android - Select H264 Profile when encoding with MediaCodec and MTK Codec -

-

We have an Android app that encodes the video in H.264, all the previously tried Android devices, this baseline The profile I encode is what I need.

Codec Omx at Lenovo Yoga 10. MTK Video. Encoder.avc is This encodes the video as a high profile, which gives the problem for the receiving device.

I'm not using MediaCodec to see a way to use profiles.

Is there any way to do this? The codec claims to support the baseline profile but there is no way to use it. Is there any codec specific parameter for this?

Whatever you can try is the key profile in your MediaFormat , with the value of 1 ( OMX_VIDEO_AVCProfileBaseline ). If you do this, you probably have to add the key level along with your resolution to the value of a level (with the value of the OMX AVC level constant).

I 'I'm not sure if this codec really honors the requested value, but it may be worth a try.

Look for the setupAVCEncoderParameters function for an example on the setup process It appears in the input parameter for the profile key (from the media format provided by you Is copied), but if it exists then you use a level parameter, and depending on which level your resolution depends on. See for static values ​​that you can use for parameters.

But after checking the profile and level parameters, even after overriding the profile line, it looks like what was set. So either these rows have been removed from your device, or the encoder h264type.eProfile is completely ignored by the field.

If someone is found to have a source tree which is actually used, it is better to inspect the devices.

To choose an appropriate level for your resolution, take a look at x264_validate_levels as an example (but through level OMX_VIDEO_AVCLEVELTYPE constants MediaFormat needs to be passed.

Not sure that anything helps, but it is worth a try at least.

php - How can I cram 6+31 numeric characters into 22 alphanumeric characters? -

-
I have a 6 digit number and a 31-digit number (such as "234536" and "201103231043330478311223582826") that I The API needs to be crawled in the same 22-character alphanumeric field that uses PHP. I tried to convert each one to 32 (using custom code could not handle the base_convert () large number) and to connect with a single-character delimiter, but It only gives me 26 characters This is a restore API, so the letters should be URI-protected. I would like to do a database table cross with two references without reference to another reference value, if possible, any suggestions? Instead use a radix of 62. This will give you 22 characters for the top, 3.35 for the pre and 17.3 for the next. & gt; & Gt; & Gt; Math.log (10 ** 6) /math.log (62) 3.3474826039165504 & gt; & Gt; & Gt; Math.log (10 ** 31) /math.log (62) 17.295326786902177

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i...
