input Matrox avi problem #64

Description

@GoogleCodeExporter
Is not possible convert completely a video file format MATROX, because the 
output file duration is smaller than the input file.

I noticed that in the input description the duration of the video is not the 
real one

In the test below I have converted video and audio with the same duration.


Command line:

ffmbc -i Matrox_Mpeg2_iframe_15Mbs.avi -i pcm_s16le_1536kbs.wav -target imx50 
IMX50_From_Matrox.mxf

Output:
