[SOLVED] FFmpeg transcode video for Galaxy Blaze Samsung

lindylex · 03-11-2013, 02:40 AM

I'm trying to convert a video for my Galaxy Blaze Samsung using the following command.

Code:

ffmpeg -i o.mp4 -vcodec libx264 -crf 20 -threads 4 -flags +loop+mv4 -deblockalpha 0 -deblockbeta 0 -cmp 256 -partitions +parti4x4+parti8x8+partp4x4+partp8x8+partb8x8 -subq 7 -refs 5 -bf 0 -flags2 +mixed_refs-fastpskip -coder 0 -me_method full -me_range 16 -g 250 -keyint_min 25 -sc_threshold 40 -i_qfactor 0.71 -qmin 10 -qmax 51 -qdiff 4 -vsync 2 -acodec libfaac -ac 2 -ab 160k -vol 1280 -async 1 -f mp4 -vf "scale=800:428,pad=800:480:0:26:white" sample.mp4

It use to work and now it complains with the following error.

“Unknown encoder 'libfaac'
”

Info about o.mp4

Does anyone suggest a better ffmpeg command to transcode my video for the Galaxy Blaze Samsung?

Thanks

Try using 'libvo_aacenc' instead of 'libfaac'. Or it could be that you don't have libfaac installed or your ffmpeg is too old.

[ SOLUTION SOLVED ]

Code:

ffmpeg -i o.mp4 -vcodec libx264 -crf 20 -threads 4 -flags +loop+mv4 -deblockalpha 0 -deblockbeta 0 -cmp 256 -partitions +parti4x4+parti8x8+partp4x4+partp8x8+partb8x8 -subq 7 -refs 5 -bf 0 -flags2 +mixed_refs-fastpskip -coder 0 -me_method full -me_range 16 -g 250 -keyint_min 25 -sc_threshold 40 -i_qfactor 0.71 -qmin 10 -qmax 51 -qdiff 4 -vsync 2 -acodec aac -strict experimental -ac 2 -ab 160k -vol 1280 -async 1 -f mp4 -vf "scale=800:428,pad=800:480:0:26:white" sample.mp4

This is the command I used. Do you suggest a better command to create a video for this phone? This currently works and I would like to see if there is anything better.

Use ffmpeg -codecs to get a list of all the codec names available. Also pay attention to the configuration flags list at the top of the output screen. This will show you what libraries your version of ffmpeg has been compiled to support.

BTW, why do you think you need to re-encode anyway*? For most android phones these days you can find players that will support almost any media configuration imaginable. If the default player doesn't work with a given file, how about trying a different one? I've found BSPlayer to be very good, and there's a version of VLC available too.

(*Unless of course you just want a smaller file size for better storage and less stress on the phone during playback, or something like that. But the one you posted doesn't seem particularly burdensome.)

This is why.

This is my final ffmeg string for creating videos for the Galaxy Blaze Samsung. This part is not needed " scale=800:428,pad=800:480:0:26:white". It is there because the original video was larger than the phones display resolution which is 800X480.

Code:

ffmpeg -i o.mp4 -vcodec libx264 -crf 20 -preset medium -acodec aac -strict experimental -ab 160k -ar 44100 -ac 2 -vf "scale=800:428,pad=800:480:0:26:white" sample.mp4

Thanks for the input.
