Ticket Name: TDA2: TDA2/AM574x video stream encoder throughput

Query Text:
Part Number: TDA2 Hello, I ask myself how much throughput the encoder for video streams can be reached on TDA2/AM574x devices. I would like store up to 8 video streams which we presumably encode best to keep the memory requirements and bandwidth to the storage medium as low as possible. From the description of the SDK (processors.wiki.ti.com/.../Processor_Training:_Multimedia) is not clear for me exactly how many streams can be processed parallel or which coding scheme has which restrictions. If I understand correctly, the VPE is used as input to the encoding. It exists on the SoC once. In the VPE description, I found nothing about multiplexing input data. However, the VPE seems to use the DSP cores for some of the encodings and those are available more than one time on some of the the mentioned SoC's. So my question is if anyone has experience in encoding more than one videostream on the mentioned SoC's? Best Regards Markus

Responses:
Hi, Yes, you can encode multiple video stream using different channels of 1 enc link. Currently 8 channel support is there. But keep in mind that IVA can only encode upto 1080p at 60FPS. Regards, Anuj
