I have a avi file with streams as follows
Stream 0: Video, MPEG2 video, 480x576, 25fps Stream 1: Audio, MP2, 44100Hz, 192kbps
I am trying to convert the above file into SVCD complaint mpg file. So, I used the following command to convert it.
mencoder -oac copy -ovc copy -of mpeg -mpegopts format=xsvcd -o o.mpg I.avi
The output video now has the following specs
Stream 0: Audio, MP2, 44100Hz, 192kbps Stream 1: Video, MPEG2 video, 480x576, 50fps
The output video runs the audio at normal pace but the video is played at accelerated pace. The original video ends in 35mins 27s but the output video ends in 25mins 43s.
What am I doing wrong?
Also I do not understand how did the fps change, after all I simply copied the video to the new container.
