Where do you take that time offset value from? I'm also working on such kind of scripts right now, because I want to remux especially HD recordings to MKV. In the case of movies broadcasted by ARD HD or ZDF HD (720p@50Hz), they are full of so-called filler-NALUs, which can be removed just by muxing into MKV not directly by ffmpeg, but by mkvmerge, which shrinks a 10GB movie to about 3GB. My problem is still A/V sync, all the original TS chunks (I also record into 200MB pieces, because of fast editing in VDR) show video delays for each audio track of over 1 second, which is also very noticeable ion the final converted MKV. The delays are reported both by tsMuxeR and mediainfo see for example the "Video delay" value below: mediainfo 00001.ts General ID : 8008 Complete name : 00001.ts Format : MPEG-TS File size : 200 MiB Duration : 2mn 6s Overall bit rate : 13.3 Mbps Video ID : 6010 (0x177A) Menu ID : 132 (0x84) Format : AVC Format/Info : Advanced Video Codec Format profile : High@xxxx Format settings, CABAC : Yes Format settings, ReFrames : 5 frames Duration : 2mn 5s Bit rate : 11.5 Mbps Width : 1 280 pixels Height : 720 pixels Display aspect ratio : 16:9 Frame rate : 50.000 fps Resolution : 8 bits Colorimetry : 4:2:0 Scan type : Progressive Bits/(Pixel*Frame) : 0.249 Stream size : 172 MiB (86%) Color primaries : BT.709-5, BT.1361, IEC 61966-2-4, SMPTE RP177 Transfer characteristics : BT.709-5, BT.1361 Matrix coefficients : BT.709-5, BT.1361, IEC 61966-2-4 709, SMPTE RP177 Audio #1 ID : 6020 (0x1784) Menu ID : 132 (0x84) Format : MPEG Audio Format version : Version 1 Format profile : Layer 2 Duration : 2mn 5s Bit rate mode : Constant Bit rate : 256 Kbps Channel(s) : 2 channels Sampling rate : 48.0 KHz Video delay : -1s 340ms Stream size : 3.84 MiB (2%) Language : German Language, more info : Clean effects Audio #2 ID : 6021 (0x1785) Menu ID : 132 (0x84) Format : MPEG Audio Format version : Version 1 Format profile : Layer 2 Duration : 2mn 5s Bit rate mode : Constant Bit rate : 256 Kbps Channel(s) : 2 channels Sampling rate : 48.0 KHz Video delay : -1s 344ms Stream size : 3.84 MiB (2%) Language : German Language, more info : Clean effects Audio #3 ID : 6022 (0x1786) Menu ID : 132 (0x84) Format : AC-3 Format/Info : Audio Coding 3 Duration : 2mn 5s Bit rate mode : Constant Bit rate : 448 Kbps Channel(s) : 2 channels Channel positions : Front: L R Sampling rate : 48.0 KHz Video delay : -1s 486ms Stream size : 6.73 MiB (3%) Language : German Language, more info : Clean effects _______________________________________________ vdr mailing list vdr@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr
