Highwinds: siging/smil and bitrate switching/smil working?

[jeroen]

Seems like both combinations of methods don't cooperate at present. Let's figure out...

[jeroen]

Signing of FMS SMIL files doesn't work with Highwinds anyway, so skipping this one...

The doppler parameters seem to be including the rtmp source for building the sig. Hence, with bitrate switching the smil file always has to be re-requested and the server always has to be re-connected. Hard to do...

• rtmp://stream. [stp] .com/simplevideostreaming/
• Wowza 1.72

When I connect this is the typical thing:

INFO stream play /wp-content/uploads/Sports/Rollins/Soccer/womens/09/ RWSOCVsFloridaSouthern09_928k_w608.mp4 - latency: 52.0 INFO server comment - onBWDone: 3154.0 latency: 48.0 INFO server comment - onBWDone: 3423.0 latency: 52.0 INFO server comment - onBWDone: 2531.0

I was the only viewer. Tests happen every 10-15 seconds. Tests continue after the video ends.

Two changes need to be made to fix both issues:

1. If SMIL redirects are used, dynamic streaming should be discarded.
2. If a Wowza/FMS3 server is used, the bandwidth should only be checked once - on startup.

Issue 2 has indeed been fixed by only doing a single check.

Issue 1 fixed as well, by making two changes:

• If SMIL redirects are used, dynamic streaming should be discarded.
• If SMIL redirects are used and bitrates are switched, the smil should be requested again.
