Comment:

 With the sample from ticket #3224 in http://samples.ffmpeg.org/ffmpeg-
 bugs/trac/ticket3224/:
 The following work as expected:
 {{{
 $ ffmpeg -i HD_subs_1080_win_33a_cut3.ts -filter_complex [0:0][0:3]overlay
 -an -qscale 2 -t 3 out1.avi
 }}}
 {{{
 $ ffmpeg -i HD_subs_1080_win_33a_cut3.ts -filter_complex [0:v][0:s]overlay
 -an -qscale 2 -t 3 out2.avi
 }}}
 For the following command line, a video stream instead of a subtitle
 stream is chosen:
 {{{
 $ ffmpeg -i HD_subs_1080_win_33a_cut3.ts -filter_complex
 [0:p:37060:v][0:p:37060:s]overlay -an -qscale 2 -t 3 out3.avi
