ffmpeg not working after repository change

[samrat_rao]

Hi,

I am using both 64 bit and 32 bit versions on different desktops.

After i was told by Trevor to replace rpmforge repo by rpmfusion repo viewtopic.php?f=14&t=47690, i changed all the dependencies and packages from rpmforge to rpmfusion. But now ffmpeg is now working correctly when i want to reduce resolution from 1080p to 720p.

This command used to give good quality videos when ffmpeg was from rpmforge:

Code: Select all

ffmpeg -i input.mp4 -y -b 5120k -s hd720 output.mp4

But now the above command gives an error:

I searched on the net and tried some options, the one that works for ffmpeg from rpmfusion is:

Code: Select all

ffmpeg -i input.mp4 -y -acodec copy -s hd720 output.mp4

But this process takes a lot of time as the number of frames per second is very less. Also output.mp4 has jittery video quality. There is nothing wrong with input.mp4 as the old ffmeg worked correctly on input.mp4, the new ffmpeg does not.

Thanks for any suggestions.

If you don't get any answer here, I'd suggest you ask on the ffmpeg mailing list.

Hi Toracat, thanks for the reply.

Actually i downloaded ffmpeg-2.6.2 and compiled it: ./configure --prefix=/usr/local/pkgs/ffmpeg_2.6. This ffmpeg works fine with this command

Code: Select all

ffmpeg -i input.mp4 -y -acodec copy -s hd720 output.mp4

Do you still suggest that i write to the ffmpeg mailing list?

[scottro]

I don't keep track of which distribution's version does aac and which don't

However, if you use

Code: Select all

ffmpeg -i input.mp4 -y -b 5120k -s hd720 -acode aac -strict -2 output.mp4

I suspect it would work. It was probably copying the codec, which was probably aac, which in most versions of ffmpeg that I've used in RH based distributions, meaning rpmforge's, nux's, (I think) and rpmfusion, aac is considered experimental--depending upon the actual command you give--for example had you run it with -acodec copy, you might have gotten the message which is something like aac is experimental, to use it add -strict -2 or something like that--sorry, don't remember the exact message or what I did to get it.

But no, I wouldn't write the ffmpeg mailing list. Apparently the vanilla version works.
