Linux/LINUXDVSDK-DM36X: DM368 dvsdk4.02.00.06 Video and Image encoder at the same time?


Tool/software: Linux

hi, i am using dvsdk4.02.00.06 to develope my dm368 i want to h264 encoder and jpeg image encoder work at the same time.but i got some error .just h264 encoder or jpeg image encoder independent work better.

the error like below:

1. ti.sdo.ce.alg.Algorithm - Algorithm_create> Assignment of alg resources through RMAN FAILED (0x7).

2. CV - VISA_create2> FAILED to create local codec.

3. ti.sdo.ce.image1.IMGENC1 - IMGENC_create> return (0x0)
 ti.sdo.dmai - [Ienc1] Can't open imaging encode algorithm

my cfg like below:

var osalGlobal = xdc.useModule('ti.sdo.ce.osal.Global');

osalGlobal.runtimeEnv = osalGlobal.LINUX;

are there someone give me some advice?

  • Hi Jery,

    H.264 encoder and JPEG encoder run on two different hardware engines. But they share the same resources like EDMA channels and some memory. Due to this reason, you might have to run it in sequence.

    But if you want to run them parallel,

    1. Use different scratch group id's. scratchGroup Id = 1 for H.264 encoder, scratchGroupId = 2 for JPEG in your .cfg file

    2. Release few EDMA channels. 

    3. set enableDDRbuff = 1 in h264

    Hope your are using latest codecs. Its recomended upgrade to latest from here :
