How to estimate bandwidth / speed requirements for real-time streaming video ?
19 juin 2016, par Vivek SethFor a project I’m working on, I’m trying to stream video to an iPhone through its headphone jack. My estimated bitrate is about 200kbps (If i’m wrong about this, please ignore that).
I’d like to squeeze as much performance out of this bitrate as possible and sound is not important for me, only video. My understanding is that to stream a a real-time video I will need to encode it with some codec on-the-fly and send compressed frames to the iPhone for it to decode and render. Based on my research, it seems that H.265 is one of the most space efficient codecs available so i’m considering using that.
Assuming my basic understanding of live streaming is correct, how would I estimate the FPS I could achieve for a given resolution using the H.265 codec ?
The best solution I can think of it to take a video file, encode it with H.265 and trim it to 1 minute of length to see how large the file is. The issue I see with this approach is that I think my calculations would include some overhead from the video container format (AVI, MKV, etc) and from the audio channels that I don’t care about.

Is there any way to speed up video transcoding using Nvidea GPU ?
20 avril 2016, par evilpandaI am looking to transcode about 500gb worth of .mp4 video files to .flv format. I was wondering if there is any way my to gtx 970’s could speed up this process. Otherwise i’m stuck with using a single i7 4790k.
Is there any type of NVIDEA gpu conversion program available ?
Any suggestions appreciated.

ffmpeg android : change the speed of video and audio
2 octobre 2015, par JohnI am working on Android platform with ffmpeg, I’ve built the ffmpeg and run as ’run-time’ command for my android app.
I’ve tested some function like video trim, it’s working :
ffmpeg -i /sdcard/vpai/in.mp4 -ss 5 -t 5 -c:v copy -c:a copy /sdcard/vpai/out.mp4
merge video and audio, also working :
ffmpeg -i /sdcard/vpai/in.mp4 -i /sdcard/vpai/in.mp3 -c:v copy -c:a copy /sdcard/vpai/out1.mp4
But when I try to speed up the video, it’s not working, the command is :
ffmpeg -i /sdcard/vpai/in.mp4 -filter_complex '[0:v]setpts=0.5*PTS[v];[0:a]atempo=2.0[a]' -map '[v]' -map '[a]' /sdcard/vpai/output.mp4
I execute the exact same command on desktop, its working fine, but not working on the Android...
The error message :
Invalid stream specifier :"[v]".
Last message repeated 3 times
Stream map "[v]" matches no streams.Any one can help ?
