* av-merge: Use .shift() instead of .pop() in appendQueue for FIFOJames Taylor2021-08-311-1/+1
| | | | | | | .pop() gives LIFO, but FIFO was the intention for appendQueue. O(n) behavior is fine because appendQueue should be very small. Signed-off-by: Jesús <heckyel@hyperbola.info>
* av-merge: Fix handling of QuotaExceededErrorJames Taylor2021-08-311-15/+75
| | | | | | | | | | | | | | Many things fixed: - Delete from end of video in addition to from beginning. Firefox automatically deletes from the beginning already. - Increment i in the while loop (oops) - Calling .remove takes time for the sourceBuffer to perform, and it will be in the updating=true state. Continuing to delete more would give an error. Waits until the updateend event is fired before deleting more segments. - Retry appendBuffer if the quota was exceeded during a seek append Signed-off-by: Jesús <heckyel@hyperbola.info>
* av-merge: Fix numDeleted not incremented during segment deletionJames Taylor2021-08-291-0/+1

* av-merge: Fix malformed mp4 fragments wrongly considered deletedJames Taylor2021-08-291-1/+32
| | | | | | | | See comment within. They would be constantly rerequested and av-merge would think it didn't have them, so it wouldn't request subsequent segments Signed-off-by: Jesús <heckyel@hyperbola.info>
* av-merge: print sourceBuffer.buffered in printDebuggingInfoJames Taylor2021-08-291-0/+7

* av-merge: Fix error when switching qualities after endOfStreamJames Taylor2021-08-291-3/+5
| | | | | | | | | After the video has been buffered to the end and mediaSource.endOfStream() has been called, the close function would perform some closing operations on the sourceBuffers that gave InvalidStateError Signed-off-by: Jesús <heckyel@hyperbola.info>
* av-merge: Add function to dump debugging infoJames Taylor2021-08-291-1/+12

* av-merge: Use tickEnd+1 when calculating segment time rangesJames Taylor2021-08-291-4/+5
| | | | | | | | | | | | | | | | | | | | | | tickEnd is inclusive, so two segments might have the following ticks: -- Segment 0 -- tickStart: 0 tickEnd: 44099 -- Segment 1 -- tickStart: 44100 tickEnd: 88199 When doing calculations in seconds about segment extent, there were gaps between segment 0's end and segment 1's beginning. This sometimes resulted in errors of not finding the corresponding segment index inside these gaps. Using (tickEnd+1)/this.sidx.timeScale is the correct method.

* av-merge: End stream correctly when last segments do not overlapJames Taylor2021-08-291-3/+2
| | | | | | | | | | | | In this video at 480p: https://www.youtube.com/watch?v=6bnanI9jXps There is an extremely tiny audio segment from 30.00018140589569 to 30.06981859410431 after the last video segment ends at 29.99998888888889. Call end of stream when we have all segments until the end, instead of calling it when we are playing the last segment. Signed-off-by: Jesús <heckyel@hyperbola.info>
* watch.html: Move loose inline javascript into watch.jsJesús2021-08-291-7/+0
| | | | | | | | The number of inline code blocks and the dependencies between them became unmanageable. From 9d96c07a3c2e68f1893634574c3be64e41a2c041 Mon Sep 17 00:00:00 2001 From: James Taylor <user234683@users.noreply.github.com>

* avmerge: Fix errors if close is called twiceJames Taylor2021-08-291-0/+4
| | | | | | | | | | | This can happen if the quality is changed from an avmerge source to an integrated source, and then changed back to an avmerge source Close is called the first change, but on the last change, it's called again because the avMerge object is still present, resulting in InvalidStateError Signed-off-by: Jesús <heckyel@hyperbola.info>
* avmerge: Remove obsolete shouldFetchNextSegment functionJames Taylor2021-08-291-9/+0

* avmerge: Close streams to avoid errors while changing qualityJames Taylor2021-08-291-8/+39
| | | | | | | | | | | | | If a fetchRange network request finished after the quality was changed, there would be a "InvalidStateError: An attempt was made to use an object that is not, or is no longer, usable" because appendSegment was trying to append to the sourceBuffer that was unusable after the video src was changed to a new mediaSource. Adds a close method to the AVMerge class to properly clean and close everything so these sorts of errors won't happen. Signed-off-by: Jesús <heckyel@hyperbola.info>
