pnm port and stream problem.
by compn 08 Jun '05

08 Jun '05

pnm can be accessed on port 80 as well as 7070. pnm://www.darrelbowen.com/videos/commercials256.rm vs pnm://www.darrelbowen.com:80/videos/commercials256.rm it still doesent work with mplayer, but it does connect :) i've also heard of an evil way if pnm:// fails on port 7070 you can sometimes use rtsp:// on port 7070 to get it working. so in theory pnm:// 7070 default, if timeout, pnm 80, if timeout, rtsp 7070. comments?

FAAD problem on AMD64: no sound
by Daniel Hottinger 06 Apr '05

06 Apr '05

Hi, Short version: Distribution: Debian/SID, pure64 port for amd64 MPlayer-CVS : 2005-03-25, ~10:00am Problem : no sound when internal FAAD2 is used Sample data : ftp://mplayerhq.hu/MPlayer/incoming/zx.eva.renewal.01.divx511_first_5mb_amd64.mkv MPlayer -v : zx.eva.renewal.01.divx511_first_5mb_amd64.txt Bugzilla : nothing found Long version: There seems to be a problem with the internal libfaad on amd64. The sample file has two audio streams: AAC and Ogg/Vorbis. The playback of the 6-channel AAC stream [faad] is completely silent (but the volume is normal at 50%) while the playback of the 2-channel Ogg/Vorbis stream [libvorbis] works. Surround ist not the problem since wav-files with 6 channels work. Also, on my laptop (Pentium III, x86) faad works nicely with the same file and the /same/ relevant output: --------------------------- Opening audio decoder: [faad] AAC (MPEG2/4 Advanced Audio Coding) dec_audio: Allocating 4608 bytes for input buffer. dec_audio: Allocating 49152 + 65536 = 114688 bytes for output buffer. FAAD: Decoder init done (0Bytes)! FAAD: Negotiated samplerate: 44100Hz channels: 6 FAAD: compressed input bitrate missing, assuming 128kbit/s! AUDIO: 44100 Hz, 6 ch, s16le, 128.0 kbit/3.02% (ratio: 16000->529200) Selected audio codec: [faad] afm:faad (FAAD AAC (MPEG2/MPEG4 Audio) decoder) --------------------------- Interesting is that the Debian vlc (0.8.1) also uses FAAD and can play video and the AAC sound. I've tried all 26 files of Evangelion and also some others with 2-channel AAC audio. Same Result. I am on the list and would like to help to track this bug down.

MPlayer does not escape symbols in rtsp URLs (possible bug)
by marlon＠freemail.gr 07 Mar '05

07 Mar '05

Hello. Let's have an rtsp stream: rtsp://nice.site.com/file The stream requires username and password so the cmd line becomes: mplayer rtsp://username:password@nice.site.com/file Now if the password includes the "@" symbol ("pass@word") the cmd line becomes: mplayer rtsp://username:pass@word@nice.site.com/file Bue that causes error due to the fact that the password is parsed as "pass" and not "pass@word". Apart from that, there is a "could not resolve" error as the "nice.site.com" is mislooked as "word(a)nice.site.com". Escaping the first "@" with "%40" or "\@" doesn't work either. Regards.

dvr ms codec (lol!)
by compn 06 Mar '05

06 Mar '05

ok, so i see some requests for this codec, on XBMC lists and on -users i finally got a sample to check out... its an asf container with mpeg2 video. libmpeg2 kind of decodes the sample i have, but with some errors... ffmpeg wont decode it for me. add format 0x20525644 under videocodec mpeg2 in codecs.conf mplayerhq.hu/MPlayer/incoming/microsoft-new-way-to-shove-mpeg2-in-asf.dvr-ms good site, lots of ms info from: http://support.microsoft.com/default.aspx?scid=kb;[LN];316992 Microsoft Digital Video Recording (.dvr-ms) In Microsoft Windows XP Media Center Edition, Microsoft introduced the *.dvr-ms file format for storing recorded TV content. Similar to *.asf files, *.dvr- ms file enhancements permit key Personal Video Recorder (PVR) functionality, including time-shifting, live pause, and simultaneous record and playback. Video contained in a *.dvr-ms file is encoded as MPEG-2 video stream, and the audio contained in the *.dvr-ms file is encoded as MPEG-1 Layer II audio stream. To play back unprotected *.dvr-ms files on Windows XP-based computers, you must have the following software and hardware components: � Microsoft Windows XP Service Pack 1 (SP1) or later. � The update that is documented in the following article in the Microsoft Knowledge Base must be installed on the computer: For additional information, click the following article number to view the article in the Microsoft Knowledge Base: 810243 DirectShow playback support for files recorded with Windows XP Media Center Edition � A Windows XP-compatible DVD decoder.

lavc 2-pass ratecontrol bug
by Zoltan Hidvegi 04 Mar '05

04 Mar '05

The problem is that lavc mpeg-4 uses quantization level 31 for more than 10% of the video. I'm not sure if it has anything to do with it, but the source mpeg has some very dark portions (it's the 16th episode of the ABC show Lost). I was also using dd to cut the commercials before encoding, so there are some damaged mpeg2 frames near the cutpoints. Here are the commands I've used for encoding: First pass: mencoder -vfm ffmpeg <hdtv-1080i-mpeg-ts-file> -tsprog 1 -vop hqdn3d=4:3:3,scale=1024:576,harddup,softskip,filmdint=crop=1908:1078:4:0 -oac copy -ovc lavc -lavcopts vcodec=mpeg4:psnr:mbd=2:v4mv:aspect=16/9:vmax_b_frames=1:trell:cbp:cmp=2:precmp=2:subcmp=2:vb_qoffset=0.5:vpass=1:vdpart:vpsize=1000:vqcomp=0.75:lmin=4:lmax=4 -force-avi-aspect 16/9 -sws 1 -fps 29.97 -ofps 23.976 Second pass: mencoder -vfm ffmpeg <hdtv-1080i-mpeg-ts-file> -tsprog 1 -vop hqdn3d=4:3:3,scale=1024:576,harddup,softskip,filmdint=crop=1908:1078:4:0 -oac copy -ovc lavc -lavcopts vcodec=mpeg4:psnr:mbd=2:v4mv:aspect=16/9:vmax_b_frames=1:trell:cbp:cmp=2:precmp=2:subcmp=2:vb_qoffset=0.5:vpass=3:vqcomp=0.75:vbitrate=1000:vdpart:vpsize=1000 -force-avi-aspect 16/9 -sws 1 -fps 29.97 -ofps 23.976 The 2 passes take more than 4.5 hours, so it's not easy to experiment with changes. I've posted about a similar bug before, see http://mplayerhq.hu/pipermail/mplayer-advusers/2005-February/001093.html but I got no reply. This problem happens very often in 3-pass mode, but this is the first time I see this in 2-pass mode. I've uploaded badquant.tar.bz2 to mplayerhq incoming which contains the passlog files from both passes (pass1.log, pass2.log), the psnr file (pass2.psnr) and the output of mencoder in the second pass (pass2.out). All this was done with the Feb 28 CVS of mplayer and libavcodec. Thanks, Zoli

Re: rtsp fallback to http and different formats over rtsp?

Running "openRTSP" on the "rtsp://" URL above reveals that the stream uses three 'experimental' RTP payload formats: "audio/X-ASF-PF", "application/X-WMS-RTX", "video/X-ASF-PF". However, I don't know anything about these payload formats; they seem to be Microsoft-specific crap. Ross Finlayson LIVE.COM <http://www.live.com/>
