Google's standard for FLV (as used on older versions of YouTube player and Google Video player) involves at least 2 additional metadata tags. These are starttime and totalduration. The value for starttime should be 0, and totalduration should be equal to the official Adobe Flash Video standard "duration" metadata tag. But there's a problem. These tags are of type DOUBLE, not STRING, and FFMPEG only allows the insertion of STRING type metadata tags, at least from what I've seen.
If this isn't already possible in FFMPEG, please consider this a feature request for future versions. FFMPEG developers, please hear my reasoning for this feature. This is important for making the FLV files work correctly in Google's old video players. I have a copy of one of those players (the actual SWF file, as downloaded from an archived copy of a video.google.com webpage on the Internet Archive Wayback Machine, archive.org). I've successfully embedded the player in a website I have hosted on my own PC via the Mongoose web server software. And I've managed to successfully make it play 2 FLV files. One is directly from the old Google Videos website (again archived on the Wayback Machine), and the other I got from converting (via FFMPEG) one of my own video files to the FLV format. The original Google FLV file works completely without glitches in the webpage embedded Google Video player. The one I got from converting another video file to FLV does play but it has issues. These issues are that it says NaN for both the start and stop times in the player's time display, and also that I can't seek at all in the video. I can only let the video play through all the way from beginning to end. If I could add the DOUBLE-type metadata tags starttime and totalduration, I would likely have a working FLV file, which would play perfectly in the Google Video player. _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
