transcoder: update echov5

[acelinkio]

marking as draft: Application starts, however I need to check a few things. my lab might be having issues.

IDE complained about what part of code i'm not familar with. unused write to field Keyframes.. i've tried with original code (and what is checked in right now)

	if ret.Versions.Keyframes < KeyframeVersion && ret.Versions.Keyframes != 0 {
		for _, video := range ret.Videos {
			video.Keyframes = nil
		}
		for _, audio := range ret.Audios {
			audio.Keyframes = nil
		}

attempted to resolve with AI help

if ret.Versions.Keyframes < KeyframeVersion && ret.Versions.Keyframes != 0 {
    for i := range ret.Videos {
        ret.Videos[i].Keyframes = nil
    }
    for i := range ret.Audios {
        ret.Audios[i].Keyframes = nil
    }

In both cases, an issue came up that appears to be related to my lab. transcoder shows logs that its processing. Ui shows the loading bar. Might be some slowness in my network/storage. Might be a known issue with the build. Will debug what is happening in the next couple days.

that sounds like an error
