      Hi,all
      Now I want to use opera browser to set up a p2p video conference(webrtc),but opera seems that can't play the remote H364 video stream
      Could someone know how to decode H264 with opera on windows,As I know opera Linux version already have the solution.
      P.S I just try to install FFmpeg/ffdshow on my win7 and also install wmp html5 plugin,but all no use.

            If you try to open a local mp4 video encoded with h264 in Opera, does it play?

              @sgunhouse OS is win 7.opera version is 41.

              @leocg ,it does not play,for example ,also can't playback twitter video.
              I notice @avl ever said,on Windows platform,Opera need system natively decode support,does it mean HW decode accelerate?or mean software decode on OS?

                It means that Windows Media Player (or whatever media player that comes with Windows) should be able to play the file encoded in h264 without needing any codec pack to be installed.

                OS is win 7

                Win7 should be able to play h264 videos.

                It's 32 or 64 bits? Your graphic cards supports hardware acceleration?

                Try taking a look at opera://media-internals/ while playing a video (or trying to play), it may bring some info to you.

                  Hi,Legco.
                  My WMP can play MP4 which encoded in H264,but still opera can't.
                  Here is opera://media-internals/ info:

                  "render_id: 172
                  player_id: 1
                  pipeline_state: kStopped

                  range_header_supported: true
                  pipeline_error: pipeline: initialization failed"

                  it display "initialization failed"

                    My win7 is 64 bits and my graphic card is intel HD Graphics 4600 which does not support HW acceleration

                      My WMP can play MP4 which encoded in H264

                      And you never installed any codec?

                      my graphic card is intel HD Graphics 4600 which does not support HW acceleration

                      Yes, it does support.

                      it display "initialization failed"

                      Does opera://gpu shows any error message? Do you see a GPU process in Opera's task manager?

                          If there's a setting change that's causing the problem, going to opera://flags and resetting might fix things.

                            Opera can't use them as far as I know.

                            Do you mean I will unintall them ?

                            No, I mean that Opera can only play H264 (and some other codecs) if Windows can play them natively. In other words, Windows should be able to play those codecs just after having been installed.

                            Did you check the whole page? Real problems are usually listed on the bottom of the page?

                            Also, are the items under 'Graphics Feature Status' with 'hardware accelerated' status? At least most of them.
