This pull requests complements pull request #2178 by reducing general computational time for the method getTimeString.
On my local machine (Desktop PC with Java) my tests with a sample size of 10000 calls to the method with param 86400001 showed a performance improvement of about 50%.
See sample code below to reproduce:
private static final StringBuilder stringBuilder = new StringBuilder();
private static final Formatter stringFormatter = new Formatter(stringBuilder, Locale.getDefault());
public static String getTimeString(int milliSeconds) {
int seconds = (milliSeconds % 60000) / 1000;
int minutes = (milliSeconds % 3600000) / 60000;
int hours = (milliSeconds % 86400000) / 3600000;
int days = (milliSeconds % (86400000 * 7)) / 86400000;
stringBuilder.setLength(0);
return days > 0 ? stringFormatter.format("%d:%02d:%02d:%02d", days, hours, minutes, seconds).toString()
: hours > 0 ? stringFormatter.format("%d:%02d:%02d", hours, minutes, seconds).toString()
: stringFormatter.format("%02d:%02d", minutes, seconds).toString();
}
public static String getTimeStringL(int milliSeconds) {
long seconds = (milliSeconds % 60000L) / 1000L;
long minutes = (milliSeconds % 3600000L) / 60000L;
long hours = (milliSeconds % 86400000L) / 3600000L;
long days = (milliSeconds % (86400000L * 7L)) / 86400000L;
stringBuilder.setLength(0);
return days > 0 ? stringFormatter.format("%d:%02d:%02d:%02d", days, hours, minutes, seconds).toString()
: hours > 0 ? stringFormatter.format("%d:%02d:%02d", hours, minutes, seconds).toString()
: stringFormatter.format("%02d:%02d", minutes, seconds).toString();
}
public static void main(String[] args) throws Exception {
final int SAMPLE_SIZE = 25000;
long[] results = new long[SAMPLE_SIZE];
for(int i = 0; i < SAMPLE_SIZE; i++) {
long now = System.nanoTime();
getTimeString(86400001);
results[i] = System.nanoTime() - now;
}
long sum = 0;
for(int i = 0; i < SAMPLE_SIZE; i++) {
sum += results[i];
}
System.out.println("Average execution time: " + (sum/SAMPLE_SIZE));
results = new long[SAMPLE_SIZE];
for(int i = 0; i < SAMPLE_SIZE; i++) {
long now = System.nanoTime();
getTimeStringL(86400001);
results[i] = System.nanoTime() - now;
}
sum = 0;
for(int i = 0; i < SAMPLE_SIZE; i++) {
sum += results[i];
}
System.out.println("Average execution time: " + (sum/SAMPLE_SIZE));
In VideoPlayer the Duration String is cached effectively by setting it to the playbackSeekBar. As the playbackSeekBar doesn't exist in BackgroundPlayer, using two addition variables will reduce performance impact of notification updates by almost 50% and thus perform similar to VideoPlayer.
This addresses issue #2170
Scenario: listening to a video on NewPipe over Bluetooth and a Notification Sound causes audio focus event AUDIOFOCUS_LOSS_TRANSIENT_CAN_DUCK.
Problem: With the current implementation animateAudio would cause the audio to reach the target volume AFTER the notification sound is played, which is irritating and annoying.
Solution: animateAudio should just be used on focusGain where it is sensible to increase audio gradually. On ducking event the reaction should be immediate.
This very simple fix does this. Please approve.

* save the thread count for next downloads
* a lot of incoherences fixed
* delete DownloadManagerTest.java (too many changes to keep this file updated)
-Previous version used emojis for brightness and volume icons, which may
be inconsistent across devices and do not fit well with other parts of UI
(Frankly, previous version was more informative than eye-candy)
-This commit replaces old version with circular progress bar that shows
current value (before conversion). Gesture mode (volume/brightness) is
indicated by icon that changes between (4/3) modes according to current
value
-Text information about current value was removed, because with progress
bar present it does not add any real value to UI.
-Changed background player notification to no longer update bitmap on progress time change.
-Changed popup player to move above soft keyboard when it is opened.
-Fixed potential play queue desynchronization due to fast forwarding on silence.
-Added current thumbnail storing in base player to allow immediate retrieval for notification building.
-Removed video player buffer spinner during interim buffering but not initial buffering.
-Reverted foreground notification stopping on pause and on complete.
-Updated OkHttp to 3.10.0 and RxJava to 2.1.14.
-Changed player recovery seek to use ExoPlayer built-in window seeking instead of seeking after stream window starts playing.
-Changed playback speed changer default step size to 25%.
-Changed player notification to reset on all state changes.
-Fixed gradle dependency version incorrect variable names.
-Fixed video player double tap not working during pause.
-[#1412] Fixed NPE when sharing video to main video activity when it was playing but is out of focus: Reset main player state when new intent is received.
-[#1410] Fixed fast forwarding and rewinding not working within 10 seconds from beginning or end of a stream window.
-Fixed background and popup player service staying in foreground when playback is paused or completed.
-Fixed player metadata not updating on new stream.
-Fixed player intent playback quality not applied.
-Fixed player auto-queue not applied after stream transition or swapping.
-Added step size selector to playback speed control.
-Added skip silence flag to player intents.
-Moved default preset in playback speed control to neutral dialog button, renamed as reset.
-Removed nightcore preset from playback speed control.
-Updated MediaSource contracts in ManagedMediaSource.
-Changed PlaceholderMediaSource and FailedMediaSource to use built-in BaseMediaSource implementation.
-Changed deprecated DynamicConcatenatingMediaSource to ConcatenatingMediaSource.
-Removed manual playlist media source disposal in favor of player built-in disposal.
This improves downloading performance dramatically when cpu bound:
Before, even a high-end cpu from 2013 can't download faster than around 1MB/s.
The bigger read buffer size removes the need for a dedicated BufferedInputStream.
- add HistoryInfoItem (deriving from StreamInfoItem)
in order to add a special options menu for the list items
- delete HistoryActivity and everything that belongs to its UI (not the
manager tho)
- put everything that is local into local. (subscriptions still missing)
* Added a dropdown to video & audio settings
* Changes to ListHelper:
** Limits resolution when code requests the default video resolution
** Limits audio bitrate when code requests the default audio bitrate
** Removed some dead code and did some cleanup
** Make methods private/protected to help understand what was in use
** The code now chooses one format over an other using a simple raking system defined in array constants. I realized I needed to do this in order to choose the most efficient video stream. I did my best to evaluate the video and audio formats based on quality and efficiency. It's not an exact science.
