Ignore load errors in subtitle tracks sideloaded using SingleSampleMediaSource #3140
Description
I am using MergingMediaSource in order to display Video and subtitles. For some reason the text source file might be removed from the server so the url will return 404, giving the following exception com.google.android.exoplayer2.upstream.HttpDataSource$InvalidResponseCodeException: Response code: 404
At this point it makes sense, the problem is I can't play the video if this happens although I expect that if the text source is not found, I could at least play the video.
Below you can find the code snippet for preparing the media links
MediaSource videoSource = new ExtractorMediaSource(mp4VideoUri, dataSourceFactory, extractorsFactory, null, null);
Format textFormat;
MediaSource[] mediaSources = new MediaSource[videoDetailsModel.getVideoSubtitleModels().size() + 1];
mediaSources[0] = videoSource;
for (int i = 0; i < videoSubtitleModels.size(); i++) {
VideoSubtitleModel videoSubtitleModel = videoSubtitleModels.get(i);
textFormat = Format.createTextSampleFormat(null, videoSubtitleModel.getCaptionMimeType(), null, Format.NO_VALUE, Format.NO_VALUE, videoSubtitleModel.getCaptionSrcLang(), null);
mediaSources[i + 1] = new
SingleSampleMediaSource(Uri.parse(videoSubtitleModel.getCaptioningUrl()), dataSourceFactory, textFormat, C.TIME_UNSET);
}
MediaSource mediaSourceWithText = new MergingMediaSource(mediaSources);
// Prepare the player with the source.
player.prepare(mediaSourceWithText);
