---Notes from uncommon audio codecs list--- (This will get refined and moved into the main wiki shortly.) --How to read-- the audio codec as reported in the uncommon_audio_codec.txt is the folder name. If it says all fine, it means all samples (up to 5) played fine in FFplay. If FFmpeg doesn't show the same codec tag, I've included that as well. If there was an issue (audio, or in some cases video) I noted that as well. audio samples: 0x0003- all fine, pcm_f32le 0x0004- link is dead 0x0005- play fine, nellymoser 0x0006- plays fine, nellymoser 0x0032- msgsm, not playable by ffplay. 0x0038 not playable- Natural MicroSystems VBXADPCM codec 0x0055 -now shows as mp3 audio, plays fine 0x0057- AMR-NB (should be playable in latest svn) 0x0074- VoxWare, tries to use voxmvdec.ax 0x00ff- aac audio, fine 0x0111- doesn't play, vivo video- Vivo G.723/Siren Audio Codec 0x0112- doesn't play, vivo video- Vivo G.723/Siren Audio Codec 0x0163- doesn't play, Windows Media Audio Lossless V9 0x0215- doesn't play- Ulead DV ACM 0x0216- doesn't play- Ulead DV ACM 0x0402- doesn't play- Indeo Audio 0x1100736d- adpcm_ima wav 0x1104- doesn't play- Lernout & Hauspie CELP and SBC codecs 0x4143- plays fine now, stereo AAC 0x414c- empty folder - possibly lead audio aac/vorbis/amr ? ~~- unlikely: TwoCC says 0x434C LEAD Speech 0x564C LEAD Vorbis 0x5000736d- mp2, plays fine 0x55005354- doesn't play, video broken (wmv1), gnrc data. the text version of the tag is: U ST 0x0674f- doesn't play- is actually Vorbis- must be forced (ffplay can handle it w/ -f ogg)- according to TwoCC, mode 1 Ogg Vorbis 0x6750- doesn't play- is mode 2 Ogg Vorbis (can be played with ffplay -f ogg) 0x6751- doesn't play- labelled as mode 3 Ogg Vorbis- can't be played 0x6771- doesn't play- TwoCC says Ogg Vorbis mode 3+ 0x706d- says AAC, plays, but playback not perfect: [aac @ 0x88ccfa0]Predictor bit set but LTP is not implemented. Update your FFmpeg version to the newest one from SVN. If the problem still occurs, it means that your file has a feature which has not been implemented. If you want to help, upload a sample of this file to ftp://upload.ffmpeg.org/MPlayer/incoming/ and contact the ffmpeg-devel mailing list. ut3_for_redpax_with_love.avi, ikiwiki_swarm.avi play fine. 0x7a21- doesn't play- 0x7A21 GSM-AMR (CBR, no SID) 0x7a22- doesn't play- 0x7A22 GSM-AMR (VBR, including SID) 0xfffc- doesn't play, vdowave audio. works in mplayer. 0xfffe- themes.avi does- picked up as pcm_f32le adpcm_ct: all play adpcm_ima_dk3- doesn't play. Loud static plays for 5 seconds, then nothing. The TwoCC says MS GSM 723.1, but I can't get it to play. adpcm_swf- all play atrc- 050913.ram says unsupported video codec (rv20) but plays other files have rv20 messages as well dca- audio track 6 shows as 0x0000- should be 0162- wma3 drms- audio most likely DRM'd newYearsSmall.mov- 1st track same as above, crashed ffplay; 2nd track doesn't play, no messages fl32- plays fine fl64- plays fine imc- rx620(new).avi plays, but [imc @ 0x8921330]Read coefficients failed sq= 0B and sounds drops out mace3- plays fine mp1- plays fine. pcm_s24le: plays fine pcm_s32be- plays fine pcm_s32le- plays fine pcm_u16le- empty folder qclq- doesn't play qdmc- doesn't play, QDesign Music 1 iCantHelpIt.mov- mov,mp4,m4a,3gp,3g2,mj2 @ 0x88dcd70]stream 0, error opening file /bugs life.mov: No such file or directory milesaway.mov- apparently DSLV is the Quicktime cross-fade effect. The other two tracks are MJPG. real288- all play sawb- amr_wb?

The hexcodes ( 33564D57 & 33414D57 spell out WMV3 & WMA3 backwards. wmav1- plays fine xovs- no audio or video
- i think xovs is Xiph Ogg VorbiS, the video track of that file is XiTh (Xiph Theora). --Compn 11:26, 20 December 2008 (EST)
- 0xfffe- Loko-Passe_de_Pedros-Nantes_vs_Psg-1994.mpg doesn't play- clip has this metadata:
MEncoder 1.0pre6-3.3.5- look for current codec pack from then- hopefully the audio codec is there
Revision 14844 - (view) (download) (annotate) - [select for diffs] Modified Sun Feb 27 18:11:17 2005 UTC (3 years, 9 months ago) by rfelker File length: 50850 byte(s) Diff to previous 14842 Fix the ogg fourcc nightmare!!! The problem: once upon a time, windows idiots decided to try to store vorbis-in-ogg-in-avi. Of course this failed miserably, but they used the audio format tag 0xfffe for "extended" to do this. Later someone working on MPlayer somehow decided 0xfffe was the format for vorbis, which is nonsense, and now that's conflicting with real wav files with extended audio format. This patch changes demux_ogg (and mkv) to use sane fourcc's for vorbis and theora and gets rid of the 0xfffe nonsense so hopefully wav files with extended audio will work now. If there are problems, we'll have to find workarounds...and drive an 18-wheeler full of cola thru the house of whoever wrote this 0xfffe nonsense in MPlayer to begin with...
