[vlc-devel] [PATCH v3 1/1] avformat: replace deprecated field in AVFormatContext

[Mehdi Sabwat]

From: Mehdi Sabwat <mehdisabwat at gmail.com>

Since Jan 21, 2018 (ea3672b7d67c432724bdbc8de0221f869b6a04c6)
filename field was deprecated in favor of `url` which now has
no length restrictions.

```
2018-01-28 - ea3672b7d6 - lavf 58.7.100 - avformat.h
  Deprecate AVFormatContext filename field which had limited length, use the
  new dynamically allocated url field instead.
```
