WRITE DESCRIPTION HERE
while downloading videos from safari online lesson it just downlods fists part of video which is only 1 minute long. It does't continue download to other hls part of video . I think the reason the json file which contains video part info of video isnt readable or unaccesable. The Error is:" WARNING: [safari] 9781789131550-video1_1: Failed to parse JSON No JSON object could be decoded"
