James Almer	66c05dc031	avformat/iamf_parse: ignore Audio Elements with an unsupported type Better fix for the NULL pointer dereference from `d7f83fc2f4`. Signed-off-by: James Almer <jamrial@gmail.com>	5 months ago

Andreas Rheinhardt	4a4dcde339	avformat/internal: Move FF_FMT_INIT_CLEANUP to demux.h and rename it to FF_INFMT_INIT_CLEANUP. This flag is demuxer-only, so this is the more appropriate place for it. This does not preclude adding internal flags common to both demuxer and muxer in the future. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	10 months ago
Andreas Rheinhardt	b800327f4c	avformat/avformat: Add FFInputFormat, hide internals of AVInputFormat This commit does for AVInputFormat what commit `59c9dc82f4` did for AVOutputFormat: It adds a new type FFInputFormat, moves all the internals of AVInputFormat to it and adds a now reduced AVInputFormat as first member. This does not affect/improve extensibility of both public or private fields for demuxers (it is still a mess due to lavd). This is possible since `50f34172e0` (which removed the last usage of an internal field of AVInputFormat in fftools). (Hint: tools/probetest.c accesses the internals of FFInputFormat as well, but given that it is a testing tool this is not considered a problem.)

James Almer	80131321c4	avformat/iamfdec: set disposition flags to output streams if there's an audio layer with a single stream that can be rendered alone, mark it as default. Otherwise, mark every stream as dependent. Signed-off-by: James Almer <jamrial@gmail.com>	11 months ago
James Almer	c7266ad60f	avformat/iamfdec: further split into shareable modules Signed-off-by: James Almer <jamrial@gmail.com>	11 months ago
Andreas Rheinhardt	18af922c53	avformat/iamf: Don't mix ownership and non-ownership pointers 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.
