Video file to be tested on: http://tv4play.se/program/nyheterna/10002198

When downloading this video file using the Python library, it fails during FFMpeg conversion.
When downloading it via command line, it works flawlessly.

This is a new regression, since 30 may.

Outdated avconv not capable of merging properly. Nothing to do with youtube-dl.

[hakanw]

Thanks @dstftw ! It would be awesome if youtube-dl could warn if you're using a too old ffmpeg. But maybe that's difficult?

[dstftw]

Well, it's hard to be 100% sure whether it fails due to outdated version, malformed source files or something else. So it's barely possible to output warning at an appropriate occasion. A general rule when you encounter some merge/postprocessing error is to check for a newer version of avconv/ffmpeg.

[hakanw]

Understood. Thanks a lot for your hard work, and the most awesome python package!! 2018-06-11 18:07 GMT+02:00 Sergey M. <notifications@github.com>:
