Research direction

Start by reproducing the reported errors with the linked Big Buck Bunny MP4, comparing the livepeer.com API and livepeer-transcode paths. No source files, tests, entry points, or acceptance criteria are named; the issue is complete only once the transcoding failure is diagnosed and the expected handling is defined.

Written by the indexing model from the issue text.
