Read here: https://ffmpeg.org/ffmpeg.html#Automatic-stream-selection "In the absence of any map options for a particular output file, ffmpeg inspects the output format to check which type of streams can be included in it, viz. video, audio and/or subtitles. For each acceptable stream type, ffmpeg will pick one stream, when available, from among all the inputs." So, by default, ffmpeg only selects one of each. You can use "-map 0" to get *all* streams from the input. This is at the risk of also mapping e.g. data streams, which the output format may not support. You would surpress them with "-dn". Otherwise, you can map each stream explicitly: "-map 0:a:0 -map 0:a:1 ..." > Also there should be 13 subtitle streams in this video, but I don't find > them here. In VOBs, subtitles tend to appear later in the files. Use large values for "-probesize" and "-analyzeduration" for seeing them (not only when probing, but also when converting). OTOH, your ffmpeg output doesn't report them appearing later, which it should, if it were to find them. So I'm not sure they're there.
