After contacting the original author of the the patch posted in:
http://lists.ffmpeg.org/pipermail/ffmpeg-devel/2014-February/154612.html
I attach a new patch with improvements:
- Better codec detection in amfmetata
- Better live streams handling (Get current segment, calculate next
segment..etc)
- Parse tabs in raw xml (0x09)
Tested streams:
http://livehds.rasset.ie/hds-live/_definst_/rte1/rte1_288p.f4m
http://livehds.rasset.ie/hds-live/_definst_/rte2/rte2_288p.f4m
http://livehds.rasset.ie/hds-live/_definst_/newsnow/newsnow_288p.f4m
TODO:
- Parse child manifest, ex:
http://www.rte.ie/manifests/rte1.f4m
http://www.rte.ie/manifests/newsnow.f4m
- Implement fragment caching.
