#1570: libv4l2: error dequeuing buf: Resource temporarily unavailable -------------------------------------+------------------------------------- Reporter: llarevo | Owner: Type: defect | Status: open Priority: important | Component: avdevice Version: git-master | Resolution: Keywords: v4l2 | Blocked By: regression | Reproduced by developer: 1 Blocking: | Analyzed by developer: 1 | -------------------------------------+-------------------------------------
Comment (by llarevo): All requested testcases were broken with the current git, except the ffplay commands without -r 25. In other words: ffmpeg doesn't work neither with or without -r 25, while ffplay does work only without -r 25. In Detail: == 1. compiled without --enable-libv4l2 == '''1.1 ffmpeg -loglevel debug -f v4l2 -s vga -r 25 -i /dev/video0 out-vga- 2M-5min.mpg: BROKEN''' {{{ ffmpeg version N-49795-g478fc7f Copyright (c) 2000-2013 the FFmpeg developers built on Feb 10 2013 19:25:16 with gcc 4.7.2 (GCC) 20121109 (Red Hat 4.7.2-8) configuration: --prefix=/usr/local libavutil 52. 17.101 / 52. 17.101 libavcodec 54. 91.102 / 54. 91.102 libavformat 54. 62.100 / 54. 62.100 libavdevice 54. 3.103 / 54. 3.103 libavfilter 3. 37.101 / 3. 37.101 libswscale 2. 2.100 / 2. 2.100 libswresample 0. 17.102 / 0. 17.102 Splitting the commandline.
