Greetings and Salutations! Have two audio tracks in SRT feed, sometimes more, sometimes less, sometimes 2.0, 4.0 or 5.1 channels.
Is there any method to ID audio tracks in astat report? `ffmpeg -i "srt://foo/bar" -map 0:a -af "astats=metadata=1:reset=1:measure_perchannel=RMS_peak:measure_overall=RMS_peak,ametadata=print" -f null /dev/null` Already am doing FFprobe, then `-filter_complex "[0:a:0]...[0:a:X]..."` and it works, but is cumbersome, as each SRT session init takes 4-5 sec. Trying to use just an `-af astat..`, but fail to link astat report to audio track ID/PID. https://pastes.io/ffmpeg-711-astats lines:3117-3128 ` [Parsed_astats_2 @ 0x60000131c240] Channel: 1 [Parsed_astats_2 @ 0x60000131c240] RMS peak dB: -39.055850 [Parsed_astats_2 @ 0x60000131c240] Channel: 2 [Parsed_astats_2 @ 0x60000131c240] RMS peak dB: -38.042769 [Parsed_astats_2 @ 0x60000131c240] Overall [Parsed_astats_2 @ 0x60000131c240] RMS peak dB: -38.042769 [Parsed_astats_2 @ 0x600001318180] Channel: 1 [Parsed_astats_2 @ 0x600001318180] RMS peak dB: -28.492663 [Parsed_astats_2 @ 0x600001318180] Channel: 2 [Parsed_astats_2 @ 0x600001318180] RMS peak dB: -31.100664 [Parsed_astats_2 @ 0x600001318180] Overall [Parsed_astats_2 @ 0x600001318180] RMS peak dB: -28.492663 ` Basically can I link 0x600001318180 to a channel ID 0x60000131c240?
