Sorry, I attached the wrong file.

The file that shows the behavior is 3.3MB big.

How can I attach it to this bug report?

comment:2 by ousia, 9 years ago

File can be found at

Please, tell me when can I remove the file from the server.

I remove the attachment with a zero-byte file.

Resolution: fixed

Will be fixed in 2.1.6.

Could you explain why you are using an unmaintained release series although a compatible maintained release series exist? Or is the information shown on and unclear?

comment:4 by ousia, 9 years ago

Many thanks for the fix.

RPMFusion offers that version for Fedora 20.

comment:5 by ousia, 9 years ago

Following your advice, I recompiled ffmpeg-2.3.3 and the error is gone.

There is only an error message such as:

[opus @ 0xae6006c0] Error parsing the packet header.=    0B f=0/0   

This is fine for me, but I don’t know whether it should be fixed.

Many thanks again for your help.
