ffmpeg

I am using C# and ffmpeg.

In this scenario I have 279 individual jpegs and i have used ffmpeg to create a AVI file from these images on my client.

CMD Line:

 -f image2 -r 10 -i "C:\000EC902F17F\img%05d.jpg"  -s 352x288  -y "C:\1\test.avi"

I then upload to my server.

CMD Line:

-i c:\1\1.avi c:\1\img-%05d.jpg

I then extract jpegs from the AVI file. I get 265 jpegs back.

Obviously ffmpeg is dropping these frames (most probable) when the avi is 1st created. Is there a way to 'force' to encode using ALL the images I have?

Thanks.

PS I did not specify any command line option other than the size of the video output. As far as I am aware if none are specified then ffmpeg automatically chooses the best ones?

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language.
