UPD: I guess I found the problem. For some reason, 1800x1080 video aren't playing while same vid resized to 800x480 with same set of encoding settings is working just fine. So the question is: why I couldn't play video with res. bigger than the size of my screen?

I'm trying to build a simple video-streaming app for android.

For the purpose of testing, I used this video http://www.quirksmode.org/html5/videos/big_buck_bunny.mp4, and it worked fine.

However I miserably failed trying to prepare my own video for streaming. I'm using FFmpeg & libx264 with the following line (last attempt):

ffmpeg -i <input> -c:v libx264 -profile:v baseline -c:a aac -strict experimental <output>

Then I passed the output to qt-faststart, as some people suggested... No effect.

Here is the output of ffmpeg -i for my video:

  • What exactly went wrong with the 1080p video? – Alex Cohn Dec 16 '13 at 23:58
  • The app reported with standard message "couldn't play the video". – Timofey Dec 17 '13 at 20:46
  • Which app? The built-in video player? That won't be surprising, but depends on device and ROM. – Alex Cohn Dec 17 '13 at 20:56
  • Yes, I think so. I test on HTC Desire S, if it matters. The app uses MediaController & VideoView. I pretty new into development for android and used this article as a guide: http://www.androidbegin.com/tutorial/android-video-streaming-videoview-tutorial/ – Timofey Dec 17 '13 at 23:58

    OK, so this is definitely the case. The fact that your device cannot play a 1080p baseline h264 stream is because ghe device manufacturer did not include such support. Other devices may play your stream even if their screens are ldss than 1080 pixels wide. – Alex Cohn Dec 18 '13 at 04:52
  • According to http://androidforums.com/htc-desire-s/341630-htc-desire-s-720p.html, your device can play 720p, even though the scree is only 800×480 – Alex Cohn Dec 18 '13 at 05:01
