I've updated my photos page to show the improvement in quality. 

Anyone want to do a joint blog article that covers both ffmpeg and ofvideoplayer. 

I would very much like to try my new found knowledge on ofvideoplayer. any chance you can send me the doc on the sound stuff.

Hi all 

Well the video has been playing for more than 20 minutes and no problems, its 2 hour movie, it wil probably play through. 

Here are the changes to my ffplay you got from my svn 

use Frame_x and Frame_y values of 256 
Reduce the audio buffer to 64, probably doesn't matter but the doc says use the smallest resonable buffer 
I must of looked at this code several times and wondered how it worked, well the answer was it did not. 

comment out these lines in QueuePicture 

/* if the frame is not skipped, then display it */ 


//AVPicture tmpPict; 

//avpicture_alloc(&tmpPict, DST_PIX_FMT, FRAME_X, FRAME_Y); 

/* get a pointer on the bitmap */ 

create a global variable 

static AVPicture tmpPict; 

Copy this line to alloc_picture 

Just before calling SDL_PixelFormatEnumToMasks 

avpicture_alloc(&tmpPict, DST_PIX_FMT, FRAME_X, FRAME_Y); 

Now all I need to do is figure out how to overlay som simple controls. And we are set to go
