* lavf/webmdashenc: fix unchecked strftimeVignesh Venkatasubramanian2015-05-15
| | | | | | | | Fix unchecked strftime return value. This patch fixes Coverity CID 1295086. Signed-off-by: Vignesh Venkatasubramanian <vigneshv@google.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
* webmdashenc: Fix UTCTiming ElementVignesh Venkatasubramanian2015-04-28
| | | | | | | | | | | | | Remove the direct profile from UTCTiming element. Per DASH spec, direct profile value should be the time at which the request was made to the server and not the time at which the manifest was written. So ffmpeg cannot write this value. This patch removes the direct profile and write the UTCTiming element with the http profile only if a URL is passed as a parameter. Update the fate test to reflect this change.

* webmdashenc: parameter'ize minimumUpdatePeriodVignesh Venkatasubramanian2015-04-22

* webmdashenc: Add minimumUpdatePeriodVignesh Venkatasubramanian2015-04-22
| | | | | | | | | | | DASH spec requires the presence of either duration of the period or the minimumUpdatePeriod element. This patch adds the minimumUpdatePeriod element hardcoded with the value 0 as the manifest will never be updated for WebM DASH Live streams. Also updating the fate test reference file.

| | | | | | | | | | | Width, Height and Sample Rate should be in the AdaptationSet tag only if all the contained representations have the same width, height and sampling rate. Otherwise they should go into the Representation tag. This patch adds this functionality and a fate test for the same.

* lavf: Add WebM DASH Manifest MuxerVignesh Venkatasubramanian2014-07-15
This patch adds the ability to generate WebM DASH manifest XML using ffmpeg. A sample command line would be as follows: ffmpeg \ -f webm_dash_manifest -i video1.webm \ -f webm_dash_manifest -i video2.webm \ -f webm_dash_manifest -i audio1.webm \ -f webm_dash_manifest -i audio2.webm \ -map 0 -map 1 -map 2 -map 3 \ -c copy \ -f webm_dash_manifest \ -adaptation_sets “id=0,streams=0,1 id=1,streams=2,3” \ manifest.xml It works by exporting necessary fields as metadata tags in matroskadec and use those values to write the appropriate XML fields as per the WebM DASH Specification [1]. Some ideas are adopted from webm-tools project [2].
