read and play AVI

I have a problem when playing videos (AVI) on GUI

function aviaxes_OpeningFcn(hObject, eventdata, handles, varargin)
mov = aviread('Shania.avi')
movie(handles.axes1, mov);

??? Error using ==> aviread at 76 Unable to locate decompressor to decompress video stream

Error in ==> aviaxes>aviaxes_OpeningFcn at 54 mov = aviread('Shania.avi')

What happens if you execute aviread('Shania.avi') at the command line?

Which Windows version are you using, and are you running the 32 bit or 64 bit windows?

hi walter

I'm running windows XP2 32 bit

Answer 1

Please see this technical solution

(Note to Windows 64 bit users: most codecs are not available in 64 bit versions, and some common codecs like Indeo5 are not available for Windows 7 at all; however it is reported that R2011b will have a new class that will relieve some of the codec issues.)

I've tried to install the codec pack, but the error still occurs.

??? Error using ==> aviinfo>errorWithFileClose at 609

'RIFF' did not appear as expected.

Error in ==> aviinfo at 92

errorWithFileClose(msgID,msg,fid);

if I use the function implay ('Shania.avi') can run but his voice is not an ad, why? please advice

[Walter Roberson]

It sounds as if you do not have the audio codec used by that AVI. Does aviinfo() give you any information about the codecs of the file?

>> aviinfo('Shania.avi')

ans =

Can you advise a suitable converter AVI with matlab

[Walter Roberson]

That's the MPEG-1 Layer 3 MP3 audio codec, but it appears that it is most often generated by Unix software that produces incorrect audio headers when encoding.

Try the codec at http://www.moviecodec.com/download-audio-codecs/mpeg-1-layer-3-codec-18/
