ffmpeg converts .flv video to .gif with awful quality [migrated]
22 février 2013, par Kamil HismatullinI'm converting .flv movie to .gif file with ffmpeg.
ffmpeg -i input.flv -ss 00:00:00.000 -pix_fmt rgb24 -r 10 -s 320x240 -t 00:00:10.000 output.gif
It works great, but output gif file has a very law quality.
Any ideas how can I improve quality of converted gif ?
Output of command :
$ ffmpeg -i input.flv -ss 00:00:00.000 -pix_fmt rgb24 -r 10 -s 320x240 -t 00:00:10.000 output.gif

Overlaying jpg onto Mp4 using -VF
16 février 2013, par bruxI am using the following command to overlay a jpg :
ffmpeg -i in.mp4 -vf "movie=bb.png [movie] ; [in] [movie] overlay=0:0 [out]" -vcodec libx264 -acodec copy out.mp4
This works as expected with the first file (listed below) but it doesnt work with the second file. There is no error when I try with the second file, rather is creates an unusually large file that would not open :

At least one output file must be specifiedIn case it is important I am capturing these videos with Android devices. The first mp4 file is created by a Nexus 7, the second (the file which wont overlay the image) is created using a HTC Desire.

ffmpeg audio conversion distorted - half rate
6 novembre 2013, par user1688971I'm trying to convert an asf audio to mp3 using ffmpeg.
But I have one specific audio that gets distorted in the middle and starts like if the person was talking in slow motion (at half rate).The command I'm using is :
ffmpeg - i input.asf -ac 2 output.mp3
I've tried a lot of options, but about the middle of the audio is when it fails.
The raw file sounds good, so it's not the recording. It is af in the middle of the transmission the frame rate went down for some reason.Thanks all !
[EDIT]
I'm adding the console response after running the command as a suggestion from LordNeckbeard :
[root@mynasserver home]# ffmpeg -i recording-8532-1.asf -ac 2 -ab 64k -ar 44100 recording-8532-ac2-ar44100.mp3
