Looking for video libraries for editing video on windwos/ios/azure service
15 juillet 2015, par sanyamWhich library would be a good bet in terms of ...
1. Richness in features (I want to create a video from short clips and images with effects and filters). Think auto videos created from Google Photos.
2. Extensibility - I would prefer using similar tech on IOS and Windows apps. Might have to offload some processing to a web service on Azure (windows or linux).
3. Programmability - An API is preferred over command line as it gives more flexibility and better error handling.Given all these options, what is my best bet ? I’ve only looked at ffmpeg till now, is there a better alternative ?

9 juillet 2013, par Computer_EngineerI want to evaluate H.264 and Vp8 videos using Evalvid framework, but when I reached to Mp4Box step(for packetize and hint track)there is no problem in H264 because Mp4Box support it , but it doesn't support Vp8 videos.

Thanks in advance.
