Bug#859623: handbrake-cli: Encoding a DVD with Closed Captions (Text [CC]) stream in mkv format fails

[E Harris]

Package: handbrake-cli
Version: 1.0.3+ds1-1
Severity: important

When attempting to encode a video from a DVD image using a mkv output format
and also containing a Closed Captioning stream fails to mux properly and 
produces errors.  A subtitle track of the same type as stream 3 from the 
following seems to be required to produce the error (list is from the 
handbrake-cli log):

  + subtitle tracks:
    + 1, English (iso639-2: eng) (Bitmap)(VOBSUB)
    + 2, Francais (Forced Caption) (iso639-2: fra) (Bitmap)(VOBSUB)
    + 3, Closed Captions (iso639-2: eng) (Text)(CC)

During the encode, an error similar to the following is produced in the log:

[matroska @ 0x7ff3f9596780] Subtitle codec 94212 is not supported.

Following that error which is only produced once, thousands of error messages
similar to the following are produced:

ERROR: avformatMux: track 2, av_interleaved_write_frame failed with error 'Function not implemented'
ERROR: avformatMux: track 0, av_interleaved_write_frame failed with error 'Function not implemented'
ERROR: avformatMux: track 0, av_interleaved_write_frame failed with error 'Function not implemented'
ERROR: Last error repeated 2 times
ERROR: avformatMux: track 1, av_interleaved_write_frame failed with error 'Function not implemented'
ERROR: avformatMux: track 1, av_interleaved_write_frame failed with error 'Function not implemented'

Doing the encode using exactly the same options except using '-f mp4' output 
format instead of '-f mkv' seems to work fine.  Likewise, leaving the Closed
Captions (Text [CC]) subtitle track out of the encode also seems to work 
properly.

An example command line that produces the problem with this subtitle stream
type is as follows:

HandBrakeCLI --title 1 --quality 22 -f mkv -e x264 --audio 1 --aencoder ca_aac --ab 160 --subtitle 1,3 --input source_dvd/ --output ./output.mkv

In searching the forums for a similar error, the only reference I found was 
this link which references a prior version of handbrake and which suggests 
the problem might be due to a libavformat version mismatch with the binary:

https://forum.handbrake.fr/viewtopic.php?f=10&t=32082

I haven't yet been able to get all the dependencies to get handbrake to
build from source on my system, so I don't know if the "fix" suggested in 
that link works in this case.
