https://bugs.winehq.org/show_bug.cgi?id=48766 --- Comment #33 from Zebediah Figura <z.figura12(a)gmail.com> --- Let's please just focus on the case with all builtin components—don't install native quartz or mfplat, don't disable winegstreamer; let's instead just debug winegstreamer until it works. Even installing native components and then later setting them to builtin will affect what happens in the prefix. 12463.025:0071:err:gstreamer:unknown_type Could not find a filter for caps: "video/x-h264, stream-format=(string)avc, alignment=(string)au, level=(string)4, profile=(string)high, codec_data=(buffer)01640028ffe1001b67640028ac> It appears from other messages in the log that the "bad" plugins are installed, but openh264dec is missing. Arch builds without it for some reason; I can't easily find the Linux Mint package build scripts but it's not unlikely that it does as well. As a substitute, however, the gstreamer libav plugin should support h264 decoding. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
