Cannot playback mpeg-2 encoded video

[EEdcom]

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/vvxuxfzbr...1vFLlMGia?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.
Link: http://media.xiph.org/BBB/BBB-360-png/

Following command was used in converting:

png2yuv -j big_buck_bunny_%05d.png -f 24 -I p -b 13000 -n 200 > result.yuv

Do anybody knows, what am I doing wrong?

The result.yuv seems to be OK, plays well in VLC.
The encoded clip (out.m2v) has 200 frames only it is 200 times the same frame: the first frame from result.yuv.
I don't know enough about the used encoder to help you with that.

Actually, the problem was with the raw .yuv data file. Old mpeg2-encoder didn't support RAW I420 coded video. I solved the problem by converting video stream into the separate .Y .U .V data files (200 in total).

I am interested to know, if somebody can suggest .yuv video format which is also supported by the old mpeg2-encoder..

AFAIR - just copy (concatenate) binary Y+U+V - i use this encoder in 2003 or somewhere around 2003.
Planar should work...
