how to fix h264?

[hanugro]

hi all is there any apps that can fix video encoded in h264 like divfix or divfix++ do with avi? i got clip that show wrong time (show clip length 36hr where it is only 1.5hr clip). also it has prb with seek function. many thanks.

In what video container? mkv, mp4, avi?

You could try run it through for example avidemux, under video and audio choose copy and save as an mkv,mp4,avi.

more probably your sample is corrupted

better to reencode the original, or to download a correct file

thanks for prompt reply (as always). the file is .avi but vlc said the audio is vorbis which i suspect it should be mkv.

ffmpeg is able to mux ogg audio in avi

check with avinaptic

you can try remuxing on mkv...

well i am thinking to avoid redownload since i am on slower broadband.

i will try to demux with ffmpeg..

ffmpeg -i myfile.avi -an -vcodec copy stream.avi
ffmpeg -i myfile.avi -vn -acodec copy stream.ogg

divfix the stream.avi (attention.. you could lose syncronization...)

remux into mkv

ok will try both later. so it will change h264 to standard avi?

[buzzqw]

no it will copy video stream to avi container

post an avinaptic report of file

Hm, this is odd. I try ffmpeg and now the resulting avi file is fine (shows correct timing and noproblem with seek. However I found that the video and audio is not showing the same time. Video is around 1:12:09 while audio is 1:11:59 (around 10 second differences). What is the best way to combine audio and video again and try to sync it as close as possible, want to avoid mkv if I can.

Edit: I use mkvtool and it seems OK. I will live with it at the moment, thanks for helping me!
