Error while opening encoder for output stream #0.0 - maybe incorrect parameters such as bit_rate, rate, width or height about carrierwave-video HOT 5 CLOSED

Hello, are you able to get ffmpeg to do the transcoding you want via the command line?

I'm trying to determine if this is an issue with this particular gem or with your ffmpeg install.

from carrierwave-video.

I am able create a video using the command line using this option
--qscale 0.1 -ar 44100 -ab 128k -y

But when tried to create a video with the gem , I get unknown encoder 'libfaac' error

from carrierwave-video.

We've set the default audio codec for mp4 to the libfaac codec which you don't have installed.
https://github.com/rheaton/carrierwave-video/blob/master/lib/carrierwave/video/ffmpeg_options.rb#L82

You can pass in your own audio codec in the options (or re-install ffmpeg with libfaac).
Here are supported codecs: https://trac.ffmpeg.org/wiki/AACEncodingGuide

e.g.

process encode_video: [:mp4, resolution: "200x200", audio_codec: 'aac']

from carrierwave-video.

Thanks for the reply.

I really tried to reinstall the ffmpeg. I followed the guide .
https://trac.ffmpeg.org/wiki/UbuntuCompilationGuide

Now I tried this option::

process encode_video: [:mp4, resolution: "200x200", audio_codec: 'aac' ,custom:"-strict experimental -ar 44100 -ab 128k -y -qscale 0.1"]

It worked but I got another error.

Overlay area (0,0)<->(605,58) not within the main area (0,0)<->(200,86) or zero-sized
Error opening filters!

Errors: encoded file is invalid.

So How can I solve this problem?

from carrierwave-video.

Have you tried using the :same option to the resolution? It might be an issue with trying to make a 200x200 video from one which is (it looks like) 605x58.

Have you gotten this to work on the command line or by using the streamio-ffmpeg gem directly? If you can't get it to work via command line, you should turn to the ffmpeg community. They will be better able to answer your questions.

-- I'm going to close this issue for now because I don't think it's a problem specific to this gem.
