For future errors: Please always provide complete, uncut console output (not an excerpt of the console output) and please do not report multiple issues in one ticket (this makes following the reports impossible), but always open one ticket per issue.

The first issue you report here is invalid, see for example https://ffmpeg.org/trac/ffmpeg/wiki/SupportedMediaTypesInFormats for a list of supported formats in flv (it makes no sense for FFmpeg to mux formats into a flash file that no player would be able to decode).

The second issue is a duplicate of ticket #1230.

Thanks, for reply!
So, for first video will be imposible to convert this video, right?
For second - i saw in the ticket #1230 and if I understand, the problem will be solved with 'mencoder', right? But how to use it in console?
Thanks!

Replying to PR:

Afaict, there is no reason to assume that FFmpeg cannot convert your video.

For second - i saw in the ticket #1230 and if I understand, the problem will be solved with 'mencoder', right?

I would not say that MEncoder "solves" any problem, but I believe MEncoder can decode your sample.

But how to use it in console?

It can only be used "in console"

I'm a little confused...
Is any chance to convert first video?
And what is command for MEncoder?
Thanks!
