ffprobe wrongly reports "Operation not permitted"

[gillux]

I'm trying to inspect the contents of a (presumably corrupted) TS file I found on the internet using ffprobe. Ffprobe quits with a wrong error message: Operation not permitted.

There is nothing wrong with the permissions. As -v debug suggests, the file is opened and even detected as mpegts. As I compiled ffmpeg with DEBUG defined, the console output with -v debug is really long so I attached it. I also put the TS file on the FTP under the name operation_not_permitted.ts.

ffprobe with -v debug

I wonder what ffmpeg / ffprobe should output for a transport streams that contains no useful streams...
Or do I miss something and there is software that does something useful with the stream / is there anything inside the stream?

The TS file indeed appears to be detected as having no stream. gdb told me that avformat_find_stream_info() returns -1 and skips most of its code since ic->nb_streams == 0. This -1 is then interpreted as a the POSIX errno EPERM, thus the "Operation no permitted" error. If I make avformat_find_stream_info() not to return -1, ffprobe seems to work well and gives the following output:
