html5 video not buffering ahead

Post by h3po4 » 2017-01-08, 14:36

For a couple of weeks now (I think since v27.0.1) html5 video has not been working properly on my two arch linux systems. When I saw this changelog for 27.0.3 I thought it might've been fixed, but the problem persiststs:

Code: Select all

Fixed an error in the buffer logic in http-chunked decoder.
Video plays back fine, but it does not buffer ahead of time. The total video length counts upwards in sync with the current playback time and it is not possible to skip ahead; doing so either restarts the video from the beginning or skips to the end. Seeking backwards works. This happens for me on all Youtube videos and also all sites using jwplayer. The only site I found where it works properly is ZDF Mediathek (https://www.zdf.de/)
Here's an example screenshot of a 3+ Minute youtube video showing 1s as the total time right after starting the playback:

pacman -Q gstreamer gst-plugins-good gst-libav 
gstreamer 1.10.2-1
gst-plugins-good 1.10.2-1
gst-libav 1.10.2-1
If anyone could suggest sites using different players I'd be happy to try them out and report back if it works there.

This video works just fine, it buffers in play and paused and I can skip ahead and back.

It's a known issue with GStreamer 1.10. This will no longer be an issue in our next release as we will be using FFmpeg directly instead of GStreamer for H.264 video.

Problem present in the version 1.95 also. Try to downgrade gstreamer1 to version 1.8.3, as workaround.

For my fc25 I took rpm-s from fc24. It helped me.

Code: Select all

# rpm -qa | grep ^gstreamer1 | sort
gstreamer1-1.8.3-1.fc24.x86_64
gstreamer1-libav-1.10.2-1.fc25.x86_64
gstreamer1-plugins-bad-free-1.8.3-3.fc24.x86_64
gstreamer1-plugins-base-1.8.3-2.fc24.x86_64
gstreamer1-plugins-base-tools-1.8.3-2.fc24.x86_64
gstreamer1-plugins-good-1.8.3-2.fc24.x86_64
gstreamer1-plugins-good-extras-1.8.3-2.fc24.x86_64
