smoothstreaming chunk duration parameter before t

[DarkAnakin]

Hi, I had issue when parsing ism manifest file while chunk duration parameter is set before t.
Example:< c d="20000000" t="1204675194880260/>

Below is what I made to try to fix this.

static void XMLCALL
start(void *data, const char *el, const char **attr)
{
/***
***//
 for (; *attr;)
        {
          int startPTS_set = 0;
          if (*(const char*)*attr == 't')
          {

            uint64_t lt(atoll((const char*)*(attr + 1)));
            if (!dash->current_adaptationset_->segment_durations_.data.empty())
              dash->current_adaptationset_->segment_durations_.data.back() = static_cast<uint32_t>(lt - dash->pts_helper_);
            else
              dash->current_adaptationset_->startPTS_ = lt;
            dash->pts_helper_ = lt;
            push_duration = 0;
             startPTS_set = 1;
          }
          else if (*(const char*)*attr == 'd')
          {
            push_duration = atoi((const char*)*(attr + 1));
            if(startPTS_set==1)
            	break;
          }
          attr += 2;
        }

/***
**/
}```

Maybe not the right place to ask for it, but the stream that I want to play is encrypted, I have the right license but ffmpeg can't decode it. kodi log link here

thanks

No more issue with ffpmeg decoding when using agile branch.

As some manifest use repeated_count parameter I had to add it on the SmoothTree source.
Here all my changes.

static void XMLCALL
start(void *data, const char *el, const char **attr)
{
/***
****/
else if (strcmp(el, "c") == 0)
      {
        //<c n = "0" d = "20000000" / >
        uint32_t push_duration(~0);

        for (; *attr;)
        {
          if (*(const char*)*attr == 't')
          {
            uint64_t lt(atoll((const char*)*(attr + 1)));
            if (!dash->current_adaptationset_->segment_durations_.data.empty())
              dash->current_adaptationset_->segment_durations_.data.back() = static_cast<uint32_t>(lt - dash->pts_helper_);
            else
              dash->current_adaptationset_->startPTS_ = lt;
            dash->pts_helper_ = lt;
            push_duration = 0;
          }
          else if (*(const char*)*attr == 'd')
          {
            push_duration = atoi((const char*)*(attr + 1));
          }
          if(*(const char*)*attr == 'r'){
                 if(~push_duration){
                  		  uint32_t repeat_count = atoi((const char*)*(attr + 1));
                  		  for(uint32_t i=0;i<repeat_count-1;i++){
                  			  dash->current_adaptationset_->segment_durations_.data.push_back(push_duration);
                  		  }
                  	  }else{
                  		kodi::Log(ADDON_LOG_ERROR, "Repeated chunk with unspecified duration");
                  	  }
           }
          attr += 2;
        }
        if (~push_duration)
          dash->current_adaptationset_->segment_durations_.data.push_back(push_duration);
      }

Thanks for all the your great works.

Thanks, do you have a sample ism file for me to check it out?

Without repeated_count : http://hss-m04.live-aka.canal-plus.com/live/hssdvr/france2-hd/hddvr.isml/Manifest

With repeated_count : https://hss-c04-live-canalplus.akamaized.net/live/disk/reu-action-sd/sddvr.isml/Manifest

As said, the streams are encrypted, can't find one without encryption.

The last commit in master branch should solve the 2 issues.
Would be great if you can verify that it works (and close issue afterwards)
