It essentially instructs FFmpeg to add the “ m2ts” extension to the original filename of the input file to save the converted file to.Ģ, Batch converting any files to MP4 / M4V / MKV's with preserving all (subtitle / audio) tracksĪlso at MacRumors, I've been asked (post HERE and HERE) to explain how one can easily fix a well-known problem of HandBrake: for input files with more than one audio/subtitle track, the need to manually add every single (with DVD's, the original bitmap VobSub) subtitle and every single audio track to the target, converted MKV and MP4 / M4V files while, say, converting the video track from MPEG-2 to H.264. The second dynamic parameter set by the loop is "$f.m2ts". It's passed two dynamic parameters: first, the input filename itself (as was the case with Project-X), "$f", right after the input flag ( -i). Here, the FFmpeg executable is in the “ Contents/Resources/” directory of the “ Video Container Switcher.app” discussed in the above discussion thread. (Originally published HERE note that you can easily check out the context of the posts I link to by clicking the first “ discussion thread” link in the “ You are viewing a single post from a discussion thread on MacRumors Forums.” title above each post.) An example of invoking FFmpeg for a quick remux (container change) with forcing (see the switch “ -bsf h264_mp4toannexb”) FFmpeg to add a keyframe before each converted H.264 stream to make it 100% compatible with the m2ts container:įor f in *.mkv do Video\ Container\ Switcher.app/Contents/Resources/ffmpeg -i "$f" -acodec copy -vcodec copy -bsf h264_mp4toannexb "$f.m2ts" done The (varying) parameter passed to the java interpreter is in “ "$f"”: it simply passes the just-iterated filename to the java executable.īased on this explanation, it's very easy to generalize this to even supply output filenames to apps that, say, require an explicitly given output filename (the above command only required an input one) to write their output to. ts extension (this is what the “ for f in *.ts do … done” part is for) and for each of them, it executes the middle part of the command, java -jar ProjectX.jar.
Just enter the following at the (OS X or any kind of Unix / Linux) command line to mass-process TS files:įor f in *.ts do java -jar ProjectX.jar "$f" done
MKVTOOLS 2 UPDATE
With the excellent DVB TS recording processor Project-X, I've already shown (see the update at ) you how you can quickly and easily extract the subtitle tracks from several TS files at once. Should you want to mass-convert / mass-process a bunch of files in, say, a directory or of the same type, batch files can be of tremendous help. Some of the video converters (for example, Project-X or FFmpeg) (also) have a command-line interface (CLI). In the article below, I present you them all in an edited, more verbose format.ġ, Using batch files (or looping commands) with command-line applications At MacRumors, I've published a lot of tips on mass converting videos to make one's life much easier when mass-converting several videos at a time.
