[gst-devel] some issues when trying to save content to disk during http progressive downloaded

[Zhao, Halley]

Thanks.

I understand that there are possible headers at the START or the END, however my question is about the saved contents, not playback itself during progressive downloaded.

If I don't add a tee and filesink to save the content, all my mentioned contents can playback in progressive downloaded well.

Especially for the mp4 contents mentioned, files are different (even file size) between save during playback and save directly from souphttpsrc:
gst-launch-0.10 souphttpsrc location=http:// 10.238.37.11/share/media/video/test.mp4 ! tee name=t ! decodebin ! ffmpegcolorspace ! xvimagesink t. ! queue ! filesink location=test.mp4

gst-launch-0.10 souphttpsrc location=http:// 10.238.37.11/share/media/video/test.mp4 ! filesink location=/home/halley/swap/streaming/test2.mp4

I suspect soup request header at the END of the mp4 file when playback starts, but this header isn't save to file by filesink.

What you describe sounds like what's expected.

True streaming formats (like ogg) work fine.

Formats that may have the headers at the start OR the end vary - some
have the headers at the end, so they're not playable until you've
downloaded the entire file. Some have them at the start, so
progressive download/playback works.

This doesn't have anything to do specifically with GStreamer, it's
simply how the formats work.
