That was also posted by me - same model Hikvision NVR except back then I was retrieving MPEG-TS stream using inner Hikvision API. > As a work-around, you can record the stream with something else than ogg (for > example avi) and then re-encode that file, the result should contain sane > timestamps. > If you use the option "-rtsp_transport tcp" you should not see the errors > that are in your console output, "-qscale 2" ensures maximum quality, you can > reduce the bitrate when encoding to ogg. Tried it and while it does normalize the video duration and makes audio constantly heard, the audio does not match the video's time - I can see people talking on the video but there is only silent noise (same noise when the room is empty) output from the audio. Here is a sample converted to .avi container and then encoded to Thora: https://www.dropbox.com/s/971plokoty9nc9r/out.ogg?dl=0 George A. _______________________________________________ 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".
