Problem generating Quicktime files

[kroketor]

hi, I have a pipeline that creates files that works well when are open in VLC, but if i try to open they in quicktime they doesn't work. The quicktime bar moves but it doesn't shows any video. I tried also with the qtmux but i have obtained the same results. Its supossed that mp4mux and qtmux are both optimizied to create compatible archives with Quicktime so, what is the problerm? I'm doing something wrong?

This is the pipeline that i'm using:

appsrc name = source ! clockoverlay name = clock ! textoverlay name=text ! videoconvert name=conv ! queue name=queuestore ! x264enc name=encoder ! h264parse ! mp4mux name=muxer ! filesink name=videostore.

How are you generating the video stream, what format, etc.? Do you put
correct timestamps on it?

Maybe share one of the resulting files for further analysis.

Hi, I think you need to set the caps stream-format=avc and alignment=au

mp4mux already ensures that it doesn't get anything else, so h264parse
makes sure it outputs that if the input is something else.

Hi, i'm using OpenCV as source and i'm creating the files as mp4, the timestamp and the text are shown correctly when i open it in VLC. I used Mp4 Explorer on the file and it indicates mp42 as major brand, avc1 as coding and 244 as AVC profile but i don't know what it does mean. I also tried with qtmux to generate a mov file but i had the same problem.


Testemp4.mp4

Testemov.mov

Hi kroketor, I have the same problem as you. Did you find a solution?
