I thought I could do WEBM as it's essentially a MKV with specific video, audio & subtitle codecs, but as far as I've been able to tell, there is no player that accepts the WEBM subtitle codec... :'( looking at your console output.. > > keyint=250 > > maybe try and have those more often? > > or maybe try and pad the beginning with a few black frames? > I have tried adding keyframes to the beginning, but I haven't tried this, adding it to the list of things to try... > if it works 99% of the time does that mean videos seem to faile 1% of the > time at random? or can you try again and it will work properly? > It doesn't matter how many times I re-encode a file, the same file will always fail. I've tried making *just* a video from the image sequence and that works, but once I add the audio & subtitles it breaks. I've even tried letting it choose my codecs by removing the `-codec copy` part of my command line (the h264 video needs to stay because my I know my Pi will play that). Same result. I'm almost to the point of hitting up the ffmpeg developers list and filing this as a bug... I'm seriously at a loss as to what to do. It's just so weird that taking the same clip and encoding only 10 seconds of it works, but encoding 20 seconds breaks... :-/ And whole episodes break also... Maybe, is there a way to extract all of the streams in a file to a bunch of separate files without reencoding them, and then assemble them back together? Basically to get rid of the original file completely? _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
