That helps me with a few things that I was unaware of. That command is what I've typically used and have had good results with playing mp4's in various browser players and hence why I suggested the user try it. I know I'm not the end all be all of ffmpeg so I assumed others would have other suggestions. I'll update it and compare and see if I see different results. In regards to no audio present in the users question I confess I didn't think to look.
A question then is raised for: The actual solution is shown in the console output: "No pixel format specified, yuv444p for H.264 encoding chosen. > Use -pix_fmt yuv420p for compatibility with outdated media players." > Of course, another solution is to use a more capable player. Are you and ffmpeg suggesting that movflags faststart not be included in the command, and that simply changing to -px_fmt yuv420p will play mp4 files better? Without the movflags faststart present I've seen certain browsers balk at playing mp4s without it. _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user
