Still no mp4/aac encoding in kdenlive
Thanks for all the great work, David.
Still no mp4 rendering option in kdenlive. Haven't tried command line, yet.
Is this a regression or is the same issue on mga7? Please file a new bug upstream kdenlive. CC:

geiger.david68210 Thanks for the screenshot, it often helps a lot to understand a bug. Is your complaint that the output file is so huge? Does it playback? Or that kdenlive seems to offer MP4 output, but complains it is unsupported? You do have tainted enabled? > I've compiled my own version of ffmpeg to enable non-free codecs This is treading on thin ice; you are raising a bug with some DIY software. How does this differ from simply using the Tainted version? Have a look at Bug 26861 and see whether that helps. $ urpmq --requires-recursive kdenlive | grep x26 lib64x264_157 lib64x265_188 Is it worth trying to export the kdenlive project to something lossless that works, and play with ffmpg directly to convert it to [lossless]mp4 ? ffmpeg is extremely powerful & versatile, but not easy to drive. (We had a bug where it had been used to make a screencast!). CC:

I was able to render to mp4 using a non-free ffmpeg when we were at version 4.2.x. Could be that something has changed in 4.3 that is incompatible with kdenlive somehow. Will file a report upstream.

(We had a bug > where it had been used to make a screencast!). The issue is that kdenlive doesn't offer the option to render to mp4. Even with all the updates David did today. Yes, I do have tainted enabled. Yes, I do compile packages locally to enable CPU optimizations to inch out every ounce of performance I can from my old hardware. Upstream report: https://bugs.kde.org/show_bug.cgi?id=423950 (In reply to David GEIGER from comment #9) > *** Bug 26913 has been marked as a duplicate of this bug. *** Confirmed. Same situation here. Thanks Found the culprit. mlt needs to be either updated or recompiled. I updated it locally to git master and am now able to render to mp4. Assigning to Zezinho as the maintainer of mlt. Source RPM:

In fact, I think mlt just needs a rebuild, without git snapshot. I've tried but I get QT5 errors that I'm sure you'll know how to fix much better than me : http://pkgsubmit.mageia.org/uploads/failure/cauldron/core/release/20200708203058.zezinho.duvel.7589/log/mlt-6.20.0-3.mga8/build.0.20200708203102.log What'a Team, What'a Team!!!!! mlt fixed and rebuilded! Looks good today. I've been able to render an MP4 file after updating. Thanks to all. Closed! Resolution:
