Thanks for the quick reply.

I realized that ffio_ensure_seekback() won't be enough because the 
seekback amount is unknown. So it sounds like the codebook data needs to 
be copied somewhere for later use.

Would it be OK to stash a bit over 2 MiB buffer in WsVqaDemuxContext and 
copy the chunk data there? It would then be freed along with other 
demuxer private data and wouldn't leak.
