Thread: Philips PFL7605 TV and FastForward

  1. #1

    Default Philips PFL7605 TV and FastForward

    I've been trying out Mezzmo for my new Philips PFL7605 TV and although it can play everything I thow at it when using the Philips 8000 series profile, it also seems to think it has to transcode it all.
    So I've made some changes to the profile and managed to get it to only transcode the files the TV also can't play when using the built in USB.
    Now I have the odd problem that I cant use fast forward on any of the files that the TV plays on it own. It works fine when I play the files that get transcoded, but when I play the ones that don't the speed simply stays the same. When I play the same files via USB fast forward works fine.
    Is there some setting I can use in the profile that will fix that?

    Can you please post your update profile here or send to support (at) conceiva (dot) com, so that we could include it in the next release of Mezzmo as well? It would be great for other Philips owners to have. Thanks!

    Regarding FF/REW - it should allow you to do that for non-transcoded files of course. Maybe there's something in the profile that I'll spot.

    It seems all I actually ended up adding to the profile was support for WMV3.
    I also changed the user agent so it would autodetect the TV correctly and the contentlength because it would only play the first 30sec or so of each file otherwise.

    I've been trying to tweak the profile a bit, but unfortuantely when I get something to work I break something else

    I have a number of WMV files in a few different formats. WMV3/WMAV2, WMV3/WMAPro and WMV2/WMAV2.
    The only ones the TV will play on its own are WMV3/WMAV2, the rest are all transcoded to MPEG2/AC3 with the current profile, because the TV doesn't seem to support WMAPRO or WMV2.

    Since the TV does support WMV3, I don't seen any reason to trancode the WMV3/WMAPro ones to MPEG2 though, that seems like a waste of CPU and disc space. So I've managed to just make it transcode the sound to WMAV2. However that has resulted in the WMV2 files no longer being transcoded, so I can't play those any more

    The only thing I changed in the previously posted profile was setting encode=1 for the wmv3/wmav2 lines I added.

    How do I get it to transcode the WMV2 files to a playable format again, while still only transcoding the sound of the WMV3/WMAPro ones?

    As for the FFwd issues, it seems that it is only a problem with WMV/AVI files, MPEG2 works just fine. It would be a shame to have to transcode all the files I have just so I can use FFwd though...

    Can you please post (or send to support) FFmpeg information on the files that play and those that don't (and should be transcoded) and based on that I should be able to make a working device profile.

    The problem is that FFmpeg doesn't currently (at least our current build of FFmpeg) transcode to WMV3 (Windows Media Video 9), it transcodes to WMV2 and WMV1 though. If the TV doesn't support WMV2, then looks like we'll have to transcode it to MPEG2... Maybe the TV supports WMV2 in combination with WMAV1, for example?

    According to the documentation the TV supports the following:

    Picture Playback Formats: JPEG
    Music Playback Formats: MP3, WMA (v2 up to v9.2), AAC
    Video Playback Formats: Codec support:, H264/MPEG-4 AVC, MPEG-1, MPEG-2, MPEG-4, WMV9/VC1, Containers: AVI, MKV

    Just to make sure I tested if it would support WMAV1, but it doesn't.

    I did somehow manage to get it to only transcode the sound of the WMV3 files now though, while still transcoding the WMV2 files to MPEG2.

    Code:
    <avcontainer id="asf" name="asf" encode="1" mimetype="video/x-ms-wmv" format="asf" supportschunked="0">
            <video>
                    <format id="wmv3" encode="1" codec="wmv3">
                    </format>
            </video>
            <audio>
                    <format id="wmav2" encode="0" codec="wmav2">
                    </format>
            </audio>
            <audio>
                    <format id="other" encode="1" codec="wmav2">
                    </format>
            </audio>
    </avcontainer>
    It's probably not the proper way to do it but it works

    The "id" portion in the device profile is the codec as reported by FFmpeg, so "other" would not be used (it'll be ignored). So, the above is the same as saying:

    Code:
    <avcontainer id="asf" name="asf" encode="1" mimetype="video/x-ms-wmv" format="asf" supportschunked="0">
            <video>
                    <format id="wmv3" encode="1" codec="wmv3">
                    </format>
            </video>
            <audio>
                    <format id="wmav2" encode="1" codec="wmav2">
                    </format>
            </audio>
    </avcontainer>
    Maybe transcoding to AVC would be a bit faster than to MPEG2 - we can try that, if you wish.
