Multiple CC tracks support in Transport Stream files #2161

bene25 · 2016-12-06T12:39:09Z

Hello. How I could get multiple subtitles embeded in .ts file?

trackInfo = trackSelector.getCurrentSelections().info;
trackGroups = trackInfo.getTrackGroups(2);
trackGroupsAdaptive = new boolean[trackGroups.length];
for (int groupIndex = 0; groupIndex < trackGroups.length; groupIndex++) {
TrackGroup group = trackGroups.get(groupIndex);

trackGroups return only one subtitle though there are 3 subtitles.

Subtitles format CEA-608

You could find stream details here: #2056

Any help for this issue?

We still don't have proper support for multiple CC services. This is on the map, possibly Q1. I will use this issue to track this.

I am working on adding multiple CC support now. However, the stream you provided doesn't seem to include 608, but rather DVB subtitles. I am speaking about the file provided here. If you have a TS with multiple 608 channels, or even better, an HLS stream, please send a link to dev.exoplayer@gmail.com. This should speed up the process.

As far as I know, HLS does not support dvb subtitles.

This CL is a no-op refactor but allows defining the outputted channels through the TsPayloadReaderFactory. Issue:#2161 ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=146243736

This allows the TsExtractor to automatically determine the closed caption tracks to expose by parsing available descriptors. Issue:#2161 ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=148321380
