TVHeadend not using codec copy on an IPTV stream ?
3 avril 2020, par petaireSo I'm using the great TVHeadend, which is in my case a DVB-T or IPTV server that can record greatly some inputs. This is a great piece of software, which I recommend much.



But I'm a little bit confused in here. So I've set up a tvheadend on a raspberry pi 4, because I need for my work to record a lot of tv programs. I appreciate TVheadend very much on an other installation, and so are my coworkers who also needs to use it and not a CLI only interface (that's relevant you'll see).



So when I'm using a simple ffmpeg command like this :



ffmpeg -err_detect ignore_err -i http://mystream -to 00:10:00 -codec copy /media/partage/dvr/test.mp4



my cpu usage goes to something like 1 or 2% percent. But when I'm trying to replicate that in tvheadend, the cpu goes to 400%, and clearly it's not the same behavior.



Here my stream configuration :






Here's the result with ffmpeg codec copy :

As you can see, Tvheadend is making a variable bitrate and variable framerate file, which is really bad for Premiere Pro (which is the main goal for all this). Clearly it's transcoding it, which I don't need, in a format that is worst for my workflow.



My Pi4 is on Raspbian Buster, but I've also tried this with the same unfortunate result on libreelec.



Does anyone has any idea ?

Is there any way to edit just the track data of an AVI file, like mkvpropedit does with MKV files ?
20 juillet 2016, par hmj6jmhI am trying to swap the order of 2 audio tracks of an AVI file using
ffmpeg.ffmpeg -i "infile.avi" -map 0:0 -map 0:2 -map 0:1 -c copy "outfile.avi"This works but the file is being re-encoded, not copied. It takes much longer than a straight copy to finish and the resulting file is larger than the original.
Is there any way to edit just the track data of an AVI file, like mkvpropedit does with MKV files ? Command line tool preferred.
