This PR is a workaround for an issue discovered by OSS-Fuzz when trying to parse a SDP with a large number of lines.
Long story short, the
g_strsplit
function is not efficient when dealing with string with a lot of delimiter (\n
) occurrences.As a consequence we limit the number of SDP lines to
10000
in order to avoid the timeout on OSS-Fuzz and work around the issue in Janus.Of course this is not the optimal solution since we do not want to hardcode a number of lines. In the long term we plan to rewrite the splitting algorithm to avoid such inefficiencies.
