Comment (by Jiri Fojtasek <jiri.fojtasek@…>):
This is v2 of the patch. It fixing issues from previous version:
- Internalreadpos in ringbuffer not always follow real position in the
file, so it was replaced by seek() to always get correct position.
Improvements:
- Leave portion of the file in pagecache because livetv playback may need
it very soon. This will reduce disk io during livetv playback and decrease
time required to open next file when player switching/jumping to next
program. The size of may_need has been choosed as 5 seconds of 35mbit
playback.
