Strange "-f" issue

[josephomorrow]

When attempting to download certain videos, I get this weird error:

ERROR: The first format must contain the video, try using "-f 140+258"

140          m4a        audio only DASH audio  127k , m4a_dash container, aac  @128k (44100Hz), 675.21KiB
258          mp4        audio only  386k , mp4a.40.2, 2.00MiB (best)

Both formats audio only. First must be video, second audio.

Hello dstftw,

Apparently you didn't look at the command line I issued. I didn't enter "-f 140+258" or "-f 258+140"! What I entered was "-f mp4+m4a" (see script listing near top of my attachment). Also note that only occasional videos produce this error message. Most work OK!

Thanks for not being hasty,

Joseph

 Please see the new comment I just added to the "closed" issue. Apparently the parser sometimes reads my "mp4" to mean "audio only" instead of "video only". On 12/08/15, Sergey M.notifications@github.com wrote: Closed #7801.—Reply to this email directly or view it on GitHub.
