I am using Azure Media Service to live stream an event. My source is a HD SDI feed being captured via an AJA Kona LHi card and sent to Azure using Wirecast.

I'm using the default settings in Wirecast for Azure Media Service. I am using standard encoding and the 720p preset. I am using the Azure Media Player embedded in a private site.

Everything seems to work however iOS devices are unable to AirPlay the stream. The video plays correctly on the device but no AirPlay controls are available.

If I use the exact same setup to stream my webcam the AirPlay controls are available. Is there some specific configuration required to make this work reliably?

Requirements: A video player that can play video created with multi-angle cameras. (To be implemented in application that provides multi-angle views for sports) The camera angle switch part must be smooth similar to u-switch player at:

http://1beyond.com/u-switch

Initial setup: videos captured by normal camera, wowza streaming server for VOD(The protocol being used is HLS), amazon servers to store files, i'm getting url to videos that need to streamed.

Approach 1:

• Save video files from diff camera angles as diff files and provide url to each of those.

eg. http://[wowza-server]/[application]/mp4:[file_name_camera1]/playlist.m3u8

http://[wowza-server]/[application]/mp4:[file_name_camera2]/playlist.m3u8

--In android application,load data from next camera view in same video view when next is clicked. Prob: The switching is not smooth.

--Load data in buffer in background while first camera view url is being played. Prob: Continuous increase in size of buffer as well as network bandwidth consumption which is waste in case the user never loads next camera url.

Approach 2:

-Create single video with multiple video and audio tracks for multiple camera angles.

The single video must be timecode-alligned(Requires specific hardware e.g: wirecast,u-switch encoder etc)

Prob:

Default media player as well as exoplayer doesn't provide support for changing video tracks. However, Exoplayer supports adaptive streaming by switching to diff quality tracks in the stream for DASH and HLS.

I'm looking for help to either modify the TrackRenderer class in Exoplayer to add support for multi track selection and switching or any other solution that fits to the current problem.

Single RTMP video message usually carries one H.264 frame together with the timestamp delta. Usually the timestamp delta represents the duration of the single video frame, eg. 40ms for 25FPS video. This allows to compute the duration of the stream by calculating the sum of the RTMP video deltas in stream.

However, for some encoders (e.g. Wirecast) there are occasionally RTMP video messages that contain just one H.264 frame but the timestamp delta is the multiple of the single video frame duration (e.g. 120ms, 160ms etc).

Does it mean that in some cases a single H.264 frame can represent multiple video frames? Which H.264 frame meta information (field) represents this?How to distinguish that for a selected frame the timestamp delta should be different from the the duration of a single video frame? I would like to correctly calculate the presentation timestamp for a single H.264 frame.

I´m trying to create a textfile that my ffmpeg-command can use to merge two videofiles. The problem I´m having is getting my folder/file-paths to look like I want. The two lines that cause my problems are:

set theFile to path to replay_folder & "ls.txt"

I simply want this path to be the path of replay_folder and ls.txt

In the shell script line I want the same thing.

do shell script "cd " & replay_folder & " /usr/local/bin/ffmpeg -f concat -i ls.txt -c copy merged.mov"

I get this path with the shell script Macintosh HD:Users:BjornFroberg:Documents:wirecast:Replay-2017-03-17-12_11-1489749062:

But I want this /Users/BjornFroberg/Documents/wirecast/Replay-2017-03-17-12_11-1489749062/

The full code is:

I´m broadcasting hockey with wirecast and use applescripts triggered by a usb-controller to create replays, highlights etc. I need as much as possible of what I´m doing to be automated as I am alone working with this witch means I´m also the cameraman :)

Now I want to be able to convert and upload a .gif of the last scored goal. So far I have been able to convert my .mov file to .gif but haven´t found a way to upload it to twitter.

The workflow is: when a team scores a goal I push a button on my usb-controller. This stops wirecast-recording, opens the recorded file in quicktime player 7, trims it down to the last 16 seconds and when that file is finished playing it saves as .mov and converts to .gif.

Here is where I run into trouble. I have been able to make twitter posts by using https://ifttt.com but it dosen´t seem to suport uploading .gif files. If I manually upload the .gif on twitter.com it works. What I need is to make it automated.

Anyone have ideas of how to do this? I´m pretty new to scripting and really appreciate any help :)
