Comment (by mmlr):
The problem was the buffer of the IO context. It needs to be freed
manually, but this wasn't done in the error path of `avformat_open_input`.
Since it also resets the `fIOContext` to NULL, the destructor would then
also not free it. This should be fixed in hrev53640.
The resulting leak here would be very variable in size, since
`avformat_open_input` may reallocate the buffer to make it larger. In my
testing, it easily consumed multiple megabytes depending on what input you
fed. So even though the initial allocation is relatively small at 32K, the
eventual leak could be orders of magnitude larger.
