I am working on android application that crop videos using ffmpg,This works fine for all videos but not for videos recorded by phone camera,I have noticed that all these kind of videos has "rotate" parameter greater than 0 in video stream meta data. Here is ffmpg complete command
ffmpeg -y -i /storage/VID_20.3gp -vf crop=280:70:176:0 -c:a copy -threads 5 -strict experimental -preset veryslow /storage/VID_203.3gp
This is output of above command
Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height
and this link to output of ffmpeg report
If I try to specify the codecs using following command
ffmpeg -y -i /storage/VID_20.3gp -codec:v x264 -vf crop=280:70:176:0 -c:a copy -threads 5 -strict experimental -preset veryslow /storage/VID_203.3gp
Then error changes to following
[NULL @ 0x4115d960] Unable to find a suitable output format for 'crop=280:70:176:0' I: crop=280:70:176:0: Invalid argument
and this link to output of ffmpeg report
