I have pre-recorded opus and vp8 files. In a webrtc call I am trying to stream audio / video to chrome.
While audio is played in chrome, but it fails to show video.
I read from google search that first video frame I need to send as i-frame. I am bit new to video stuff. Can somebody help me to learn how to send a i-frame in case of video.
Can there be other potential issues, why chrome does not like video frames. Please note that ICE and Dtls handshake goes well.

I am developing a pair of websites (podyplomie.pl and magwet.pl).
On both of them we have added a video player (JWPlayer).
I am almost sure flash player on both of them was working in the beginnig but now I can play the video (in flash) only on one of the sites (podyplomie.pl).
The other site is missing flash player in the list of navigator.plugins. Both sites are very similar so it's quite strange that one of them 'contains' the flash player and the second doesn't.
Has anyone got an idea what is wrong ?
The video urls are eg:
Video on magwet.pl
Video on podyplomie.pl
You don't have any Flash video (.FLV). Your videos are in .MP4 format. Chrome browser can play MP4 with it's own decoding engine (no need for plugins like Flash). JW Player is seeing MP4 given as video source so it talks to browser not plugin...
PS: To force Flash plugin usage then provide an .flv file or rtmp:// link.
This MPEG-DASH stream
http://54.241.9.147/new-fandor/vod/21/2157/dark_star_FILM_v11.smil/manifest_mpm4sav_mvlist.mpd
doesn't play in dash.js -- it plays the first segment at the lowest bitrate, switches to the next higher bitrate and stops after loading the second bitrate's init information. You can see this by pointing Chrome at the dash.js reference player, entering the stream URL in the top box and hitting Load. Open the JavaScript console to see that dash.js reported a media error, which means that the video element had a .error.
The same player is able to play this stream in IE11 without error.
These streams, each of which contains only one of the bitrates that play in the above sequence, both play without error in Chrome, so it's not that the underlying media is just somehow corrupt.

Any ideas?
A Chromium person says that this is due to audio sample rate switching, which Chrome doesn't support yet: https://code.google.com/p/chromium/issues/detail?id=315330 Although each of our videos' video bitrates should have had the same audio bitrate, some videos had different audio bitrates for different video bitrates. The solution was to reencode those videos correctly.
So I did a little searching about the whole issue with HTML5 video tag etc. My client doesnt want the videos to be played through FLASH and general youtube. So he wants a custom video player and we should upload the video files to our server.
I have a problem displaying the video in Google Chrome why is that? http://www.2kfilms.com/jw_test2.html
In the above link you can see that it displays normally in IE. I found out that the best encoding you should have with HTML5 is: H.264 *OGG* and WEBM
So if I have the 3 different formats will it also play in Chrome?
Even this video here: http://www.w3schools.com/tags/tryit.asp?filename=tryhtml5_video
doesnt play in my Google Chrome, and I find it weird. Its black and I can only hear Audio
Can I click on some time and eventhough the video is not downlaoded till that time and the video starts playing from the time I clicked?
If yes, what would be a better option for viewing streamed video- HTML5 or flash player like JW player? WHich one will have less lag?
HTML5 browsers generally don't support this, however I believe the video tag in Safari will work with the Apple HTTP Streaming format for this functionality. For something that works across all browsers, Flash Player can do it using either RTMP streaming or HTTP Streaming (either with our without OSMF to support this). Probably the easiest place to start is with OSMF, which supports both RTMP and HTTP streaming of video.
I have tested this with Firefox and Firebug and while you can "seek" to a point in the video without having to watch video preceding the point you wish to seek, this still causes the entire video file to download.
Indeed, each time you seek in Firefox 4, the entire video downloads.
This may change and improve as HTML 5 video implementations become more mature and may differ based on the actual browser being used.

i have an icecast server serving continuous mp3 stream. i tried to play it in html5 with the audio tag. in safari it shows up and plays, but the moment the song changes, the stream stops and will not start again, even it i press the play button.
does anybody know a way around this?
This is a known Firefox Bug “Firefox fails on chained ogg stream” #455165 and should be fixed in Firefox 20.
Update: Sorry, didn't saw that you said you are streaming mp3. Firefox might have similar issues with mp3 too…
