I have not made any changes to the script since early May 2018 and have made few new HD recordings. Added options for output as Recording, Video, or Test reading input as 1 or 2 streams, and NC to ignore cutlist.Īdded an updated version of mythTScut_20180622.sh I hope that it will be possible to find ffmpeg options to address these issues. Processed recordings usually play without trouble in mythfrontend or via UPnP but the positioning of switchpoints is still slightly imprecise and there may be a/v sync transients after them. Both options usually work after a first pass with option 1 and no cutlist. I feel that 2 is likely to be better eventually, but at present it fails on raw recordings with 'interactive tv' streams not recognised by mythffmpeg. At present it has options to read single video and audio streams either 'together' or 'independently' (1 or 2). It uses tools from mythffmpeg and does not use mkv tools or Project-X. I have added an experimental script, mythTScut20180309.sh, originally intended for cutting h264-encoded recordings but potentially useful for other. It can be called here immediately after, and in the same way as, the existing 'mythutil -clearcutlist' section below. v0.2 introduced 'mythutil -clearbookmarks' that will allow restoration of the expected behaviour. Mythfrontend playback of programmes recorded with pre-roll and cut with MythDVBcut would then start at a point some time after the start-of-new-file. Johnp ( talk) 12:33, 28 July 2015 (UTC)īuilds of MythTV Master after mid-April 2015 (v0.2) may insert a 'mythical' bookmark at the scheduled programme start. I have also removed the version from March 2013. Editing for local conditions will be required, as before. This is a direct paste of the script as I use it with v0.2-g7f68683 under SL7. Current version attached as mythDVBcut_20150728.sh I'm still using essentially the same process here, but with some changes for 0.28-pre. Thanks to Michael Stucky for his suggestions. The choice is made by editing the MAKEMKV Boolean variable in the script.

I'm posting a new version that can create either 'DVD format' or matroska files after cutting by ProjectX. In the 'grep' lines for stream count and video stream selection replace 'mpeg2video' or 'Video' by 'mpeg2video (Main)'. I'm still using mental arithmetic to convert, but users not in the UK may find this more inconvenient.Īn unannounced change at my local transmitter makes mythffmpeg find multiple 'Video' streams in some DVB-T channels this causes an error exit. MythTV 0.26 filenames are based on UTC, while the Mythfrontend display uses local time. Two 'features' have become apparent since the script was first posted: I move the resulting file to my Video storage group, the file is playable on my MythFEs and all my other media players.' Where $OUTFILE is the recording name with an. Mythffmpeg -fflags +genpts -i $DEMUXPREF.m2v -i $DEMUXAUDIO -vcodec copy -acodec copy '$OUTFILE' The only way I have been able to get consistent results is to use mythffmpeg to remux into an mkv container.

'Further tests indicate that a trial-and-error process is/maybe required for each HD recording (channel?) to get a clean run of mplex. He gave a workaround and comments that I reproduce here for convenience: Soon after this was posted, Michael Stucky reported that the call to mplex failed when the script was used on an HD recording from an HDHR device. This may well depend on the editing processes at source. I find that edits at the last/first keyframes that show a wanted picture usually give acceptable results. The link between the editor-based cutlist and the cutpoints actually used differs slightly from both the earlier versions. The user interface is largely unchanged I use it from the keyboard. It might well be useful for other formats, at least for removing pre-and-post run. It provides more info about what it has done and, although restricted to cutting at keyframes, usually cuts where I would like it to. This updated script works for me with 0.25-fixes and 0.26-fixes for both dvb-t and dvb-t2. This script is based on one I've been using for several years to process my recordings from dvb-t, and another, less often, for recordings from dvb-t2.
