Running VLC from the shell in Android and also passing in a subtitles file?

I thought of a way to get an Android script to accomplish this:

(1) create an empty "work" directory;

(2) copy the VideoToPlay.mp4 file into that work directory;

(3) copy the *.ssa file into the same directory under the name "VideoToPlay.ssa";

(4) run the "am start" command I posted above, pointing to the VideoToPlay.mp4

This works because as long as there is an .ssa file in the same directory as the video and with the same base name as the video, VLC will apply the subtitles in that .ssa file to the specified video.

Here is my script to accomplish this:

#!/system/bin/sh workdir=/sdcard/vidwork amstart=( /system/bin/am start -n org.videolan.vlc/org.videolan.vlc.gui.video.VideoPlayerActivity -a android.intent.action.VIEW -d ) amstop=( /system/bin/am force-stop org.videolan.vlc ) # If VLC is running, kill it. "${amstop[@]}" 1>/dev/null 2>&1 [[ $# -lt 1 ]] && { echo " usage: ${0##*/} video-to-play [ subtitle-file ] " exit 1 } videopath="${1}" shift [[ -r "${videopath}" ]] || { echo " Video doesn't exist: ${videopath} " exit 1 } videoname="${videopath##*/}" case "${videoname}" in *.mp4|*.mkv) ;; *) echo " Video must be mp4 or mkv " exit 1 ;; esac videobasename="$( echo "${videoname}" | /system/bin/sed -e 's/\.mp4$//i' -e 's/\.mkv$//i' )" /system/bin/rm -rf "${workdir}" 1>/dev/null 2>&1 /system/bin/mkdir -p "${workdir}" 1>/dev/null 2>&1 [[ $# -gt 0 ]] && { subpath="${1}" shift [[ -r ${subpath} ]] || { echo " Subtitle file doesn't exist: ${subpath} " exit 1 } /bin/cp "${subpath}" "${workdir}/${videobasename}.ssa" } /bin/cp "${videopath}" "${workdir}" cmd=( "${amstart[@]}" "file:///${workdir}/${videoname}" ) { "${cmd[@]}" } 1>/dev/null 2>&1 exit 0 

PS: This script needs to run as root in order for the /system/bin/am force-stop ... command to function properly.

Therefore, assuming this script is stored as /sdcard/runvid.sh, it needs to be run on a rooted device as follows ...

/system/bin/su -c /sdcard/runvid.sh path-to-video-file [ path-to-subtitle-file ]
