Christopher Usher	fe5b10f86b	Fixes the state transitions of the trimbleshim to allow video links to be changed or removed	5 years ago
Mike Lang	5c84e8dfab	restreamer: Fix wrong name for parse function ... derp	5 years ago
Mike Lang	cca4d52b7d	Don't error when encountering a temp-type segment ... These can happen if a downloader or backfiller dies suddenly. We treat it similarly to partial but lacking any hash. At some point in the future we should probably have something to find any temp segments, hash them and rename them to partials.	5 years ago
Mike Lang	f8d10dacdf	Audit and fix all usage of dateutil ... We wrap direct dateutil calls to handle two distinct cases: * `common.dateutil.parse()`: We want to handle arbitrary timestamps including tz info, then convert them to UTC. This is used in HLS parsing, and for command line input for backfiller * `common.dateutil.parse_utc_only()`: We want to only handle UTC timestamps, but datetime.strptime isn't flexible enough (eg. can't handle missing fractional component). This is used for restreamer request params.	5 years ago
Mike Lang	5b2a1ef6b7	cutter: Implement actual cut methods ... Each method is fairly complicated, but is self-contained and can be examined independently. cut_jobs in particular contains several extra helpers and directs control flow via some iterators. This is unfortunately nessecary due to the requests interface.	6 years ago
Mike Lang	ae809c696c	cutter: Outline of how main cutter run loop works ... This commit only lays out the main loop, showing the high-level flow and defining shared utilities. This is for clarity. The actual methods that do the work will be implemented seperately.	6 years ago
Mike Lang	80c1a66aa0	cutter: Implement TranscodeChecker ... It runs on an interval, fetching all videos in TRANSCODING from the DB, checking them against youtube, and then updating any that are done. It should be noted that youtube somewhat lies about what being "done" means, but this is a better approximation than nothing.	6 years ago
Mike Lang	3ce8360a1e	cutter: Add database manager and connections ... One connection each for transcode checker and cutter. We don't need more than one each since both workers only ever do one thing at once.	6 years ago
Mike Lang	fdd245a6d9	cutter: Add lightweight youtube client ... Provides basic youtube api calls, and gets passed into both transcode checker and cutter. The official youtube client library is many orders of magnitude larger and more complicated, and can't actually do what we want (stream an upload of unknown size).	6 years ago
Mike Lang	dfc64481a6	Port existing cutting code from restreamer into common ... Note this moves over the 'experimental' cutter and deletes the original cutter that concatenates entire videos before cutting. We may eventually want to revive that method if the experimental cutter turns out to introduce too many issues. We move most of the code over verbatim, but adjust it such that it acts as a generic iterator that can be used in a variety of contexts. Some other changes made during the move include telling ffmpeg to be quieter (don't output version info and junk, only log if something goes wrong), and avoiding errors during cleanup.	6 years ago
Mike Lang	3d9ba77745	common: add allow_holes option to get_best_segments() to abort early if holes found ... This is a performance optimization, allowing us to fail out early (potentially avoiding a LOT of work) if we know we're going to reject any result that contains holes. We add a new exception ContainsHoles that is raised in this condition.	6 years ago
Mike Lang	e4b6110fd7	cutter: Add initial outline ... The cutter has two jobs: * To cut videos, taking them through states EDITED -> TRANSCODING * To monitor TRANSCODING videos for when they're complete We run these as separate greenlets with their own DB connections, and if either dies we gracefully shut down the other.	6 years ago
Christopher Usher	f43c699e05	updated thrimshim to handle all non-null edit columns	6 years ago
Mike Lang	e383613954	database: Add constraints on edit inputs that they must be non-NULL if state != UNEDITED ... This should help prevent changing state to EDITED with any of these fields unset, which would blow up the cutter. We also fix up upload_location, which was set up as a sheet input (NOT NULL DEFAULT ''), and add a similar constraint saying any DONE columns must have non-NULL video link.	6 years ago

Mike Lang	292188ad7c	database: Remove retry_on_conflict helper and default to autocommit ... All our usage was of a single query anyway, so autocommit is easier to handle. You can still opt into a longer transaction using the transaction() helper.	6 years ago
