I guess there is something messed up with my VLC cos when I playback the video it only shows a small portion of the video. For me Quicktime says the video is 640*480 and VLC says 320*240 (The camera is set to 640*480).Video is 320x240 according to Mediainfo, Quicktime and VLC.

Tried doing that, still the same.Have you tried disabling Overlay video output from VLC?
So are you saying this is a bug in the Sanyo MP4 format and won't/can't be fixed in VLC? I'd prefer not to install Quicktime since it continually reinserts itself in the startup sequence.IIRC there are two ways to store video dimension with MP4. One is to store it to MP4 container, another is to put it inside videodata. Container seems to give 320x240 and video stream 640x480. This can be fixed by remuxing the file with yamb+mp4box.
technically it isn't a bug. It is a feature. But most players don't support it properly.So are you saying this is a bug in the Sanyo MP4 format

Maybe but the point is that even QuickTime doesn't do that. It changes the display resolution, yes, but it doesn't crop the video so you can see the whole image which I believe is the expected behaviour.The proper way is to crop the file because the container says that must be done.
Good point. Maybe I should dive into MP4 specs and check it out.Maybe but the point is that even QuickTime doesn't do that. It changes the display resolution, yes, but it doesn't crop the video so you can see the whole image which I believe is the expected behaviour.
Code: Select all
/* Support for cropping (eg. in H263 files) */
p_track->fmt.video.i_visible_width = p_track->fmt.video.i_width;
p_track->fmt.video.i_visible_height = p_track->fmt.video.i_height;
Code: Select all
sudo apt-get install gpac
Code: Select all
find . -name *.MP4 -exec MP4Box -add {} -new {} \;
