HP TouchPad

Hello,

I just recently got my hands on an HP TouchPad(TP) after the price dropped significantly. I got the Bhome app and tried to stream from my desktop to my TP. It didn't work using WMP12 media sharing so I went looking for solutions. I found Serviio while I was looking for mediatomb alternatives in WIndows. This is a great little UPnP server.

I added a HP TouchPad profile to the profiles.xml file and then realized that Serviio doesn't transcode .xxx INTO MPEG4 which is the only video format supported by the TP. I was wondering if this could be added somehow?

With the recent flood of TPs entering the wild, it would be great if Serviio could get ahead of the pack.

Here is the profile I created below. I would LOVE to change the targetVCodec attribute to "mpeg4video" if possible.

  Code:

<Profile id="14" name="HP TouchPad" extendsProfileId="1">
      <Transcoding>         
         <Video targetContainer="mpegts" targetVCodec="mpeg2video" targetACodec="aac">
            <Matches container="asf" />
            <Matches container="avi" />
            <Matches container="mp4" />
            <Matches container="matroska" />
            <Matches container="flv" />
            <Matches container="wtv" />
         </Video>
         <Audio targetContainer="mp3"> 
            <Matches container="mp4" />
            <Matches container="asf" />
            <Matches container="lpcm" />
            <Matches container="flac" />
            <Matches container="ogg" />
         </Audio>
      </Transcoding>   
   </Profile>

MP4 is not stream friendly so it nto a case of just adding it. So until FFmpeg find a way to sport it serviio wont have it.

out of intrest what OS is the HP running??

[zip]

does it support mp4 container or mpeg4 video codec (divx, avc)

out of intrest what OS is the HP running??

The TouchPad runs WebOS 3.0+.

does it support mp4 container or mpeg4 video codec (divx, avc)

I am not sure, I think mpeg4 video. These are the formats supported by WebOS. http://h18004.www1.hp.com/products/quickspecs/14077_na/14077_na.pdf

Audio: DRM-free MP3, AAC, AAC+, eAAC+, AMR, QCELP, WAV
Video: MPEG-4, H.263, H.264
Images: JPEG, PNG, BMP, GIF

[zip]

so those are video codecs. Not sure what containers it plays. can you find at least some videos you can play without transcoding?

[Cerberus]

from a quick read on the net ( hehe im suposwed to be working ) it seem that you are in teh same boat as apple devices and only an MP4 container is supported by teh device and sadly this will not currently work with FFmpeg ( system serviio uses to transcode files ).

that makes me sad.

On my old iPad, there was an app called Air VIdeo which let you stream from your PC to an iOS device as long as you installed their Air VIdeo Server on your PC. I wonder how they do it.

thanks guys anyway for your help. i'll continue to use serviio for audio, at least.

EDIT: I was looking around and they used a custom build of FFmpeg linked with libX264. hmmm...

still wont work as has to be in a MP4 container

I have some native mp4 files that stream wonderfully through serviio to my HP Touchpad. However 99% of my videos are divx avi or wmv files and I can't stream them to my Touchpad without transcoding.

There is another program that does transcode and stream unsupported videos containers to the touchpad, but the program lacks configuration control and limits the bit rate so badly the videos look like crap. That is why I decided to try serviio.

Well - this one is odd for me.

Running serviio and mythtv both doing their jobs, I can view 'Finding_Nemo.mp4' from my Tocuhpad running 'BHome-UPnP' from the mythtvs inbuilt server fine. Servio (on the defaul generic profile) isnt doing it, so it has to be possible. anyway - mediainfo on the file is thus (I used Handbrake to squish it) and I never expected it to run on the touchpad at all - target was actually android! Not sure what myth is doing to it, there is no re-encoding, so I'm optimistic you can get this to work.

Nb. Serviio is the kind of code I would love to be able to write - excellent stuff. One 'want' would be the ability to add 'ffmpeg' options as an extra to let me tweak stuff to get widescreen out of my Panny BDT210 blu ray.

Ok - an update on this. And quite strange. It appears servio will send all my 'mp4' files happily to be played on the touchpad ONLY when I browse to them via Folder view in the client. the file above was done using handbrake, but most were done using vlc on the commandline. Thus, another that works:

yes that correct mp4 in native format ( not trancoded ) will work fine but that not what the OP was asking , as that would mean all your files had to be in mp4 format as we CAN NOT transcode to mp4 container as its not supported by ffmpeg.

for andorid download skifta and rockplayer lite ( both free ) from market place and ALL files will work with the generic profile.

[Coastie]

I was also here hoping Serviio could transcode to my HP Touchpad.

coastie please read my above post, as it explain the issue and give a fix.

[Coastie]

I'm confused, the solution is to install andriod apps 'skifta and rockplayer' and install in WebOS to fix?

no read my first sentance if your running webOS

but if your touchpad is running android then you can use the adroid apps i mentioned

From my experience with mediatomb, the touchpad can play mov containers as well as mp4 containers which use the h264 codec, though it is a bit more particular with the sound codec used. It will also play mov or mp4 files created by ffmpeg if qt-fastart is used on the resulting file. That is, if the codec used in your video is h264, a change of container and possibly sound transcoding is all that is needed. This is a fast operation since there is no need to transcode the video. I use this method with mediatomb and UPnP AV player to play my videos although the 3.04 update causes problems. It would be great if the same method would work with serviio. If serviio can perform a multi-command transcode similar to the following it should work:

  Code:

PATH1="/media/tempStorage"
ffmpeg -i "$1" -vcodec copy -acodec pcm_s16le -ac 2 -y -f mov "$PATH1"/TVID.mov && (qt-faststart "$PATH1"/TVID.mov "$PATH1"/MP4VID.mov & (sleep 1;cat "$PATH1"/MP4VID.mov > "$2"))
