I have an AVI file which format is 720:540 (4:3).
When I play this file on my Sony BRAVIA with PS3Media Server 1.72.0 it gets stretched to 16:9 without black bars on both sides... so stretched wrongly.

I tried a little bit around with mencoder expanding/scaling and found out, that When I produce a MPEG2 file with the following switches, the MPEG is shown perfectly on my TV:

Code: Select all
/usr/local/bin/mencoder -ss 0 "test.avi" -msglevel statusline=2 -oac lavc -of mpeg -mpegopts format=mpeg2:muxrate=500000 -ovc lavc -channels 6 -lavdopts debug=0:threads=2 -lavcopts autoaspect=1:vcodec=mpeg2video:acodec=ac3:abitrate=448:threads=2:keyint=5:vqscale=1:vqmin=2 -subdelay 20000 -ofps 24000/1001 -lavdopts fast -mc 0.1 -vf expand=aspect=16/9,scale=-2:240 -af lavcresample=48000 -srate 48000 -o - -really-quiet -msglevel statusline=2 > test.mpeg

When I play test.mpeg on my TV it is perfect!

I now used codec_spec_script to achive the same:
Code: Select all
DEBUG 2013-02-02 17:53:39.890 [mencoder-18] Starting mencoder -ss 0 "test.avi" -msglevel statusline=2 -oac lavc -of mpeg -mpegopts format=mpeg2:muxrate=500000:vbuf_size=1194:abuf_size=64 -ovc lavc -channels 6 -lavdopts debug=0:threads=2 -lavcopts autoaspect=1:vcodec=mpeg2video:acodec=ac3:abitrate=448:threads=2:keyint=5:vqscale=1:vqmin=2:vrc_maxrate=54000:vrc_buf_size=1835 -subdelay 20000 -ofps 25 -lavdopts fast -mc 0.1 -vf expand=aspect=16/9,scale=-2:240 -af lavcresample=48000 -srate 48000 -o - -really-quiet -msglevel statusline=2

But now I have black bars on the side AND on the top and the video is stretched to 16:9 again but with black bars all around it... this drives me crazy. Why is the MPEG file shown correctly but the on-the-fly-transcoded AVI file not?

-srate 48000 -o - -really-quiet

What is it? Weird that MEncoder didn't generated error.
How you played test.mpeg file which works? You copied it to USB stick and played it directly on TV or streamed it as is directly from PMS?
