Subject: Mp4: fix seeks to standalone last chunk.
X-Git-Tag: release-1.5.10~10
X-Git-Url: http://git.kaiwu.me/postgresql/log/contrib/postgres_fdw/static/gitweb.js?a=commitdiff_plain;h=d3e0bf306b86ac08b828886e75b8c30218a16377;p=nginx.git

Mp4: fix seeks to standalone last chunk.

If seek position is within the last track chunk
and that chunk is standalone (stsc entry describes only
this chunk) such seek generates stsc seek error. The
problem is that chunk numbers start with 1, not with 0.
