I have some MKV files that I would like to copy to my PS3, so I have to convert them.
Someone told me the easiest way without losing quality would be with ffmpeg.
However, I want them to have subtitles and when I use:
ffmpeg -i in.mkv -vcodec copy -acodec copy out.mp4
…they don't appear in my PS3.
Furthermore, some files have DTS audio - how can I convert them so I have audio in my PS3?
Is it possible to do everything with ffmpeg?
And one of my files, when I converted it, it ran too slowly in my PS3 as if it was in slow motion - Can I do anything to change that? Also, the subtitles are "inside" the MKV file. Do I need to do something different?
Answer
-acodec copy implies that you maintain the audio codec. Also, if your PS3 cannot keep up with the video codec, I would recommend converting everything.
The loss of quality in the conversion is usually negligible for video playback.
Try this:
ffmpeg -i in.mkv -c:v libx264 -c:a libvo_aacenc -b:v 35M -b:a 224k out.mp4
NOTE this values are quite high to start, so you could try lowering them if the file size is too much: 35M for 1080p, 15M for 720p, 5M for 480p
