Ffmpeg Check Codec

If you don't know whether a codec has the capabilities you need (e.g. in a s

cript), it's possible to check for both the codec function (s) and codec name in a similar manner: ffmpeg -v quiet -codecs | grep '.*DE.*opus' ^ name of codec you would enter on command line ^^ D=Decoder; E=Encoder

to check your video specification when mediaifno confusing or you are curiou

s to know another altrenative tool much stronger . FFmpeg is the leading multimedia framework, able to decode, encode, transcode, mux, demux, stream, filter and play pretty much anything that humans and machines have created.

Many libx264 encoder options are mapped to FFmpeg global codec options, whil

e unique encoder options are provided through private options. Additionally the x264opts and x264-params private options allows one to pass a list of key=value tuples as accepted by the libx264 x264_param_parse function.

First ffmpeg searches for a file named codec_name-arg.avpreset in the above-

mentioned directories, where codec_name is the name of the codec to which the preset file options will be applied. For example, if you select the video codec with -vcodec libvpx and use -pre 1080p , then it will search for the file libvpx-1080p.avpreset .

FFmpeg list all codecs, encoders, decoders and formats A codec is the logic

to encoding or decoding a media stream, there are many different types with popular ones being H.264, HEVC (H.265) and MPEG-4.

strict experimental -b:a 192k -shortest output.mp4 15. Trim a media file using start and stop times. To trim down a video to smaller clip using start and stop times, we can use the following command. $ ffmpeg -i input.mp4 -ss 00:00:50 -codec copy -t 50 output.mp4. Here,

The following command reads file input.mp4 and transcodes it to output.mp4 w

Here you will see that my own copy has capabilities for 10 bit encoding. An

installation of FFmpeg compiled against this version of x265 can produce a decent 10bit encode with the following command: ffmpeg -i input.mp4 \ -c:v libx265 -preset medium -crf 28 -pix_fmt yuv420p10le \ -c:a aac -b:a 128k \ output_10bit.mp4

Most of our FFmpeg codec here are running pretty slow. More work might need

to be done to improve the speed. FFmpeg actually provides the option like setting up the desired bit rate to speed up the encoding, but this would cause some downgrade to the video quality.
