(I don't know how to ensure this will thread properly with my previous message, but perhaps the subject line will suffice). I made some progress re: the strange pts... to recap, this capture command: ffmpeg -f alsa -ac 2 -i hw:CARD=Cx231xxAudio,DEV=0 -f v4l2 -i /dev/video2 -c:a copy -c:v rawvi

[FFmpeg-user] Nvidia Transcoding: Failing Using xstack (When Running Under systemd)

2024-11-18 Thread Shane Warren
I have been trying to track down why when transcoding using xstack with nvidia decoding and encoding I get strange decoding issues in ffmpeg. Note: I use 2 1 minute long .ts files for this example if you want my inputs, they are available here (as input1.ts and input2.ts) : https://drive.google

[FFmpeg-user] sidechain compression: NOT ducking, but envelope

2024-11-18 Thread Michael Werzowa via ffmpeg-user
Dear List, I am new to the list. Searched the last two years of the list for „sidechain“, and did not find a hint. My usecase: Using an audio file to provide an envelope, that is applied to another audio file, modulating the gain of this file. With ffmpeg I easily can manage „ducking“, via direc

Hi - I am capturing to an .avi file in linux, and the resulting file has stuttering audio. If I demux the streams (1 video and 1 stereo audio) they play fine on their own. If I simply remux the broken file like this:     ffmpeg -i test.avi -c:a copy -c:v copy test-remuxed.avi ...the "remuxed"

Thank you for the answer. The sidechain file is an audio file, so, to my understanding, cannot be unipolar – but maybe I misunderstand? Best regards, Michael -- *** Michael Werzowa A-1190 Wien, Siolygasse 20/3B/6 +43 664 302 4511, fa

There is no standalone envelope filter in FFmpeg, but there is one in Librempeg. (If envelope is standard definition by audio community) If you already have smooth envelope, you can use in FFmpeg sidechaincompress filter (takes two input streams) + amix filter. I could help more if I can look at
