APIsFAQs
Are there any restrictions on ApsaraVideo Live？
1. The service imposes no limit on the stream bit rate. It supports common resolutions and corresponding bit rates;
2. To prevent the stream from getting choppy, we recommend you adopt a bit rate no higher than 4Mbps.
Why do you use a live player to play m3u8 video file prompt error?
You need to add a policy file for cross-region access to the player, that is, adding the crossdomain.xml file to the root directory of the domain name where the video playback link is located and adding the permission for the domain name where the player is located.
Why can't the live push be played after it's successful?
1. Confirm whether the playback address is correct.
You can get the live console address at Console > Manage Domain Names > Domain Name Details.
The user-defined splicing rule of the playback address is 'Playing Domain Name' + 'App Name' + 'Stream Name' + "'_'" + 'Transcoding Template Name'.
2. Confirm whether the CNAME resolution of the domain name is configured to an Alibaba Cloud server.
You can query whether the CNAME resolution is effective or not through the ping command. If the ping command returns alikunlun*.com, it indicates the domain name CNAME resolution is effective. If the CNAME resolution is effective, execute the CNAME binding operation. For details, see
What do you do when you play video with Player?
Check whether it is a video source problem.
1. If it is a video source problem: A) Confirm whether the video source is normal to exclude the possibility of a transcoding problem. B) Confirm whether the stream frame rate and bit rate are normal to exclude the possibility of the stream transmission process.
2. If it is not a video source problem, check whether the player adopts software decoding. Call the 'setDefaultDecoder' interface in the SDK. If the parameter is 0, it indicates hardware decoding; if the parameter is 1, it indicates software decoding. Set the parameter to 1. Remove the original program first and restart the computer before re-installing the APK to avoid impact of data in the cache.
