AppImages give a poor experience #1919

Closed DylanC closed 5 years ago

DylanC commented 5 years ago

Just something I've noticed which I want to keep track of is the packaging of OpenShot. From working with an AppImage to working with my own version built from Source I noticed a huge difference.

The AppImage version is very glitch prone with both the video and audio. On the other hand with the same project file the version built from source is silky smooth and seems like a much more capable/polished video editor.

I think it may be (again) down to the AppImage bundling old versions of libraries but that's only a very rough guess.

ferdnyc commented 5 years ago

How is your libopenshot built, when you run it from source? I suspect that's the crucial factor, and I agree that the AppImage builds being outdated probably hurts it quite a lot. The AppImages are still (as of 2.4.2) bunding libopenshot linked with libavcodec.so.54, which seems to indicate FFMpeg anywhere between 0.11.x and 1.2.6?1

FFMpeg 1.2.6 was released (you'll recognize a pattern here, from my past AppImage bugs) in March 2014. FFMpeg is currently on version 4.0.2 (libavcodec.so.58.18.100), which libopenshot does not even support being built against (without patching). But libopenshot does support FFMpeg up to and including 3.4, which is still far more advanced than the AppImages are still including, and it's the version the Windows builds are shipped with. Probably MacOS as well.

I have asked, then offered, then begged to have the AppImage dependencies updated, and then I got tired of it and stopped begging. Nothing can be done in-repo because those pieces aren't in the repo. AFAICT they maybe come in via a zip file (artifacts.zip) held on the Gitlab instance that's handling build services. (I THINK, this is all based on inference from what used to be in installer/build-server.py, but is now split between there and .gitlab-ci.yml. When it was all in build-server.py it pulled files from /usr/jonathan/apps/ to do the packaging, which had the same problem. Now that it's split up it's even less comprehensible, and the tool that actually generates the AppImages is still referenced as /home/ubuntu/apps/AppImageKit/AppRun in the current version of build-server.py, if that's still actually used. Honestly the whole thing is nonsense.)

Until building and packaging libopenshot-audio, libopenshot, and OpenShot, in the same manner as the official builds — in fact, using the process that DOES generate the official builds — is moved in-tree and uses only the resources present in the repo (and configured dependencies, though ideally the repo source would be able to pull those in as well), then the packaging process is going to be magical, incomprehensible, and out of the control of anyone other than those with access to the build systems containing the necessary tools.

Notes

  1. (Possibly slightly higher than 1.2.6, hard to be more exact than that without the extended version #s — but definitely 1.2.x, as that series was followed by 2.0 which brought libavcodec.so.55.).

The single biggest highlight of that incredibly long list of changes is in 2.1: "HEVC decoder". 1.2.x didn't even have support for H.265 (aka HEVC) at all, which is something a lot of people care about.

But 2.0 also brought "10% faster aac encoding on x86 and MIPS", then "extensive native AAC encoder improvements" in 3.0; 2.7 had "DTS decoding through libdcadec", which 3.0 then updated with "new DCA decoder with full support for DTS-HD extensions"; ...Basically, the difference between 1.2.x and even 3.4, in terms of support for modern audio and video codecs, is immeasurable.
