Body

I am trying to save an mp4 file after trimming with the help of its url. I am using https://github.com/a914-gowtham/android-video-trimmer for trimming my video and the updated uri after trimming is fine as I trying playing it in exoplayer and it works, the problem happens when I try to save it to external storage. I can see my file being saved to external storage as well but when I try to play it after saving via third party apps like vlc, mxplayer etc they throw error. So below is my code to save video after getting the uri

You can use this method to save the video in device's having android 10 or above.

Just pass the file and display name.

@RequiresApi(api = Build.VERSION_CODES.Q)
@throws(FileNotFoundException::class)
fun Context.addVideoToGalleryAPI29(
file: File,
displayName: String,
exportListener: VideoExportListener
) {
val savePath = (Environment.DIRECTORY_DCIM
+ File.separator + file.name)
val cv = ContentValues()
cv.put(
MediaStore.Video.Media.RELATIVE_PATH, Environment.DIRECTORY_DCIM
+ File.separator + File(savePath).name
)
cv.put(MediaStore.Video.Media.TITLE, "${displayName}.mp4")
cv.put(MediaStore.Video.Media.DISPLAY_NAME, "${displayName}.mp4")
cv.put(MediaStore.Video.Media.MIME_TYPE, "video/mp4")
cv.put(MediaStore.Video.Media.DATE_ADDED, System.currentTimeMillis() / 1000)
cv.put(MediaStore.Video.Media.DATE_TAKEN, System.currentTimeMillis())
cv.put(MediaStore.Video.Media.IS_PENDING, 1)
val resolver = contentResolver
val collection =
MediaStore.Video.Media.getContentUri(MediaStore.VOLUME_EXTERNAL_PRIMARY)
val uriSavedVideo = resolver.insert(collection, cv)
val pfd = contentResolver.openFileDescriptor(uriSavedVideo!!, "w")
if (pfd != null) {
try {
val out =
FileOutputStream(pfd.fileDescriptor)
val inputStream = FileInputStream(file)
val buf = ByteArray(8192)
var len: Int
while (inputStream.read(buf).also { len = it } > 0) {
out.write(buf, 0, len)
}
out.close()
inputStream.close()
pfd.close()
cv.clear()
cv.put(MediaStore.Video.Media.IS_PENDING, 0)
} catch (e: Exception) {
e.printStackTrace()
}
contentResolver.update(uriSavedVideo, cv, null, null)
}
exportListener.onVideoExported()
}
