Víctor Manuel Jáquez Leal	64cb38685b	matroskademux: Handle element's duration query. ... This is small regression from commit f7abd81a. When calling `gst_element_query()` no pad is associated with that query, but the current code always forwards the query to the associated pad, which is NULL in previous case. This patch checks for the pad before forwarding the query. Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/3404>	2022-11-14 15:10:44 +00:00
Thibault Saunier	f7abd81a45	matroskademux: Let upstream handle seeking/duration query in time if possible ... So proper response are given for dash streams Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/3159>	2022-10-27 19:45:44 +00:00
Thibault Saunier	8c7579e129	matroskademux: Start support for upstream segments in TIME format ... So we can use matroskademux for dash webm dash streams. Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/3159>	2022-10-27 19:45:44 +00:00
Sebastian Dröge	cf887f1b8e	matroskademux: Avoid integer-overflow resulting in heap corruption in WavPack header handling code ... blocksize + WAVPACK4_HEADER_SIZE might overflow gsize, which then results in allocating a very small buffer. Into that buffer blocksize data is memcpy'd later which then causes out of bound writes and can potentially lead to anything from crashes to remote code execution. Thanks to Adam Doupe for analyzing and reporting the issue. CVE: CVE-2022-1920 https://gstreamer.freedesktop.org/security/sa-2022-0004.html Fixes https://gitlab.freedesktop.org/gstreamer/gstreamer/-/issues/1226 Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/2612>	2022-06-15 18:35:12 +00:00
Nicolas Dufresne	0f15580853	matroska: Fix AV1 alignment to TU ... Matroska stores AV1 in temporal unit, so that all OBU sharing the same timestamp are put together. This was previously just assumed, which isn't safe now that we have more alignments. Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/1837>	2022-03-04 21:58:15 +00:00
Jan Schmidt	7efdc9c7f5	matroskademux: Don't parse Tracks element twice ... If the tracks element was parsed from the SeekEntry, don't parse it a second time and recreate tracks, as this loses any tags that were read using the seek table. If a genuinely new Tracks element is found, do read that as it is needed for MSE support.

Nirbheek Chauhan	4e22ef5bd2	matroska-demux: Emit a warning when no codec data found ... It is bad if an mkv file does not have codec data for the ProRes variant, so we should emit a warning. ffmpeg does the same thing.

Sebastian Wick	e61e069189	matroska: default prores fourcc apcn ... If there is no codec private data for prores it should default to Apple ProRes 422 Standard Definition (apcn). Can be tested with strobe_scientist.mkv from https://developers.google.com/media/vp9/hdr-encoding Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/1734>	2022-02-18 08:38:31 +00:00
Rafał Dzięgiel	41385ab6f7	matroska: Ref index table when updating track info ... Track index table array was being lost during track info update. Ref it over to updated info, so it can be used for finding nearest seek points. Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/1203>	2021-11-12 12:28:40 +00:00
Rafał Dzięgiel	478f94edc7	matroska: Use g_array_unref everywhere ... Instead of using g_array_free which is not thread safe use g_array_unref instead Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/1203>	2021-11-12 12:28:40 +00:00
