[Libav-user] does ffmpeg/ffplay has any known issue with swf format?

[黄轩宇]

Hi Guys,

I met a failure when calling av_seek_frame to seek into a swf file
(function returned -1).
While I tried to play this file with ffplay, it also reports an error when
I seek to a position.

Below is the output from ffprobe, and here is the video link

Can anyone take a look at it?

Thanks
