    I'm enjoying the quality. It's way more respectful to the In-Game Dota feel than twitch.
    However, it's not +720p, but it's mostly due to my poor Internet. But at least changing quality is not causing some latence or so.

    That's cool. Last thing I would want is a way to watch the stream in another window.

      Look great. I would like for cursor to disappear when you don't move it for some time, though.
      Possible solution to foreigners issue

        This is a 1920x1080 60fps stream, and in addition to doing some load testing, we're interested in your feedback:
        • How do you feel about the video quality? Resolution, framerate, color, contrast, etc.
        • How is your connectivity to the stream? Do you experience lag? Reconnections? Down-rezzing? (if so, where are you located?)
        • How is the transcode quality?
        • Do you have any other feedback about the stream?

        The machine streaming this will be auto-spectating games, so it should switch from game to game as they finish, and will be broadcasting the English casters.

        Thanks!
        Video color/contrast is slightly off. Video is blurry considering 3.5m 1080p stream. This is most likely due to 60fps. Video crispiness is much more important than 60fps.

        The stream UI is extremely bad. On top of that, it is not touch optimized at all.

          just for a 720p 45-55% of my cpu was working for it, watchable.
          ( i was watching on steam web browser , i3-2365 1.4GHz, using wondows 7. my laptop is an Asus F550C)
          if i disconnect my charger i get something like 3-4 fps both in audio and video.
          480p and sub are watchable even with my charger disconnected.
          for comparison i can watch Twitch on "high" with my charger disconnected as it requires only 13% of my cpu.

          ofc i am on a shitty machine and most steam users have better stuff( and yet i can run Dota2! painfully.) but some have it like me, or just want to watch stuff while also having something casually running in the background or while being on a battery(phones?).

            Mozilla Firefox verison 38.0.1
            The fact that I can not watch it with Firefox just Chrome or Safari makes me mad as hell!

              1080p using steam browser runs fine, does feel a bit blurry.

              If I use Auto quality it just jumps all around leading to lag.

              If I watch the stream in the most recent chrome browser the video freezes for a few seconds pretty often while audio continues.

                  would be better if the video is a little brighter and the rest is all okay!

                    It's choppy when camera moves fast and it's way to dark.

                      I second this. 60 fps is nice, but I'd like to see how much crisper it looks at 30 or 45 fps. I think the extra picture quality would easily make up for the fps difference.

                      Audio quality is also all over the place, but that's more so an issue with the tournaments audio setup. Dota TV just always sounds worse than Twitch.

                        Will this count as watching matches like twitch does?
                        The quality is really nice, but I can only watch it in steam http://puu.sh/i4ZfH/284b07d36f.png this pops up when I open the link in Chrome

                        Edit:
                        1. Sometimes the stream lags
                        2. If you open it in Fullscreen on a 2nd screen and switch the focus to another window both screens go black for a moment.

                          CvP is right about the stream being slightly blurry. Imo it's okay-ish but a sharp 30 fps version would be useful.

                          Occasional stuttering (sometimes sound, rarely video) and rather frequent chat disconnects and reconnects from Germany.
                          If you think I've closed or deleted a post unjustified, feel free to PM me and I'll explain it to you/discuss it with you further.

                            The sound is the spectator watching dotatv, not the stream

                              • its a bit blurry
                              • no theater mode (full window with only stream + chat), or at least I cant find it
                              • I think you should make it a separate product, i.e. its own domain for it to succeed and compete with other streaming services. This is kind of a niche feature hidden under some menu in steam...

                                The audio of the commentators sounds quite a bit lower quality compared to twitch.
