############################ FFmpeg Documentation Tips ############################-metadata[:metadata_specifier] key=value (output,per-metadata)
For example, for setting the title in the output file:
ffmpeg -i in.avi -metadata title="my title" out.flv
To set the language of the first audio stream:avisrunyard@gmail.com
ffmpeg -i INPUT -metadata:s:a:0 language=eng OUTPUT
-disposition[:stream_specifier] value (output,per-stream)
For example, to make the second audio stream the default stream:
ffmpeg -i in.mkv -c copy -disposition:a:1 default out.mkv
To make the second subtitle stream the default stream and remove the default disposition from the first subtitle stream:
ffmpeg -i in.mkv -c copy -default_mode infer_no_subs -disposition:s:0 0 -disposition:s:1 default out.mkv
"-preset" provides the compression to encoding speed ratio. Use the slowest preset you can.
"-bufsize" sets the buffer size, and can be 1-2 seconds for most gaming screencasts, and up to 5 seconds for more static content.
If you use "-maxrate" 960k then use a "-bufsize" of 960k-1920k. You will have to experiment to see what looks best for your content.
"-g" Use a 2 second GOP (Group of Pictures), so simply multiply your output frame rate * 2.
For example, if your input is -framerate 30, then use -g 60
"-crf 0", short for “constant rate factor,” is used to tell the libx264 encoder to use “lossless mode.”

#################### Methods of Reducing file size with FFmpeg ####################
# https://trac.ffmpeg.org/wiki/EncodingForStreamingSites
##### Modify the bitrate, using:
ffmpeg -i $infile -b $bitrate $newoutfile
##### Vary the Constant Rate Factor, using:
ffmpeg -i $infile -vcodec libx264 -crf 23 $outfile
##### Change/scale the video screen-size (for example to 1080p or half its pixel size):
ffmpeg -i $infile -vf "scale=iw/2:ih/2" $outfile
# This method takes care of error: (libx264) "height not divisible by 2"
# https://stackoverflow.com/questions/20847674/ffmpeg-libx264-height-not-divisible-by-2
# https://superuser.com/questions/624563/how-to-resize-a-video-to-make-it-smaller-with-ffmpeg

-movflags faststart -profile:v high -pix_fmt yuv420p -metadata:s:a:0 language=eng \

-metadata:s:a:0 language=eng -c:v libx264 -c:a copy "output.mp4"
##### Change the H.264 profile to "baseline", using:
ffmpeg -i $infile -profile:v baseline $outfile
Use the default ffmpeg processing, using:
ffmpeg -i $infile $outfile
##### Bitrate Guidelines:
# Calculate the bitrate you need by dividing your target size (in bits) by the video length (in seconds). For example for a target size of 1 GB (one giga<em>byte</em>, which is 8 giga<em>bits</em>) and 10,000 seconds of video (2 h 46 min 40 s), use a bitrate of 800 000 bit/s (800 kbit/s):
ffmpeg -i input.mp4 -b 800k output.mp4
##### example 1:
# ffmpeg -i input.mkv -c:v libx264 -preset medium -b:v 3000k -maxrate 3000k -bufsize 6000k \
# -vf "scale=1280:-1,format=yuv420p" -g 50 -c:a aac -b:a 128k -ac 2 -ar 44100 file.flv

##### Concatenation https://trac.ffmpeg.org/wiki/Concatenate
for f in ./*.mkv; do echo "file '$f'" >> mylist.txt; done
##### Note that these can be either relative or absolute paths. Then you can stream copy or re-encode your files:
ffmpeg -f concat -safe 0 -i "mylist.txt" "output.mkv"
##### Concatenate multiple media files
for f in ./*.mkv; do echo "file '$f'" >> mylist.txt; done
ffmpeg -f concat -safe 0 -i "mylist.txt" -b 4292k -c copy "Top.Gear.Patagonia.Special.1080p.mkv"
##### Map only English audio stream and English subtitle streams if it exists

-default_mode
This option controls how the FlagDefault of the output tracks will be set. It influences which tracks players should play by default. The default mode is ‘infer’.
'infer'
In this mode, for each type of track (audio, video or subtitle), if there is a track with disposition default of this type, then the first such track (i.e. the one with the lowest index) will be marked as default; if no such track exists, the first track of this type will be marked as default instead (if existing). This ensures that the default flag is set in a sensible way even if the input originated from containers that lack the concept of default tracks.
'infer_no_subs'
This mode is the same as infer except that if no subtitle track with disposition default exists, no subtitle track will be marked as default.
'passthrough'
In this mode the FlagDefault is set if and only if the AV_DISPOSITION_DEFAULT flag is set in the disposition of the corresponding stream.
