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 : </div>

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</div>
