Re: Video in Pharo

by Jupiter Jones

Another step forward. I created a new ubuntu 22 install, installed pharo 11 and installed spec-gtk. The first issue was the libraries are named: libgobject-2.0.so.0 and libpango-1.0.so.0 with the â.0â suffix. I created links to those with the names spec-gtk is expecting. Then, the little test window opened but looked like this: ï¿¼ Is there something else Iâm missing? Thanks for your advice.

Re: Video in Pharo

by Russ Whaley

I can't help you with GTK as I'm one of the unfortunate Mac users. However, I've used the Pharo-LibVLC extensively - although not for video, so my experience may or may not be relevant for you. One of the capabilities for Pharo that is sorely under-documented is FFI. Yes, there is an FFI document, and no, it was not helpful to me when using VLC. Admittedly, I am notoriously dim-witted, however I was unable to grasp how to set up a call-back for/from VLC. Some of this has to do with the poor VLC documentation... i.e. trying to find a method/memVar that lets you know when a song has ended! There are a couple of 'got'chas' in the VLC package that locked me up dozens of times before I wrote work-arounds - but the biggest issues I've encountered is not knowing what VLC is doing... ie: - is it still playing? -I'd like to start the next song in MY playlist - so I can show which song is playing - I can't find a method in VLC that tells me this - where is it in the song (progress/time)? I'd like to show a progress bar for the song that is playing. - I'd like to know if another service in Pharo is currently using the library - as multiple calls also locks it up. - statuses are inconsistent - (playing, stopped, mute, etc.) - depending on when you ask. If you ask whether VLC is muted - when a song is not playing, it might say yes or no (usually no). But then the song plays and you get no sound... yup, it was muted. Overall, Pharo-LibVLC is a great leg up in using VLC, but I had to put that project on hold as I couldn't solve the issues above. Let me know if you start working with Pharo-LibVLC in earnest - I'd love to share experiences and see if we can help each other.

Re: Video in Pharo

by Jupiter Jones

Hi Esteban, Thanks for your reply. Iâm running on macOS so I think youâve helped me identify the issue :) The target is macOS and PiOS so Iâll give it a go on the pi. For now I can work on Linux until the Mac issue is resolved. The process is to zeroconf pharo 11, then install spec-gtk based on the instructions on GitHub: Metacello new repository: 'github://pharo-spec/Spec-Gtk'; baseline: 'SpecGtk'; onConflict: [ :e | e useIncoming ]; onUpgrade: [ :e | e useIncoming ]; ignoreImage; load â¦then save and quit. Relaunching fails. Iâll keep an eye out for the macOS fix. Thanks again for your help.

Re: Video in Pharo

Hi, Spec-Gtk should work without problems on P11, except on macs, where there is a known problem. what is the process you are taking to install it? where are you trying it? I don't know the status of the VLC bindings.

Re: Video in Pharo

The stark silence answers my question :) Soâ¦ I found a nice binding to VLC [1] and was thinking of using Spec2 GTK+ to create a video widget/component. Does anyone with more in depth knowledge of Spec2 and GTK foresee any obvious blocks? First block :) I canât find a way to play with the Spec2 GTK+ binding [2] without the image crashing on startup. I see someone has already logged the issue in GitHub for 10 and 11, and I tried 12 just for fun, and it also ate all the memory then crashed. Is there a Pharo version that will work with the Spec2 GTK+ binding installed? Maybe Iâm looking at this too early :) [1] https://github.com/badetitou/Pharo-LibVLC [2] https://github.com/pharo-spec/Spec-Gtk > On 3 Jul 2023, at 5:07 pm, Jupiter Jones <jupiter.jones(a)mail.com> wrote: > > Can anyone point to to some library, documentation or examples of how to play video in Pharo? > > Thanks in advance. > > Cheers, > > J

Hi Offray, that is very interesting material, and well described. No, it doesn't have to be OrgMode per se, I just wanted to make use of something that already can support a GTD workflow and implement something on top of it gradually. I look deeper into this - thanks a lot! cheers, Siemen
