FFMPEG converting problems with flvs

Gixm87 posted 2008 Jul 24 16:35

Hello I am using linux hosting with FFMPEG service and I have a script to upload and convert video files. All files work just fine except .flvs I am having a problem with them where after it takes a snapshot(which is there) it converts but then the video is lost for some reason. I am using ffmpeg -i '.$newnameoldvideo.' -t 00:05:00 -y -f flv '.$newnamenewvideo.' I dont understand why the video isnt there afterwards Any help is greatly appreciated.

hello sorry i didnt get back sooner to post a reply I fixed the problem with flvs but now I am having a completely different problem non related to flvs where a WMV that has already been compressed ALOT (1.37 megs before upload) gets distorted and torn apart during the conversion process and I cant figure out why. Is it just going to tear already very low quality videos? O and now I also ran into a problem where when I try to limit the length of the video it only ends up with the first 5 seconds or so not the 5 minutes

first of all try updating the ffmpeg build the wmv decoding has several problems, now "should" be resolved, or at last try (btw you can upload the wmv somewhere for testing) BHH

as for the build I really wish I could I am going to open up a support ticket with my hosting company. ive been trying a few things and I find that when I convert to .avi then upload it works just fine but I dont know if other people will be able to get that done. I am actually not sure what version ffmpeg I am using since it is shared hosting but I am going to try to have them update it. Thanks for the help.

ffmpeg -version should get the info you need BHH

I tried that what i did was exec('ffmpeg -version > ffmpegversion.txt'); I am only able to use php the server does not allow SSH connection but it doesnt output the information into that text file I dont understand why. you got any ideas?
