Making some assumptions about that. :)

Have seen this with all f4ms.

It plays fine, but spits out lots of errors:

And ffmpeg (a fairly recent version) complains a lot (and produces an output file with the same problem):

BUT, mkvmerge has no problem with this:

The file 'file-NA.mkv' has been opened for writing.
'file-NA.flv' track 0: Extracted the aspect ratio information from the MPEG-4 layer 10 (AVC) video data and set the display dimensions to 1280/720.
Progress: 100%
The cue entries (the index) are being written...
Muxing took 2 seconds.

The mkvmerge output file not only plays without any warnings or errors, but ALSO ffmpeg can handle the output file (converting, copying into other containers) without any warnings or errors.

I don't know where this comes from (maybe ffmpeg is putting the segments together and it is an ffmpeg bug?), but (even though this isn't something critical, it seems worth pointing out. Thanks.

Happens with every f4m video I have ever downloaded, but in the spirit of the day, I will offer this link:

I guess the problem is from ffmpeg rather than youtube-dl. Here's a relevant bug report: https://trac.ffmpeg.org/ticket/4011. Could you update ffmpeg to the latest version (2.6.3) and try again?

Sorry that took so long (I had to recompile half of my system when I upgraded ffmpeg :) ).

It works flawlessly with ffmpeg 2.6.3.

Thanks (and sorry for wasting your time).
