Original HLS source (requires US IP): https://tve-vod-preview.cdn.turner.com/toon/c26e41c4570090fca8e550ecca41df0b/layer1/layer1.m3u8

Additional information

With version 0.94, CCExtractor only extracts when I remux the HLS stream to MPEGTS with ffmpeg -i <hls link> -c copy test.ts. If I remux it to MP4 (ffmpeg -i test.ts -c copy test.mp4), CCExtractor throws a Segmentation fault.
