Input #0, image2, from '/mnt/nox2/development/example_exr/frames.%04d.exr':
  Duration: 00:00:04.17, start: 0.000000, bitrate: N/A
    Stream #0:0: Video: exr, rgb48le, 1920x1080 [SAR 1:1 DAR 16:9], 24 fps, 24 tbr, 24 tbn, 24 tbc
Codec AVOption vendor (vendor ID) specified for output file #0 (/mnt/nox2/development/ffmpeg_test_output_exr_h264.mov) has not been used for any stream. The most likely reason is either wrong type (e.g. a video option with no video streams) or that it is a private option of some encoder which was not actually used for any stream.
