* Revert "avformat/mov: zero initialize the index ranges buffer"Andreas Rheinhardt2024-02-27
| | | | | | | | | | | | This reverts commit eee3b7e2fb0664b889e58c03f76e19ef23e4d1d8. It has been made in an attempt to fix UBSan test failures with GCC 13 (see e.g. [1]), but it did not help at all. So revert it, but use av_malloc_array() instead of going back to av_malloc().

* flvdec: Honor the "flv_metadata" option for the "datastream" metadata fieldMartin Storsjö2024-02-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | By default the option "flv_metadata" (internally using the field name "trust_metadata") is set to 0, meaning that we don't allocate streams based on information in the metadata, only based on actual streams we encounter. However the "datastream" metadata field still would allocate a subtitle stream. When muxing, the "datastream" field is added if either a data stream or subtitle stream is present - but the same metadata field is used to preemtively create a subtitle stream only. Thus, if the field was added due to a data stream, not a subtitle stream, the demuxer would create a stream which won't get any actual packets. If there was such an extra, empty subtitle stream, running avformat_find_stream_info still used to terminate within reasonable time before 3749eede66c3774799766b1f246afae8a6ffc9bb. After that commit, it no longer would terminate until it reaches the max analyze duration, which is 90 seconds for flv streams (see e6a084641aada7a2e4672172f2ee26642800a361, 24fdf7334d2bb9aab0abdbc878b8ae51eb57c86b and f58e011a1f30332ba824c155078ca701e29aef63). Before that commit (which removed the deprecated AVStream.codec), the "st->codecpar->codec_id = AV_CODEC_ID_TEXT", set within the demuxer, would get propagated into st->codec->codec_id by numerous avcodec_parameters_to_context(st->codec, st->codecpar), then further into st->internal->avctx->codec_id by update_stream_avctx within read_frame_internal in libavformat/utils.c (demux.c these days).

* avformat/iamf: Don't mix ownership and non-ownership pointersAndreas Rheinhardt2024-02-19
| | | | | | | | | | | | | | | | | | | | | | | | | IAMFAudioElement and IAMFMixPresentation currently contain pointers to independently allocated objects that are sometimes owned by said structures and sometimes not. More precisely, upon success the demuxer transfers ownership of these other objects newly created AVStreamGroups, but it keeps its pointers. iamf_read_close() therefore always resets these pointers (because the cleanup code always treats them as ownership pointers). This leads to memory leaks in case iamf_read_header() without having attached all of these objects to stream groups. The muxer has a similar issue: It also clears these pointers (pointing to objects owned by stream groups created by the user) in its deinit function. This commit fixes this memleak by explicitly adding non-ownership pointers; this also allows to remove the code to reset the ownership pointers.

| | | | | | | | | | | | Previously, we produced output with either \r\n or mixed line endings. This was undesirable unto itself, but also made working with patches affecting FATE output particularly challenging, especially via the mailing list. Everything that consumes the SSA/ASS format is line-ending-agnostic, so \n is selected to simplify git/ML usage in FATE. Extra \r characters at the end of a packet are dropped. These are always ignored by the renderer anyway.

* avformat/mov_chan: never override number of channels based on chan atomMarton Balint2024-02-09
| | | | | | | | | | | The channel designation metadata should not override the number of channels. Let's warn the user if it is inconsistent, and keep the channel layout unspecified. Before the conversion to the channel layout API the code only set the mask, but never overridden the channel count, so this restores the old behaviour. Signed-off-by: Marton Balint <cus@passwd.hu>

| | | | | | | | | | Existing code could have caused wrong channel order signalling or reduced channel count if a channel designation appeared multiple times.

* avformat/rcwtenc: Fix potential out-of-bounds writeAndreas Rheinhardt2024-02-09
| | | | | | | | | | | | | | | | | | The rcwt muxer uses several counters for how much data it has already cached: One byte counter and one counter for how many complete blocks (of three bytes each). These counters can become inconsistent when the muxer is fed incomplete blocks as the muxer presumes that it is about to write a new block at the start of each write_packet call. E.g. sending 65535*3+1 1-byte packets (with data[0] e.g. 0x03) will trigger an out-of-bounds write. This patch fixes this by processing the data in complete blocks only. This also allows to simplify the code, e.g. to remove one of the counters. Reviewed-by: Marth64 <marth64@proxyid.net> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
