It would be nice if this example also captured and encoded audio.
I am not able to play H264 Video
When I record a 3 minutes movie, I found the movie is 02:10 long,but it actually is 3 mintues long when use movie player to play the record.
Excuse me, I have a question. When I import the H264HwEncoderImpl into my project and run, the file movie does not start from 0 second.
Hey @manishganvir,
Thanks for the great VideoToolbox example - this is the clearest/easiest to understand example I've found. Just wondering how to adjust the bitrate - the exported video is extremely low quality? Setting the kVTCompressionPropertyKey_AverageBitRate doesn't seem to make a difference, no matter what value I use - http://stackoverflow.com/questions/31458150/how-to-set-bitrate-for-vtcompressionsession
Also, you mentioned in another issue you are testing this with a streaming application - just wondering how you are using the encoded data to send over network? eg. udp, rtsp, any external libraries?
Thanks,
Trent
I'm using it on iOS for H.264 hardware encoding & decoding, it works fine, but when i put application into background and switch it back again,
the encoding and decoding will fail.
