Add support for -dn (to disable data streams)

[dericed]

Feature request for a method to suppress data streams, similar to -vn, -an, and -sn.

[dericed]

oops, I double-clicked and made two tickets. See  https://ffmpeg.org/trac/ffmpeg/ticket/648

Please add a failing command line (that would profit from -dn) and complete, uncut console output.

Here's a failing command line that would profit. When I use -f framemd5 the default is that only the first video and first audio track are used in framemd5. To include all the tracks in the framemd5 output, I can use -map 0 to do this (easier than adding lots of -newaudio and -newvideo). But data tracks don't work in -f framemd5.

ffmpeg -i example.mov -map 0 -f framemd5 -

Seems stream 0 codec frame rate differs from container frame rate: 30000.00 (30000/1) -> 29.97 (30000/1001)

Data stream encoding not supported yet (only streamcopy)

[dericed]

Ah. I used "-map 0 -map -0:d:" and the -map -0:d acted as -dn would. I thought it would be contradictory to say map all plus say don't map data streams, but this worked. wish closed.

[cehoyos]

Could you test attached (completely untested) - with and without -codec copy?

Patch applied.
