sorry, it took me some time to get hands to L5 again. Both original PinePhone and Librem 5 fail to play h264 video with the same error: ``` (com.github.rafostar.Clapper:59855): GStreamer-CRITICAL **: 15:30:29.052: gst_caps_get_structure: assertion 'index < GST_CAPS_LEN (caps)' failed (com.github.rafostar.Clapper:59855): GStreamer-CRITICAL **: 15:30:29.052: gst_structure_set: assertion 'structure != NULL' failed (com.github.rafostar.Clapper:59855): GStreamer-Video-CRITICAL **: 15:30:29.052: gst_video_info_from_caps: assertion 'gst_caps_is_fixed (caps)' failed ** GStreamer-GL:ERROR:../gst-libs/gst/gl/gstglcolorconvert.c:830:_gst_gl_color_convert_set_caps_unlocked: code should not be reached Bail out! GStreamer-GL:ERROR:../gst-libs/gst/gl/gstglcolorconvert.c:830:_gst_gl_color_convert_set_caps_unlocked: code should not be reached Aborted (core dumped) ``` the problem appeared in 1.24.1 and wasn't on 1.24.0. 1.24.1 introduced DMA_DRM caps support for v4l2codecs and clapper gstreamer sink doesn't support it. I think in 0.6 it's handled by following commit: https://github.com/Rafostar/clapper/commit/681da9e2f39fd5180317113e7349272586ae645d > > If I take old clapper build before gstreamer update to 1.24, then > > videoplayback in clapper works. > > > > I've tried to backport upstream clapper fix for gstreamer 1.24. > > https://github.com/Rafostar/clapper/commit/a9769f95378d1cf20d6f6105eb90df7a3fe3f8f0 > > But it wasn't enough to get clapper 0.5.2 working on PinePhone. > > > > clapper 0.6 contains several fixes for gstreamer 1.24 compatibility. > > I've tried to build clapper 0.6 against gstreamer 1.24 localy and video > > playback started to work on PinePhone. > > I take it then that this is mainly about the PinePhone and not the Librem 5? > > > Please consider updating clapper to the next released version 0.6. > > Certainly!
