[FFmpeg-devel] [PATCH] avformat/rtmp: Increase filename size to allow for longer playpaths

[Adam Wall]

The current filename length for the stream name when RTMP is acting as
a server is too short. Certain services such as Amazon IVS use very
long streamkeys (close to 500 characters) when using the new enhanced
RTMP multitrack feature.

When using software such as OBS that can utilize Amazon IVS multitrack
and specifying a custom RTMP server, where that server is FFmpeg RTMP
in listen mode, then the key that gets passed over the publish
commands exceeds the current 128 length limit, resulting in a "name
too long" error.

This commit simply increases the filename size to accomodate these
longer stream names.
