* avformat/rtpdec: int overflow in start_time_realtimeJonathan Baudanza2025-01-101-1/+1
| | | | | | | | | | | | | | | | | | | | This was previously adjusted by me in 6b3f9c2e92b. Unfortunately, I traded one integer overflow bug for another. Currently, NTP timestamps that exceed INT64_MAX (~Jan 20, 1968) will cause an overflow when passed to av_rescale. This patch replaces av_rescale, which operates on int64_t, with ff_parse_ntp_time, which operates on uint64_t. This will give the correct values for timestamps back around the NTP epoch and present day timestamps. Fixes ticket #11388. Signed-off-by: Martin Storsjö <martin@martin.st>

* avformat/flvenc: fix missing sequence start with MP3 tracksAlessandro Ros2025-01-071-0/+1
| | | | | | | | | | | | | When muxing to FLV/RTMP a MP3 track with an ID greater than zero, enhanced RTMP has to be used, and a sequence start should preceed track data. This is already implemented (see line 823 of flvenc.c) but the code is never reached due to a too-strict condition before it. This patch fixes the issue.

* avformat/iamfdec: swap back and side streams if both are presentJames Almer2025-01-032-2/+24
| | | | | | | | | | | | Layouts with both pairs (7.1, 7.1.2, etc) in IAMF that follow the definition in ITU-R BS.2051-3 for Systems I and J also follow its ordering. This means side comes before back, which is the inverse of how it's defined in AVChannel. To workaround this without having to use custom order channel layouts, swap the stream ids in the input IAMF structure, so packets for one are mapped to the other.

| | | | | | | | | | | | | Based on enhanced-rtmp v2 spec published by Veovera: https://veovera.github.io/enhanced-rtmp/docs/enhanced/enhanced-rtmp-v2 This implementation maintains some backwards compatibility by only writing the track information for track indices > 0. This means that older FFmpeg versions - and possibly other software - can still read the first video track properly and skip over unsupported packets.
