BTW, I just discovered a funny thing... ffmpeg has two "-loop"
options :)
One defined in ffmpeg.c, the other is an AVOption from

As a result, it is currently impossible to enable the in-loop deblocking
filter from ffmpeg command line... I did not notice this yesterday
because I was testing by using my own c test program, and not ffmpeg...

The attached patch renames the "ffmpeg.c -loop option" so that the
libavcodec/utils.c one can be used. With this patch, "-loop 1" works.

To Michael: is the patch ok? Or should I write the patch the other way
around, by renaming the AVOption's "-loop"?

Copy this in your signature, if you think it is important:
