Could you please post the URI of one of the trailers you have problems
with? What's the output of

gst-inspect-0.10 playbin | grep Version

?

Cheers

This plays fine for me if I ommit the queue sizes. Can you explain why you like
to set them?

Re: Buffering with playbin

Hi Stefan,
I wanted to increase the buffer sizes so that when streaming large content, it doesn't keep buffering every 2-3 seconds. That makes the streaming movie unwatchable. I rather have it wait a longer period and buffer up around 15 seconds of video before playing. On your side, does it hang at buffering when having a queue size?

I see. I can confirm that it hangs (38% for me). Although it works when I ommit
the queue-threshold. I am not sure what playbins queue-threshold actually means,
for me its looks like it won't go on until that is reached.

Re: Buffering with playbin

It seems that if the queue-threshold isnt specified and just the queue-size is, that the buffering rate doesn't change at all. Basically I guess without changing the threshold, having a bigger buffer won't do anything. I still don't understand why it hangs when changing queue-size.

Buffering with playbin

In reply to this post by Stefan Sauer

I've set queue-threshold and queue-size properties of playbin to around 9 seconds, and I noticed during buffering streaming content, it hangs at a certain percentage. This happens on totem and gst-launch for an apple quicktime movie trailer. I've tried changing this number several times (even the default), but the hang still happens. Is there a reason this is happening or something I am missing?

For example,
gst-launch -m playbin uri="http://movies.apple.com/movies/wb/the_dark_knight/the_dark_knight-tlr2_h1080p.mov" queue-size=50000000000 queue-threshold=9000000000

Is there any other way to increase buffer size of streaming movies via playbin?

Get Windows Live and get whatever you need, wherever you are. Start here.

I'm just guessing, but qtdemux has an initial phase where it parses the headers of the mov file, maybe it is related to this.

For example,
gst-launch -m playbin uri="http://movies.apple.com/movies/wb/the_dark_knight/the_dark_knight-tlr2_h1080p.mov" queue-size=50000000000 queue-threshold=9000000000

Is there any other way to increase buffer size of streaming movies via playbin?

Re: Buffering with playbin

It seems to happen when other media types as well. I've tested mpeg2 and wmv. Any other ideas?

I've set queue-threshold and queue-size properties of playbin to around 9 seconds, and I noticed during buffering streaming content, it hangs at a certain percentage. This happens on totem and gst-launch for an apple quicktime movie trailer. I've tried changing this number several times (even the default), but the hang still happens. Is there a reason this is happening or something I am missing?
