[FFmpeg-devel] [PATCH 2/2] movtextenc.c: Support for Bold, Italic and Underlined styles

The output produced here was actually different from the expected. Hence
the test failed. I produced ASS file for both the original file and the
encoded file. The ass file produced from the encoded mp4 file seemed to be
dropping all text after \N
After a lot of digging, I found out that while appending '\n' into the
buffer in encoding, it is to be considered as a single character and not 2.
Making this change in movtextenc.c solved the issue and now I have matching
ASS outputs for both the files.
However, the test still fails even though I have exact same ASS files.
PS - there is no style information associated here as far as I can see.
Please correct me if I'm going wrong here.

Likely this is because we're now carrying over formatting that we were
dropping before. Niklesh, you should look at the fate sample file and
verify this is what we should expect.
