    Je ne sais pas trop non plus. Peut-être que le commit mentionné sur https://docs.droidian.org/porting-guide/debugging-tips/ joue un rôle.

    Je suis bloqué un peu après maintenant. Les outils v4l avec /dev/video* ne semblent pas marcher. J'ai regardé le code source de droidian-camera, qui utilise GStreamer. J'ai essayé ça:

    gst-launch-1.0 droidcamsrc mode=2 camera-device=1 ! jpegdec ! jpegenc snapshot=TRUE ! filesink location=test.jpeg

    Sans succès:

    library "libstagefright_ccodec.so" not found

Setting pipeline to PLAYING ...
