Please, I have two questions about playing accelerated video on RPi. I was thinking that the simplest way would be to modify the player included in "hello_video" . Btw., my video is without sound.
1. Is it possible to "seek" (i.e. to jump or skip) to certain time/frame in the video? Say I would like to play first 3 seconds of the video, jump to 10th second and continue playing from there.
2. Is it possible to pause the video? For example, I would like to display the first frame for 10 seconds, after which the video would start to play.
I don't really mind whether it is done using "hello_video", it's just I could not find any suitable player: omxplayer apparently cannot seek but perhaps there are other options?
I also found the post about seamless looping  but I don't understand how I could utilize it for the two problems above: it seems to read the video file to feed the decoder buffers and when it is at the end of file it starts from the beginning again. However, if I were to stop the video I cannot simply stop feeding the buffers, right? And I cannot simply fseek into the file because I don't know where to seek to because h264 frames are compressed.
Thank you very much in advance!
