WebM bitrate is not set correcty

[Frans]

In followup to ticket #295
http://mediamosa.org/trac/ticket/295

Original WebM file uploaded to VP-Core. Mime type is set correctly (video/webm), technical analysis is done correctly except for one thing: the bitrate. Transcode from WebM to flv (SURFmedia default preview) is going well. WebM file can be played in Chrome.

Another file in VP-core (original wmv) with a virtually empty transcoding profile (102) to webm. Transcode is going well, analysis is good, again a wrong bitrate is reported. Play succeeds again in chrome.

I have checked this issue with these Webm files:

These video files doesn't have bitrate according to ffmpeg. And it triggered this issue in vpx-analyse script.

Now I fixed it in that script.

[forgacs]

Test: Upload a Webm mediafile.

[Frans]

I did so with an upload of a WEBM video:

<app_id>33</app_id>
<asset_id>q1eUHtaF4YloCLh4hQW6dQZY</asset_id>
<mediafile_id>L2DYdrSQITjEsaiM9DE9WxvM</mediafile_id>

There still is empty bitrate info in the xml:

(<bitrate/>)

          <metadata>
            <video_codec>vp8</video_codec>
            <colorspace>yuv420p</colorspace>
            <width>1920</width>
            <height>912</height>
            <fps>23.98</fps>
            <audio_codec>vorbis</audio_codec>
            <sample_rate>48000</sample_rate>
            <channels>stereo</channels>
            <file_duration>00:02:00.38</file_duration>
            <container_type>matroska;webm</container_type>
            <bitrate/>
            <bpp/>
            <filesize>30810920</filesize>
            <mime_type>video/webm</mime_type>
            <is_hinted>FALSE</is_hinted>
            <is_inserted_md>FALSE</is_inserted_md>
          </metadata>

Also, the WLE doesn't know this video format:
Unknown format (matroska;webm)
But that is WLE related I guess.

These video files doesn't have bitrate according to ffmpeg. It is the reason, that there isn't bitrate in the technical metadata.
In the previous version of MediaMosa we saw bitrate = 0. That was wrong. And it is fixed now.
I suggest to move this ticket to MediaMosa X.X till ffmpeg will provide bitrate information from these files.

[Frans]

Ok. Fixed for now and moved to X.X for future modifications.
