Bug: Commands in BATCH not executing #1687
Description
Observed Behavior
CasparCG doesn't execute certain commands sent as a batch (via Python or console) under certain conditions.
Expected behaviour
All commands should always execute as long as they are valid.
Steps to reproduce
Assuming sample.mov is under media and minimal.html (see below for code) is under template
- Send the following command batch (via python or console):
REQ aaa BEGIN\r\nLOAD 1-10 sample\r\nCG 1-11 ADD 11 minimal 0\r\nCOMMIT\r\n
This is executed properly, video is loaded and first frame is shown / template is loaded and visible as well. - Send the following command batch:
REQ bbb BEGIN\r\nPLAY 1-10\r\nCG 1-11 PLAY 11\r\nCOMMIT
The HTML Template will play but the video stays frozen.
If in step 2 you send the following commands:
REQ ccc BEGIN\r\nLOADBG 1-09 qwert\r\nPLAY 1-10\r\nCG 1-11 PLAY 11\r\nCOMMIT
The HTML and video play properly. Please note, the media qwert does not actually exist. So just executing a nonsensical LOADBG command seems to fix it.
code for the HTML template
