I'm looking for some DNxHD ffmpeg help. I've stripped a more complicated command down to its barebones to try and get rid of this error. The error is:
Error while opening encoder for output stream #4:0 - maybe incorrect parameters such as bit_rate, rate, width or height As soon as I change 'dnxhd' to anything else, like 'dpx', it works. Is this an Avid codec issue? I'm pretty sure the included libavcodec has the lastest codecs in it. Is this an installation issue? An ffmpeg bug? User friggin' error? Here's the long-form output: jacobharris@devmac001 : ~/ffmpeg $ ./ffmpeg -i ~/sequence.*.dpx -vcodec dnxhd -f mov ~/movie.mov ffmpeg version git-2012-06-09-04e2ac4 Copyright (c) 2000-2012 the FFmpeg developers built on Jun 8 2012 19:09:52 with gcc 4.2.1 (Apple Inc. build 5646) configuration: --disable-yasm libavutil 51. 56.100 / 51. 56.100 libavcodec 54. 25.100 / 54. 25.100 libavformat 54. 6.101 / 54. 6.101 libavdevice 54. 0.100 / 54. 0.100 libavfilter 2. 78.101 / 2. 78.101 libswscale 2. 1.100 / 2. 1.100 libswresample 0. 15.100 / 0. 15.100 [image2 @ 0x10100f200] Stream #0: not enough frames to estimate rate; consider increasing probesize Input #0, image2, from '/home/jacobharris/sequence.1001.dpx': Duration: 00:00:00.04, start: 0.000000, bitrate: N/A Stream #0:0: Video: dpx, rgb48le, 2276x1138 [SAR 1200:1200 DAR 2:1], 25 tbr, 25 tbn, 25 tbc File '/home/jacobharris/movie.mov' already exists.
