Comment (by pross):

 @ramitbhalla, you have reported two separate problems here.

 1. '''"Subtitle copying does not work."'''

 wtvenc does not currently support subtitle muxing. The error messages
 could make this clearer (codec type 0x3 is AVMEDIA_TYPE_SUBTITLE).
 Essentially you are asking for an enhancement.

 {{{
 [wtv @ 02d8a780] unknown codec_type (0x3)
 [wtv @ 02d8a780] write stream codec info failed codec_type(0x3)
 [wtv @ 02d8a780] write stream codec failed codec_type(0x3)
 }}}

 2. '''"Attachment metadata copying does not work."'''

 If you exclude the subtitle stream this works. e.g:

 {{{
 ./ffmpeg -i test-wtv.wtv -c copy -map 0:0 -map 0:1 -map 0:2 -map 0:4
 out.wtv
 }}}
