AVIREAD unable to locate decompressor when H264 codec is present
显示 更早的评论
Old file ran on R2009A/WIN 32 will not run R2009A/ WIN64 using 'AVS Video Remaker' converted file to H.246. Using video = uigetfile ('*.avi') and then info = aviinfo(video) info.VideoCompresion = H264
Using GSpot I confirm that the H264 codec is present.
However using aviread(video) I get error Unable to locate decompressor. I can display the file on several other programs including 'Windows Media Player'
What is the problem? How do I solve it. PS I have read all of the threads posted on this issue.

It may be the case the H.264 decoder present is a 32 bit version and not 64 bit one. Windows Media Player (and many other applications) on win64 is a 32 bit application and hence is able to play it fine.

H.264 was not supported until R2011b (I think it was.)

Until R2011b you have to use a two-stage process, as best I have been able to puzzle out. One of the stages consists of running a Windows program that can understand h.264, and the second stage consists of transferring the images from the Windows program to MATLAB.
The archived discussions are a bit murky, and it could be that what I am describing only applies to _streaming_ video rather than video already available in a stored file.

Hi Richard,
How do you convert h.264 to wmv?
Thanks,
Avner
