Can we have the ability to delete videos from AirServer interface on the remote server?

I temporarily store some video files on ramdisk. The path is /Volumes/RamDisk

In older versions (for example 2.1.0 beta 3) I can browse the folder and the files can be loaded.

In this new version, when I try to browse the folder, I keep getting this error message "Shared folder not found".

Any ideas?

Quick question: where can I download the 64bit verison of 2.1.0? I noticed that you released the 32bit version (albeit without an official announcement... why is that by the way? - just wondering).

 

Thanks!

This link should work

 

https://s3.amazonaws...D-2.1.0-x64.exe

 

although I'd recommend 2.1.1-beta1 instead.

Unfortunately it does.

Thanks! I'll give the new beta a try : - )

Thanks a lot for 2.1.1-beta1. Just came back and did some testing today.

 

VC-1 in M2TS works flawlessly now, very nice!

 

I found a problematic HEVC/H.265 file that for some reason won't get parsed correctly (Air Video HD gets stuck on "Loading details..." and times out with a "File analysis took too long" after some time, so no thumbnail and inability to play it back).

 

Here it is:

There are also some other videos (that are very demanding on the host CPU though, but they seem to have the same problem like the file above):

http://www.elecard.c...oad/videos.html

 

About the reference frames, can we expect support for that in beta2?

You mean passthrough with 16 ref frames? we can't affect that on server, it's handled on client.

This is most likely related to change in how we handle stale bookmark data. It seems that OS X handles the bookmark data for your ramdisk as stale. How exactly did you create it? I'll see if i can reproduce it.

Yes, exactly, passthrough (for Download and Direct Playback).

So with next client update?

Possibly. Regarding the HEVC files. Our current MPEG TS demuxer doesn't recognize the HEVC stream so I've fixed this.

 

However VLC 2.2 can't seem to be able to decode the stream properly. Also if we feed it to VLC Decoder it doesn't decode all frames. I'm not sure why, it could be also our parser. I'll look into that when I have some more time.

 

EDIT: It was our parser. The files should work in next server update.

VLC 2.2 wouldn't play for me at all... but ffplay played some frames. Seems like ffmpeg is better at decoding than VLC. I can only watch these HEVC videos if I use Daum PotPlayer. PotPlayer may have some hardware support that VLC and AirServer do not have. AirServer HD can't play the HEVC video unless I convert them first to MP4. :(

The decoder is the same, difference is in demuxer and parser. Next Air Video Server HD version will play the elgato test videos (using decoder from VLC 2.2).

This is a "late to the party" question but I just noticed the "Enable Hardware Accelerated Decoding/Encoding" options.

 

What are the benefits of those two settings? '

I gave it a try and noticed that conversion was around 20% slower when hardware acceleration was enabled.

Did you check CPU load? On fast computers the transcoding speed may be slower, but CPU load should be much lower.

Yes you are right. Just checked and CPU load is a lot less. Thanks for the clarification!

I've just found out that in the most recent AppleTV update 7.1 they have re-introduced MBAFF support (and maybe even PAFF). On iOS 8.2 there still is no support (you have to force deinterlacing on the iPhone for them to work). Not sure what Apple's plans are to be honest and why this sudden inconsistency. Maybe it's because of the soon to be announced TV streaming service, where content providers will need more flexibility again, so they re-introduced it.

 

Also, I've found another file that Air Video HD server doesn't play correctly (there are green frames appearing and the file doesn't play with the correct speed, like it skips some frames), VLC 2.2 and LAV filters play it perfectly fine.

 

I've uploaded it for you on your mediafire, it's called "Amiga Longplay [023] Apidya.mp4".

Sunrise, we don't really support H.264 in AVI. Putting H.264 in AVI is a bad idea. The presentation timestamps are missing in such case and our pipeline doesn't currently restore PTS for H.264 (since in *all* other containers the timestamps are present). I'd suggest to remux the file to MKV using mkvtoolnix, after which the file should play.
