.MKV Qt5 vs Gstreamer Library support

[Hung Tran]

Hi all,

I want to ask that: How Qt5 and Gstreamer play .MKV video. I see in some document that: Qt5 just plays mo4, Avi. But I also want to play .MKV file.

Thank

@Hung-Tran You need to check whether GStreamer can play MKV. Qt just uses GStreamer for media files. For MKV you probably need to install the correct GStreamer package, which one I don't know. Check which GStreamer packages your Linux distribution provides.

@jsulm Thank. I have played .MKV by gstreamer by command line. However, when I play using Qt5, Playback is high lag.
Message from gstreamer: A lot of buffer are being dropped. Do you know why ?

What version Qt, OS you using, I play .mkv with Qt5.8 & Ubuntu 16.04, I work fine, I using Media Player Example in Qt samples.
