IOS play ondemand video up to 1h:11min:52s

Report · Oct 31, 2012

We have a weird issue when we open some big videos on IOS.

The video are longer but the IOS open it up to 1h:11m:52sec

Opening the video using http on reagular player everything works ok.

Is there some default value to change in manifest or server to let the player open the file to a longer duration?

Can you provide more details about the file? Do you see any errors in error logs of Apache - if yes can you let us know what are the errors? Do other streaming protocols work fine with this file namely RTMP and HDS.

Do you have access to mediastreamvalidator tool - if yes can you run the same?

Using the other protocols everything works fine.

The problem is presento only using IOS opening the m3u8 manifest:

#EXTM3U

#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=64000

/stiletv-vod/ConvergenzeInnovationCenter.aac.m3u8

#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=300000

/stiletv-vod/ConvergenzeInnovationCenter_300.f4v.m3u8

#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=700000

/stiletv-vod/ConvergenzeInnovationCenter_700.f4v.m3u8

when i open the manifest i get only an error:

[Fri Nov 02 18:04:24 2012] [error] [client 195.60.190.156] File does not exist: /opt/adobe/fms/webroot/stiletv-vod

where stiletv-vod is the www root of the service:

<Location /stiletv-vod>
    HLSHttpStreamingEnabled true
    HLSMediaFileDuration 8000
    HttpStreamingContentPath "../webroot/stiletvvod"
    HLSFmsDirPath ".."
    HLSJITConfAllowed true

# Uncomment the following directives to enable encryption

#    HLSEncryptKeyURI        "https://<ServerName>/hls-key/vodkey.bin"

playing with HLSMediaFileDuration i am able to get a little longer duration, using 160000 i am able to read 1h13m.00s duration

we upgraded from 4.5.1 to 4.5.4 and now we have a full duration of the hls-vod streaming.

The problem is not fixed at all because after 1h.11min we have only audio and not video.

I am lost about it.

Your help is appreciated

Downloadind your files - its taking quite a time. Hopefully everything will be downloaded overnight - i'll check tomorrow once download is finised and get back to you.,

the problem seems related to the handling by FMS of the large f4v files. Encoding the file using mp4 everythin glooks ok.

So i will wait your test on f4v because it is crucial to our ore business to work on f4v.

Can i know how are you encoding the files? I ran mediastreamvalidator on this stream and it gives backward timestamps error - so it might be expected that it stops while streaming at that point. Also when i play the file - after 1h.11min.34s (for me it stops here) - the rest of the file is audio only - there is no video content.

FYI - i have still filed bug at our end to see what we find and maybe we can log something to indicate some error when we encounter any such thing - will keep you updated.

We use media encoder 4 (4.0.0.374) without changing any default value at 300 and 700kbps rate.

Do you have any advice about it?

Little confused - if you use same source and use the same encoder to encoder in "mp4" you see no issue but if you encoder it as "f4v" you see issue - is it so? I would assume then there is some issue with encoder. How was the source recorded at first place - which live encoder did you use and what were the settings? Was it live event published to AMS or was it Standalone recording of live event and then converted as you say using Media Encoder 4?

Report · Nov 07, 2012

you are right.

We publish and record a live event by Adobe Live Medi Encoder. The recording format is mpeg.

The Using cs4 in post production we create the f4v and/or mp4, the mp4 doesn't have issue; the f4v has the issue.

Some parameters:

Codec:MainConcept H.264 Video

dimensioni 720*396

frequenza fotogrammi : come da sorgente

codifica bitrate : CBR

Bitrate 0.7 Mbps

Audio Codec AAC freq. 44.1 Mhz

Hope thi scan help to find the issue, that now seems related to CS4 and not FMS.

So if i get you right, you saying you take "live" feed from Flash Media Live Encoder (I am assuming its FMLE as i have not heard about product called Adobe Live Medi Encoder) and then publish it to FMS and record it on FMS using some server-side code of your own and while recording you choose "mp4" as format - did i get you right? If yes - can you try below stuff

I am not sure what is the reason for post production stuff but probably before you use it post production - may be you can post process it using f4vpp and then pass it to CS4 and see if it helps resolving the issue.

yes you get it, sorry about misstypes.
