provider/zencoder: getting an error when trying to trigger encoding job with no height or no width about video-transcoding-api

[goldsteindavid]

After receiving the above error I started to get another when trying to post a zencoder preset with no height or no width. (Note: I was able to post these presets before I got the original error I wrote this ticket about.)

{
  "PresetMap": "", 
  "Results": {
    "zencoder": {
      "Error": "creating preset: local preset already exists", 
      "PresetID": ""
    }
  }
}

Here is my preset JSON:

{
  "providers": ["zencoder"],
  "preset": {
    "name": "QA_zencoder_webm_vbr_noheight",
    "description": "preset_zencoder_webm_vbr_noheight for QA.",
    "container": "webm",
    "rateControl": "VBR",
    "video": {
      "profile": "Main",
      "profileLevel": "3.1",
      "height": "",
      "width": "1080",
      "codec": "vp8",
      "bitrate": "1000000",
      "gopSize": "90",
      "gopMode": "fixed",
      "interlaceMode": "progressive"
    },
    "audio": {
        "codec": "vorbis",
        "bitrate": "64000"
    }
  },
  "outputOptions": {
    "label": "webm_720p"
  }
}

Hello @goldsteindavid I tried to reproduce this one with no success.

flv@~/Development/video-transcoding-api-examples cat preset_david.json

{
  "providers": ["zencoder"],
  "preset": {
    "name": "QA_zencoder_webm_vbr_noheight",
    "description": "preset_zencoder_webm_vbr_noheight for QA.",
    "container": "webm",
    "rateControl": "VBR",
    "video": {
      "profile": "Main",
      "profileLevel": "3.1",
      "height": "",
      "width": "1080",
      "codec": "vp8",
      "bitrate": "1000000",
      "gopSize": "90",
      "gopMode": "fixed",
      "interlaceMode": "progressive"
    },
    "audio": {
        "codec": "vorbis",
        "bitrate": "64000"
    }
  },
  "outputOptions": {
    "label": "webm_720p"
  }
}

and

flv@~/Development/video-transcoding-api-examples cat job.json

{
  "provider": "zencoder",
  "source": "https://nyt-video-tests.s3.amazonaws.com/animation_sorkin_mezz.mov",
  "outputs": [
    {"preset": "QA_zencoder_webm_vbr_noheight", "fileName": "output_david.webm"}
  ]
}

Triggering the job:

flv@~/Development/video-transcoding-api-examples curl -X POST -d @job.json http://localhost:8080/jobs

{"jobId":"7d3be3133c4dd4b8"}

I checked the output and things are good. Am I missing something?

also, this:

{
  "PresetMap": "", 
  "Results": {
    "zencoder": {
      "Error": "creating preset: local preset already exists", 
      "PresetID": ""
    }
  }
}

happens when you remove the presetmap but don't remove the preset, which raises another question.

@marzagao, @fsouza: since we have the concept of LocalPresets now, we can support all encoding services even if they don't have API's to handle presets. Do you guys think we should still expose PresetMaps?
