Hi To add information to my last post, when I open it in MTS4ea (Tektronix measurement tool) I’ve got this message and can’t open the file : No sequence_header_code found within 5242880 bytes of start position Stream position: 0x0 (dec.0), bit 0 Bitstream context: []
I understand that there is a problem ;-) but that’s all So, I need help to do a h264 video in a avi file and I would like to use the quantification control (CRF) Hope someone help me De : [email protected] [mailto:[email protected]] De la part de Christophe Nelson Envoyé : vendredi 24 mai 2013 14:56 À : This list is about using libavcodec, libavformat, libavutil, libavdevice and libavfilter. Objet : [Libav-user] X264 issue : Black Frame Hello I’ve got a problem to play files encoded with x264. I ‘ve done this : ffmpeg.exe -i InputFile -c:v libx264 -preset slow -crf 20 -c:a copy OutputFile.avi When I read this file in VLC, GraphEdit, there’s no problem But when I read it in VirtualDub, MSU quality measurement, avitoyuv.exe I have 5 black frames at the beginning ! I’m pretty sure I use FFDshow in all this software (exepted in VLC). Could someone help me ? Do I need to install codecs ? Do I need to changed my ffmpeg command line ? Regards
