саппорт в лице Vladyslav Ursul и Evgeniy Burlaka настойчиво предлагает записать поток, найти проблемный момент и отослать этот поток им, но фишка в том, что бага выплывает только про проигрывании по http. при воспроизведении с флешки или по самбе потока, записанного ПОБАЙТОВО, бага не выплывает.
на вопросы, могу ли я самостоятельно задебажить этот участок, в ответ молчание.
скорее всего придётся отправлять железо в Одессу.
