Hi Arthur,I don't know if it can help, but I am encoding raw video (no compression whatsoever) using codec
AV_CODEC_ID_RAWVIDEO with pixformat AV_PIX_FMT_RGB24 in container .avi file.
The .avi generated are huge but high quality.I too, am looking for some lossless compression but I haven't found any way yet. I am a newbie to libav.

To: [email protected] Hello,I need to create a MP4/OpenH264 file from a series of images. Because the images are all of a technical nature, I need to have absolutely no compression. How can I achieve this with OpenH264?
When I used libx264 I set the number of b-frames to zero and it worked fine. I’m not sure OpenH264 even supports B frames given the discussion I saw here:
https://github.com/cisco/openh264/issues/1844If anybody could let me know what parameters I need to set to prevent any compression and not skip any frames I would appreciate it.
Thanks. -Arthur
