0a 0044 4154 4100 211b 8a00 0000 .....DATA.!..... 0063e150: 0022 9800 84fc cf00 0100 f500 0000 0000 .".............. 0063e160: 0000 0003 4488 5771 7e97 c3a6 202c 8d9e ....D.Wq~... ,.. 0063e170: c0b0 f380 1c37 9127 2f9d 48b0 88c5 e62e .....7.'/.H..... 0063e180: 396d f558 74d2 1eb8 095e 9d84 265c 75f2 9m.Xt....^..&\u. i.e., a new DATA chunk. Probably the best way is to try to check for a new tag when the packet version number goes to hell, but the current code very much doesn't like new chunks in the middle of the stream... OG.

To shed even some more light on the problem, this is the movie type reported by the Windows Quicktime player: format: Photo - JPEG, 640 x 272, Millions QDesign Music 2, Stereo, 44.1 Khz, 16 bits QDesign Music 2, Stereo, 44.1 Khz, 16 bits Movie FPS: 23.99 Data Size: 141,2 Mb Data Rate: 260,4 Kb/sec Although this might be irrelevant to us Linux users, it explains why mplayer cannot play this file without the mentioned patch. It is really stupid, it's like they took each frame of the anime, scanned it to JPEG files and cat them to a MOV container...

Mplayer Stream Player
by usenet＠wingert.org 13 Feb '03

13 Feb '03

I want to use MPlayer to stream files off a network server using a lightweight protocol. -slave mode provides me some of the features I want. However, not quite. I basically want mplayer to respond back to me upon receipt of keyboard/mouse input from the user in addition to the -slave command protocol and video stream. eg. There are three active streams between the control program and mplayer. 1) -slave protocol (program to mplayer) 2) userinput protocol (mplayer to program) 3) video/audio stream. stream 2 provides information back to my control program from mplayer. For example when mplayer receives a forward arrow (to skip forward). I would like MPlayer to tell my program via the stream "skip 5". My control program then repositions the video/audio stream. This gives me two advantages : 1) my program doesn't have to re-do all the great input.conf/input work in player and 2) mplayer can still do OSD stuff. Does this make sense? Better yet, has anyone worked on this before I attempt to do it? Thanks

Audio Lag and Index Problem
by Oliver Strutynski 13 Feb '03

13 Feb '03

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I've been using MPlayer as my player of choice for quite a while and am now trying to get into encoding some of my DVDs. I started with the NTSC version of Life is Beatiful and ran into the following problems: I used the following command line: mencoder -dvd 1 -alang en -o test2.avi -oac mp3lame -lameopts vbr=3:vol=8 \ -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=1602:vhq:vqmin=2:keyint=11 \ vlelim=-4:vcelim=9:lumi_mask=0.05:dark_mask=0.01 -vop \ scale=720:336,crop=716:572:2:2 -ofps 23.976 -zoom -aspect 4:3 The bitrate was way too high resulting in a 1.2 Gig file, but that is not the problem. At the end of encoding I got the following output: [...] Pos:7089.6s 169988f (100%) 23fps Trem: 0min 1168mb A-V:-0.029 [1260:116] duplicate 1 frame(s)!!! Pos:7089.7s 169990f (100%) 23fps Trem: 0min 1168mb A-V:-0.023 [1260:116] Writing AVI index... Fixup AVI header... Video stream: 1260.879 kbit/s (157609 bps) size: 1117408800 bytes 7089.713 secs 169990 frames Audio stream: 116.692 kbit/s (14586 bps) size: 103421568 bytes 7090.224 secs Notice the difference between the length of the audio and the video stream. When I checked the resulting AVI file, the first thing that struck me was that MPlayer had to re-generate the index. Shouldn't the index be written to the file even when using one-pass encoding? I also noticed a lag in the audio of around .5 seconds towards the end of the movie. Sound is fine in the beginning, but in the end the lag is noticeable. I would be really grateful for any help. Do I need to get into three-pass encoding to fix this? A am using MEncoder 0.90rc2-2.95.3 on SuSE 8.0 with a 2.4.19 Kernel if that matters. Thanks a lot!

Re: [MPlayer-users] DVD time messes up subtitle

I just can't jump to a later point with the -ss option (not a problem) and the subtitles reset at that point. (real problem) BTW, I played the DVD on the standalone player and it didn't do that reset so it probably really *is* a mplayer problem. > > Originally I created SVCD subtitles but mplayer can't display them > > (yet?). > How did you create them?

I searched for some > information on that topic, but could not find anything either. So if > you have informations, please share. :) http://www.vcdimager.org/pub/vcdimager/contribs/svcd-subtitles.tar.gz It is nothing more than a hack, long since abandoned and a little buggy but all in all it works. So no, there is no good documentation but apparently enough to create subtitles. First I ripped the DVD subtitles, translated them, turned the translation into graphics with a GIMP script I wrote and another script to adjust the timestamps. Then I used that tool to add them to the SVCD mpegs. My standalone player displays them. Every now and then a line is missing or mixed with another subtitle but not often. It was a lot of work, but I really wanted to make a present for my mother's birthday and at the same time keep the japanese subtitles. But now my parents have their own DVD player that doesn't display SVCD subtitles so I have to hard-encode them.
