m3u8: define segment parsing once

2025-05-20T05:51:19Z

commit a5e36fbfb60aadd58d7a06c29272251c0a8f8c0e parent 093b7480bc7275b0047361f2f87d3992bc71e5ee Author: Oliver Lowe Date: Tue, 20 May 2025 15:51:19 +1000 m3u8: define segment parsing once It's a bit of a hack that we read one item too many from the lexer. This change modifies segment parsing by sending the already consumed lexer items and subsequent lexer items back through another channel. Maintaining the original order through a channel means we can parse a segment in a single loop. Much shorter than dealing with the first item and all other items separately. This puts off looking into any redesigns of the lexer. For now...?

m3u8: clarify purpose of some sample playlists

2024-08-12T00:54:34Z

commit 7c79b0547941d5c8539ca8c8206cefdf0f4f74aa parent fa32a75741dba59c89d92757937ef9039129dea1 Author: Oliver Lowe Date: Mon, 12 Aug 2024 10:54:34 +1000 m3u8: clarify purpose of some sample playlists Big Buck Bunny is the classic test sample for a lot of video dev work. tos.m3u8 is here because it is a valid playlist containing lots of comments and empty lines. Unusual, but still a valid playlist; hoping it will help catch bugs in our parser's handling of comments and whitespace.

sdp: only apply TTL field to ipv4 connections

2024-08-11T03:46:08Z

commit fa32a75741dba59c89d92757937ef9039129dea1 parent 96a874b067dad9a5704171d9c63a5594b6d42e3d Author: Jacob Hitchins <44385069+jacobhitchins@users.noreply.github.com> Date: Sun, 11 Aug 2024 13:46:08 +1000 sdp: only apply TTL field to ipv4 connections As per section 5.7 of RFC 8866: "IP6" multicast does not use TTL scoping, and hence the TTL value MUST NOT be present for "IP6" multicast. Amends comment to clarify it only applies to IPv4 packets.

sdp: resolve remaining validation, documentation TODOs

2024-08-10T08:56:32Z

commit 96a874b067dad9a5704171d9c63a5594b6d42e3d parent 8d2c4bc42dfbbe01d8d7cfd968ca60c8048ae6f9 Author: Oliver Lowe Date: Sat, 10 Aug 2024 18:56:32 +1000 sdp: resolve remaining validation, documentation TODOs No real changes, just notes. Always encode a valid timestamp when session start time is unset but an end time is set. Document the TTL in ConnInfo is a specific property of multicast traffic. No need to impose more structure on session Attributes when the data is pretty free-form anyway (similar to http.Header). Safely round times in session repeat schedules to ensure we never write invalid decimal places.

This patch also correctly specifies and sets the payload size to always fits a UDP packet to fit in the typical network MTU of 1400-ish bytes. The sample rate and transmission interval are modified accordingly with guidance from RFC 3551.

Since this part of SDP is rarely - if ever - used in the wild, I'd rather have less code. While here don't bother with subtests; letting it all run one after the other is just as clear and less code. We're not doing parallel testing either.

sdp: manage parsing state in a parser struct

2024-07-05T06:51:16Z

commit 439c6395b12db4f7329a94e472639a5b55169cf0 parent baedec4c102a6e02db8236e10c2733080f2ba3e2 Author: Oliver Lowe Date: Fri, 5 Jul 2024 16:51:16 +1000 sdp: manage parsing state in a parser struct The ReadSession and readSession functions were getting pretty long, with break labels and even a goto. Managing the state in the parser obviates that stuff. It also let us deduplicate much of the scanning logic e.g. checking for empty/invalid lines.

sdp: Parse option media description fields

commit baedec4c102a6e02db8236e10c2733080f2ba3e2 parent c2edff6142980892930d56b4d97f7aa4a0650f4f Author: Oliver Lowe Date: Fri, 5 Jul 2024 15:41:47 +1000 sdp: Parse option media description fields The parsing logic has become pretty tricky! Tests pass, so refactoring can be done pretty safely as long as we still get the Session struct out that we expect.

sdp: handle parsing connection info

commit c2edff6142980892930d56b4d97f7aa4a0650f4f parent 0da91c7d665bcbadeb67e22762a4bcb818e1ca4f Author: Oliver Lowe Date: Fri, 5 Jul 2024 14:12:36 +1000 sdp: handle parsing connection info This is not stored in the Session struct yet. The parsing code feels untidy, but we can come back to that later. We have tests so it should be easy enough to refactor.
