No matter what I select, I get "SDL failed to open audio: No available audio device". I have two soundcards, ca0106 (Soundblaster Live) and internal HDA Intel (STAC92xx).

First, make sure the SDL_AUDIODRIVER is either unset or set to alsa: export SDL_AUDIODRIVER=alsa Then set AUDIODEV to pulse: export AUDIODEV pulse Then sound works! (Unfortunately, I cannot make my own post as a solution.)

Duration of video is about 1 or 2 minutes maximum. First, following this post "opencv for reading videos (and do the process),ffmpeg for audio , and SDL used to play both" sounds perfect. I have done some modification on the code considering recent ffmpeg naming changes. Compilation with cmake on 64-bits machine is fine.
