speed with decimal point ignored

[NL5L]

Hello Krzyc,

building is going perfect now. We have a test system with Ubuntu 14.04 LTS and one with Ubuntu 16.04 LTS. But now, with the latest checkout (this morning) and the MAV9 (a couple of days ago) the speed function does not work anymore with a decimal point.

These commands working perfect: call 2 speed 1 call 2 speed 0 call 2 speed -1 call 2 speed 4 call 2 speed 32 call 2 speed -16

But these do not work at all: call 2 speed 0.25 call 2 speed 0.5 call 2 speed 0.75 call 2 speed -0.5

Also we have with the play command an FFmpeg error messages. Here the complete terminal output:

Hmm, it works for me even on current compilation. Are you sure you are using correct commands, because in attached log I see: call 2 speed 0.75

202 CALL OK

**call speed 0.33

400 ERROR**

So there is no channel number in last two command. Please try again and attach full log if error will occur.

Error message is from ffmpeg module which probably tries to load replay clip - I will look into it, because I see same error message on my system.

[NL5L]

Here a complete DEBUG output, and the call with 0.33 is indeed a typo...

log.txt

[krzyc]

Strange - everything looks good in log (except for ffmpeg error of course, but it should not impact playing of replay file). For me command like "call 2-20 speed 0.5" changes playing speed - it works in last MAV release and in currently compiled binary too.

[NL5L]

Hmmm... With our own builds it does not work... It just keeps playing the last speed. With your MAV 8 build it does work ! But not on Ubuntu 16.04... So it could be a library problem ? Did you check my versions with yours ?

[krzyc]

Strange. Maybe this is decimal separator problem - try comma instead of dot. I have this problem often in Poland, but not in CasparCG yet.

If not, try issuing "INFO 2-20" after "CALL 2-20 SPEED 0.5" and tell me what is returned in speed field or attach log file. Then try same for "CALL 2-20 SPEED 0,5".

I have just commited a change which should prevent FFmpeg from throwing errors for replay files, so you can pull it before next compilation.

[NL5L]

Hello Krzyc, today I started fresh with a clean new "git clone" and build the MAV 9. Still the same problem and the comma throws a big error ! The point seems to work, even in the INFO but the system keeps playing on the last speed which did work. Also I did try different configurations on every level, but I can not get a speed working between -1 and 1 (oh, 0 does work). log2.txt log2-trace.txt

[NL5L]

On my home computer I also tried to get a slomotion with a clean build. And also here I have exact the same problem... ...I have no idea what is different with your build. You did not use the script ? How do you build this project ?

[krzyc]

I have built project like this:

cd build
cmake ..
make

Comma will not work because regex in modules/replay/producer/replay_producer.cpp:277 is missing comma, but from log I see that speed was changed to 0.5 so problem is in something else.

So speed like -1, 2 or 3 work, but 0.5 or 0.1 not? Hey, I see that in modules/replay/producer/replay_producer.cpp:391 there is abs() function used for float type - this could be potential point of failure - there should by fabs() instead.

[krzyc]

Please update your source and try compiling again.

[NL5L]

Hello Krzyc, it seems to be fixed, great ! Thx !!

[krzyc]

Thanks.
