Dear all,


Any idea why on some videos from veetle.com i am getting "GStreamer plugin H.264 decoder not available!"

Opening the video with VLC it uses the follwing Codec: H264 - MPEG-4 AVC (part 10) (avc1)

Opening the video with gst-lanch i am getting the following:

WARNING: from element /GstPlayBin2:playbin20/GstURIDecodeBin:uridecodebin0: No decoder available for type 'video/x-h264, stream-format=(string)avc, pixel-aspect-ratio=(fraction)1/1, width=(int)31417920, height=(int)17280000'.

Any idea what might be the issue? I thought H264 was supported hardware codec.

PS. I am using dm800se with the latest updates of OpenPLi.

I guess flv from gst-launch logs.

Yes, I've seen that before. I think it has something to do with the flv container in combination with gstreamer. Somehow gstreamer thinks it can't demux flv into a raw h264 stream that can be fed into the hardware. Either that's a bug in gstreamer or there's really something with h264-in-flv that makes in impossible to feed it to the h264 decoder.

It seems that the same issue exists also on 1.x (interesting huh :) ) version on Dreamboxes!

Working videos from veetle has the following:

 

width=(int)2400, height=(int)1920

An non working has the following:

 

width=(int)22974240, height=(int)12960000

 

/GstPlayBin2:playbin20/GstURIDecodeBin:uridecodebin0/GstDecodeBin2:decodebin20/GstFlvDemux:flvdemux0.GstPad:video: caps = video/x-h264, stream-format=(string)avc, pixel-aspect-ratio=(fraction)1/1, width=(int)22974240, height=(int)12960000, codec_data=(buffer)014d4033ffe1001b674d40339a760f0537febaf69e3420000003002000000651e3065c01000468ee3c80

 

Maybe the video witdh, height is way to big and the decoder refuses to play?

I don't think it's really surprising that gstreamer doesn't want to play that video (the second) ;)

Nope, resolution out of bounds... Bad encoder used?

It might be even on purpose, to prevent the streams from being played on open players.

Dear all,

 

 

My felling about width and height probably was correct.

 

I downloaded yamdi and removed all metadata from flv file.

 

yamdi -i flv_h264_1 -M -o flv_h264.fix

 

The resulting file is working on Dreambox now..

 

Spoiler

 

So what do you thing, is there a change to fix that somehow?

Bug 640483 - flvdemux: Video's width, height and/or framerate src caps added when present on onMetaData

 

This gstreamer bug seems to added the extra functionality in order to get width and height from flv metadata.

 

Maybe checking bounds fixes issue? (demux->w < MAX_WIDTH ? demux->w : MAX_WIDTH)

This means that I was probably right, in that the provider purposely inserts wrong values to prevent open players from playing it.

 

Maybe you can use ffmpeg to get rid of the flv container and put the contents in mkv or mp4, that will probably solve the issue.

Dear OpenPLi Developers,

 

 

I create a patch, compile the image and issue gone away with patched gstreamer!

 

I added the patch on gst-plugins-good_0.10.31.bbappend and gstflvdemux-max-width-height.patch inside gst-plugins-good_0.10.31 folder.

 

cat gst-plugins-good_0.10.31.bbappend

DEPENDS := "${@oe_filter_out('^(gconf|pulseaudio)$', '${DEPENDS}', d)}"

DEPENDS := "${@oe_filter_out('gtk+', '${DEPENDS}', d)}"



PRINC = "3"



SRC_URI += "file://audioparser-raise-ranks.patch \

            file://gstflvdemux-max-width-height.patch"



EXTRA_OECONF += "--enable-orc"



FILESEXTRAPATHS_prepend := "${THISDIR}/${P}:"

 

Please review this patch :)

Yes, probably they want to "mess" open players.

 

But this is a live stream! So using ffmpeg is not an option. Ignoring the metadata is the best option i think. When metadata doen't exist it will look on the bitstream data in order to extract the mentioned values.

Hello,

 

I created patch gstflvdemux-max-width-height.patch.txt using command diff -Nuar. What i am doing wrong?

 

PS. Patch was created before the latest changes on gstreamer.

In a simpler way:

 

if you want to produce a patch from your last commit:

git format-patch -n1

if you want to produce a patch series including your last 3 commits (for example):

git format-patch -n3

and the 3 patches will be named 0001-*, 0002-*, 0003-*.
