12 months ago here's one BV1Pv4y1B7JV that seems to have a moov problem that fails ffmpeg transcoding:

rarely android gets one of these, iOS seems to be plagued by it. to be fair sometimes its not ios' fault but still, screw you apple. APM hypothesizes its AVPlayer not supporting some formats, very notably MPEGDASH, causing some media to not play. there is also https://www.bilibili.com/read/cv14674639/ that does seem relevant. APM attempts to resolve this issue by using the bundled FFMPEG to re-encode whatever bilibili has into mp3 to make it playable. also CDN kamaized.net seems fine but bilivideo.com is not.
