Mike Lang	6bf709287a	cutter: Introduce an alternate cutting approach that is much faster ... This cutter works by only cutting the first and last segments to size, then concatting them with the other segments, so we only ever process a few seconds of video instead of the entire video duration. However, to make this work, care must be taken that the cut segments use the same codecs as the other segments. The reason it's experimental is that we are not yet confident in its ability to cut accurately and without sync issues. We have seen some minor issues when trying to play back the raw output files, but youtube's re-encoding has consistently smoothed out those issues and they seem to be highly player-specific. Vigorous testing is needed. Also note that both methods right now (cat then cut, and cut then cat) only work if all the segments are cattable, that is they all use the same codecs, have the same resolution, etc. If a stream were to change its encoding settings, and we were cutting over that change, both approaches would not work. We should add checks for that scenario (which can only happen over a stream drop), and if so fallback to a slow method using ffmpeg's concat filter, which will work even for disparate codecs, though reconciling mismatched resolutions or frame rates may require further work.	6 years ago
Mike Lang	18aadd6b82	restreamer: Also have an endpoint for generating cut videos on demand ... This is mainly just for testing until we get the database and proper cutter up, but it might prove useful to have in the long run too. This code will probably end up being totally rewritten, as it uses the most naive form of cutting and reencoding, and it has a whole bunch of http-serving specifics intertwined with the cutting logic.	6 years ago

Mike Lang	b4e627f382	restreamer: When generating playlists, include discontinuities, timestamps and endlist ... This fills out the incomplete playlist generation functionality to handle holes and communicate extra information. See comments for details.	6 years ago

Mike Lang	8f5a98a906	restreamer: Don't offer a variant on the master playlist if it's outside requested time range ... This prevents clients from picking a variant that they then can't play any content for. In general we expect the same content to be available on all variants being captured, but if the set of captured variants changes we still want to handle that gracefully.	6 years ago
