Stuttering Playback of EIA-608 POPON Closed Caption
Transport Stream with H.264 with embedded EIA-608 that uses POPON captions instead of ROLLUP captions. If you play the stream with Subtitle playback disabled, it plays back fine. If you enable Subtitle|SubTrack|Closed Caption 1 it plays back with lots of video frame drops.
Tested with VLC-2.2.2-Weatherwax on Linux and Windows8.1. Observed the same issue on both platforms.
Lots of messages in the log at log level 2:
