Ah ok, I was just wondering because the packet count changes from 4 to 65 while the packet size stays at 24000. Didn't notice that a two-step process (encoding with limited frame-count into file, then separate decoding to get the framemd5) is performed here in contrast to other tests with frame-count limit.On Thu, 14 Mar 2024, Tobias Rapp wrote:On 08/03/2024 01:53, Marton Balint wrote:This makes the wav and pcm demuxer demux bigger packets, which is more efficient.[...]+0, 136000, 136000, 2000, 24000, f952be1e1c7d48acd73d652ef4ea3aad +0, 138000, 138000, 2000, 24000, e42cbabef9d9675429dcb6fa28ce39f4 +0, 140000, 140000, 2000, 24000, 9c6613b980bcbe9ebacbb6a492f53b16 +0, 142000, 142000, 2000, 24000, 1882d1ae4b08fa7cc848eba60d645463 +0, 144000, 144000, 2000, 24000, a361b56ba31c90557689631f0e7afc63 +0, 146000, 146000, 2000, 24000, 341fbe24112c4060bb643750895a9041 +0, 148000, 148000, 2000, 24000, 38340ef2ef764bb8007efe9cd0af54d7 +0, 150000, 150000, 2000, 24000, 9b013a00bbedad211ba33326a3cfaa6e +0, 152000, 152000, 2000, 24000, 9d3469da4442cdfd2b8a5beacb789701 +0, 154000, 154000, 2000, 24000, cf8e3880ecb46011328135dba1015044 +0, 156000, 156000, 2000, 24000, 3be9fa7d0e0541269339ee032bda4021 +0, 158000, 158000, 2000, 24000, ffd2646acf86524651416bc412afd846 +0, 160000, 160000, 2000, 24000, 715163d8f82f007b1b6c42b06bd08b5a +0, 162000, 162000, 1840, 22080, c2079a237d021d7aa27e44acf979b1f0Noob question: Isn't a much larger total number of samples produced here?The command line which generates the daud file specifies -frames:a 20, and 20 from bigger packets will cause a longer output file.
Also it might be good to mention in the commit that the audio duration is less exact when using commands like "ffmpeg -i $INPUT -c:a copy -t 1.0 $OUTPUT".Ok, will add this to the commit message.
