* avcodec/vvc/refs: remove early returnMarvin Scholz2025-06-281-3/+2
| | | | | | | | | | | | | The ret value is checked later on again, so this check is redundant and would cause the frame to not be unrefd on failure as well.

* avformat/tee: fix multiple bsfs in teeMarvin Scholz2025-06-261-1/+1
| | | | | | | | | | | | | Since 155508c6e925f4f2f5e77087a7e1925b3de735ff specifying multiple bsfs for different streams was broken: "[bsfs/a=h264_metadata:bsfs/v=h264_metadata]out.mp4|..." This incorrectly only parsed the first bsfs specification. The reason for this is that the dictionary is modified in the iterator, hence invalidating the iterator. The simplest fix for this is to simply iterate from the beginning in each loop given that the previous entry is removed.

For example, an audio element may have six coded streams in the form of two stereo streams, followed by two mono streams, and then by another two stereo streams, for a total of 10 channels, and define for them four scalable layers with loudspeaker_layout values "Stereo", "5.1ch", "5.1.2ch", and "5.1.4ch". The first layer references the first stream, and each following layer will reference all previous streams plus extra ones. In this case, the "5.1ch" layer will reference four streams (the first two stereo and the two mono) to encompass six channels, which does not match out native layout 5.1(side) given that FC and LFE come after FL+FR but before SL+SR, and here, they are at the end. For this reason, we need to build Custom order layouts that properly represent what we're exporting. ---- Before: Stream group #0:0[0x12c]: IAMF Audio Element: Layer 0: stereo Stream #0:0[0x0]: Audio: opus, 48000 Hz, stereo, fltp (default) Layer 1: 5.1(side) Stream #0:0[0x0]: Audio: opus, 48000 Hz, stereo, fltp (default) Stream #0:1[0x1]: Audio: opus, 48000 Hz, stereo, fltp (dependent) Stream #0:2[0x2]: Audio: opus, 48000 Hz, mono, fltp (dependent) Stream #0:3[0x3]: Audio: opus, 48000 Hz, mono, fltp (dependent) Layer 2: 5.1.2 Stream #0:0[0x0]: Audio: opus, 48000 Hz, stereo, fltp (default) Stream #0:1[0x1]: Audio: opus, 48000 Hz, stereo, fltp (dependent) Stream #0:2[0x2]: Audio: opus, 48000 Hz, mono, fltp (dependent) Stream #0:3[0x3]: Audio: opus, 48000 Hz, mono, fltp (dependent) Stream #0:4[0x4]: Audio: opus, 48000 Hz, stereo, fltp (dependent) Layer 3: 5.1.4 Stream #0:0[0x0]: Audio: opus, 48000 Hz, stereo, fltp (default) Stream #0:1[0x1]: Audio: opus, 48000 Hz, stereo, fltp (dependent) Stream #0:2[0x2]: Audio: opus, 48000 Hz, mono, fltp (dependent) Stream #0:3[0x3]: Audio: opus, 48000 Hz, mono, fltp (dependent) Stream #0:4[0x4]: Audio: opus, 48000 Hz, stereo, fltp (dependent) Stream #0:5[0x5]: Audio: opus, 48000 Hz, stereo, fltp (dependent) ---- AFter: Stream group #0:0[0x12c]: IAMF Audio Element: Layer 0: stereo Stream #0:0[0x0]: Audio: opus, 48000 Hz, stereo, fltp (default) Layer 1: 6 channels (FL+FR+SL+SR+FC+LFE) Stream #0:0[0x0]: Audio: opus, 48000 Hz, stereo, fltp (default) Stream #0:1[0x1]: Audio: opus, 48000 Hz, stereo, fltp (dependent) Stream #0:2[0x2]: Audio: opus, 48000 Hz, mono, fltp (dependent) Stream #0:3[0x3]: Audio: opus, 48000 Hz, mono, fltp (dependent) Layer 2: 8 channels (FL+FR+SL+SR+FC+LFE+TFL+TFR) Stream #0:0[0x0]: Audio: opus, 48000 Hz, stereo, fltp (default) Stream #0:1[0x1]: Audio: opus, 48000 Hz, stereo, fltp (dependent) Stream #0:2[0x2]: Audio: opus, 48000 Hz, mono, fltp (dependent) Stream #0:3[0x3]: Audio: opus, 48000 Hz, mono, fltp (dependent) Stream #0:4[0x4]: Audio: opus, 48000 Hz, stereo, fltp (dependent) Layer 3: 10 channels (FL+FR+SL+SR+FC+LFE+TFL+TFR+TBL+TBR) Stream #0:0[0x0]: Audio: opus, 48000 Hz, stereo, fltp (default) Stream #0:1[0x1]: Audio: opus, 48000 Hz, stereo, fltp (dependent) Stream #0:2[0x2]: Audio: opus, 48000 Hz, mono, fltp (dependent) Stream #0:3[0x3]: Audio: opus, 48000 Hz, mono, fltp (dependent) Stream #0:4[0x4]: Audio: opus, 48000 Hz, stereo, fltp (dependent) Stream #0:5[0x5]: Audio: opus, 48000 Hz, stereo, fltp (dependent) Signed-off-by: James Almer <jamrial@gmail.com>
