[MEncoder-users] Empty generated file with -of mpeg

[Etienne Buira]

Hi.

I have troubles using -of mpeg.

My command line is:
mencoder -o "hm_test_mencoder_dvd_aacmp4_x264.avi" -ss 2:00 -endpos 20 \
-oac faac -faacopts br=64 -of mpeg -mpegopts format=dvd:tsaf -ovc x264 \
-x264encopts \
threads=1:bframes=0:frameref=7:direct_pred=auto:partitions=all:8x8dct:me=umh:subq=7:mixed_refs:trellis=2:crf=21 \
source.ts

I have tried all combinations of "-vf harddup", "-noskip", and "-mc 0"
(used dumbly, because I have read that it could help).

All combinations lead to an empty generated file (strictly 0 byte), and
output is full of "INITV: 0.200, 0.160, fps: 25.000".

If I use format=mpeg1 or mpeg2, the INITV lines are still there, the
produced files are exactly 4096 bytes long, and are not playable at all.

What can I do to correctly encode/mux my extract?

Here is a cleaned output of the above line:

Yes, I know the filename's extension is avi, this is because my set-top
box, for which the file is to be tested, filters filenames by extension,
despite it supports some mpeg containers.
