The installer should replace ##FFMPEGPATH## with - well the path to ffmpeg Usually c:\program files\ipimp\utilities\ffmpeg\ffmpeg.exe

Similarly the installer should replace ##LISTEN## with the IP: Port that the iPiMP app is listening on. e.g. 127.0.0.1:80.

Thanks for the info. I will do that.

If I remember correctly you're the iPiMP user that does an 'existing Apache install' - I guess in all the excitment I didn't put these changes in for that type of install. I'll fix that for the next version.

Excellent memory, you are absolutely right about me being "an existing Apache install" user I will make the changes in config.xml as you mentioned.

I did the changes in config.xml and I got as far as till the Play/Stop button page. But clicking on Play button gives the following error:

The requested URL /SmoothStream/live.m3u8 was not found on this server.

I can see the card tuning in tv.log

Can you post your config.xml

 

[Khurram]

Can you post your config.xml

Sorry, I should have posted it first:

<appconfig>
<transcoders>
<transcoder name="SmoothStream" usetranscoding="1" filename="&quot;G:/Program Files/iPiMP/Utilities/ffmpeg/ffmpeg.exe&quot;" args="-i - -threads 0 -re -vcodec libx264 -fpre &quot;G:/Program Files/iPiMP/Utilities/ffmpeg/ffpresets/libx264-iPiMP.ffpreset&quot; -b 256k -s 420x272 -acodec libfaac -ac 2 -ab 64k -ar 48000 -ac 2 -async 2 http://<pc name>:<port>/SmoothStream/live.ism?stream_id=live-256-64k.ismv" inputmethod="2" outputmethod="4" />
</transcoders>
</appconfig>

I am using my pc's netbios name for <pc name> and the port iPimp is listening on for <port>.

 

[RickDeckard]

I get the same error "The requested URL /SmoothStream/live.m3u8 was not found on this server." as reported above.

my config.xml:

<appconfig>
  <transcoders>
    <transcoder name="SmoothStream" usetranscoding="1" filename="&quot;C:\Program Files (x86)\iPiMP\Utilities\ffmpeg\ffmpeg.exe&quot;" args="-i - -threads 0 -re -vcodec libx264 -fpre &quot;C:\Program Files (x86)\iPiMP\Utilities\ffmpeg\ffpresets\libx264-iPiMP.ffpreset&quot; -b 256k -s 420x272 -acodec libfaac -ac 2 -ab 64k -ar 48000 -ac 2 -async 2 http://<URL>:80/SmoothStream/live.ism?stream_id=live-256-64k.ismv" inputmethod="2" outputmethod="4" />
  </transcoders>
</appconfig>

Using iPimp 5 for MP 1.0.2 on a previously installed Apache instance.

Some other findings that may help in pinning this down:

• timeshifting starts correctly - I can see the timeshifting taking place in the TV Server configuration tool
• after timeshifting starts ffmpeg appears briefly in Windows taskmanager for a few seconds, but then quits
• in the /SmoothStreaming folder, a file called Channel.txt is created
• I do not see any intermediate files being created in the folder I have designated for storing transcoded files, I assume this is expected behaviour? (Where does iPimp actually store the timeshifting and transcoding buffers?)

Sorry - iPiMP installs 2 versions of ffmpeg, the original used for manual or scheduled transcoding and a patched version for Smooth Streaming. You've selected the unpatched on, so edit your config.xml with this:

<transcoder name="SmoothStream" usetranscoding="1" filename="&quot;G:/Program Files/iPiMP/Utilities/ffmpeg_patch/ffmpeg.exe&quot;" args="-i - -threads 0 -re -vcodec libx264 -fpre &quot;G:/Program Files/iPiMP/Utilities/ffmpeg_patch/ffpresets/libx264-iPiMP.ffpreset&quot; -b 256k -s 420x272 -acodec libfaac -ac 2 -ab 64k -ar 48000 -ac 2 -async 2 http://<pc name>:<port>/SmoothStream/live.ism?stream_id=live-256-64k.ismv" inputmethod="2" outputmethod="4" />

I will be tidying this up so that only one version of ffmpeg is deployed in a future version.

See the post above about 2 versions of ffmpeg.

For info - the Smooth Streaming files will appear in the same folder as Channel.txt

AW: Live TV streaming

@cheezy
which bitrates are used for livestream? Want to check if my local upload speed is high enough.

 

[cheezey]

Re: AW: Live TV streaming

The default is 256k video and 64k audio. Those are defined in config.xml so can easily be edited.

AW: Live TV streaming

mhm that must be OK i've 923 kBit/s upload speed but it is only working fine with WLAN :-( with UMTS video player is rebuffering every 20 or 30s
