Oh, another thing: It depends on how these VOBs were ripped. In most cases, ffmpeg won't we able to handle them as a bundle, with concat.
* One Video * 4 audio streams * Many subtitles * Chapters I want to re-encode one of the audio streams (the first one) and keep everything else as-of (copy). Is it possible to do that in one command-line in ffmpeg? So far my best 2 guesses don't work:
Map – FFmpeg, This is useful if you want to mux only and avoid encoding. Choose all streams. Single input: ffmpeg -i input.avi -map 0 output.mkv. Multiple inputs: The tee pseudo-muxer was added to ffmpeg on 2013-02-03, and allows you to duplicate the output to multiple files with a single instance of ffmpeg. The example below outputs an MKV file, and a UDP stream.
Creating multiple outputs – FFmpeg, One with a single video stream and another with one audio stream and one subtitle stream. How can I merge these two files together? I tried multiple input video streams. I'm trying to transcode an m2ts file that contains three video streams, and I don't seem to be able to tell ffmpeg to use the first stream: /usr/local/bin/ffmpeg -i
ffmpeg Map with multiple input files, When there are multiple input files, ffmpeg tries to keep them synchronized by tracking lowest timestamp on any active input stream. Encoded packets are then When there are multiple input files, ffmpeg tries to keep them synchronized by tracking lowest timestamp on any active input stream. Encoded packets are then passed to the decoder (unless streamcopy is selected for the stream, see further for a description).
Save DATA stream, Use ffmpeg -i URL -map 0:d -c copy -copy_unknown -f data data.bin. 3.2 Stream copy. Stream copy is a mode selected by supplying the copy parameter to the -codec option. It makes ffmpeg omit the decoding and encoding step for the specified stream, so it does only demuxing and muxing. It is useful for changing the container format or modifying container-level metadata.
Map – FFmpeg, Stream specifiers include video, audio, subtitles, data, attachments. Most of the examples below ffmpeg -i input.avi -map 0 -c copy output.mkv So as you can see, it's a very unconventional data stream. I don't need it to be parsed or reencoded or anythig, just to copy "as is". Btw, I just tried and ffmpeg also won't put the streams into mkv!

The only data you're preventing with this would be subtitles, metadata, etc from what I can see. – Rogue Mar 8 '18 at 15:48
Map – FFmpeg, Choose all streams; Video streams only; Audio streams only; A specific video stream only ffmpeg -i input.avi -map 0 -c copy output.mkv To checksum only the video track. Add the -map option to only choose the video stream(s). Using -map disables the default stream selection behavior and allows you to manually choose the streams you want. Example: Decoded. The video and/or audio will be fully decoded. This can be slow. ffmpeg -i input.mp4 -map 0:v -f md5 - Example: Stream copied
ffmpeg Documentation, Use ffmpeg -i in.mkv -vf scale=hd720 -map 0 -c copy -c:v libx265 out.mkv. To encode audio as well, ffmpeg -i in.mkv -vf scale=hd720 -map 0 -c copy -c:v libx265 In the question you linked, the string is -c copy, which means set all codec operations to copy i.e. video, audio, subtitles, data and attachments, if any. -c is short for -codec. If you set -c:v copy, it means to copy any video streams being processed. Same holds for -c:a or -c:s or -c:d. Of course, FFmpeg must support muxing the targeted
