i'm using library here , i'm using plugin here play video.

follow code:

controller:

[httpget] public actionresult streamuploadedvideo() {                 byte[] test = null;      using (var ctx = new entities())     {         var result = ctx.table.where(x => x.field == 4).firstordefault();          test = result.movie;          return new rangefilecontentresult(test, "video/mp4", "name.mp4", datetime.now);     } }

problem: when change video time (example: change time 1:00 10:00 minutes), face problem below:

google chrome: a network error caused media download fail part-way.

opera: the media playback aborted due corruption problem or because used features browser did not support.

image:

the rest of browsers fine. google , opera latest updated version of today's date: 07/04/2017

• micrososft edge - ok

• firefox - ok

• internet explorer - ok

• opera - error

• google - error

any solution ?

there issue code using datetime.now modificationdate used generating etag , last-modified headers. chromium (engine behind chrome , opera) range requests can conditional (which means can contain if-match/if-none-match/if-modified-since/if-unmodified-since) results in 412 precondition failed instead of 200 ok or 206 partial content. if underlying content doesn't change should using same date, this.

[httpget] public actionresult streamuploadedvideo() {     byte[] test = null;     datetime lastmodificationdate = datetime.minvalue;      using (var ctx = new entities())     {         var result = ctx.table.where(x => x.field == 4).firstordefault();          test = result.movie;         lastmodificationdate = result.lastmodificationdate;     }      return new rangefilecontentresult(test, "video/mp4", "name.mp4", lastmodificationdate); }
