I just tried that, and no crashes.

Code:
youtube-dl -f 399+bestaudio https://www.youtube.com/watch?v=k2qgadSvNyU
Output file works fine for me.

Doesn't seem as straightforward as it first did. It doesn't always crash, bat apparently always if I try to play after a fresh start of the player.

I only get this message:


So I have no clue how to verify if the crash in fact happens within LAV.

The closed caption change causes MPC-HC to freeze when opening a DVD.

I have a question about the Advanced Track Selection, i set to:
Audio: eng,ger
Subtitle: eng:eng|f;ger:ger|f;*:off

After using a Header Editor to fix the incorrect und marked audio track to eng and making sure the forced sub track is correctly set, the subtitle was not selected.

After some time i discovered that the file ad Tags in them and this is probably the reason didn't work since the tag says also und as audio language.

Code:
    <Targets>
      <TrackUID>1</TrackUID>
      <TargetTypeValue>50</TargetTypeValue>
      <TargetType>MOVIE</TargetType>
    </Targets>
    <Simple>
      <Name>CREATION_TIME</Name>
      <String>2018-09-05 17:15:26</String>
      <TagLanguage>und</TagLanguage>
      <DefaultLanguage>1</DefaultLanguage>
    </Simple>
    <Simple>
      <Name>LANGUAGE</Name>
      <String>und</String>
      <TagLanguage>und</TagLanguage>
      <DefaultLanguage>1</DefaultLanguage>
    </Simple>
Is this the way it suppose to work? Prioritize the Tags over the set language in the header.

I think I found a bug in FFmpeg.

In libavformat/mov.c function mov_seek_stream
Code:
timestamp -= (sc->min_corrected_pts + sc->dts_shift);
Seems wrong to me. Because for index entries min_corrected_pts is already subtracted in function mov_fix_index. dts_shift is also already added to min_corrected_pts.

I have a MP4 where seeking to keyframe was slow because of wrong timestamp value. Removing the above line fixes that.

mov_fix_index is not used by LAV, and that line isn't new in the latest build. So that doesn't seem right to me. Please provide a file that seeks slower then it used to.

It isn't a recent bug, but already before 0.72. Will PM a link.
