I tried running 0.25-fixes mythtranscode in place of my 0.26-fixes<br>
mythtranscode but ran into library dependancy hell,<br>
I'm just thinking our loud here but given the state of mythtranscode<br>
should the dev's just up-port 0.25 mythtranscode or is there<br>
some other<br>
reason these bugs are not being addressed? or are others not<br>
experiencing these issues?<br>
<br>
the alternative lossless cut options are not nearly as reliable,<br>

due to issues with HDHR recordings also rather I/O intensive<br>
works much<br>
better with ionice -c3<br>

Works great with simple cuts only ie. leading/trailing only, not<br>
so good<br>
with Ad removal<br>
<br>
<br>
As the perpetrator of this script, let me comment. It works well<br>
for me for recordings (DVB-T UK) where the video is identified by<br>
ffmpeg as 'mpeg2video (Main)', which it cuts using Project-X. For<br>
other formats short audio glitches are to be expected at internal cuts.<br>

Hi John,<br>
<br>
And thank you for your script.<br>
<br>
yes video is identified the same ie.<br>
[NULL @ 0x72f180] start time is not set in estimate_timings_from_pts<br>

I'm is Australia and what I'm finding is simple cuts work great but<br>
anything beyond a few cuts causes parts to be cut out incorrectly and<br>
creates files ALOT smaller then expected.<br>

Hmm. Sorry to hear that. All my mpeg2 stuff is 720x576 or less and it works ok. There's a note on the wiki page about the remuxing failing at higher bitrates, and an mkv workaround, but I've not used that myself.<br>
<br>
Cheers,<br>

John<div class="HOEnZb"><div class="h5"><br></div></div></blockquote><div>OK sorry I dont know how I missed that thread or the comment on the wiki, <br><br>is this ment to go into the existing script?<br><br>mythffmpeg -fflags +genpts -i $DEMUXPREF.m2v -i $DEMUXAUDIO -vcodec copy -acodec copy "$OUTFILE"<br>
<br>or is this a manual work around, It is more than likely a HD issue as the one that work reliably are not HD, perhaps this can be used only on a specific channel or perhaps depending on the resolution, what are your thoughts on automating this?<br>
