Onderwerp: [Libav-user] Buffered encoded images not saved

Hi all,

I have an issue with the first 12 images not being saved to file. I have 
attached my code ( the relevant ones ) in this email, I have also attached a 
log file to show that the first 12 images aren't written to the file that is 
generated. The frame rate is 24 fps and the recording is 5 sec, so there should 
be 120 frames written to the file. This can be seen in the 4th column. The 
lines in the log files are as follows :

[cpp filename] : image num [ unique num from camera]  [temp image num for 
recording seq] [time in ms]

The image class is actually a simple wrapper around  OpenCV's mat class with 
some addition members. The output file is around 10 MB and when I open it in 
VLC it doesn't run for 5 seconds but more like 1 - 2 seconds. Can anyone 
explain the files not written and the duration not being 5 secs. As you can see 
I have tried with  "av_interleaved_write_frame"  but that didn't help
