Hi,
There is something strange about this sample file.
Checking it with mkvinfo I get the following:

+ Cabeçalho EBML
|+ Tipo de documento: webm
|+ Versão do tipo de documento: 2
|+ Doc type read version: 2
+ Segment, size 160099
|+ Seek head (subentries will be skipped)
|+ Informação do segmento
| + Escala do código de tempo: 1000000
| + Duração: 9.936s (00:00:09.936)
| + Muxing application: GStreamer matroskamux version 1.6.3
| + Writing application: GStreamer Matroska muxer
| + Data: Wed Mar 16 12:45:27 2016 GMT
|+ Pistas do segmento
| + Uma pista
|  + Track number: 1 (track ID for mkvmerge & mkvextract: 0)
|  + Tipo de pista: audio
|  + Track UID: 4966632641941336718
|  + Idioma: eng
|  + Nome: Audio
|  + Audio track
|   + Sampling frequency: 48000
|   + Canais: 2
|  + ID do Codec: A_VORBIS
|  + CodecPrivate, length 3979
| + Uma pista
|  + Track number: 2 (track ID for mkvmerge & mkvextract: 1)
|  + Tipo de pista: video
|  + Track UID: 6079372755166281868
|  + Nome: Video
|  + Pista de vídeo
|   + Pixel width: 640
|   + Pixel height: 480
|  + ID do Codec: V_VP9
|+ Cluster

while with a testing video generated by guvcview in my system (15.10) I
get:

 $ mkvinfo my_video-1.webm
+ EBML head
|+ EBML version: 1
|+ EBML read version: 1
|+ EBML maximum ID length: 4
|+ EBML maximum size length: 8
|+ Doc type: webm
|+ Doc type version: 2
|+ Doc type read version: 2
+ Segment, size 105668
|+ Seek head (subentries will be skipped)
|+ EbmlVoid (size: 163)
|+ Informação do segmento
| + Escala do código de tempo: 1000000
| + Muxing application: Guvcview Muxer-2014.04
| + Writing application: Guvcview
| + UID do segmento: 0xa1 0x89 0xf7 0xff 0x15 0x3b 0xda 0x94 0xfb 0xd1 0x2c 
0xa4 0x92 0xe2 0x3d 0xf9
| + Duration: 9.900s (00:00:09.900)
|+ Pistas do segmento
| + A track
|  + Track number: 1 (track ID for mkvmerge & mkvextract: 0)
|  + Track UID: 1
|  + Lacing flag: 0
|  + Default flag: 1
|  + Codec ID: V_VP8
|  + Tipo de pista: video
|  + Pista de vídeo
|   + Pixel width: 640
|   + Pixel height: 360
|   + Display width: 640
|   + Display height: 360
|   + Display unit: 3 (aspect ratio)
|  + Default duration: 40.000ms (25.000 frames/fields per second for a video 
track)
| + A track
|  + Track number: 2 (track ID for mkvmerge & mkvextract: 1)
|  + Track UID: 2
|  + Lacing flag: 0
|  + Default flag: 1
|  + Codec ID: A_VORBIS
|  + Tipo de pista: audio
|  + Audio track
|   + Canais: 2
|   + Sampling frequency: 44100
|   + Bit depth: 16
|  + CodecPrivate, length 3884
| + EbmlVoid (size: 191)
|+ Cluster

So the following lines:
| + Muxing application: GStreamer matroskamux version 1.6.3
| + Writing application: GStreamer Matroska muxer

instead of
| + Muxing application: Guvcview Muxer-2014.04
| + Writing application: Guvcview

Tell me that the file was not generated with guvcview. Not only guvcview has 
never used gstreamer, but the above strings have been hardcoded to guvcview 
code.
Also, see the video codec difference, the sample file is using V_VP9 while 
guvcview uses V_VP8.

Regards,
Paulo
