I'm new to ffmpeg (windows), and need some help. I want to convert my MKVs to MP4 with as little loss in quality as possible. The MKVs are made with makemkv, and contains among others DTS soundtrack. They are lossless. The reason I want to convert, is that I plan on stream it to iPads and apple tv. iPads don't support DTS and MKVs. The MKVs are both DVDs and BR. The MKVs contain video, soundtracks and subtiteles.
I have tried this, but get no sound due to DTS soundtrack: ffmpeg -i input.mkv -c:v copy -c:a copy output.mp4
Can anybody help me?
What codecs should I use? MP4 is the best for apple?
