Where/how to get up-to-date ffmpeg onto ubuntu 16.04 desktop ?

[mc4man]

Well till something better comes along maybe try mp4 > mkv, seems to work here ok. Before was trying a mpeg from hubble telescope so it didn't have audio. That went ok as far as avi > mkv. Just tried this sample with both a/v & the avi to mkv failed as you've seen.

wget http://samples.mplayerhq.hu/MPEG1/zelda%20first%20commercial.mpeg

ex. here,.mpeg to .mp4 to .mkv

As far as 'not new', I've seen mailing list stuff about this error with mpeg-ts going back a couple of years or so.

As far as 'not new', I've seen mailing list stuff about this error with mpeg-ts going back a couple of years or so.

As I mentioned, the specific files that I personally am working with are actually MPEG-PS, not MPEG-TS. (But that's a small detail.)

Anyway, I do agree that the evidence suggests that this specific ffmpeg bug is not particularly new. It's still a bug however. Too bad none of the ffmpeg folks think its worth fixing. (Several other programs, e.g. handbrake, kodi, vlc, smplayer, have no problems at all coping with the relevant input files. It's only ffmpeg that is balking when asked to copy the contained streams to a .mkv file. I have trouble understanding why ffmpeg can't either find or manufacture timestamps, as necessary, in order to make the MKV container format happy. Obviously, somewhere within the input files there must be some kinds of clues about when things are supposed to appear. Otherwise, how would all of the players I mentioned... and also handbrake... know how to play these same files properly... which they do.)

Have you heard of FFmbc? A long time fork of FFmpeg with many fixes mainly aimed at broadcast situations and used by some of the biggest broadcasters around the world. It may well have the fixes you require.

https://github.com/bcoudurier/FFmbc

I've not used in a few years and seems the old Google Code site is empty so can only assume that above is the correct migration. Seems the latest version forked from the official FFmpeg not long again and patched. It definitely used to have a lot better transport stream handling and professional formats available for both input and output. (We used it on Linux boxes used for ingesting of news media for a company I used to work for where xmf and imx formats were required and not supported by FFmpeg.)

Is there a way to install ffmpeg with all the dependencies listed without utilizing the PPA? I tried to install ffmpeg using the current .deb file on the ffmpeg web site however it stated that the listed dependencies are necessary for installation. Is there a way to install the dependencies because using GDebi does not install the dependencies like it normally does for other .deb installations. Lubuntu 16.04 (that PPA I think is the one which messed up my installation-be careful-apparently it uninstalls some very important files associated with Lubuntu and there is no other fix other than a complete reinstall).
