Automated encoding using ffmpeg and libx264

**jokenjp** · January 8th, 2014

I have a python script that will encode using below command

Code:

ffmpeg -i a.mkv -tune animation -keyint_min 12 -sc_threshold 45 -bf 8 -b_strategy 2 -refs 10 -qmin 10 -qmax 51 -qcomp 0.6 -direct-pred auto -me_range 24 -me_method umh -subq 9 -trellis 2 -vcodec libx264 -crf 23.0 output.mkv

The output.mkv successfully generated but without correct fonts from the original video. How do I output the video the same with original video's font?

I don't know the answer to your question per se but in such cases concerning the 'ffmpeg' command it's useful to post -
What release of Ubuntu do you have
What version of ffmpeg

Also the complete ffmpeg console output is required information.
I don't quite understand what the issue is.

hi i use latest ffmpeg from github and compile it successfully

and encoding does not have problems, the output.mkv plays well it just that the font changes to Arial which the original video uses different font. Any idea why ffmpeg does not use the original video's font?

Please show your complete ffmpeg console output. Providing a sample input file will also be very useful. We need enough information from you so anyone can attempt to duplicate the issue.

below is the ffmpeg output
please have a look, it seems that it can't extract font and uses Arial instead, this changes the output video to have different font from original video

Why are you re-encoding in the first place? It's not like you're changing formats.

I'm not sure why none of the attachments appear to be included. Default stream selection should include one stream per stream type. You can try adding "-map 0:t -codec:t copy", but I'm unsure if it will work as expected since I do not have a sample file.

Why are you not using an encoding preset? The preset will include most of your options you manually added. The "slower" or "veryslow" presets will be most like your options:

Code:

ffmpeg -i input -codec:v libx264 -crf 23 -preset slower -tune animation -codec:a copy -map 0:t -codec:t copy output.mkv

hi

I have included preset to veryslow but still it is not copying the font files, and when I use your syntax, it does not able to generate output and show below
I am encoding it to make it smaller size

Code:
