Hello all,
I have difficulties, when I am trying to playback mpeg-2 encoded video. I am able to see only first frame of encoded video. Video size is 5.2MB, so there sould be more than one frame. Am I using wrong video encoder parameters (wrong .PAR file)? Or maybe something is wrong with uncompressed .YUV data stream? I am purposely using original (almost 20 years old) MPEG2 encoder, because I am diving into MPEG-2 Part2 standard.
Resulting output video and statics file can be found here:
https://www.dropbox.com/sh/vvxuxfzbrz7pkmp/AABR43WIL4XStRnz1vFLlMGia?dl=0
The produced video should follow the PAL system standard and be displayed on computer screen.
My display specification is following:
xrandr
Screen 0: minimum 320 x 200, current 1680 x 1050, maximum 8192 x 8192
VGA-0 disconnected (normal left inverted right x axis y axis)
LVDS connected primary 1680x1050+0+0 (normal left inverted right x axis y axis) 365mm x 228mm
1680x1050 58.79*+
1400x1050 59.98
1280x1024 59.89
...
S-video disconnected (normal left inverted right x axis y axis)
DVI-0 disconnected (normal left inverted right x axis y axis)
Here is the setup which I used in the experimets:
Source video: uncompressed .YUV file, including in total 200 "Big Buck Bunny" .png images.
