I'm using Cumulus Clips to upload some videos from work to other work people.
When I use the following thumbnail command with a WMV file, all is good.
/usr/bin/ffmpeg -i /home/USERNAME/public_html/URL/video/cc-content/uploads/flv/IIcPkfU9qu7MuuMrb5uY.flv -ss 427 -s 480x360 -r 1 -t 1 -vframes 1 -vcodec mjpeg -f mjpeg /home/USERNAME/public_html/URL/video/cc-content/uploads/thumbs/IIcPkfU9qu7MuuMrb5uY.jpg
And the resulting stream mapping is:
Stream mapping: Stream #0.0 -> #0.0 Press [q] to stop, [?] for help frame= 1 fps= 0 q=5.5 Lsize= 23kB time=00:00:01.00 bitrate= 187.9kbits/s video:23kB audio:0kB global headers:0kB muxing overhead 0.000000%
However, when I try an AVI (which is the most important file format to work), the stream mapping is:
Stream mapping: Stream #0.0 -> #0.0 Press [q] to stop, [?] for help frame= 0 fps= 0 q=0.0 Lsize= 0kB time=00:00:00.00 bitrate= 0.0kbits/s video:0kB audio:0kB global headers:0kB muxing overhead -nan%
In the resulting logs, all values are identical for both file types until the very last line with thumbnail stream mapping.
I have tried to solve this for 3 days, unsuccessfully and cannot find an option that will work for AVI files.
How do I get ffmpeg to generate useful thumbnails from AVI files?
