Hello, I am new to ffmpeg an have some question concerning the right usage of the ffv1 codec. I have images in PIX_FMT_RGB32_1 format which I would like to save with the ffv1 codec. Do I need to make a conversion to PIX_FMT_RGBA32 first, or is there an option to directly save in PIX_FMT_RGB32_1 format by an configuration option? I need to capture 8 live streams at once therefore performance is a critical issue for me. Alternatively is there another codec I could use for loseless compression which would allow me encoding without previous color conversion? It seems using something like HuffYUV whould lead to data loss through doing the color conversion. Finally I have a further question regarding saving of multiple video streams in a single avi, mpg or alternative container. Currently I am using a separate avi file for each cameras video stream, as I need to identify the stream with the hardware ID of each camera. The stream ID is not sufficient for me here as plugging a camera on a different firefire port leads to a different camera enumeration under windows, through which I would loose the correct assignments. Is there a possibility to store a string in a kind of per stream meta data array where I could save the hardware id of the corresponding camera? And if so in which structure could I find it?
Thanks for your help Cheers Christoph -- Aufgepasst: Sind Ihre Daten beim Online-Banking auch optimal geschützt?
