popcornmix	def56677e5	wtv: Speed up wtv index creation The index creation is O(N^2) with number of entries (typically thousands). On a Pi this can take more than 60 seconds to execute for a recording of a few hours. By replacing with an O(N) loop, this takes virtually zero time Liked-by: Paul B Mahol <onemda@gmail.com> Reviewed-by: Peter Ross <pross@xvid.org> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago

Reimar Döffinger	dddd006cab	wtvdec: set correct codec ID for CC streams. Closed caption data is definitely not teletext. Since it contains a EIA-608 compatibility stream, the EIA_608 codec ID is at least not completely wrong. Fixes subtitle playback in MPlayer with the sample in trac ticket #1482. To fix the ticket itself I expect FFmpeg will need a closed-caption to SRT decoder first. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	13 years ago
