which is used in a ClipMediaSource started as 9791ms. Unfortunately, the video is started from about 7000ms.

The reason is because the second ts segment in the m3u8 playlist is marked as #EXTINF 1s but actually lasts for 3s. HlsMediaChunk adjusts the timestamp by startTimeUs which is written from #EXTINF. Eventually TimestampAdjuster adjust sample timestamp by a wrong timestampOffsetUs.

HlsMediaChunk.java

private void loadMedia() throws IOException, InterruptedException {
    if (!isMasterTimestampSource) {
      timestampAdjuster.waitUntilInitialized();
    } else if (timestampAdjuster.getFirstSampleTimestampUs() == TimestampAdjuster.DO_NOT_OFFSET) {
      // We're the master and we haven't set the desired first sample timestamp yet.
      **timestampAdjuster.setFirstSampleTimestampUs(startTimeUs);**
    }
    feedDataToExtractor(dataSource, dataSpec, mediaSegmentEncrypted);
  }

TimestampAdjuster.java
public long adjustSampleTimestamp(long timeUs) {
    if (timeUs == C.TIME_UNSET) {
      return C.TIME_UNSET;
    }
    // Record the adjusted PTS to adjust for wraparound next time.
    if (lastSampleTimestampUs != C.TIME_UNSET) {
      lastSampleTimestampUs = timeUs;
    } else {
      if (firstSampleTimestampUs != DO_NOT_OFFSET) {
        // Calculate the timestamp offset.
        **timestampOffsetUs = firstSampleTimestampUs - timeUs;**
      }
      synchronized (this) {
        lastSampleTimestampUs = timeUs;
        // Notify threads waiting for this adjuster to be initialized.
        notifyAll();
      }
    }
    **return timeUs + timestampOffsetUs;**
  }

Hope you guys can help, thanks.

This doesn't seem like something that should fall on the client. Closing as bad media.

Hiding and displaying the system bars is handled by application code rather than by ExoPlayer, so it's somewhat unclear to what extent this is an ExoPlayer issue. If you'd like us to take a look at what's going on, please could you provide a simple GitHub project that we can clone to reproduce the issue? Thanks!

We were earlier using ConcatinatingMediaSource to prepare our player. While creating mediasource, we were using the following to enable chunkless preparation for HLS: HlsMediaSource.Factory(dataSourceFactory).setAllowChunklessPreparation(true);

Now, we are moving to using MediaItems instead of mediasource to keep our app in line with latest releases of exo sample app. How can we enable chunkless preparation using the new flow: MediaSourceFactory mediaSourceFactory = new DefaultMediaSourceFactory(dataSourceFactory) .setAdsLoaderProvider(this::getAdsLoader) .setAdViewProvider(playerView);

Marking as needs more info until the updated bug report has been provided.

Marking "needs more info" because insufficient information was provided to make it clear what's being asked.

The solution in our case was simply to do as detailed by @starchey above and not use a caching DataSource

Yeah, I'm surprised there is no way to show a placeholder image then when prepare and play go, hide that image and show video. Should be an option unless there is something blocking that from happening. I will just wrap an image view and show hide when player is prepping.

I have looked a bit more into it, but it seems like with the workaround all the other info is also set appropriately.
The position and duration is correct, and the MediaItem is also there.

I can not see the internal tracker, so I might be missing something. But since it looked fine to me I created a pull request.

The amount of depreciation is fairly minimal in 2.12.1, only AdsMediaSource was: r2.12.0...r2.12.1. I would suggest either backporting the fix or updating to 2.12.1.

We error on deprecation in our builds either you suppress or fix. Client does not like to suppress.

After connecting to a cast device that is already playing, the CastTimeline would initially stay empty.
And in turn all methods that rely on the timeline would also report incorrect data.

The reason for this is that the MediaQueue would always return an empty array as active ids until there are further state changes on the cast. This does appear to be an issue in the cast framework, but it can easily be worked around by checking the MediaStatus instead.

Fixes https://github.com/google/ExoPlayer/issues/9026

AudioManager.adjustStreamVolume will mute the music stream of the whole device. It will mute all other application too, and persist after the application is closed. This is identical to the user pressing the mute button on the remote/system ui.

It is highly unusual for an application to change the stream volume or mute it. Apps are expected to use Player.setVolume:https://github.com/google/ExoPlayer/blob/b2333c86c1eac9a1f95992960a8495f1e5b79200/library/common/src/main/java/com/google/android/exoplayer2/Player.java#L1717-L1722

This will only impact the volume of the player this is called on.

As per why AudioManager.adjustStreamVolume failed, I can't tell without a bug report. Can you change the volume by using the volume buttons or the remote control while playing? If the tunneled media doesn't change loudness when the volume is changed, then the device has an hardware issue.

Hello, I'm getting error by Crashlytics, I couldn't reproduce this issue myself so I have only the stacktrace I'm getting from Crashlytics. From my understanding it's trying to read a video mp4a but fails to do so

• ExoPlayer version number: 2.14.0
• Android version: 4.4.2
• Android device: alps M

Yes you're right only a few users are affected by it and this bug seems to be only on Android 4. So I think we can discard this bug :)

Just tested it and it works very well :) Thank you

I didn't try, but based on typing the error number (16976906) into Google, I think it's likely you're hitting this bug in FFmpeg: https://trac.ffmpeg.org/ticket/8428

It looks like the fix made it into FFmpeg 4.3, where-as our FFmpeg extension instructions still recommend 4.2.

I'd suggest you try using FFmpeg 4.3 instead. If that works please let us know, and we'll update our guidance.

i facing same issue POCO M2 Android 10 in ExoPlayer #2.14.1.

the m4a files i have those from iTunes and then transferred them to an Android phone song_test.zip

Hi, do you plan to fix for that? Would be great. Thank you.

Could you please also comment which device is affected?

Please reopen if this doesn't fix your issue.

The amount of depreciation is fairly minimal in 2.12.1, only AdsMediaSource was: https://github.com/google/ExoPlayer/compare/r2.12.0...r2.12.1. I would suggest either backporting the fix or updating to 2.12.1.

@ojw28 Thanks for your reply.

Do I understand correctly that when the player is recreated, the ad request will be repeated and the ad will start playing from the beginning?

Is it possible not to re-request the ad again and save the place where the ad stopped?

Thanks for the help!

The problem with your approach is that the views are all being recreated (because you're not using configChanges = "orientation"), but the player is not.

Hence you're effectively moving playback from one set of views to another. We don't support this for ad playbacks at the moment, unfortunately. It would be good for us to provide support, but this may also require changes in the IMA library, so I'm not sure how easy it would be. Marking this issue as an enhancement.

As of today, your options are to avoid recreating the views (like the demo app does with configChanges = "orientation") or to recreate the player (like the demo app does if you remove configChanges = "orientation"with no other changes). Unfortunately the second option doesn't produce a particularly seamless transition, so I can see why it's not a very good solution.

If your goal is to implement an ABR algorithm for DASH and/or HLS then you'll need to implement a custom TrackSelection. As a starting point, I'd suggest you look at AdaptiveTrackSelection in the library, which is the built in ABR algorithm. The quality evaluation happens in AdaptiveTrackSelection.updateSelectedTrack. It may be easiest for you to start by forking AdaptiveTrackSelection and editing it to suit your needs.

To actually use your custom TrackSelection implementation, create a DefaultTrackSelector using the constructor that takes an ExoTrackSelection.Factory factory.

Have you tried using the FLAC extension? It looks like we removed any restriction on sample rate in this commit, which would suggest that playback might work from 2.11.2 and above.

If it doesn't please provide complete information as requested in our issue template, including reproduction steps.

Hi, I have a android project using Exoplayer to play music.Now I have a project function to play DXD audio files.This audio files is flac files which format is 384kHz/24bit or 352.8kHz/24bit.Most of mobilephones do not support the sample rate.So,is there any solutions? My solution is to resample these DXD files to 192kHz or 176.4kHz,then play them.Is there any functions to resample flac files in Exoplayer? Thanks.

On devices which android version higher than 9 work fine. But on devices which is lower than 9 there is no sound while playing flac audios. On android 9 devices some work well but some no sound while playing flac audios. I am using verison 2.12.0.
Thanks.
