Most video files are playing with audio only

[Omer Akram]

I recorded a video file from Galaxy Nexus (using android) and put it on my Ubuntu phone(mako). When I start the video I can only listen to the audio i.e. no video.

1. Download the attached video and paste it in ~/Videos on the phone.
2. login to the phone from adb, unlock the screen
3. run: start application APP_ID=mediaplayer-app APP_URIS=~/Videos/VID_20131003_172149.mp4

The mediaplayer comes up there is sound but no video. This was tested on mako.

If I run
start application APP_ID=mediaplayer-app APP_URIS=~/Videos/VID_20131003_172149.mp4

on

forgot to add -> it works fine

[Sergio Schvezov (sergiusens)]

also, just in case, works in mir and surfaceflinger.

It doesn't work on mako with build 83. I tried with the video attached and other movies.

[Jim Hodapp (jhodapp)]

I haven't had time to look into this yet, but my hunch is that the issue is related to the GStreamer plugin caps for decoder plugin to accept vp8 decoding. On both maguro and mako, the list of supported decoders in /system/etc/media_codecs.xml clearly show that it should be supported:

<MediaCodec name="OMX.google.vpx.decoder" type="video/x-vnd.on2.vp8" />

Will take a look at this after I fix software rendering.

[Ricardo Salveti (rsalveti)]

The issue with the attached video is that our sink is currently only supporting NV12 (in caps), and the raw format that the decoder provides for this video is I420.

In theory we support that video just fine, we're just missing it from the caps. Jim is working on a fix to add a few extra known caps so we can have this video working as well.

[Jim Hodapp (jhodapp)]

Just needed to expand the caps of mirsink, and that got this video working. We should support many more output color formats now from various videos.

[Ricardo Salveti (rsalveti)]

Moving to inprogress again as we have another issue besides the missing CAPS, which is lack of software rendering in MIR.

For all videos that are decoded by software (either via gst or android), there will be no rendering at all atm. We just support rendering with hw decoders at this point.

*In MIR == in mirsink

[Justin Shafer (justinshafer)]

I don't know if this helps much.. but I get this in logcat while trying to watch a video in the browser.. it rolls through alot of codecs.
