Unexpected demuxer behavior for FFmpeg configured with "disable-decoders"

Reported by: rgadkari Owned by:

Version: git-master Keywords:

Analyzed by developer: no

Description

Summary of the bug:
We are using only the demuxer functionality of FFmpeg in an application. FFmpeg has been configured with "disable-decoders" option, hence no enabled decoders are present.
When the function - avformat_find_stream_info is invoked, it further calls find_probe_decoder, but since no decoders are enabled, it causes seg-fault or unexpected behavior.

Configuration -
./configure --enable-shared --disable-encoders --disable-decoders --disable-optimizations --enable-debug --disable-stripping --enable-logging

Please provide backtrace, disassembly and register dump and explain how I can reproduce the issue.
