New submission from blindbunny <[email protected]>:
I am trying to convert a Bluray title with ffmpeg. On this particular file,
ffmpeg automatically adds a scaling filter, which I cannot get rid of, to scale
the 1080p video stream down to 720x480. Interestingly, the file contains further
video streams that have frame dimensions of 720x480 so maybe that plays a role.
This issue occurs with a current SVN checkout of ffmpeg from 2010-08-09.
On the following command, note that there is no scaling filter specified
explicitely but the ffmpeg output clearly shows that ffmpeg applies a scaling
filter:
#> ffmpeg -i /tmp/misscaling-video.m2ts -vf crop=0:0:1920:1080 -vcodec libx264
-f h264 /tmp/output.h264 -map 0.0

Error opening filters!
The issue remains when I use exlicit stream mapping by appending '-map 0.0' to
the command line.
I'll upload the input file misscaling-video.m2ts to
upload.ffmpeg.org/MPlayer/incoming/issue<issue nr>/
