Re: Re : : Only sound but no video (black screen)

Hello Sébastien,
Yes, indeed bad news… but we'll get there!
Anyway, I am testing and setting up the streams directly in VLC player (see snapshot in annex), so I am not working with command lines.
What I discovered is if I stream the file with a transcoding profile with “Encapsulation”=MPEG-TS to another file, the stream works fine for Video and Audio. While if I use a transcoding profile with “Encapsulation”= FLV (or also MP4/MOV) the stream does not work anymore (no Video).
What concerns the Transcode command you are using mux=flv, shouldn’t this be mux=ffmpeg{mux=flv} ?
Anyway, could you send me the transcoding lines that you are using in Enigma TV so that I can do some trials with it and eventually make some slight modifications to make it work for me and let you know?
Thanks,

Best regards.

Hello Sébastien,
Thank you for sending me these files and sorry for the late reaction.
1) Unfortunately I don’t have good news because the problem is still not solved with start time = 2 sec:
a) The record (that I have send to you) now works fine with the new settings BUT there are other records that worked fine before and that now do not work anymore (no video) with the new settings (start time = 2 sec).
b) Also the problem with sometimes “no video” after channel switch is still present!
=> Start time = 2 sec does not seem to be the right solution and I would therefor suggest NOT to implement it as a standard modification for future EnigmaTV releases.
2) However, I have been doing some further tests with VLC streaming and I found a solution that seems to work fine on all my records: When I select for the transcoding a streaming profile with “Encapsulation” = MPEG-TS (instead of the MP4/MOV that is standard suggested by VLC), all the streams seem to work fine.(see snapshot in annex).
a) What is the “Encapsulation” format that is standard used in Enigma TV?
b) Could you try to change it to MPEG-TS and test my record?
c) Can you then send me by email a zip file with the adjusted enigma files so that I can test the EnigmaTV streaming on all the records and on channel switch?

Thanks again for your help and sorry for insisting.
Best regards.

Hello Sébastien,
Thanks for your fast reaction.
I already tried to set this option directly in the "preferences" of the VLC that is used by EnigmaTV but unfortunately this does NOT help.
=> Any chance that you can send me by email a zip file with the EnigmaTV files including the corrected source code?

Thanks and best regards.

Hello Sébastien,

This is good news. This will probably also solve my "no video" problem after channel switch (but still to test). Strange that you have to set it at 2 sec because for me (stream directly in VLC) it also works on 1 sec with sound and video.
All my sympathies that you want to spend more time with your family during Chritmass holliday!
However, is there a possibility that I can already implement and test this new setting (MyMedia.AddOption("start-time=2") with Enigma TV? In this way I can also test if the occasional 'no video" at channel switch is also solved so that we can hopefully state that your tool is also compatible with the VTI 6.05 image (running on my VU+duo). Also my daughter will be happy to be finally able to watch TV and records in her "student room" without any problems.
Thanks again and further enjoy hour Christmass Holidays.
Best regards.

Please don't give up yet, because I am convinced that togheter we can find a solution and I think we are close:
Facts are:
1) If you "play" the file directly in the mediaplayer of Enigma Server or directly in VLC player all works fine with Video!
2) If you try to "stream" the file using Enigma TV or even using VLC directly the stream starts without Video!
3) IMPORTANT: If I change the "start time" to 1 sec in the VLC preference settings (Tools/ Preferences) -> see snapshot in annex. Then close VLC completely and then open VLC again, load the file and start the stream => Then it works with Video.
=> The only thing is that using the Enigma web browser it still does not work (because the 1 sec start time is not implemented?)
Could you please try to repeat your tests with the start time = 1 sec and if possible implement this in EnigmaTV!
Sorry for insisting and thanks again for your time.
Best regards and enjoy the Christmas holidays![/quote]

Hello Sébastien,
In the meantime I have send you a download link to the record (+/-700MB) with "WeTransfer" to your email address.
=> Can you add it to your "Medias" and try to stream it via Enigma webbrowser?
=> Please keep me informed about the outcome; I would realy like to have this problem solved!
Thanks again for your time.
Best regards.

Hello Sébastien,

I could understand a relation between box image and the problem of streaming some channels but what has the box image to do with not being able to stream a record stored on the harddisk of the box or even on the local harddisk of the PC on which Enigma is installed?
Why don't you want to try streaming one of these record on your site with Enigma webbrowser just to check if you see the same problem and evetually to perform a debug?

Best regards.

Hello Sébastien,
I am not able to solve this problem. What I tried in the meantime is:
1) Changing settings in VLC player (in the EnigmaTV directory) in Tools/ Preferences, the "Input & Codecs" settings => no succes!
2) Installing Enigma TV server on another PC => Same problem!
So, I am becoming desperate now!
As mentiond my problems are:
a) By streaming (local or public) with webbrowser, after channel switch, sometimes no video on some channels. This problem never occurs on FTA channels; I have also never problems by streaming these channels with the Webinterface.
b) Same problem with the streaming of some records (in Medias). While playing these records in Enigma Server or direcly in VLC everything works fine.
=> I know you are very busy but can you please try to help me solving this problem. Again, if you want I can send you (via dropbox?) a record that is giving this problem so that you can analyse it.
Thanks and best regards.

Hello Sébastien,
Is it useful if I try to change in de VLC player (in the EnigmaTV directory) in Tools/ Preferences, the "Input & Codecs" settings to try to solve my problem or is the Enigma tool not working with the settings in "Preferences" ?
Best regards,
