Re: [FFmpeg-user] Stats
Hi Paul, I want stats with bitrates, fps... All information that ffmpeg shows while is running... But in a csv or similar file that let me do some statistical graphics. Thank you!

[FFmpeg-user] Stats
Hi! Is there a way to extract stats of encoding and decoding video into csv or similar format? I want to do several graphics to compare efficientcy in my project, but I don't know how to do...

Re: [FFmpeg-user] Stream diferent window of panoramic video
Oh thanks! That's what I want! One more question... do you know if it is possible to send ALL the image with two different qualities, a HQ for this window and LQ for the other part of the image. Thanks!!!

I need a way to tell the ffmpeg what zone I want in realtime... Like paramterization of coordinates to crop? If you know beforehand what to change, you can use expressions as parameters to the crop filter. Although I can't get it to work right now, the syntax would be: -vf crop=if(gte(t\,10)\,200\,100):if(gte(t\,20)\,100\,50) (At 10 seconds, the width changes from 100 to 200. At 20 seconds, the height changes from 50 to 100.) As you mention realtime: The zmq filter can dynamically receive commands to change parameters of other filters: -vf crop=640:480:100:100,zmq You then need to send commands to the zmq server with a tool like zmqsend: $ echo Parsed_crop_0 out_h 400 | tools/zmqsend $ echo Parsed_crop_0 x 150 | tools/zmqsend $ echo Parsed_crop_0 y 200 | tools/zmqsend These examples change the crop filter's parameters out_h, x, y, respectively. (I haven't found a lot of documentation on this, unfortunately. For example, I haven't figured out how to change two parameters at the same time.) Moritz P.S.: ffmpeg needs to be compiled with zmq support for this filter to be available. ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user
[FFmpeg-user] Streaming equirectangular panoramic video
Hi all! I'm doing a project that consist on transmission and visualization of equirectangular panoramic video in low low latency. The video is played from a browser into the Oculus Rift. The streaming and visualization is now going right. However, we want to improve the results sending only in High Quality the image that the users are seeing in Oculus. For that, we know which is the zone to send with High Quality and know which need to send in low low quality to improve the system. Is it possible to stream with the explained pipeline? The determined zones of the video that wants in High Quality is possible that are changing in the time. It can be parametrize? Thanks all and best regard. ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user
