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

[Zhao, H. <hal...@in...>]

Thanks Stefan.
After add a 'queue' after 'souphttpsrc' and use 'decodebin2'; I still got same result.

I think the possible solution is to enhance souphttpsrc to save content to disk after some refractor, because souphttpsrc does some seek following the command of parser.

Attached mp4.log is the log of souphttpsrc, it seek to the end of the mp4 file at the beginning of playback. Finally, tail of the original mp4 file is missing in downloaded mp4 file.

At first use decodebin2!

If the http source is seekable, the muxer in decodebin will do pull. You could try:

gst-launch-0.10 souphttpsrc
location=http://10.238.37.11/share/media/video/test.mp4 ! queue ! tee name=t !
decodebin2 ! ffmpegcolorspace ! xvimagesink t. ! queue ! filesink location=test.mp4
