Error configuring filters.

Seems like an error in the parser:

[Parsed_join_0 @ 0284c0e0] Output channel 'SL' is not present in requested channel layout.

Please add some information about what you are trying to do.

[burek]

I'm not experiencing this issue, I'm just relaying the forum post. Please read it.

[Carl Eugen Hoyos]

As said, it is necessary to post all information into the forum, please do not use external resources, and please only report issues here that you can reproduce yourself (except if there is a reason why the issue cannot be generally reproduced).

That said, this page should explain the usage issue:

cehoyos failed to say that channely layout 5.1 does not have SL channel.

Channel layout 5.1 does not have side left (SL) channel, but 5.1(side) does.

1. join is flawed by design; please use amerge and pan.

2. "You can view the entire thread here": no: "You need to login in order to reply to topics within this forum", and that is out of question.

3. "Seems like an error in the parser": no:

   ffmpeg -layouts |& grep 5.1
   5.1         FL+FR+FC+LFE+BL+BR
   5.1(side)   FL+FR+FC+LFE+SL+SR
   

5.1 has no side channels.

1. ok
2. i apologize, i pasted a wrong url, this one is valid: ​http://ffmpeg.gusari.org/viewtopic.php?f=11&t=849
3. ok, thanks, I'll update the forum thread with this and it will hopefully solve the issue.

[burek]

Btw, does this documentation need a correction perhaps: ​http://www.ffmpeg.org/ffmpeg-filters.html#join
Because, that's where the example command line in question was taken from.
